El Salvador and Guatemala Urban Environmental Improvement Project

Project Features
In El Salvador, water supply depends mostly on groundwater. Although sewerage collection systems have been provided, these were inadequate and untreated domestic and industrial wastewaters were discharged. Solid wastes from San Salvador were transported to disposal sites, whereas those from Santa Ana were disposed along the national road. Improvement of the existing sewerage systems together with construction of sewage treatment facilities and improvements to on-site sanitation and solid waste management were urgently required to improve environmental conditions. The study for El Salvador involved: an environmental master plan for the improvement of drainage, flood control, sewerage, on-site sanitation and solid waste management facilities for San Salvador, Santa Ana and Sonsonate Provinces with a total design population of 2.2 million in an area of 4,000 sq km; and preliminary engineering for the priority projects identified in the feasibility study.

In Guatemala, the environmental conditions of the urban area in the Rio Samala basin had deteriorated due to the rapid growth of population and industry without provision of adequate infrastructure. Untreated wastewater and solid waste were discharged into the Rio Samala through drainage channels and sewers. The study for Guatemala involved: an environmental plan for the improvement of the drainage, flood control and sewerage systems, on-site sanitation facilities and solid and hazardous waste management in the Rio Samala basin particularly Quezaltenango; an implementation program; and preliminary engineering for the priority projects identified in the feasibility study.

Scope of Services
For the formulation of master plans, NJS reviewed relevant studies and plans; reviewed and evaluated environmental pollution control measures; conducted field surveys; developed alternative sewerage, on-site sanitation, drainage and solid and hazardous waste management plans including cleaner production recommendations for selected industries and evaluated them from technical, social, financial, economic and environmental aspects; and recommended the optimum long-term plans. For the preparation of the feasibility study, NJS undertook additional field surveys; estimated project costs; undertook economic and financial analyses of alternative systems; assessed environmental impacts; evaluated the priority projects; and developed an implementation program for the priority projects; and provided technology transfer to counterpart staff through on-the-job training.
