Septic systems are an effective, long-standing method for collecting, treating, and disposing of wastewaters from rural and surburban homes that do not have access to municipal sewage treatment plants. They collect and treat wastewaters produced in the bathroom, kitchen, and laundry of a home before discharging them into the soil. These systems are used by homeowners in every county in Kentucky.
