Choosing to use a septic system allows homeowners to manage their own waste disposal, which can be particularly beneficial in areas where public utility infrastructure is underdeveloped or where there's a desire for a more self-sufficient lifestyle. This independence can also encourage more careful management and maintenance of wastewater systems to ensure they function effectively without external oversight.

For instance, while lower installation costs may sometimes be true, this can vary widely based on location and circumstances. Similarly, while maintenance is required for septic systems, they often require less frequent maintenance, but they still demand regular inspections. Improved local water supplies may be an indirect benefit if septic systems are maintained properly, but it is
