WEST TARUM CANAL IMPROVEMENT PROJECT
Loan and Project Summary
Borrower: Republic of Indonesia
Amount: $43.4 million
Terms: Repayable in 20 years, including 5 years grace, at the stan-dard variable rate.
ProjectDescription: The main objectives of the proposed project, which will serve
the agriculture and urban sectors, is to increase ruralincomes and food production through larger irrigationsupplies, and to improve Jakarta's urban living conditionsthrough increased and improved raw water supply. Towardsthese objectives, the proposed project includes (a) improve-ment of the West Tarum Canal (WTC), its major structures; (b)the construction of a pipeline from the canal to thePulogadung treatment plant; (c) strengthening the operationaland maintenance capacity and financial condition of theJatiluhur Authority; (d) technical assistance forconstruction supervision design, land mapping forreclassification and reassessment of taxation, protection ofraw water and improvement of safety measures at the JatiluhurDam. Agricultural beneficiaries will include mostly smallholders, with incomes below absolute poverty, in about 67,000ha at West Tarum, in West Java, while urban beneficiarieswill be Jakarta's residents whose highly inadequate watersupply will benefit from more and better raw water. Toimprove traditionally inadequate O&M funding, the projectprovides, on a pilot basis and for the first time inIndonesia, for increased cost sharing by beneficiaries inboth sectors. Urban beneficiaries through direct watercharges will pay the entire cost of supplying raw water whileirrigation beneficiaries will pay part of recurrent coststhrough properly channeled, appropriate, land taxes. Whilethese arrangements should ensure adequate O&M funding, andhence satisfactory operation and maintenance of the improvedcanal, there is some risk in terms of delays in putting theminto place, and consequently of inadequate funding or below-standard O&M. However, Government has already indicatedreadiness, to increase land taxes, to assign priority in theuse of a portion of these taxes for O&M, and to supplementsuch funds, as required, for adequate O&M. Also Jakarta'sMunicipal Water Utility has agreed to pay its share of O&Mand capital costs.
/a Including $4.8 million in tazes on civil works.
r. BACKGROUND
1.01 The Government of Indonesia (GOI) has requested Bank assistance forthe multipurpose West Tarum Canal rmprovement Project which will enhance irri-gation and urban raw water supply and consists of (a) improvement of the WestTarum Canal (WTC) to provide more water for irrigation of about 67,000 ha inthe West Tarum area, and for more raw water to the City of Jakarta; (b)construction of a 7.5 kmn water supply pipeline to connect the WTC andJakarta's Pulogadung water treatment plant; (c) strengthening the operacionaland maintenance capacity and financial condition of the Jatiluhur Authority(POJ), the agency responsible for operation and maintenance of project works;and (d) technical assistance for management and supervision of construccion,studies of future developmencs, land mapping for reclassification for tazationpurposes and strengthening of tax inspection offices, protection of raw waterresources, and improvement of safety measures at the Jatiluhur Dam.
1.02 The West Tarum Canal, one of Jatiluhur's main conveyance canals, wasbuilt in the 1960s to convey irrigation supplies to the West Tarum area and toaugment Jakarta's raw water suppLy. As demands for its water were only gradu-ally built up, it did not carry the full discharge it was designed for. Withwater demands nearly fully developed, the full discharge will be needed andstructural and maintenance improvements are required to enable the WTC toconvey it (para 2.05). Improvements, to be implemented under the proposedproject will facilitate meeting peak irrigation requirements of the entireservice area and Jakarta's raw water demands till the late 1990s whenadditional conveyance facilities will import water from neighboring riverbasins. The project was identified by Bank and FAO/CP missions in 1980,prepared by the Directorate Gereral of Water Resources Development (DCWRD),and POJ and their consultants between 1981 and 1984 with Bank assistance underIrrigation Project XV (Cr. 995-IND) and appraised by the Bank in September1984. The project has a high priority in COI's water supply and irrigationdevelopment plans. It should be supported by the Bank as it addresses highlyimportant sectoral issues and fits into long-term development strategies inthe agricultural and water supply sectors. The project will increase foodproduction and rural incomes, improve the use of land and water resources,provide additional, and better raw water to Jakarta, strengthen institutions,expand the dialogue with COI on cost recovery, and improve public health andoperation and maintenance (O&M).
Sector Background
1.03 Agricultural and Rural Sector. Covernment's major objectives forthe agricultural and rural sectors are to: (a) create productive employmentto raise incomes of the rural poor; (b) increase domestic food supply to keeppace with rising demand; (c) expand agricultural exports, particularly ofsmallholder tree crops; and (d) ensure productive, sustainable use ofIndonesia's land, water and other resources. Irrigation improvements and ashift to high yielding rice varieties, supported by fertilizers, almostdoubled rice production during the 1970s. Between 1970 and 1983, paddy pro-duction increased from 13 million tons to 23 million tons, 90X of it fromirrigated areas, which made Indonesia nearly self-sufficient in its major food
commodity. However. to maintain this position and offset growing demandthroughout the remainder of this decade, GOI pLans to invest an average ofabout S800 million a year. or about 8% of the development budget, upgradingand expanding irrigation systems and swamp developments.
1.04 Bank Role and Support Strategy for Irrigation. Since 1968, the Bankhas provided $1,018 miilion for irrigation projects in Indonesia. Theearliest Bank-supported projects were designed to repair major systems toquickly increase rice outDut. Later projects provided additional rehabilita-tion of existing syscems, drainage, flood protection, and tertiary networks.The most recent projeccs include measures to strengthen planning, programming,and budgeting capacity and managemenc information systems (Irrigation XV -Cr. 995 and XVI - Ln. 2113). and co build up the capacity of provincial irri-gation services in East Java Province (Irrigstion XVII - Ln. 2119), and ineight other provinces (Second Provincial irrigation Development - Ln. 2375).During GOI's Fourth Five-Year Development Plan (Repelita IV, 1984-89), theBank's involvement in the sector will emphasize institution building andaddress persistent sectorwide problems, such as operation and maintenancestandards and cost recovery. Lending will focus on:
(a) strengthening of national and provincial irrigation servi..es, andimproving their operation and maintenance performance; and
(b) a number of technically complex projects or projects which presentdifficult economic choices or in which Bank participation can mobi-lize significant cofinancing. Such projects include the West TarumCanal, the Jatigede Multipurpose Dam Project, and the Kedung OmboMultipurpose Dam Project.
1.05 The first five Bank-assisted irrigation projects have been1yomple-ted. Project Performance Audits have been issued for four projects,- and afollow-up ImpasF Evaluation Report is available for the first project(Cr. 127-IND).= ImpLementation delays and cost overruns, comnon to the fiveprojects, were caused by protracted bureaucratic procurement procedures,shortages of local funds, higher than expected inflation, design deficienciesand slow contractor performance. However, since cost increases were more thanoffset by higher rice prices, economic rates of return are expected to exceed40Z. The performance audit highlighted the need to improve operation, mainte-nance and replacement services (OM&R); provide technical and administrativesupport to water user associations; and promote efficient water use. Theseproblems are recognized in the strategy adopted for Bank assistance.
1.06 Water Supply Sector. Public urban and rural water supply systemsare relatively undeveloped in Indonesia, and serve only a small part of thepopulation. About 40Z of the urban and 18% of the rural population had direct

