Nationwide U.S. Septic Network Mon–Sun · 7am–9pm Free Matching Service Email Us

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 percolation (perc) test measures how quickly soil absorbs water, which decides whether — and where — a drain field can go. It is required before a new septic system is installed. The soil evaluation and perc test are arranged through the county health department or a licensed evaluator before a permit is issued.
