How large should lots served by individual wells be for a septic system?

The minimum lot size for individual wells to effectively support a septic system is generally established at one acre. This size allows for the necessary space to accommodate the septic system's drain field, ensuring proper wastewater treatment and preventing contamination of the water supply. Larger lots can provide additional buffer zones that promote effective percolation of effluent into the soil, thereby reducing the risk of system failure and environmental impacts. Adequate space is essential for maintaining distances from property lines, water bodies, and other potential sources of contamination, which is a fundamental principle in on-site sewage facility regulations.
