In Spring, 1986 the Water and Sanitation for Health (WASH) Project conducted a 3-week operations and maintenance (O&M) workshop on rural potable water systems for Bolivia's Department of Environmental Sanitation (DSA). The workshop, which proved highly satisfactory, provided 21 rural sanitation technicians with practical training in defining O&M problems and setting up O&M procedures in community systems. It also helped launch a new pilot program in O&M systems in two DSA departments. It is recommended that USAID/B continue to support development of O&M systems for DSA and provide commodities for the pilot O&M program and detailed work planning for O&M in pilot areas. Within the next several months, USAID/B should strongly consider the feasibility of a follow-on O&M and institutional strengthening project to sustain the investment made in constructed systems. The current project could be strengthened considerably by offering team building and management and supervisory training for all DSA managerial staff. (Author abstract, modified).
