  • Promoters and the InterventionCommunity members consider the issues of hygiene and sanitation to be both household and community matters; consequently, the program has been designed to address these issues on both levels. The promoters have three major functions: 1) hygiene promotion and education; 2) demonstrations/assistance to achieve proper hygiene practices; and 3) evaluating the intervention. Their efforts focus on building necessary knowledge and skills to adopt and maintain proper hygiene practices; they also serve as role models of these practices. In addition, through community-based participatory research methods, the promoters collect data for evaluating the inputs and outcomes of the program. Training of PromotersThe promoters were recruited from Santa Clara based on certain characteristics, such as leadership skills, minimum literacy and educational requirements, permanent residence in Santa Clara, and long-term interest in the program goals. Nineteen applicants applied for the positions and the final candidates were selected by community vote. Thepromoters received an initial 5-day training by the GWU/EWB/Santa Clara team, and receive follow-up trainings from the MOH and PCV on a regular basis. They were trained with skills in the areas of: leadership, communication and hygiene promotion, time management, problem solving, participatory learning, and data collection/instrumentation. A training manual was created and translated by the GWU team, Ms. Putzer and Ms. Jurado (available upon request).
  • 99% HP had visited home 2x in past month50% had participated in activity past mo. 88% receive hygiene info from HPs (p<0.001)Nearly all (96%) of respondents reported being visited by a health promoter at least one in the past month, compared to only 61.9% at baseline, and the number of persons who reported participating in at least one activity in the previous month increased significantly between baseline and follow-up. More respondents reported receiving information about personal/domestic hygiene specifically from health promoters compared to baseline. Respondents were more likely at follow-up than at baseline to indicate that they had received information from promoters on the following hygiene topics: drinking clean water, treating water, preparing foods safely, and disposing trash adequately.

    Santa Clara, El Salvador - Water Distribution & Public Health Project
  • 2. Community Location
  • 3. Santa Clara, El Salvador
    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
    Local Organizations:
    Associacion de DesarrolloComunitario (ADESCO)
    AsociacionNacionalpara la Defensa, Desarrollo y Distribucion del Agua a Nivel Rural (ANDAR)
    Peace Corps
  • 4. Background & Objectives
    Background:
    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.
    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.
    High rate of morbidity associated with water-borne pathogens and related illnesses.
    Desire:
    - Clean water for the Santa Clara community: Households 260 (Expandable to 400).
    - Current expressed community preference for piped water delivery to each individual household.
    - The community has already located a preferred; semi-remote well from which to extract the raw water for their system.
  • 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.
  • 6. Water Collection - Today
    Carry water in large containers
    Use of horsepower to draw buckets from well
    Transport water with wagons