access to piped warer supply in 1981. The remainder obtains drinking waterfrom vendors, from shallow wells or rivers, at considerable health risk. TheGovernment's major objectives for the water supply sector are:
(a) Physical. The provision of basic water supply, sewerage and sarita-tion facilities, in accordance with technology appropriate to theLocal situation, cost-effectively, and with emphasis on the needs oflow-income groups;
(b) Institucional. The development of new, and the xcrengthening ofexisting. central and local institutions - including water supplyand sewerage public utilities - to improve their ability inplanning, implementing and delivering basic services; and
(c) FinanciaL. The creation of financially viable public utilities,which can provide services at affordable tariff levels and with atariff structure which allows recovery of operation, maintenance,and an appropriate portion of capital costs.
1.07 In 1981/82 the Government invested about Rp 65 billion (about $104million) in water supply and sanitation projects, amounting to about 1% of thedevelopment budget. During the last ten years, multilateral finance agenciesand bilateral aid donors have provided Indonesia with about $300 millionequivalent in capital and technicaL assistance reLated to this sector. Duringthis period, through a systematic approach based on limited levels of serviceand simple, standardized technology together with bulk procurement and decen-tralized implementation arrangements, COI has evoLved a substantial, low-costinvestment program, which focussed on lower income groups and served a widerange of communities. Government has also paid attention to strengtheningwater supply authorities in order to improve operational efficiency andachieve adequate cost recovery and better implementation performance. Now,%.nder the impetus of the International Drinking Water and Sanitation Decade(1980-90), cOI aims to scep up its earlier efforts and to significantlyimprove the level of access to safe water. Under Repelita IV, service targetsfor 1990 have been set ac 701 of the urban population and 55% of the ruralpopulation, at an average basic needs level (60 liters/capita/day (llc/d)minimum).
1.08 Bank Role and Support Strategy for Water Supply. The Bank's overallobjectives and strategies for the sector are consistrt with those of Govern-ment. As of end 1984, the Bank had made four loans - for the sector. Inaddition, substantial complementary investments in water supply and sanitationhave been supported by five Bank loans for the urban sector. Through theSecond Urban Development Project (Ln. 1336-IND) the Bank has had a significantinvolvement in the formulation of a comprehensive development strategy for the

Jakarta Metropolitan Area through the Jakarta Metropolitan Development Plan(JMDP). completed in 1981. Detailed studies of municipal and industrial waterdemands and improvement and expansion of Jakarta's wacer supply systems arecurrently in progress as part of the Jakarta Sewerage and Sanitation Project(JSSP). wich parallel Japanese Government assistance. A follow-up project isalso being prepared to rehabilitace Jakarta's existing water supply andupgrade its institutional framework.
II. THE PROJECT AREA AND PROJECT FORMULATION
A. The Project Area
2.01 The project area consists of two parts: the agricultural servicearea of the West Tarum Canal (the West Tarum area) And the metropolitan areaof Jakarta. The first part will benefit from increased irrigation supplieswhile the second part will benefit from increased raw water supplies.
The West Tarum Area
2.02 West Tarum. one of Java's most fertile, rice producing areas, formsthe western section of the 240,002 ha Jatiluhur irrigation project area. Itcovers a gross area of 87,000 ha,- or a net area of 67,000 ha, most of it inthe Bekasi District. It is bounded on the wez.t by Jakarta, on the north bythe coast, on the east by the Citarum River and on the south by the West TarumCanal. About 2 million people currentLy live in the West Tarum area, mostlyengaged in agriculture. There are two large towns, Bekasi and Cikarang, and anumber of smaller towns. Good internal road and rail connections facilitateyear-round mobility within the area as well as access to main population andcommercial centers. Due to its proximity to Jakarta's markets, the area has acomparative advantage in growing a variety of crops in addition to rice.
2.03 The climate of West Java, in which both West Tarum and Jakarta arelocated, is tropical. with an average temperature of 260C, relative humidityof about 80% and daily evaporation rates between 3-6 an. The average annualrainfall is 1,800 mm with about 75% falling during the November-April rainyseason, when monthly averages range between 130 and 400 mm. The remainder isscattered throughout the May-October dry season, averaZing between 40-125 mper month (Annex 1, Table 1). West Tarum's soils, like those of other partsof Java's north coa.t, have been formed by alluvial and colluvial depositsfrom a chain of volcanic mountains in the center of the island and are highlysuitable for rice production. The northern part of the irrigable area, closeto sea level, is flat and partly swampy, while towards the south, the groundrises several hundred meters. The general drainage is from south to north,varying in slope from about 0.02% at the coast, to 0.1% in the south. Fourmajor rivers, the Citarum, Cibeet. Cikarang and Bekasi, traverse the West

Tarum area, and in :he past their peak uischarges ilooded the northern, low-lying, lands. They were contained in the mid-1970s by extensive flood controlworks provided with Bank assistance (Irrigation Project V. Cr. 514-IND).
2.04 Most of the area has been under wet-season rice and secondary cropsfor generations, and about 45,000 ha are currently under dry-season irrigatedrice and about 3.000 ha, uncer secondary crops (Table 6.1). Based on 1983Agricultural Extension Service daca (Annex 1, Table 2). more than nalf thefarmers in the area hold less than 0.5 ha, nearly 80% hold less than I hawhile about 3% hold more than 3 ha. About 70X of the land is owner-operated,and about 20% is farmed by sharecroppers.
2.05 The West Tarum Canal The WTC traversing the area from east to westwas designed to convey from up to 85 cubic meters per second (cms) at itspumplift headworks at Curug, on the Citarum River to about 11 cms at itsterminal end, for irrigation and for municipal, industrial (M&l) supplies andflushing of rivers in Jakarta. Shortly after construction, earth slidesseverely damaged the canal and in mid-1970 it was repaired with Bank-Croupassistance under Irrigation Project II (Cr. 195-IND). 1982 a hydrometricsurvey or the canal and its structures uas carried out - which determinedthat the actual capacity et headwork pumps, the conveyance capacity of thecanal itself and of some of its major structures (a river crossing siphon anda tunneL and a siphon at the terminal) was significantly less than asoriginally designed (Annex 1, Table 8). This was partly because of designdeficiencies and partly because of inadequate maintenance. Despite thisdeficienc,. WTC's capacity was till now, adequate to supply West Tarum's,partially developed, irrigation demands. However, the relatively smalLcapacity of the terminal reach (6 cms instead of 11 cms) precluded releasesfor flushing of Jakarta's badly polluted Ciliwung river, which also serves asa main, open sewer. WTC's current capacity is not adequate to meet peak irri-gation demands of the entire West Tarum service area (as system rehabilitationunder Irrigation Projects V and XII, Lns. 514 and 1645-IND respectively isnearing completion), and raw water demands of Jakarta's expanding water supplysystems (Annex 1, Figure 1). An increase in the capacity of the WTC and itsancillary structures, proposed by this project, is the least cost, viable,solution to meet these demands (par&. 2.15).
Jakarta's Metropolitan Area
2.06 Jakarta, the notion's capital and its largest city, with an area ofabout 640 sq km, is located in northwestern Java. The city had an unprece-dented growth rate of 6% p.a. in the 1950s, and though its growth slowed toabout 4% p.a. in the 1970s. its population of about 7 miLlion in 1983 isexpected to increase to over 12 million people by the turn of the century.±'This rapid growth was not accompanied by a commensurate expansion of water

