What is the required separating distance from a sewage tank to a groundwater drain located up gradient or on sides?

The required separating distance from a sewage tank to a groundwater drain located up gradient or on the sides is critical to ensure proper functioning of the septic system and to prevent contamination of groundwater sources. A separation distance of 25 feet is established as a standard to minimize environmental impacts and potential health risks associated with sewage systems.

This distance helps to ensure that any effluent from the sewage tank does not infiltrate into the groundwater drain, which can lead to cross-contamination of drinking water supplies. It accounts for factors such as soil absorption, groundwater flow direction, and the potential for system failures that could occur over time.

By maintaining this required distance, regulatory measures aim to protect both public health and the environment, thereby reducing risks related to waterborne diseases and preserving the quality of groundwater resources.
