Subsurface Sewage Disposal Systems
A properly functioning septic system will effectively treat sewage to reduce the risk of groundwater contamination. This is accomplished in several ways: 1) The septic tank separates the solids from the liquids 2) wastewater enters the drain field/leaching system 3) wastewater is evenly disbursed and percolates through the soil. Natural aerobic bacteria in the soil and leaching system effectively remove harmful bacteria, nitrogen, phosphorus, and other contaminants.
Applications
