What is the minimum lot size in acres for a septic system served by a public water supply?

The minimum lot size of one half acre for a septic system served by a public water supply is significant for several reasons. Regulation ensures that there is adequate space for the proper function of the on-site sewage facility and to prevent contamination of the water supply. A half-acre allows not only for the septic system's installation but also accommodates necessary setbacks from property lines, wells, and surface water bodies, which are crucial for the protection of both public health and the local environment.

Furthermore, a larger lot size reduces the risk of overloading the septic system and minimizes the potential for groundwater contamination, especially in areas with high-density development. The half-acre standard strikes a balance between effective waste management and the practicality of residential development, ensuring systems are sustainable and protective of the resources involved. Understanding this requirement is key to ensuring compliance with TCEQ regulations and maintaining safe and healthy living conditions in areas serviced by public water systems.
