How Engineers View the Sanitary Infrastructure

47% Almendares-Vento Watershed– Almendares River (25 mi. long, shallow, contaminated)

– Vento Aquifer - located directly beneath the Almendares River

Source Water: Havana

Olivares-Rieumont et al. 2005

ALMENDARES RIVER

VENTO AQUIFER

COD = 32 to 291 mg/LEF >10, Pb, Cu, Cd, Zn

Water Treatment

Source water quality - poor

Treatment limited– Facilities for producing chlorine no

longer operational according to International Development Research Centre

– Chlorine metering systems in need of repair/replacement

Population self treating water– Boiling – Chlorine tablets

Potable Water Distribution Overall Cuba (PAHO 2000)

– 72% household connection– 21% easy access– 7% without access

Havana: Estimated hours of service per day (Cereijo ed. 1992) – 15% in good working condition– 70% provide water 2 to 4 hours per day– 15% carry water from collection tanks

Needs: repair leaks, replace valves, metering, back up power, surge surpressors on pumps, maintenance for chlorination systems (Alonso Hernandez)

Privatization in Havana and Varadero

($8M investment by AgBar, finanzas.com) 330 million m3/yr pumped (finanzas.com)

potential revenue of $300 M/yr

Wastewater Collection

38%, sewage collection 56%, latrines (Belt and Velazquez 2007)

Havana: Sewage collection system in disrepair (bulk over 80 years old) Cereijo ed. 1992

– 1913 designed for about 600,000 users– 1950s it serviced 1,000,000 million

(Scarpaci et al. 2002)

$30 Billion needed to renovate Havana’s sewer system (Chicago Tribune 2007)

1946, Sewer ConstructionU.Miami Photo Archive

Wastewater Treatment Estimate that 4% of wastewater

collected is treated (Wikipedia)

Havana: (Alonso Hernandez)

– Sedimentation Plant (Outfall to Playa El Chivo, population served = 950,000) Outfall in need of repair

– Biological Treatment Plant (Maria del Carmen, population served = 22,000) not operational untreated sewage to a tributary of the Almendares River

– 3 Other Collection Networks (population served 200,000), No treatment and problems with sewage pump stations

Effluent Disposal

Havana: Disposal to – Luyano: untreated sewage, oil refinery

waste, gas plant waste– Havana Bay: 4 slaughter houses, paint

plant, 2 thermal power plants, food processing factories

– Almendares: Raw sewage and industries near river

New wastewater treatment plant on Luyano River – – $24 Million to treat population of 62,000: ($20 Million from Cuba government, $4

Million from international partners, UNDP-GEF)

INSTITUTIONAL TRANSITION LESSONS LEARNED FROM OTHER COUNTRIES

Eastern Europe Transition:“Critical success factors” and relationship between tariffs and fluctuating affordability.(Infrastructure Department, Europe and Central Asia, World Bank, 2006)

Latin America:•Reform of politicized mode, regulatory agency for tariffs and quality, geographic regionalization of service.(Vivien Foster, Water Supply and Sanitation Board, World Bank, 2005)

•Analysis of departure of international operators, role of local operators, de-privatization trends.(Environmental Division, Inter-American Development Bank, 2007)

Puerto Rico:Integrated water resources (population/ecology balance), de-privatization, tariffs, geographic regions.(PR Department of Natural Resources, PR Aqueduct and Sewer Authority, various dates)
