Basic Septic Tank and System Information
Septic systems treat and disperse relatively small volumes of wastewater from individual and small numbers of homes and commercial buildings. Septic system regulation is usually a state and local responsibility. The EPA provides information to homeowners and assistance to state and local governments to improve the management of septic tanks to prevent failures that could harm human health and water quality.
If properly designed, constructed, and maintained, your septic system can provide long-term, effective treatment of household wastewater. If your septic system isn’t maintained, you might need to replace it, costing you thousands of dollars. A malfunctioning septic tank can contaminate groundwater that might be a source of drinking water. And if you sell your home, your septic system must be in good working order.