supply and other services. By 1970, municipal water suppLy systems coveredonly about 16Z of the city, and as a resuLt of a crash prcgram and the firstphase of a long range development, completed in 1975 and 1982 respectively,the service area nearly tripled in size (to about 44% of Jakarra's area) butonly about haLf the population in tne service area (about 2.1 miLlion)actualLy received piped water supplies. Even though the city has been engagedin an effort co increase piped wacer sup,lies most of Jakarta's populationcontinues to obtain water from other sources (para. 1.06). The Master Planfor Jakarta's water supply (JWSDP, _ICA. December 1984), envisages a gradualexpansion of the service area co about 70% of the city by 2005, supplying, atthat time, piped water to about 9 million people of the city's estimatedpopulation of 12 million.
2.07 About 90% of Jakarta's piped water is currently supplied from twotreatment plants, receiving raw water from rivers traversing the city. Theremainder comes from ground water (4X), from springs (4%), about 40 km southof Jakarta, and from a number of small 'mini' treatment plants located onlocal, small, rivers. The largest and oldest of Jakarta's treatment plants,Pejompongan (5.6 cms), is Located in the heart of the city, on the Banjir(Flood Control) Canal, whicb receives water from the Ciliwung River (Map18504). The second, never plant, Pulogadung (whose capacity of I cms iscurrently being expanded to 4 cms), is located in the city's eastern part, ontwo small creeks, the Sunter and the Cipinang. During low flows, limited,supplementary quantities of water are released into the Ciliwung and into theSunter from the West Tarum Canal, some 19 km upstream of Pejompongan and 7 kmupstream of Pulogadung. A major deficiency of Jakarta's water supply is anantiquated distribution system which, in 1980, delivered only 47% of the waterproduced by treatment plants. Most of the remainder was lost throughleakage. The poor condition of the distribution system also induces an inflowof contaminated ground water.
Water Resources and Requirements
2.08 Surface Water. The main water resource for all of West Java,including Jakarta, is the Citarum River. At the Jatiluhur Dam, near the townof Karawang, the Citarum drains a catchment area of 4,550 sq km with anaverage annual rainfall of about 2,400 mm, and an average annual runoff ofabout 6 billion cubic meters (BCM). In addition to a 2 BCM (active storage)reservoir at the Jatiluhur Dam, two additional dams, Cirata and Saguling, areunder construction upstream. Saguling, with a reservoir of about 610 MCM(active storage), is scheduled for completion in l9SQ 2nd Cirata, with areservoir of about 800 MCM, is scheduled for completion in 1988. TheJatiluhur reservoir is operated as a multi-purpose reservoir, serving irriga-tion, water supply and power. Saguling and Cirata will be operated primarilyfor hydropower generation, but will contribute to increasing Citarum's watersupply potential. In addition, smaller flows are contributed to the WestTarum area and to Jakarta by the Cibeet, Cikarang and Bekasi Rivers (Map IBRD18504), and exclusively to Jakarta, by the Ciliwung River and a number ofcreeks including the Sunter (Map IBRD 18505, and Annex 1, Table 3).
2.09 Groundwater. Groundwater is found in Java's coastal plain inquaternary, deltaic alluvial sediments that reach a thickness of over 300 m
-7-
and comprise clays, sands, silts and graveLs. There are three main aquifersin the coastal plain, though not always distinctly separated: a 50 m deepphreatic aquifer with its water table close to ground surface, underlain byclay layers separating two semi-confined aquifers, each about 40 m deep. Thephreatic aquifer is recharged by rainfall on the coastal plain and by riverstraversing it; the semi-confined aquifers are recharged mainLy at outcrops,some 15 km from the coast. and by infiLtration from the ohreatic aquifer. Itis estimated that in 1980 izarly 50% of greater jakarta's water supply, about200 HCH per year, was deriverd from groundwater through tens of thousands ofsmall wells. Of these, L.3C0 have been inventoried by the Directorate ofEnvironmental Geology. Present extraction exceeds the aquifer's safe yield,and piezometric levels have dropped to 20 m below sea level in the cencer ofpumped zones (North Jakarta). As well water becomes too saline for drinking,alternative water will be required. The proposed project, which will increaseraw water supplies to Jakarta, and an expansion of distribution systems (para1.08) address this issue.
2.10 Sediment. As a result of progressively denuded catchments, allrivers in the area carry ever increasing amounts of sediment, particularlyduring high stages. Most of the Citarum's sediments settle in the Jatiluhurreservoir, yet large amounts carried by the relatively small Cikao River, atributary of the Citarum downstream of the Jatiluhur Dam, enter the WTC at itsheadworks, while sediment carried by the three other intercepted rivers, theCibeet, Cikarang and Bekasi, enter at interception points. An analysis ofsediment data (Annex 1, Table 4) shows that, with properly designed andproperly operated and maintained sediment traps, most of the sediment thatwould have settled in canals could be trapped and disposed of before enteringthe canals where its removal is both difficult and costly. The data indicatethe impact of efficient sediment traps to be provided under this project, onreducing siltation in the canal system.
2.11 Bacteriological Water Quality. Bacteriological quality of drinkingwater in Indonesia, and in particular in Jakarta, is an issue of majorconcern. As a result of the city's high population density and lack ofcontrol on the use of resources, the quality of its surface and ground waterhas deteriorated progressively and the city's entire population is exposed atone time or another, to bacteriologically unsafe water. Water in shallowwells is contaminated from surface wastes, while rivers running through thecity, from which both individuals and treatment plants derive raw water, areincreasingly poLluted by human and industrial wastes. Highly fluctuatinglevels of pollution make it practically impossible to effectively treat suchraw watef,and as a result contaminated water has passed into piped watersystems.!/ Preliminary results of water quality monitoring, initiated in

November 1983 (under Irrigation Project XII, Ln 1645-IND), indicate that rawwater in the Bekasi-Jakarta reach of the WTC is of much better and treatablequaLity chan river (or creek) water reaching treatment plans (Annex 1. Table5). This finding has been incorporated in project formulation and design(para. 2.17).
2.12 Irrigation Requirements. The required capacity of the WTC has beenbased on peak irrigation requirements of the entire West Tarum area of some67,000 ha and on Jakarta's raw water requirements. Irrigation recuirementshave been calculated on the basis of recorded. representative. evapotranspira-tion rates, average percolation rates of 1 mm/day, and a simulated rainfall ofa 1:5 dry year, with an effectiveness of 45% during the growing season and70% during land preparation. An overall efficiency of 65% has been assumed,which, though higher chan the current efficiency of about 45%, is expected tobe achieved in the fucure through the structural and operational improvementof the WTC. Annex 1, Table 6 shows seasonal and peak irrigacion requirementsat turnouts from the WTC into secondary systems based on a common practice ofdividing the service area into 5 (occasionally 6) about equal size, rotationalblocks (golongans).
2.13 Jakarta's Water Requirements. Metropolitan Jakarta's municipal andindustrial (M&I) water requirements, given in Annex 1, Table 13, have beenbased on a projected population growth to 12 million by 2005, of whom about 9million would be served; on supplies ranging from 30 l/c/d for low incomegroups to 250 lIc/d for high income groups; and on an increase in distributionefficiency from about 54% at present to 75% in 2005, through rehabilitation ofdistribution systems. With little likelihood of increasing groundwatersupplies (para. 2.09), most of this water will have to come from surface waterresources. In addition to M&I water needs, an estimated minimum flow of about9 cms in Central Jakarta's rivers is required for flushing purposes, about10 cms in East Jakarta's, and about 4 s are required to meet ripariandemands downstream of diversion weirs._ To meet all these requirements,additional water will be imported from eastern, and to a limited extentwestern, basins, and treatment and distribution facilities will be expanded(Annex 1, Figure 1 and Map IBRD, 18505). High priority activities inJakarta's water supply development program are improving water quality andreducing losses (para. 2.19).
Water Management
2.14 The Jatiluhur reservoir is the largest and most important multi-purpose storage reservoir in West Java for irrigation, water supply and power.Operated since inception on forecast two-weekly demands, releases for the
8/ During the dry season, low river flows have to be supplemented. The WTCwill be able, after improvement, to supply up to 5 cms into the CiliwungRiver running through Central Jakarta, supplementing a low river flow of4 cms, while flushing releases for East Jakarta can take place only afteradditional water resources become available.

