Soil Percolation Testing in Redlands

A percolation (perc) test determines the soil’s ability to absorb fluids for the installation of a septic system. The results of a percolation test are required to properly design a septic system. Simply put, percolation testing is a way of observing how quickly a known volume of water dissipates into the subsoil of a drilled hole of known surface area.

Is a Percolation Test Necessary?

While you can certainly check the soil’s ability to absorb fluids yourself, to get a septic permit in California, you need to have a licenced professional complete and certify the test.

In the event that your property fails the perc test, you still have other options. Your West Coast Sanitation contractor can go over these options with you.

How Do Percolation Tests Work?

Traditional septic systems only work if the soil in the leach area is adequately absorptive so that it can readily soak up the liquid flowing into it. A typical perc test consists of digging several holes where a septic tank is proposed to be installed. The soil is then saturated fully with water and left overnight. The time taken for the water to seep away is recorded to determine the best suitable place for your septic tank at your site.

Test results are usually good for two to five years, and in some cases can be renewed. However, with all things perc, rules vary greatly from town to town so don’t make any assumptions. Always check with the Redlands health department before proceeding.
