From the west the territory is bordering with the Gulf of Finland.

Figure 2. Location of Municipality “Vistino rural settlement” and Kingiseppskiy Municipal District at

map of Leningrad region

Kingiseppskiy municipal district is located in the western part of Leningrad region.

District borders:

from the north‐west and north boundary runs along the shore of the Gulf of Finland;

from the east ‐ along the administrative border with Lomonosovskiy and Volosovskiy districts;

from the south ‐ along the administrative border with Slantsevskiy district;

from the west ‐ along the state border of the Russian Federation and Estonia.

Geographical location defines a special position of the Kingiseppskiy district in Leningrad region.

Almost half of the administrative boundaries of Kingiseppskiy district coincides with the state border of the Russian Federation. The District borders with two countries of the European Union ‐ Estonia and Finland. The border with Finland is exclusively marine. Kingiseppskiy District has the largest water area of the Gulf of Finland in comparison with the others districts of Leningrad region. The district also includes islands located there in. The largest of them ‐ Hogland, Greater and Lesser Tuters, Powerful (Lavensaari), Seskar and Small (Penisaari).

7

The coastline is about 126 km. It runs along the Gulf of Narva, Koporskaya Bay and Luga Bay. Luga Bay is suitable for navigation of large ships. This part of the Gulf of Finland has a short period of freeze‐up and the depth is suitable for navigation that allows constructing large‐scale modern seaport. Within the area there are lower reaches of two navigable rivers ‐ Narva and Luga, those are connected with each other by another navigable river ‐Rosson.

The district is a frontier area and important highways of federal importance (namely roads and railways) cross the territory. Federal highway "St. Petersburg‐Tallinn" goes though Kingisepp town.

Total area of Kingiseppskiy municipal district is 290 800.00 hectares. Municipality "Kingiseppskiy municipal district" includes the following settlements: Kingiseppskoe, Ivangorodskoe, Bolshelutskoe, Vistinskoe, Kotelskoe, Opol’evskoe, Nezhnovskoe, Pustomerzhskoe, Ustlugskoe, Falileevskoe. The total population is 81 700 people (4.5% of the total population of the Leningrad region).

Geographical location of the district contributes to its social‐economic development. Economic condition of the district is at a high level and is one of the main in the region. The district has a wide profile of industrial orientation and is based on its own natural resources and has a high economic potential. Economic development of the district is above the average of the region. There is well‐developed network of regional roads, those connect almost all settlements with central roads. Great influence on the development of the district has the construction of Ust‐Luga seaport.

1.2 Territory land tenure and condition of general plans Vistino rural settlement is located on a peninsula along Sojkinskaja Luga Bay of the Gulf of Finland. The northernmost point of the peninsula Soikinsky is cape Kolgomlya. In the central part of the territory there is Sojkinskaja hill, maximum depth is about 136 meters above the sea level. About 60% of the land is covered by forests, mostly coniferous.

Natural complex area “Soykinsky coast”

The territory supposed to be a sanctuary is on a northwest extremity of the Soykinsky peninsula.

Hydrological natural area “Rosson river valley”

The territory supposed to be a sanctuary is the river Rosson connecting deltas of the Luga river and Narva river. The area is unique on the hydrological regime. Rosson connects Narva river with the Luga River that flows in 15 km to the East.

Suggestions to organize of the ethno‐cultural reserve in the area of the Luzhitsy

village

Ethnographic capacity of the Kingisepp municipal area is defined by accommodation on its territories of the people of different cultures – the Russians, the Vod, the Izhorians, Finns‐Ingermanlands

The Izhora ethnographic museum in Vistino village

The ethnographic museum located on Tsentralnaya Street, in the village of the Vistino of Kingisepp region of the Leningrad region, Izhora plays one of leading and significant roles in the course of preservation of original cultural values of the Finno‐Ugric people under the name of Izhor.

2. HYDROGRAPHY The territory of the municipal area has the developed hydrographic network belonging to the basin of the Baltic Sea, presented by the Luga and Koporsky Bays of Gulf of Finland of the Baltic Sea, the rivers and lakes. Regarding nourishing conditions the hydrographic network of the territory belongs to the East European type with the maximum spring snow high water and the small autumn rain. Seasonal distribution of a drain is uneven and more than 40% happens in April‐May. In winter the nourishment of streams and lakes mainly happens at the expense of underground waters that promoted by proximity of glint, delineating the Ordovician plateau formed by karst limestone and dolomite.

