How far should latrines and showers be placed from water sources?

• A. At least 100 feet from water sources.
• B. 300 feet from water sources.
• C. 10 feet from water sources.
• D. Directly adjacent to water sources.

Answer: (A)

Protecting water quality by keeping sanitation facilities distant from water sources is key. Fecal waste from latrines can reach drinking water through groundwater flow or surface runoff, and water used for showers can contribute contaminants to the surrounding environment that may eventually affect the water source. A minimum setback of about 30 meters (roughly 100 feet) is a commonly used standard because it provides a practical buffer that reduces the chance of pathogens reaching wells, springs, or other intakes. This distance helps account for factors like soil type, groundwater depth, and rainfall, which influence how quickly contaminants can move. Distances shorter than that increase contamination risk, while much longer distances, though safer, may not be feasible in all locations. So, placing latrines and showers at least 100 feet from water sources is the recommended practice.
