Ethiopia - Water Supply and Sanitation Project : environmental assessment (English)

This is an environmental assessment of the Water Supply and Sanitation Project for Ethiopia, which increases access to sustainable water supply and sanitation services. Among the potential environmental and social impacts of pastoral water supply systems the report identifies the following: water-borne diseases (malaria and skin diseases) caused by standing water and lack of drainage in area around the well; potential bacteriological contamination downstream (if a watercourse has been dammed),; potential for increased animal concentration resulting in overgrazing and ecosystem degradation; potential for social conflicts between traditional users and settlers and pastoralist newcomers; groundwater contamination; community dependency on a more sophisticated system requiring maintenance, organization, and finance; and possibly reduced access to poor users who may not be able to afford fees. Among the expected negative environmental and social impacts of urban water supply systems are: reduced water flow, potential for conflict among water users, risks caused by works in the water bed and the improper disposal of used reagents, siltation in the reservoir, modifications to the riverbanks, lowering of water table, increase in water costs, and land use for pipelines, water works, and public taps. Impacts concerning sanitation systems may result from shallow water table, improper sludge removal, effluent discharge, and costs connected with collection, treatment, and disposal of wastewater and sewerage. Mitigations will comprise: Proper siting of water wells and distribution points, drainage systems, use of biodegradable drilling fluids and mud additives, construction of properly designed and water tight well heads and proper sealing of pump to well heads, disinfections of pumps and well equipment, chlorination of the well, extraction of well waste material and recontouring--if needed, recycling or disposal of drilling mud, removal of topsoil and reused on site, changes to catchment location or design, identification of and consultation with downstream users, assessment of impact of increased livestock concentration on grass resources, limitation of works in river bed, changes in project siting, phasing of project according to flow fluctuations, storage and disposal of used reagents, avoidance of latrines where water table is shallow, usage of sludge as fertilizer, and awareness promotion of new systems.
