What is the setback distance from a lateral trench for wells?

The setback distance from a lateral trench for wells is crucial to ensure the protection of groundwater quality. A setback distance of 70 feet helps prevent contamination from materials that may leach from the wastewater system into the groundwater, which is a vital source of drinking water. This distance allows for adequate separation to account for possible failures or inefficiencies in the septic system, as well as natural filtering effects of the soil. Moreover, this regulation is designed to safeguard public health by mitigating the risk of pathogens and pollutants entering the well water supply.

The specified distance is determined by health and safety regulations that aim for sustainable management of water resources. Understanding these setback requirements is essential for ensuring that both septic systems and well water supplies can coexist safely, maintaining the integrity of the water environment while providing necessary sanitation services.
