Septic Compass is a free service that connects homeowners with licensed local septic companies. We are not a contractor and do not perform septic work.

The short answer

A new septic system is installed after a perc test confirms the soil can absorb effluent. Installation covers the tank, distribution box, and drain field, sized to the home's bedroom count and permitted by the county health department. Cost varies widely by soil, system type, and site, commonly $5,000–$20,000 or more.
