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.
A new conventional septic system usually costs $5,000 to $12,000 installed. Mound and engineered systems run $10,000 to $25,000 or more because they need extra components and labor. Soil conditions, the perc test result, system type, and permit fees all move the final number.
