If you aren't connected to a city sewer system, you probably have an on-site wastewater treatment system--a septic tank & a drainfield. A failed septic system can be a major expense and put the groundwater that supplies your drinking water at risk. The resources on this page will help you learn more about the care of your septic system to prevent unexpected problems.