three main systems (West, East and North Tarum) have supplemented interceptedrun-of-the-river flows for irrigation in the Jatiluhur service area, includingWest Tarum, providing up co 6 cms to Jakarta, small quantities to a number ofsmall towns and industries, and generating about 55 SWh of power per month.Water management and reservoir operation studies, summarized in Annex L,Table 7, show that after 1988 (the completion of the Cirata Dam), theJatiluhur reservoir will be able to supply annually up to 4.8 BCM (supple-menting about 1.9 BCM from local rivers), to meet Jatiluhur's irrigation andJakarta's projected M&I demand, and provide about 300 MCM for flushing. Inreleasing this water, about 1,000 GWh of power (660 CWh firm) woyxd begenerated annually, with minor shortages in irrigacion supplies.- Additionalreservoir operation studies (under Irrigation Project X, Ln. 1578-IND) willoptimize the operation of reservoirs on the Citarum River to meet demandsbeyond the year 2000.
B. Project Formulation
2.15 The project has been formuLated to meet peak irrigation requirementsof the entire West Tarum area, Jakarta's raw water requirements till the mid-1990s, and improve water quality by works that are: (a) technically feasible;(b) least-cost solutions; Cc) ready as needed without requiring prolongedservice interruptions; (d) designed to deliver a reliable wacer supply ofacceptable quality; and (e) an integral part of long-range developments. Theimprovement of the West Tarum Canal meets all these objectives. An additionalconveyance canal (Canal #1, or the Tarum Jaya Canal) will be necessary in themid-1990s to supplement the WTC's capacity in supplying needed raw water.-which will utilize the remaining potential of the Citarum's water resourcesand augment Jakarta's raw water supply by an additional 35 cms. Works of theproposed project make maximum use of existing facilities, modifying andimproving them with minimal shut-down periods. Canal capacities will beoptimally increased mainly through surcharged water levels requiringrelatively minor modifications of canal cross-sections, and through structuralimprovements, including mechanically operated trashracks, additional siphonbarrels and larger desilting basins at river crossings.
2.16 Considerable attention was given in project formulation to upgradePOJ's institutional capacity for improved operation and maintenance (O&W) ofits systems and to ensuring adequate O&M funds through-cost recovery fromirrigation and water supply beneficiaries (paras. 5.05, 5.06). Technicalassistance has been designed to assist and train O&M staff in upgrading O&Mstandards and procedures. This activity will be aided by equipment, to befurnished under the project.

2.17 In view of a progressive deterioration of Jakarta's raw watersuppLy, a search for better quality water was initiated in November 1983 bymonitoring water quality along the entire raw water suppLy route. Interimfindings indicate that water in the WTC is of much better quality than chat inthe rivers feeding Jakarta's treatment plants. A study of alternative pLans(e.g., intensified treatment, poilurion control) showed that procected convey-ance (through pipelines) from points of suitable water quaLity in the WTC totreatment plants was the most feasible and cost-effective method for raw waterimprovement. This solution has therefore been adopted in planning the connec-tion between the WTC and the relatively new Pulogadung treatment plant, wheresavings in treatment costs alone justify such an investment (para. 7.04). Apipeline to Jakarta's older treatment plant at Pejompongan, whose distributionsystems are in poor condition, may be justified if phased in parallel withdistribution system improvements. and these are being prepared with Bankassistance under JSSP. In order to facilitate the appropriate timing of theseactivities studies of this pipeline have been initiated (under IrrigationProject XII, Ln. 1645-IND) and its design will be provided under this project.
2.18 Parallel Activities. In parallel with physical development, theproject has been formulated to strengthen executing institutions in implemen-tation management, and water quality protection (Annex IV). The project hasalso been formulated to provide for aerial photography and remapping ofJatiluhur's irrigated lands for reclassification and reassessment of landtaxes. Additionally, to verify farmers' payment capacity, a study of currentaggregate tax burdens on the farmer and land tax colLection methods has beeninitiated under Irrigation Project X (Ln. 1578-IND).
2.19 Following the findings of the study carried out under JSSP(para. 1.08), a project is being prepared with Bank assistance to rehabilitateJakarta's existing water supply systems, construct a pipeline to thePejompongan treatment plant, and improve the management and financialcapability of Jakartats public water supply utility.

3.04 Under the civil works component. cross-sections of the WTC will beincreased by about 30% bevond original design dimensions to compensate forrecorded. larger-than-foreseen fr-ction losses (Mannin n-.026, instead ofnn.020 in original design). Excepc ac che nead reach this will beachieved by increasing the depth of flow by 25-30 cm and by increasing thewidth of the canal by about 5-i0% by restructuring the Left berm. Originaldesign capacities, recently (1982) surveyed and revised capacities are givenin Annex L, Table 8.
3.05 FoLlowing structural improvements will be carried out under theproject:
(a) Inlet Bay and Headworks. A new inlet bay co the Curug pumpingplant will be constructed by dredging an old river channel,immediacely upstream of the existing inlec. tt will beconnected to the forebay of che pumping plant through a newtrashrack structure, and equipped wich mechanicaL rakes andtrash removal facilities. Turbine discharge penstocks andoutlet gates will be rehabilitated and subsurface drainage ofthe forebay of the plant will be improved;
(b) Sediment traps at the Cibeet, Cikarang and Bekasi diversionswill be considerably widened and deepened;
(c) Two additional siphon barrels and a new, mechanically rakedtrashrack will be constructed at the Cibeet River crossing;
(d) A new streamlined inlet, equipped with mechanically rakedtrashracks will be built at the Cawang siphon (near WTC'sterminal) and the 1 km long outlet tunnel into the CiliwungRiver will be lined; and
(e) Minor structures. turnout gates from WTC will be heightenedand defective gates replaced; about 20 cuLverts will beextended; drain inlets into the WTC between Bekasi and Jakartawill be closed and a parallel drain and culverts will beprovided.
3.06 The proposed connection between the WTC and the Pulogadung treatmentplant will be a gravity pipeline, 2.0 m in diameter, starting near km 63 + 630(bridge #49), at a metered inlet, and inflow will be controlled from thetreatment plant. The inlet structure will allow a future connection of thepipeline to Canal #1 (Tarum Jaya). The pipeline will foLlow the Buaran Creek,crossing an Industrial Estate at Pulogadung, and will terminate at theexisting inlet to the treatment plant. Prestressed concrete appears to be the

cheapest material of construction of the pipline but a final selection of thepipe's material will be made after bidding (schedule for Kay 1986).
3.07 Definite engineering plans and cost estimates of all civil workswere prepared under Irrigation Project XII (Ln. 1645-IND) on the basis offinal design of the WTC. Additional work on detail, design and contractdocuments is well in hand and scheduLed for completion by July 1985. Weeklywater quality measurements in the WTC, which have been carried out sinceNovember 1983, are being continued. Detail design of the pipeline toPulogadung has started and is scheduled to be completed in October 1985 forbid invitation in December 1985. Land acquisition for limited rights-of-wayrequirement along the canal is in progress and negotiations with land ownersare in progress. Due to limited requirements, no major delays in constructionare expected. Similar activities for the pipeline right-of-way will commenceupon completion of alignment surveys. This activity has been prograumd inconstruction schedules.
Consulting Services
3.08 Local and foreign consulting services will be provided to assist theJatiluhur Authority in construction management and supervision, in upgradingO&M, and in designing additional conveyance facilities. Consulting serviceswill also be provided to continue and expand the Authority's training programin O& of tertiary systems to include more water users, and in preparing plansfor the protection of the quality of WTC's water conveyed to Jakarta. Con-sulting services will also be provided to assist in the preparation ofsuitable maps for reclassifying irrigated rice lands in the Jatiluhur projectarea. Estimated man-months of various assignments are suimarized in Table 3.2below and detailed in Annez 1, Table 9. The cost of the assistance package isestimated as $5.83 million for 247 man-months of expatriates, 620 man-monthsof local professionals and 1,044 man-months of local technicians. Assuranceshave been obtained at negotiations that consultants, whose qualifications,experience, terms and conditions of employment are acceptable to the Bank,will be engaged not later than the dates indicated in Table 4.1. The contractfor consulting services for construction supervision is being currentlynegotiated with invited consultants, scheduled for coooencement of work inSeptember 1985 (one month ahead of commencement of construction).
Implementation Methods and Schedule
3.09 The project will be implemented by parallel activities in variouscanal reaches over a 6-year period starting in the fall of 1985, with prioritygiven to enlargement of the Bekasi-Jakarta reach, to facilitate an earlyincrease in municipal and industrial (M&I) water supply (Table 4.1).Implementation plans specify dredging of the canal for the removal ofaccumulated material below the water surface, or, where widening of the canalis called for, mechanical excavation for the removal of material above thewater surface. All this will be done with minimal service interruptions.Structural work at the canal terminal, which requires service interruption fordewatering of the canal at that point, will be implemented during sufficientlylarge flows in the Ciliwung so as not to affect operation of the Pejomponganwater treatment plant.

