What is the required distance between a new septic tank and a water well?

The requirement for a minimum distance between a septic tank and a water well is typically set to ensure the safety and quality of the drinking water. A distance of 50 feet is generally mandated because this separation helps prevent the contamination of the well water from effluents and potential pathogens that can leach from the septic system. The distance is based on considerations of groundwater flow, soil absorption capability, and protective measures for drinking water sources.

This requirement is in line with public health guidelines and addresses the risk of waterborne diseases that can arise from sewage contamination. Maintaining this distance provides a buffer zone that minimizes the potential for septic effluent to influence the well water quality. Other distances mentioned may not provide adequate safety to ensure that contaminants from the septic tank do not reach the well.
