Every time you shower, wash dishes or flush a toilet, wastewater containing solid materials and bacteria flows through your home plumbing into a septic tank. A septic tank is an underground, buried wastewater treatment structure commonly used in suburban and rural areas not served by a central sewer system. It uses a combination of natural processes and simple technology to treat household wastewater from bathrooms, kitchen drains and laundry.

Wastewater goes into the septic tank where solid material settles and begins to decompose thanks to anaerobic bacteria that live in oxygen-free environments like septic tanks. Heavy solids sink to the bottom and form a sludge layer. Grease and lighter materials float to the top as a scum layer. A middle layer of partially treated water called effluent flows out of the tank and through a distribution box and perforated pipes that are buried in a gravel-filled field or absorption area, also known as a drainfield.

As the wastewater percolates through the layer of gravel and soil, aerobic bacteria and other microorganisms further break down contaminants – including pathogens, organic matter and nutrients such as phosphorus and nitrogen – into natural byproducts that are harmless to ecosystems. This process lowers concentrations of these substances to the point where they can safely seep into groundwater, ditches or watercourses.

It is very important for homeowners to understand how a septic system works and what they can do to help keep it working properly. For example, do not park or drive vehicles or equipment over a septic tank, distribution box or leach field as this can damage the system components. Also, don’t plant shrubs or trees over a septic tank or the drainage field because they may grow roots that can infiltrate and clog pipes.