All contracts, orders andreceipts will be kept at least two years after loan closing; and auditedreports will be forwarded to the Bank within nine months following the end ofeach fiscal year.
H. Environmental Impact
3.17 The project will make an important contribution in improvingJakarta's water quality and in reducing endemic water-borne diseases byincreasing and improvinig raw water supplies to the city. The project willalso contribute to preserving and protecting the West Tarum Canal and theproposed Tarum Jaya Canal from pollution by initiating studies and preparingfor protective measures. It will likewise contribute to improved sanitaryconditions by providing water for the flushing of the city's rivers.
IV. ORGANIZATION AND MANAGEMENT
A. Executing Agencies
4.01 Construction and Design. Construction of physical works under theproject and the design of future developments will be implemented by "PROYEKSERBANGUNA JATILUHUR," a project unit for Jatiluhur's multipurpose develop-
- 21 -
ment, in DGWRD's Department of Irrigation I (DWI I). This unit, previouslyknown as PROSIJAT, and reporting to Jatiluhur's Directorate, has beenresponsible for the rehab.Litation of Jatiluhur's irrigation system (underIrrigation Projecr II, Cr. 195-IND), for construction of flood control works(under Irrigation Project V, Cr. 514-fND) and is nearing compLetion of itscurrent assignment for tertiary construction (under Irrigation Project XII,Loan 1645-IND). The unit has an amply staffed technical department butrequires technical assistance in construction supervision arid management, andin designing new developments. Water quality protection plans will be pre-pared under the supervision of DGWRD's Directorate of Planning and Programming(DPP).
4.02 Operation and Maintenance. The Jatiluhur Authority (POJ) isresponsible for the operation and maintenance of all infrastructure (includingthe Pulogadung pipeline) upon completion of construction. The Authority wasestablished in 1970 to operate and maintain the muitipurpose Jaciluhurproject, including the dam, power Dlanc, irrigation and raw wacer supplysystems. The Authority employs more than 2,000 peoDle, (exclusive of dailyworkers) in O&M. Maintenance activities, handicapped by chronically shortbudgets, and carried out usually during slack periods of agricultural seasons,have to be significantly upgraded to orovide continuous and reliable water asrequired by Jakarta's water supply, and operation procedures require similarlyupgrading to reach optimal utilization of available water resources.
4.03 Land Taxation. The Directorate of Land Taxes (IPEDA) within theDirectorate General of Taxation in the Ministty of Finance, will beresponsible for mapping, demarcation of landholdi.ags, reclassification oflands for taxation purposes and reassessment of land taxes. Assurances havebeen obtained at negotiations that GOI will cause the implementacion of saidmapping, reclassification and reassessment in accordance with theImplementation Schedule (Table 4.1).
B. Current and Planned Procedures
4.04 The West Tarum Canal is currently operated on the basis of calcula-ted irrigation demands, and agreed raw water supplies to Jakarta, within theconstraints of WTC's carrying capacity and available supplies. DeLiveries arereviewed and agreed every two weeks by POJ and PDAM, the Jakarta's watersupply utility (paras. 4.08-4.09), and maintained throughout the operationinterval, even if changes in hydrologic conditions occur in the interim. Thisapplies to all of Jatiluhur's irrigation systems (north, east and west) whichare operated through operational subcenters, and an operational center atCurug. West Tarum's subcenter, located at Bekasi, is supported by threesections, each operating a reach of che WTC between two local rivers. Most ofthe flow in these rivers is diverted into the WTC to meet irrigation and rawwater demands, and when these flows are inadequate, supplemental water isreleased from the Jatiluhur reservoir. This procedure, which till nowsupplied up to about 67X of WTC's service area, appears to have worked well,but wit.. the forthcoming completion of all irrigation systems in the commandarea and increasing supplies to Jak&rta, the operation of the system has to bemore responsive to hydrological changes to achieve an optimal use of waterreleases from storage. Appropriate operation would have to be supported by

frequently updated and processed rainfaiL data from catchments of localrivers, flow forecasts to facilitate adjustments in diversions at Curue andoptimized releases from Jatilunur (above firm power reieases). This wouldrequire improved communicacions between gauging stations and subcenters,between subcencers, and improving and upgrading of data collection andprocessing. The project addresses this need by providing operational hardware(microcomputers and communicacion equipment), software, technical assistanceand training of operation staff.
4.05 Maintenance. As a result of POJ's recurrent shortage of funds(para. 5.01) and cumbersome, manual maintenance procedures (which requiredewatering of the system which interrupts water supply), the WTC has not beenmaintained in optimal operating condition. Between annual clean-outoperations. silt, originating in intercepted rivers nas been accumulating inconveyance systems, reducing capacity (para. 2.10). Xanual maintenanceefforts could not be intensified without interrupting Jakarta's raw watersupply, and inadequate funds precluded the acquisition of appropriatemechanical equipment. The project addresses this issue by providing forinfrastructural improvements and larger and more effective sediment trapswhich will reduce the inflow of sediment into the canal (Annex 1, Table 4),and for suitable, small dredgers and ancillary equipment to facilitatemaintenance without interrupting supplies.
4.06 The project also provides technical assistance in training POJ'sstaff in effective O&M of the WTC and of headworks pumps. Staff at theJatiluhur Dam will be trained in adequate monitoring, processing and inter-preting of dam safety data (including piezometric levels, embankment settle-ment data, deflection and settlement data of the intake tower and power plant)and in adequately maintaining safety equipment. Assurances have been obtainedat negotiations that GOI shall cause the inspection of the Jatiluhur Dam,reservoir banks and associated structures at 3 year intervals with soundengineering practice and to remedy without delay any deficiencies which mayendanger the safety of the dam and its structures. GOI will propose appro-priate arrangements for the Bank's review not later than December 31, 1985.
4.07 O&H Funding. POJ derives operating and maintenance funds fromgenerated revenues, from budgetary allocations from Central Government andfrom Local Government contributions. In 1982 about 50% of POJ's revenues camefrom the sale of power to the State Power Authority, Perusahaan ListrickNegara, (PLN); 32% came directly from Central Government; 11% came fromCentral Government funds chAnnelled through Local Government; 3% came from thesale of raw water and 4Z from miscellaneous sources (e.g. tourism and variousservices). Though these revenues are higher than they were in previous years,they still fall short of current O&M requirements (para 5.01). POJ has, in thepast, also benefited from additional funds made available for capitalinvestments particularly in rehabilitation of irrigation systems, which werenot always clearly distinguishable from routine maintenance. In the future,these resources may no longer be available. As raw water supply increases,O&M requirements become more stringent and more costly and POJ's futurefinancial posture will be precarious,unless additional revenues can begenerated (para. 5.01)
- 24 -
C. Raw water Utilization
4.08 PDAM-DKI Jaya. PDAM. established in 1968. i1s a semi-auconomousutility of DKI Jakarta responsibLe for cveration, mainEenance and expansion ofJakarta's water supply. Raw water Drovided by the WTC is treated by PDAM'splants and is distributed through its sVstem. ?DAM is headed by a PresidentDirector who is assisced bv three airectors responsibie ior engineering.business, and administration (Fig. 2, Annex 3). The utility has about 2.000employees. Despite a low water discribution efficiencv. PDAM has beenfinancially proficable in the pasc years with an average annual net surplus ofabout Rp 2 billion during 1981-83 (Annex 2. Table 3).
4.09 PDAM has a long-cerm expansion plan for its service area and in viewof a shortage in local water resources, is importing increasing quantities ofwater from severai river basins (paras. 2.06, 2.13). New treatment plants(Pulogadung II, Buaran. and Cakung), are expected to come on line (Annex 1,Fig. 1) and discribution systems are in a process of expansion. The Bank isassisting PDAM (under JSSP. Ln. 2236-IND) to prepare a project wich willstrengthen its implementation and management capacity. During negotiations,assurances have been obtained that GOI will cause Cipta iCarya (the DirectorateGeneral of Housing, Building, Planning and Urban Development) and PDAM (a) tocomplete the expansion of the Pulogadung Treatment Plant by September 1988 andits distribution system prior to September 1989. Also, COI confirmed, atnegotiations that by September 1985 GOt would employ consultants to assistwith planning the improvement and rehabilitation of Jakarta's water supplydistribution system which is scheduled to commence in September 1986.
D. Monitoring and Evaluation (M&E)
4.10 Monitoring and evaluation of projects during and after implementa-tion are important tools in managing existing projects ard in planning forfuture development. These activities may be generally classified into fiveinterrelated levels to be implemented by various agencies Es shown in Annex 2,Table 14.
4.11 In the Jatiluhur project area, monitoring of physical and financialprogress has been routinely carried out by PROSIJAT; however, monitoring andevaluation of water management and crop production requires considerableimprovement. Farm incomes in irrigated areas and the socioeconomic impact ofirrigation has been evaluated in the past by university groups on an ad hocbasis, and a systematic design for and effective implementation of M&E includingall five levels still needs to be established. Assurances have been obtainedat negotiations that GOI will cause DGWRD's DOI I to submit a comprehensiveM&E scheme for project works construction and will cause POJ under theguidance of DPP to submit to the Bank for comment by July 1986, a comprehen-sive M&E scheme of O&M, crop production, farm income, changes in land tenure,distribution of project benefits, and commence its implementation by July1987.