2.1. Resources of underground waters

Figure 3. typical lithological section area near the Vistino

Within the Kingisepp area 6 water‐bearing complexes and formations are widespread. By results of calculations of expected operational stocks of underground waters for the water‐bearing formations, executed by PMA "Sevzapgeologiya", stocks for the Kingisepp area are the following:

• expected reserves of fresh waters of the Lomonosov water‐bearing formation within the lowland are equal 4 thousand m3/d; • expected reserves of fresh waters of the Lomonosov formation, Cambrian and ordovician complexes are equal 460 thousand m3/d.

The existing water intake does not exceed 10% of perspective stocks. However nature of distribution of resources of fresh underground waters and specifics of hydrogeologic conditions of certain territories of the area does not allow counting on full on drinking water supply of the area with underground waters near consumers. So, the northern part of the area, including the Vistino settlement, is not provided with fresh underground waters which by quantity and quality could be a source of the centralized water supply. The Lomonosov water‐bearing forming emerges under quaternary deposits in northern part of the area. Underground waters are pressure head, pore‐deposit. Fresh waters with a mineralization 0,2‐0,6 g/dm3 are widespread in places of exits of the formation under quaternary deposits. In process of immersion the mineralization increases to 2, 5 g/dm3. The centralized water well‐field is not made; operation is conducted by single wells. Most surface waters that are relatively easy get, can have radioactive contamination.

2.2. Resources of surface waters Belaya river is used as a source of drinking water for Vistino village. Belaya river belongs to the basin of Habolovka river and refers to the 3rdclass of Division B in accordance with the classification of water objects according to GOST 17.1.1.02‐77. Belaya river flows from wetlands of coast Luga Bay, located five kilometers from the coastline of the Gulf of Luga Bay. Soils in the catchment area are boulder loam, sandy loam, sand with gravel and pebbles, underlained by Silurian karst limestone. Valley slopes are from medium steep to very steep. Their height increases downstream from 1.0‐1.5 m to 6.8 m.

In hydrological matter Belaya rivers an unexplored river. Characteristics of minimum flow is obtained by estimated calculation. According to the certificate SU "St. Petersburg CGMS‐R" minimum estimated natural 30‐day water consumption is 95% of Belaya river supply during the period of summer‐autumn base flow is 0,020 m3/sec. During the winter base flow water consumption is close to the summer‐autumn values.

Spring flood at Belayariver, by analogy with the small rivers of this region, usually begins in late March ‐ early April. The average duration of the flood is 15‐20 days. Flood peak is in the mid of the April. Water raise level of average spring flood above the average winter base flow is 0.6‐0.7m. Spring flood recession lasts about 45‐50 days. Usually the end of the flood starts in early June.

Water protection zone width is 50 m. Riverside protection zone is set based on the slope of the shore of the water object and is 30 m for reverse or zero bias, 40 m for slopes up to three degrees and 50 m for the slope of three or more degrees. The strip of land along the shoreline of the water object for public usage (the riverside) is 5 m. Table 2.

Lakes

Within the boundaries of the municipal area there are located 11 lakes. The largest of them are: Kopanskoe, Glubokoe, Lipovskoe, White, Babinskoe, Habolovskoe. Kopanskoe and Glubokoe lakes are on border with MF territory "Vistino joint venture". The Kopanskoelake has length of 7 km. Water of lakes is low‐mineralized, of a hydrocarbonate class. The general mineralization of water is low and in Babinskoe lakes it is 41.3 mg/l, Habolovo ‐40.8 mg/l, Sudachye ‐ 37.1 mg/l.

3.2. General characteristics of water supply and wastewater systems

Currently, the territory of the settlement, except village Vistino, has no central water supply and sewage systems. History of construction of a centralized water supply and sewage systems at Vistino.

