Septic Systems
A septic system is a highly efficient, self-contained, underground wastewater treatment system. Because septic systems treat and dispose of household wastewater onsite, they are often more economical than centralized sewer systems in rural areas.

Septic systems are simple in design, which make them generally less expensive to install and maintain. By using natural processes to treat the wastewater onsite, usually in a homeowner's backyard, septic systems don't require the installation of miles of sewer lines, making them less disruptive to the environment.
Septic systems consist of two main parts, including the septic tank and the drain field. The septic tank is a watertight box, usually made of concrete or fiberglass, with an inlet and outlet pipe. Wastewater flows from the home to the septic tank through the sewer where the wastewater naturally separates
solids from liquids over time. Greases and oils float to the top and form a layer of scum while solids settle at the bottom of the tank to form a layer of sludge. This process causes a layer of partially clarified wastewater to develop in the middle.
Waste Separation and Drainage
The layers of sludge and scum remain in the septic tank where bacteria found naturally in the wastewater work to break down the solids in the septic system. Any waste that cannot be broken down is left behind and remains until the tank is pumped. The layer of clarified liquid in the center flows from the septic tank to the drain field or to a distribution device, which helps to uniformly distribute the wastewater in the drain field.
A standard drain field, also known as a leach field, disposal field, or a soil absorption system, is a series of trenches or a bed lined with gravel or course sand and buried one to three feet below the surface. The drain field treats the wastewater by allowing it to slowly trickle from the pipes out into the gravel and down through the soil, using the ground as a biological filter.