V. ALLOCATION AND RECOVERY OF PROJECT COSTS
A. Background
5.01 POJ's weak financial position is a major cause for inadequatemaintenance of irrigation systems under its jurisdiction (para. 4.05). As ofJune 30, 1982, POJ had accumulated a net loss of about Rp 32 billion (Annex 2,Table 1). This loss occurred in POJ's irrigacion and water supply operations,primarily due to an absence of revenues from irrigation, and inadequately Lowrevenues from the sale of raw water to jakarta. Increasing revenues from rawwater charges (para. 5.04). and channeling increased land taxes to O&M (para.5.06), will improve POJ's finances. As, however, incremental revenues will begenerated gradually, additional funds will have to be made available by GOIfor O&M (paras. 5.08 and 5.09).
B. Project Cost Allocation
5.02 Annex 1, Table 13 illustrates cost sharing between beneficiaries.It shows the allocation of investment and recurrent (OH&R) costs to the twobenefitting user groups: irrigation and M&I water supply. Improvement costsof joint facilities of WTC have been allocated in direct proportion to thecapacity each component requires. This resulted in an allocation of 70Z ofimprovement costs to irrigation, and 30% to water supply. The cost of WTC'ssingle-use components, e.g., the Bekasi-Jakarta reach and the PulogadungPipeline, serving only raw water supply, has been allocated entirely to watersupply. Seventy percent of the investment and replacement cost in O&Mequipment, which will primarily benefit raw water supply, has been charged tothis beneficiary. On this basis, of the total estimated investment of about$67 million (including contingencies and engineering but excluding technicalassistance), $39 million (58%) has been allocated to M&I raw water supply, andabout $28 million (42%) to irrigation. Annual O&M costs are prorated on thesame basis, but adjusted at given intervals to actual expenditures.
C. Cost Recovery
Raw Water SuppLy
5.03 POJ's raw water supplies to Jakarta, Bekasi and a number of indus-trial consumers are paid for currently in accordance with negotiated rates.Payments by PDAM for raw water delivered to Jakarta were fixed in 1976 by theGovernor of Jakarta at Rp 19.8 million p.a., with an annual increase of 15% tocompensate for inflation. In 1981, the payment was about Rp 40 million($53,000) or about Rp 0.4 per cu m (Annex 2, Table 2). This rate was too lowto meet O&M costs for raw water supply, let alone recover investment costs. Anew rate of Rp 10/cu m of raw water has recently been established, but has notyet been implemented.
5.04 Estimated raw water charges and payment capacity. With an aim ofrecovering allocated OM&R costs and capital investment, raw water chargesshould be determined on the basis of actual costs as illustrated in Annex 1,
- 26 -
Table 13. PDAM should repay actual construction costs and pay recurrent O&Mcosts (Annex 1, Table 14). Data given in Annex 1, Table 17 show that PDAMwill be in a position to pay these costs, amounting to less than 10% of itsestimated operational costs, through larger revenues from increased watersupply, and through, conservatively estimated, higher water tariffs. The costof the Pulogadung pipeline will not burden PDAM as it will be offset bypotential savings in the cost of water treatment (Table 7.2).
5.05 POJ/PDAM Agreement. Prior to loan negotiations POJ, as supplier ofraw water, and PDAM as user of raw water, entered into the followingagreement, accepted by the Bank, which wiLl become effective by, July 1988, orthree months after POJ commences supplying 11.6 cms to PDAM's treatmentplants, whichever earlier. The agreement specifies that:
(a) PDAM will pay POJ annually 100X of the allocated raw water supplycosts (including operation, maintenance and replacement) and repaycapital investments allocated to the DKI Jakarta raw water supply,according to principles given in para. 5.02;
(b) Allocated capital costs shall be paid yearly throughout a 30-yearperiod at a 12% per annum interest rate; annual OM&R costs shall bereviewed every three years by both parties and adjusted on the basisof actual costs;
(c) POJ will ensure the delivery to PDAM of an uninterrupted supply ofwater of an agreed quantity, peak discharge and quality;
(d) POJ shall keep separate accounts for (i} recovery of capital costs,(ii) replacement of O&M equipment, and (iii) O&M of WTC and of thePulogadung pipeline. These accounts will be annually audited andaudited reports shall be sent to PDAM and the Bank for coments.
5.06 During negotiations, GOI agreed that any proposed amendment to theagreement be furnished to the Bank for comments.
Irrigation
5.07 Government revenues in Indonesia's agricultural and rural sector aremainly generated through, by current standards relatively low, land taxes(IPEDA) (para. 5.08). There are no direct irrigation water charges inIndonesia, except contributions by farmers of irrigated lands to village watermasters and water user associations, for the upkeep of tertiary irrigationsystems (para. 5.07). The lack of adequate revenues in the irrigation sub-sector, unjustified in view of significant benefits attributable to irriga-tion, imposes an unduly heavy burden on GOI in financing new developments andin operating and maintaining irrigation systems. To ease this burden,revenues in the irrigation subsector should be increased, commensurate withbenefits, and for expediency should be channelled to maintenance of irrigationsystems. In view of a long tradition of farmers' perceived inalienable rightto free surface water, and various political and social constraints,Government is not ready, at this time, to impose water charges, and the mostpracticabLe way of increasing revenues appears to be an increase of land taxes
- 27 -
by applying existing laws and regulations 121 linking IPEDA with, inter alia,rice production and rice prices. Towards channeling locally generated fundsfor O&M of main and secondary irrigation systems, a dialogue has beeninitiated with the West Java's local government, and an agreement has beenreached in principLe (para. 5.09). IPEDA's funding of other rural develop-ments would not, and indeed should not, be curtailed, and farmers paymentcapacities would be considered in assessing higher tax rates (para. 5.10).This is the first time that this approach is being explored in Indonesia, andits application is expected to be gradual. The dialogue initiated under thisproject will be pursued in coming irrigation projects, and broadened to otherprovinces.
5.08 Farmers' Contribution. Farmers are expected to operate and maintaintertiary irrigation and drainage systems, and in the project area, areexpected to contribute 25 kg of paddy per ha per crop, and about five days oflabor per year to their local water user association (WUA). In most irrigatedareas, including the project area, these associations have not been active andhave not been able to improve the operation and maintenance of tertiarysystems. Consequently farmers have been reluctant to contribute theirshare. With a view to improving chis situation, the Jatiluhur Authority hasbeen training irrigation officials in ensuring reliable irrigation supplies tofarmers and in proper O&M of tertiary systems (para. 6.04).
5.09 Land Taxes (IPEDA). IPEDA (luran Pembangunan Daerah), literally acontribution for rural development, is commonly collected from farmers byprovincial governments through village heads and allocated at the Kabupaten(District) level. The tax is used for a variety of rural developments but isusually not used for the upkeep of main and secondary irrigation systems,which have traditionally been financed by Central Government. In West Java,the provincial government, which in the past retained 10% of IPEDA collec-tions, has recently rechannelled 8% to district governments and about 2%, orabout Rp 200/ha (1% of the current requirement) for O&M of Jatiluhur's mainand secondary irrigation systems. Under current regulations, IPEDA isassessed in accordance with the size of landholdings, the productivity 13 assof the land, value of production, and may be reassessed periodically.However in practice, most lands are under assessed. Current IPEDA rates,shown in Annex 2, Table 4, were established in 1979 and have not beenmaterially increased since. Under the impact of previous and currentinvestments in irrigation, rice production will increase to about 10 t/ha(Table 6.1) and this will raise IPEDA for an average 0.8 ha holding from acurrent assessment of Rp 13,300/ha (Table 5.1) to about Rp 29,000/ha(according to Annex 2, Table 4, using the 1979 price of Rp 95/kg) or Rp50,000/ha (using the 1985 paddy price of Rp 165/kg, Annex 1, Table 18).Clearly such an increase in IPEDA can only be implemented gradually, and inthe interim GOI will have to provide required funds for adequate O&M throughbudgetary allocation (para. 5.09).