Table 8. Stages construction Year Stage 1936 Construction of water intake, water treatment plant and water distribution networks1982‐1989 Reconstruction of water intake and construction of sewage treatment plant, gravity flow

collector, treated water distribution networks and sewage system for water tower (currently out of use), step up pumping stations

2008‐2012 Construction of networks to base "Efesk" and hotel "NOVOTEK". Compound of village houses for water supply purposes have on their individual plots dug wells to a depth of 8 meters.

Main water supply for Vistino village is organized from surface water source – Belaya river. Water purification is performed on water intake treatment plants (WTP) "Belaya Rechka". The capacity of plant is 400 m3/day. Structure of facilities and their technical condition will be indicted hereinafter. Wastewater from consumers of Vistino village via gravity sewer collector flow to biological treatment plant of project capacity 1670 m3/day and after treatment and disinfection is discharged into the Luga Bay of Gulf of Finland of the Baltic sea. The sewage system is in very bad condition, which entails environmental degradation and violate water protection zones of rivers and their tributaries. Other localities of the settlement do not have a centralized pumping domestic sewage. Inhabitants enjoy raking or outhouse toilets, which don’t have appropriate degree of waterproofing, that leads to pollution of aquifers. In very rare cases, on the private plots bio toilets are installed. Now days the water supply and sewage objects are of municipality property of the settlement and are exploited by the "Sevzapkommunservis" company under the lease agreement.

At the same water pipe in the area of Smenkovo village there is intermediate concrete treated water tank (TWT) of 500 m3 volume (CWT). Due to significant changes in elevation 2 step up pumping stations were constructed in Vistino village. First step up pumping station does not operate because there is no necessity as after TWT water comes to the village with a pressure of 3.0 kg/cm2). At the second step up pumping station pump K 20/30 brand (1 pc.) with frequency converter is installed. Installation of frequency converter provides energy saving. SPS number 2 delivers water to the upper part of the village to the three‐stored houses.

3.2.2. Characteristics of the sewage network Sewer network length is about 5.5 km (1 mile ‐ collector Ø 250 mm; 4.5 km ‐ internal networks), a discharge from WTP ‐ 600 m, Ø 250 mm, pipe material: cast iron, ceramics. 176 sewage wells are constructed on the networks. 95% of the networks and their facilities have been built during the 1982‐1989 years. The networks are pretty worn. Below the route of water supply and sewage networks are shown.

Metering of distributed water is organized by metering devices. Own (technology) needs and the volume of leakages is within the limits. The growth of the leakage volume is caused by wear of the distribution pipes. Every year the volume of water intake is growing, for example in 2010 water intake was 34.4 1000 m3 per year, in 2013 ‐ 57,6 1000 m3 per year. Increase of water intake was due to the growth of water sold to the needs of the population (labor inflows to build port facilities) and water use for construction enterprises. Table 11.

3.2.6. Water intake and treatment facilities Water intake and water treatment facilities at Vistino village have been constructed in accordance with typical design project TP №3‐901‐80 in 1987‐1988. Water source is Belaya river that is a small river of the 1st class. River feed is mainly ground‐snow. Flood periods ‐ spring and autumn, although if there are a lot of rains during summer period the water level can go up as well. Taking into account the low water level of the rivet at the water intake, a piled up dam have been constructed with concrete culvert devices.

Figure 6. Dam WTP

Figure 7. Struya‐800

The volume of the water reservoir stable provides water intake treatment facilities "Struya‐800" at any time during the year. Currently water source water is high colored, low turbidity, with low alkaline reserve, high rigidity and pH. High color water of water source, requires a high raw water chemical treatment using a coagulant and soda.

22

3.2.7. Existing water supply and water treatment process

Water from gabion via deepened pipes goes to 2 water intake wells, those are connected to the 1st stage pumping station. Two pumps type ЭК‐9 (К‐45/90) pump raw water from the 1st stage pumping station via pipes 250 mm diameter to с treatment facilities.

