  2. 2. Community Location<br />
  3. 3. Santa Clara, El Salvador<br />Santa Clara (pop. 3,165) is a rural community within the municipality of San Rafael Oriente (pop. 16,929), in the Eastern region of San Miguel<br />Local Organizations:<br />Associacion de DesarrolloComunitario (ADESCO)<br />AsociacionNacionalpara la Defensa, Desarrollo y Distribucion del Agua a Nivel Rural (ANDAR)<br /> Peace Corps<br />
  4. 4. Background & Objectives<br />Background:<br />The people of Santa Clara suffer many hardships, as the majority live in suboptimal conditions without adequate housing, education, or an improved water source and the community’s residents are burdened with a high incidence of water-related illness.<br /> Households contract local drilling companies to construct raw water wells. Most wells access the same shallow aquifer contaminated by community pit latrines. The contamination of wells has been confirmed through bacteriological testing of samples throughout the community that were positive for excessive levels of fecal coliform bacteria.<br /> High rate of morbidity associated with water-borne pathogens and related illnesses.<br />Desire:<br /> - Clean water for the Santa Clara community: Households 260 (Expandable to 400).<br /> - Current expressed community preference for piped water delivery to each individual household.<br /> - The community has already located a preferred; semi-remote well from which to extract the raw water for their system.<br />
  5. 5. The project has a comprehensive approach to preventing illness by improving water supply and key hygiene behaviors, especially ensuring safe household drinking water and food, proper personal and domestic hygiene, and effective use of sanitation.<br />