5.10 During project appraisal, GOI has agreed in principle to update landclassification and IPEDA assessment in Jatiluhur's irrigated area and toearmark a portion of IPEDA revenues for fRincing O&M of main and secondaryirrigation systems in the Jatiluhur area. Assurances were obtained atnegotiations that:
(a) GOI will cause POJ to update maps of the Jatiluhur service area forreclassification of IPEDA by December 31, 1988;
(b) GOI will cause the Directorate of IPEDA to reclassify irrigatedlands and reassess IPEDA rates in the Jatiluhur service area (about300,000 ha) in accordance with agreed terms, and specifications byMarch 1990;
14/ See project file.
- 29 -
(c) cOt will cause the Wesc Java Provincial Government to allocateincremental IPEDA collected in the Jatiluhur service area, to thefinancing of O&M of main and secondary irrigation systems in sucharea in accordance with a schedule, acceptable to the Bank, to befurnished to the Bank by December 1988.
(d) cOr will, at all times. make available adequate funds for O&M ofJatiluhur's irrigacion systems, and those required co supply toJakarta reliable raw water of acceptable quality, as agreed betweenPOJ and PDAM, supplementing funds which may become available fromother sources.
5.11 The above-mentioned activicies will be facilitated by two technicalassistance schemes: (a) Land remapping for reclassification and IPEDA re-as-sessment (assisted under this project) and (b) studies on farmers' tax burdenand improving IPEDA collection efficiency (assisted under Irrigation X,Loan 1578-IND).
Cost Recovery Indexes
5.12 On the basis of projected raw water charges shown in Annex 1,Table 14, the cost recovery index for the water supply component is about 106%at a 10% interest rate (the local opportunity cost of capital). The costrecovery index of the project's irrigation component is about 11.5Z at asimilar interest rate which is in line with other irrigation projects inIndonesia. Detailed calculations of these indexes are shown in Annex 2,Table 5. The relatively low cost recovery index for irrigation is due to therelatively small amount of incremental taxes expected from irrigationbeneficiaries as a result of this project.
VI. ACRICULTURAL PRODUCTION AND FARM rNCOMES
A. Agricultural Production
6.01 The improved West Tarum Canal will provide additional water to therehabilitated irrigation systems in the project area, which will facilitate anexpansion of irrigated areas in the dry season, and a concomitant increase inproduction of rice, soybeans and maize. Changes in cropping patterns, yields,and production with the project are summarized in Table 6.1, with detailsgiven in Annex 2, Tr'.le 8.
6.02 Cropping Patterns, Yields and Production. In the project area,paddy is, and will remain, the dominant crop during the wet (November - April)and dry (May - October) seasons. Secondary crops, such as food crops andvegetables, will continue to be grown as second or third crops after the mainpaddy crop. In farm analyses, major crops of maize and soybeans represent allsecondary crops. The main contribution of the project will be an expansion ofthe cropped area during the dry season. This area, currently comprising about

48,000 ha can expand to about 55,000 ha as distribution systems are completed.Further expansion to 67,000 ha (Table 6.1) will take place as the capacity ofthe WTC is increased. Paddy yields in the project area have been steadilyincreasing and with the full impact of Irrigation Projects V and XII areexpected to increase to about 5 t/ha during the wet season and to about4.8 t/ha in the dry season. The project is not expected to achieve a furtherincrease in paddy yield, but yields of major crops of maize and soybeans areexpected to increase by 0.2 t/ha. The project's (1990) incremental productionof about 82,000 tons of paddy, and 22,000 tons of maize and soybeans isprimarily the result of increased cropping intensity. Most of this productionwill be absorbed by the Jakarta market and will substitute for imports, aslong-run Indonesia's demands will exceed national production.
6.03 Supporting Services and Post-harvest Facilities. Farmers in theproject area are experienced food crop growers. Most of the project area has
- 31 -
been covered under BIMASVINKAS a national guided credit and production inten-sification program for wet and dry season rice crops, and agriculturalsupporting services provided to farmers are generally adequate. There are 16rural cooperatives (BUUD/KUD) and 114 branches (kiosk) which supply farminputs, and about 660 mills/hullers, which are adequate for present andexpected future production.
6.04 Water Users Associations. Water users associations (WUA) haverecently been established for aLl tertiary systems in the project area. How-ever, most of them are inactive and need to be developed (para. 5.07). Duringnegotiations, DCWRD clarified :hat training of water users would be providedthrough a national program and C0I wouLd provide specific details by October1985. In addition, the burden on farmers of paying various formal andinformal taxes in the area will be studied (para. 5.10).
B. Farm Incomes and Payment Capacity
6.05 In the farm income analysis, budgets have been developed for farmsizes of 0.3 ha, 0.8 ha, and 1.5 ha representing smaLl, average, and largefarms in the project area. The farm budgets of sharecroppers are based ontraditional sharecropping arrangement, whereby landowners pay for taxes andabout half of the prcduction costs, receiving in return half the production.It has been assumed that farm fmilies consist of 5 persons, providing about50 man-days per month, supplemented by hired labor in peak seasons, and areemployed off the farm during slack seasons. Financial prices of all farminputs and outputs have been used in farm budgets, which include all incurredproduction costs except farm family labor. Estimated farm incomes for thesetypicaL farms are summarized in Table 6.2 and detailed in Annex 2, Table 11.
6.06 As shown in Table 6.2, incomes of all farms will rise as a result ofthe project. A significant income increase (50-852) for all farm groups willresult from massive improvements under Irrigation Projects V and XII, and asmaLler increase (12-18X) as a result of the proposed project. After sub-tracting an equal minimum living allowance from net incomes, average and Largefarm holders will have a considerable surplus for payment of incrementaltaxes. Smellholders' surplus will remain negative, albeit considerably lessso than before and their payment capacity for additional taxes is limited.The size of Landholding is reflected in IPIDAs. current rates, and small-holders are assessed a lower rate than holders of larger farms, however, thedifference is too small to adequately reflect respective payment capacities.The subject of an equitable distribution of all farmers' tazes based onfarmer's payment capacity would be pursued in our continuous dialogue withCOI.