Figure 8. 1 stage pumping station

Inside the 1st stage pumping station in 2013 year piping of the pumping equipment was replaced for polyethylene pipes and water metering unit was installed with metering device VSKHN‐150. The accuracy of meter data are doubtful, as usually the metering device to be installed should be about 1‐2 caliber smaller than the diameter of the main pipe. Today the metering device VSKHN‐150 is installed on the polyethylene pipe with diameter of 160mm. The 1st stage pumping station is equipped by workshop for preparation of soda solution that is dosed into the suction pipe of the inlet well. The gap between dosing soda and coagulant is about 2 minutes. Coagulant solution in the required doses, is being dosed into the pressure pipe connector assembly of 2 units before the flocculation chamber. Disinfection reagent ‐ a solution of sodium hypochlorite ‐ is being dosed into the filtered water. Before the flocculation camera there are sieve filters to trap big floating impurities. Treatment facilities “Struya‐800” configured of two typical treatment units “Struya‐400” with total capacity 800 m3 per 24 hours. This treatment unit consists of:

grid filter flocculation chamber, совмещенная с трубчатым отстойником sand pressure filter equipment for coagulation, chlorination and water stabilization.

23

Figure 9. Water intake and treatment facilities, equipment “Struya‐400”

After that water flows into the flocculation chamber where after the coagulant have been dosed flakes of aluminum hydroxide form with the extraction from water of suspended and colloidal particulates. The resulting flakes arrive into the chamber with drums consisting of filled tubes DN 40‐100 mm, arranged at an angle of 60о. Intensive water clarification is achieved by sedimentation of particulates in the tubes of the отстойника. Simultaneously there is a mixing of the part of the sludge in the flocculation chamber. Distilled water with a bit of turbidity is being sent to sand filters for the final cleaning. After that water flows to the treated water tank where pumps of the 2nd stage pump it to the distribution pipe and then to the consumers via main pipeline (length 14 km). Filters are filled with quartz sand of a certain fraction. In accordance with the technical regulations filters are to be washed. As a result of filters washing there are rinsing waters those are to be discharged through coastal discharge, which is a steel pipe DN 250 mm and a length of 100 m located on the right bank of the Belaya river. The discharge is located at a distance of 10 m from the water, the place of discharge is fortified by granite natural stone at a distance of 0.5 m up and downstream of the discharge. Elements of the facilities:

sedimentation: pipes, diameter – 2 m, quantity – 2 pcs. pressure filter: sand, diameter – 2 m, quantity – 2 pcs. sieve filter– 2 pcs.

Dosing of coagulant and hypochlorite is organized by dosing pumps D‐VA‐98‐10, capacity 98 l/h, engine power 0.25 kW. Dosing of soda is used pump D‐VA 135/10, capacity 135 l/h, engine power 0.25 kW. Chlorination. Elektrolitny unit EN‐25, 2 pcs, one is operating and the other one is standing by. The unit consists of: solution tank– 1 pcs, electrolyzer – 1 pcs., operational tank – 1 pcs, rectifier – 1 pcs, dosing pump GND‐25/25 – 1 pcs.

Figure 10. Electrolysis room.

In the 2nd stage pumping station the following pumps are installed: 1. NM 50/20 B/B ‐ 3pcs., (Q=24‐78 m3/h, H=23‐48 m; N=9,2 kW); 2. Wash pump RB‐200, (Q=200 m3/h, H=20m, N=22 kW)

On the territory of the water intake and treatment plant there is a clean water reservoir‐1pcs.,Q‐50m3. The 2nd stage pumping station via cast iron pipe of diameter 350 mm pumps water to Vistino village. On the territory of water intake and treatment plant a diesel generator type A‐01ME is installed that is used when there is no electric power supply. Technological process at the station is controlled by laboratory that is located at the territory of the water intake and treatment plant "Belaya Rechka". Besides monthly water quality monitoring is done by Center of Hygiene and Epidemiology in the Leningrad region in Kingiseppskiy district. Quality of drinking water purification needs improvement. Taking into account the forecast population growth, increase water treatment plants providing capacity with 2 lines. Cleaning quality does not satisfy residents. This is due to outdated equipment and a high degree of wear of water networks.

3.2.8. Proposals for a water purification system

As a purification of water supplied to habitants, a system based on the principles of microfiltration. Estimated composition of water treatment plants:

‐ Block profiteered water. Automatic mechanical filtration with crevice 200. At the heart of the filtering elements of the cartridge is compressed polypropylene discs micro channels are in a compressed state to form a filter element. The advantage of these elements is that the elements are little subject to wear. When pollution wheels pushes the washed, completely restoring their filtering ability.

