A residential septic system
is an on-site tank and leaching field located on a property that is used for treating all the wastewater from your house – including drainage from your dishwasher, washing machine, toilets, showers, and sinks.
It is the responsibility of the homeowner to maintain, repair, or replace all components of a septic system so that it will protect the environment and public health.
Poorly functioning or failing residential septic systems can be a source of water pollution; they can leak sewage into the stormwater which can be carried into rivers, lakes, and streams.
The Clean Water Campaign offers a Homeowner’s Guide to Septic System Maintenance
, which highlights safety tips and answers frequently asked questions.
