A percolation test, often shortened to “perc test,” is an evaluation of the soil’s water absorption rate. It is performed to determine the suitability of soil for a septic system. This test measures how quickly water drains through the soil, which is a crucial factor in determining if the ground can effectively filter wastewater. For instance, if a property owner wishes to install a septic system for a new home, a perc test is typically required to ensure the soil meets regulatory standards.
The tests results are important because they directly influence the design and viability of a septic system. Historically, the process has been used to protect groundwater resources and public health by preventing improperly treated wastewater from contaminating water supplies. Understanding the soil’s percolation rate is vital for ensuring the long-term functionality and environmental safety of onsite wastewater treatment.