‐ Chemical dosing unit Node proportional dosing ‐ is designed for input to correct reagent salt in water, to ensure efficiency ultrafiltration system. The metering unit with built‐in pH meter. Is used to adjust the pH.

‐ Block the main water purification from organic substances

25

Ultrafiltration unit. The unit is designed for cleaning water from surface sources from mechanical impurities, suspended solids, organic compounds and bacteria. The principle of operation of the plant: Source water is treated by coagulation and then passes on the ultrafiltration membrane cleaning. Due to the fact that the pore size of ultrafiltration membranes is very small , then the process of coagulation sufficient 30 ‐ 60 seconds of residence time , so the coagulant is dosed directly into the raw water supply pipe in an amount much smaller than in a classical water treatment scheme . Purified water is collected into purified water storage container. Minority (about 5‐15 %) is used for backwashing the membrane, and most of the served user. The choice of this water purification technology a number of reasons, first of all ‐ the poor quality of drinking water in urban areas associated with disabilities of existing treatment facilities. Sandy granular filters that are part of all water treatment plants, are often unable to hold very small particles (colloids) , bacteria and viruses , usually developing in these filters . It is through ultrafiltration membranes can be cleaned with water to European quality standards, because these membranes have a pore size of 0.002 ‐ 0.1 microns, allowing delay bacteria and viruses. Also note the simplicity of installation of such systems, namely, each such conduit system is connected to a source of water, the purified water pipe (for pure water storage tanks), a conduit supplying the washing water from the clean water tanks and the sewer pipe. System storage tanks with the automation system ‐ a prerequisite of ultrafiltration unit, is required to create the volume of purified water for hydraulic and chemical cleaning ultrafiltration unit. The material from which made storage tanks ‐ plastic, making them easier to transport and ensures the longevity of their service life. The system is protected against tanks overflow and automation fill them.

‐ Block secondary water purification from residual organics Rising pumping station based on low noise pumps Grundfos. In this pumping station consists of 3 pumps (2 working and 1 standby). System Automation station pumps work alternately switches , thereby achieving uniform load on pump motors in the station . All pumps are equipped with a frequency converter station, providing soft start equipment and lack of water hammer in the system. Also a complete pumping station includes an accumulator 500 liters. to reduce the number of on / off pump motor and system protection startup pump "dry ." Water enters the system at a continuous carbon filters intended for cleaning water to the residual chlorine, tastes, odors and organic compounds. Loading filter ‐ activated carbon produced from special grades of bituminous coal, characterized by a narrow particle size distribution, has a high activity. Activated carbon is characterized by a selective pore structure, which provides a high degree of absorption and the ability to impregnate. Also, are sufficiently resistant to abrasion, to resist the repeated regeneration. Mode of operation: Water is passed through the column at a time. Process is controlled by an electronic control unit, according to testimony which the controller determines the need for regeneration of a particular column. Controller independently carries regeneration column , this time providing the consumer with purified water from other columns. Regeneration of the filter automatically reverse current of water.

‐ Block water disinfection The metering unit is in automatic mode. If necessary, one can easily change the dose of the reagent.

3.2.9. Waste water treatment facilities Wastewater discharge of Vistino village is organized through sewage treatment plant’s discharge into the Luga Bay of the Gulf of Finland. Sewage network of Vistino village is separate. Civil sewage from the village and recreation via gravity collector of total length 5493 linear meters and diameter 250 mm is going to the intake department of waste water pumping station at Sewage treatment facilities (pipe material: cast iron and ceramics). Start of construction of wastewater treatment plants (WWTP) ‐ 1982 year, commissioning – 1989 year. WWPT of Vistino village are built in accordance with typical design project T‐1646 (contractor: “Engineering equipment” company). WWTP have been built to treat civil sewage and intended for cleaning households. domestic wastewater village Vistino and sewage from fish collective farm “Baltica”. Designing capacity of the WWTP is 1670 m3 per day, fact – 42.8 1000 m3 per year, 118 m3 per day (fact, in 2013 year). Structure of WWTP:

