Soil Percolation Testing in El Monte

A soil percolation (perc) test is always required on the land where the septic tank system is going to be built. This test determines the rate in which soil absorbs a known volume of water and will help to ensure that the land (soil) is suitable for a soakaway, and to make sure that the soakaway is designed properly.

Is a Percolation Test Necessary?

A perc test is required by most county health departments to determine whether a property is suitable to hold a septic system. Septic systems are designed in a way that requires a septic drain field or “leach field” to drain away any excess water. When solid waste settles in a septic tank, the excess waste water is then distributed through the septic drain field by way of a network of perforated pipes.

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 perc test involves drilling multiple holes and observing the rate at which water poured in dissipates.

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 El Monte health department before proceeding.
