This test is a way to measure how well water drains through the soil on a specific piece of land.
This test is essential for determining whether the soil is suitable to support a septic system—an essential requirement for properties not connected to public sewer networks.
Water is poured into test holes during the test, and the soil’s ability to absorb and drain the water over time is recorded.

The results tell you if the site is suitable for septic installation and help identify the type of system that might work best.
Knowing who performs a perc test is key, as this job is typically done by licensed engineers, soil scientists, or environmental specialists with the expertise to ensure accurate results.
Failing a perc test could mean the land is unsuitable for building, significantly affecting its value and usability.
