Why test soil before installing a septic system?

Soil testing is important before a septic system is installed. It measures the water absorption rate of the soil, determines the ability of the soil to absorb wastewater and predicts the required size for the leach field. It also analyses the subterranean conditions and the level of water table.

For example, soil with high clay content drains slowly so the wastewater will remain near the soil surface. This can lead to water logging of the area. Testing can also enable property developers to modify the design or make changes to the building structures at early stages of planning. Soil testing in the design phase saves money and time. It also prevents the septic system from breaking down due to poor soil drainage characteristics and save you time and money on expensive repairs in the future.