Technological treatment scheme

Wastewater flows into the receiving chamber of the waste water pumping station (capacity 173 m3/h, depth 5.5 meters). For flow measuring of the sewage delivered into the receiving chamber there is a device for proportional discharge. From the receiving chamber sewage is delivered by pumps SM 125‐80‐315/4 (1pc.) and SD 50/56 (2 pcs.) into the aero tank‐clarifier, which consists of two compartments separated by a shield. Dimensions of the tank are 36x6 m (3 pcs). Aero tanks (two compartment) are used for biological wastewater treatment. From aero tanks wastewater go to the secondary clarifiers, where suspended fine particles and activated sludge sediment. In the secondary clarifier (dimensions 36x1,4 m) sludge mixture is sedimenting (runoff + sludge). Biological treatment is performed in the extended aeration mode. Aeration in the aeration tanks is pneumatic. Aerators are perforated pipes. Air is forced by blowers located in the separate building (blowers station). Sedimentation zone is equipped by thin‐layer modules. Return of the circulating sludge in the aeration zone is provided by of airlifts. Air for the airlifts is forced by gas blower 2AF51752 (2pcs.) and 1A24302a (2 pcs.), those are installed in the auxiliary building. From the sedimentation zone water flows by gravity through the steel pipes (diameter 200 mm) to biological ponds (2 pcs.). In biological ponds there is further treatment of biologically treated waste water by oxygen saturation. After biological ponds wastewater flow to disinfection by UV unit with lamps DB 15M and DB 30M. Furthermore wastewater is discharged by gravity collector (DN 250mm, length 600m) through the scattering of channel output into the Luga Bay of the Gulf of Finland. Discharge zone is 140 meters from the water's edge. Runoffs from fish farm “Baltica” (now the farm does not operate) come via separate sewer system into the aeration tanks of the waste water treatment plant. Today the situation at WWTP has worsened due to reduction of runoffs volume and pollution load that was caused by the shutdown of the fish farm and the lack of industrial runoffs as a consequence. Besides all the metal facilities have great physical deterioration. Monitoring of the quality of treatment is done by Center of Hygiene and Epidemiology in the Leningrad region in Kingiseppskiy area. Laboratory tests are performed quarterly. Below you can find the results of laboratory examination of wastewater from WWTP of Vistino village.

Within this territory provision groundwater is uneven, due to the peculiarities of geological structure and hydrological conditions. The source of water may be used groundwater Ordovician aquifer Izhorskogo plateau. Fresh water, bicarbonate, are widely used for water supply in Kingiseppsky, Volosovsky and Lomonosov district of Leningrad region of. Water intake may be placed on sites or Karstolovo Hrevitsa. Also as an option you can consider the construction of a new water intake and structures‐tions of water treatment on the right bank. Luga outside surges waves of intense action and anthropogenic pollution sources (upper stream village. Mezhniki and Kuzemkino). Regulation of water intake must be specified during engineering surveys. In the village. Logs and pos. Old and New Garkolovo not provide centralized water supply. Sources of water supply in these localities can be underground borehole. Comparison of water supply options for investment shows a significant advantage of the organization of a series of water.

Also, are sufficiently resistant to abrasion, to resist the repeated regeneration. Mode of operation: Water is passed through the column at a

time. Process is controlled by an electronic control unit, according to testimony which the controller determines the need for regeneration of a particular column. Controller independently carries regeneration column, this time providing the consumer with purified water from other columns. Regeneration of the filter timer automatically at a specified time reverse current of water.

‐ Block water disinfection Hypochlorite metering unit operates automatically. If necessary, one can easily change the dose of the reagent.

5.2.1. Technical description and basic parameters of the various options

Development of the area municipality "Vistino rural settlement" provides a major reconstruction of sewage system by implementing one of the proposed options. Option 1: Construction of a new main sewer "Valyanitsy ‐ Yugantovo", whose main objective is to provide the best possible reception of sewage from settlements located in close proximity to the A121 highway, including pos. Valyanitsy, Vistino, Ruchi, Dubki, Smenkovo, Krasnaya gorka, Yugantovo. For villages located at some distance from the main sewer (including settlement. Logi, Glinka, Gorki, Zalesye, Pahomovka, Koshkino, Mishino, Slobodka) provides gravity sewer system within the boundaries of the village, and the device CND (sewage pumping station) in the lower part of the network, as well as the construction of pressure sewer network for supplying the main drains on the gathering "Valyanitsy ‐ Yugantovo"

5.2.2. An assessment of the pipe network in need of refurbishment and recommended method of

reconstruction.