VII. BENEFITS, JUSTIFICATION, AND RISKS
A. Project Benefits and Beneficiaries
7.01 The proposed project will increase food crop production, improvewater supply to Jakarta, reduce foreign exchange expenditures for rice andother food grain imports, and enhance employment and income opportunities inthe agricultural sector. Major benefits and beneficiaries of the project aresumnarized in Table 7.1. At full development, an incremental quantity ofabout 82,000 tons of paddy and about 22,000 tons of soybean and maize will beproduced annually which will save CO1 about $22 million each year in foreignexchange by reducing imports. An equivalent of 15,000 full-time farm jobs willbe created through crop intensification every year. Civil works of theproject will generate some 4 million man-days of construction labor during the5-year implementation period. Jakarta will receive a progressively increasing
- 33 -
amount of raw water with improved quality which will generate benefits asshown in Table 7.2. About 140,000 rural families and 700.000 urban familieswill benefit trom the project directly and indirectly. Against this,investment costs per family are about $120 per farm family and about $29 perurban household.
7.02 The proposed project is the least-cost solution to achieve thesebenefits and the continuation of water resource developments in which theJatiluhur Authority progressively supplies an increasing portion uf Jakarta'sraw water. The project will upgrade POJ's O&M capabilitv and address costsharing of investments and recurrent costs by beneficiaries. The project willprovide for farmers training in O&M of tertiaries and in increasing irrigationefficiencies. It will also provide for che protection ot water quality.These considerations. though not quantifiable, are important benefits of, andjustifications for the project.
B. Economic Justification
Major Assumptions Used in Economic Analysis
7.03 Irrigation Benefits. Only the direct and quantifiable benefits ofirrigation attributable to this project are considered in the economicanalysis. These are derived from incremental farm production (rice, maize andsoybeans) valued at economic prices (March 1985 constant dollars) net ofincremental production costs. A detailed analysis of farm production benefitsii shown in Annex 2, Table 11. About 80% of irrigation benefits areattributable to paddy production from an incrementally irrigated area of about17,000 ha in the dry season and the remainder are attributable to secondarycrops including soybeans and maize. These production increases are directlyreLated to WTC'J improvement, and are distinct from product on increases as aresult of other irrigation developments (Irrigation Projects V and XII).
7.04 Benefits of Municipal Water Suppl. Benefits of the municipal watersupply component can be classified as: a) increased raw water quantity madepossible through the enlargement of the WTC; and (b) improv. raw waterquality by a protected conv! H nce through a pipeline connecting WTC to thePuLogadung treatment plant.- The project is part of a lei t cost systemexpansion plan to meet projected water requirements in Jakarta. Without theproject, the most Likely alternative to improving water quality is to continu-ously increase chemicals in the treatment process to cope with increasinglypolluted row water. This will increase treatment costs and decrease plantefficiency. The economic benefits of the proposed pipeline to Pulogadung fromsavings in chemicals and plant efficiency, is about Rp 2.4 billion in 1990 andincreases progressively (Table 7.2). These savings aLone would generate aneconomic rate of return (ERR) of about 19X for the proposed pipeline, andabout 8Z for the water supply component as a whole.
15/ Until another pipeline is built for the Pejompongan treatment plant,water from WTC will be delivered to this plant through the Ciliwung Riverwith only a marginal impact upon raw water quality at that plant.

/a Foreign exchange costs of incremental fertilizers and chemicals for cropproduction have been taken into consideration.
/b Most below poverty line.
- 35 -
7.05 Benefits also arise from increased water quantity. Alternativelocal surface and ground water resources are limited, increasingly contam-inated, treatment is costly and often ineffective, and large quantities ofwater transfer from neighboring river basins cannot be readily developed tomeet near-future requirements. The allocated development cost (excludingpipeline costs) of Rp 11.0/cu m (Table 7.2) is the price paid by PDAM for rawwater and is passed on to consumers. Current retail tariff averages Rp 250/cu m.Therefore Rp 11/cu m, 4% of the currea1t retail tarrif, may be considered as aminimum estimate of benefits. There is substantial consumer surplus at thistariff and there are also considerable public health benefits which have notbeen quantified.
7.06 Labor Pricing. The project is located in the vicinity of Jakarta,and there is considerable population pressure in the project area. This isreflected in the large proportion of landless laborers (about 30Z) who arehighly underemployed. The opportunity cost of unskilled labor is low at anestimated Rp 700lday.-& The shadow wage rate nas therefore been assessed atabout 70Z of average farm wages of about Rp 1,000/day, and at about 50% of thecommon construction labor wage which is estimated at about Rp 1,400/dayexcluding costs of transportation, housing, and other facilities.
7.07 Agricultural Prices. All farm inputs and outputs in the economicanalyses as well as in farm budgets are valued in conscant March 1985prices. Economic prices for rice, maize, soybean, and fertilizers are basedon January 1985 world market price forecasts for 1986, 1990 and 1995 by theBank's Commodities and Export Projections Division, adjusted for transporta-tion, processing, and handling costs to farm gates, as shown in Annex 2,Tables 6 and 7. For reference, financial prices for all commodities fromactual farm gate prices are also listed in these tables. In the projectanalysis, projected prices for 1986, 1990 and 1995 represent prices during1984-1989, 1990-1994, and 1995 and onwards, respectively.
7.08 Foreign Exchange. The official exchange rate of US$1.00 = Rp 1,100is considered to reflect the value to the economy of the foreign exchange usedin the project, and hence a standard conversion factor of 1.0 has beenadopted.
7.09 Economic Life. The project's economic life is assumed to be30 years under adequate O&M, based on the expected life of major projectworks.
7.10 Economic Costs. Total project costs have been adjusted to economiccosts by eliminating discrepancies between financial prices and real oppor-tunity costs. The following are the major adjustments (see Table 7.3):
(a) exclusion of expected price escalation and taxes;
16/ Average daily income from various marginal activities, based on anongoing Bank study.

(b) exclusion of costs of future studies which have no impact on the projectbenefits;
(c) application of a shadow wage ratio of 50Z to unskilled construction labor(para. 7.06); and

Sensitivity AnaLysis
7.12 Crossover (or switching) values2l7 for a 10 discount rate werecalculated for a number of variables crucial to the success of the project.Table 7.4 summarizes differences between the crossover and appraisal valuesfor a number of criticaL variables. Since the project has two technicallyseparable components, the WTC and the pipeline, the sensitivity analysisfocuses on these components.

the WTC, indicating that the improvement is economically viable even ifinvestment should increase by 19OZ or incremencal paddy production shoulddecline to nil. Similarly, the viability of WTC's improvement is relativelyunaffected by a reduction of benefits from secondary crops or water supply.It will remain marginally viable even if the economic life of the WTC is onlyeight years. The ERR of the pipeline wouLd be reduced to IOZ by a 61%reduction of savings in chemicals. A 194Z reduction in savings of treatedwater would be required to reduce ics ERR to lO. The pipeLine will bemarginally viable even if its economic costs increases by 87% or its economiclife decreases to 12 years (including three years construction).
C. Risks
7.14 As discussed above, there are no major risks inherent in the pro-posed project except that OLK may be below standard if funds are inadequateand/or management is inefficient. However, OI has indicated readiness toincrease land tazes and assign priority in their use to OLM; PDAM has agreedto reimburse POJ for all incurred expenditures related to raw water supply andGOI has agreed to supplement these funds, as required, for adequate 06M. Inaddition the following steps have been taken to further reduce risks:
(a) the project will initiate a progrm aimed at protecting the qualityof WTC's water resources;
(b) PDAM's share of OUI expenditures will be paid at quarterly intervalsto POJ, in accordance with the agreement between PJ and PDAM;
(c) Incremental IPEDA collections will be applied to Oh and the balanceof funds needed for adequate 01K will be provided by OI throughbudgetary allocations
(d) PDAM's allocated 0&K contributions will be adjusted every threeyears in accordance with actual, incurred expenditures;
(e) POJ will procure under the project appropriate O01 equipment toensure reliable, continuous raw water supply. Funds will be setaside to enable equipmeat replacement and procurement of spares; and
(f) the project will provide technical assistance which will upgradePOW's technical and managerial capability in carrying out 01K works.
