On-plot drinking water supplies and health: a systematic review

On-plot water supplies are believed to produce health benefits for household members. However, the scope, magnitude, and relative impact of on-plot water access on waterborne and hygiene-associated diseases is unclear. We conducted a systematic review to investigate the impacts of on-plot water supplies on diarrhea, trachoma, child growth, and water-related diseases. We found that on-plot access resulted in fewer helminth infections, less diarrhea, and greater child height, and that hygiene-associated diseases are more reduced by on-plot water than waterborne diseases. Promoting on-plot water access would improve household water access and deliver benefits to health and well-being.
