An estimated 40% of Connecticut residents manage their home wastewater with a septic system. A septic system is an underground wastewater treatment process for homes that are not connected to public water utility services for that treatment. A septic system consists of a house sewer, septic tank, leaching field, and any pumps or siphons needed between those features.
A failing septic system can be an expensive but necessary fix for homeowners. Careful management of wastewater discharge is needed because a failed system can create health hazards inside and outside a home. Including potentially contaminating surface and drinking water with dangerous bacteria and viruses.
Proper septic care and maintenance is important for individuals and for protecting water sources from potential bacteria and virus contamination of surface and drinking water sources.
This includes: filtration; repairs; connecting to public water; over drilling, redrilling, or relocating well on property; pumps or other equipment.
The key is maintaining access to safe drinking water. For many people in the state, ground water is the best and only option for drinking water. CT homes that are serviced by groundwater through private wells have many considerations about maintaining their water source. Private wells are unregulated by the Federal Government, which means there is no Federal oversight on the quality and condition of the well. When private wells need repairs and features to support continued water access for a home, the homeowner is solely responsible for that repair (this is not the case for community wells, or other multi-home water systems).
