What is a common method to assess how well a septic system is functioning?

The method of conducting a soil percolation test is essential for evaluating the functionality of a septic system. This test assesses the soil's ability to absorb and filter water, which is crucial for the proper treatment and dispersal of effluent from the septic tank.

By measuring how quickly water drains through the soil, you can determine if the soil conditions are suitable for a septic system. If the percolation rate is too fast, effluent may not be adequately treated before it reaches the groundwater. Conversely, a slow percolation rate could indicate that the soil is saturated, leading to potential backups and failures in the system.

Through this test, septic system installers and engineers can make informed decisions regarding system sizing, design, and placement based on the absorption capabilities of the local soil, thus ensuring the system is efficient and compliant with regulations. This assessment is fundamental in preventing environmental contamination and health hazards associated with poorly functioning septic systems.