Given that the centralized municipal sewage Municipality, MO "Vistino rural settlement" covers only part of the settlements, does not provide the necessary bandwidth, as well as taking into account the high level of deterioration of existing networks and structures, providing a complete replacement of sewer networks and facilities to the new. This solution will fulfill the necessary requirements for the population with housing and communal services, accelerate the development of territory of the municipality, as well as provide a high level of energy efficiency in the industry. According to preliminary data, the volume of construction will be:

township network gravity sewer network D = 160mm ‐ 20 km gravity sewer network D = 200mm ‐ 2.0 km network pressure sewer D = 90mm ‐ 3.6 km

40

main sewer D = 250mm ‐ 7.6 km D = 315mm ‐ 4.0 km D = 400mm ‐ 1.6 km

Release from CBS D = 400mm ‐ 1.0 km Pumping Stations

sewage pumping station 270 m3 / h ‐ 1 pc Sewage treatment plants

CBS 4500 m3/day Similarly, Option 2 Option 1 provides for the construction of the new main gravity collector "Valyanitsy ‐ Yugantovo", whose main objective is to ensure reception of domestic wastewater from settlements of the municipality, in this case, in each village organized pressure sewer system «Presskan». The uniqueness of this system is a device for a group of buildings (1 to 10) fiberglass well equipped pump "1 1/4'' NP ‐ 02", specially designed for this system, which due to their characteristics allows to provide stable operation with parallel connection to single standpipe network. System «Presskan» specially designed for sparsely populated settlements located in a hilly area, far away from the endpoint receiving wastewater. This system eliminates the gravity drainage areas, reduce the cost of network construction deep foundations (over 2 meters), and the installation of manholes on the network. The whole system is combined into a common discharge manifold D = 63‐90mm and is tight. Wastewater treatment and discharge into the Luga Bay Gulf of Finland provided similarly to the first embodiment, through the new wastewater treatment plant. The length of pipe diameters, in need of refurbishment. Whenever possible, the recommended method of reconstruction. According to preliminary data, the volume of construction will be:

township network network pressure sewer D = 50mm ‐ 15 km gravity sewer network D = 160mm ‐ 7.0 km Chap. collector

D = 250mm ‐ 7.6 km D = 315mm ‐ 4.0 km D = 400mm ‐ 1.6 km

Release from CBS D = 400mm ‐ 1.0 km Pumping Stations sewage pumping station 270 m3 / h ‐ 1 pc Sewage treatment plants WWTP 4500 m3/day

5.2.3. Assessment of the risks and impacts of different options. In comparing the two options presented, in terms of the possible risks of environmental impact, it is preferable to the latter, since most of the networks is a sealed system, without the pressure device manhole that allows to prevent sewage in the soil, thereby increasing the current environmental safety area. Also the second option less investment costs, but you must consider the fact that the equipment used in the construction can not be replaced by similar domestic production, which should certainly be taken into consideration when choosing the final version of drainage area municipality "Vistino rural settlement."

7. CONCLUSIONS AND RECOMMENDATIONS

Lack of engineering infrastructure of water treatment and sanitation is a clear limitation for any settlements development, including agriculture. On an example, you can explicitly Vistino trace the relationship between population, development of the industrial zone "Ust‐Luga" and plan infrastructure organizations. Investment options calculations presented in this paper suggest public investment in utility infrastructure and co‐financing of industrial and logistics enterprises. For successful implementation of the plan requires a direct part of administration of rural settlements, and monitor the implementation of the federal government. In technological solutions in water treatment and disposal of scenarios used several different equipment. Different scenarios imply the possibility of choice for tenders and selection of the optimal set of equipment. The practical value of this work is to describe the current algorithm is exhaustive documentation of the pre‐stage. With this document, the administration of rural settlement "Vistino" get a complete picture of network description of repair options, the possibilities of using different types of water treatment equipment and wastewater treatment equipment.
