How far must a sewage tank be located from a public water supply reservoir?

The correct distance of 100 feet from a public water supply reservoir for the location of a sewage tank is based on health and safety regulations aimed at protecting water quality. This distance helps prevent contamination of the water supply from potential leaks or failures in the septic system. Sewage tanks can contain harmful pathogens and contaminants, and maintaining this buffer zone is critical to safeguard drinking water.

This standard reflects concerns over groundwater flow and the possibility of pollutants migrating from sewage tanks into the reservoir, compromising public health. The established distance ensures that any leachate produced by the sewage tank is less likely to reach the water supply, thus securing a safe drinking water source for communities. Understanding and adhering to this regulation is essential for septic system installers and operators, as it not only complies with regulatory guidelines but also promotes public health and environmental safety.
