What is the minimum lot size required for a septic tank system served by individual wells?

The minimum lot size required for a septic tank system served by individual wells is one acre. This requirement is established to ensure that there is adequate space for both the septic system and the well, while also allowing for sufficient separation between them to protect water quality. The space helps prevent contamination of the well water from the effluent that the septic system processes. Having a minimum lot size supports proper functioning of the septic system and minimizes health risks associated with improperly managed sewage disposal.

The one-acre requirement strikes a balance between environmental safety, public health, and practical land use, ensuring that homeowners can effectively manage their sewage while preventing potential waterborne diseases. The size of the lot also allows for proper soil absorption and prevents overloading the system, contributing to the longevity and effectiveness of the OSSF system.
