The purpose of the Project was to improve the health status of 11,000 people living in 22 rural communities located in the western highlands of Guatemala. Specifically, the project was established to reduce diarrheal diseases through the introduction of potable water systems and latrines as well as a health education program and training activities on the maintenance of the water systems. Intensive community participation in all aspects of construction, education and maintenance was a key project strategy. The project was initiated in November, 1991, and was completed in September, 1993.
