How Does a Septic System Work?

Septic systems consist of a septic tank and drainfield, or soil absorption field. A septic tank is a watertight container typically made of concrete, fiberglass, or polyethylene that is found underground. These tanks hold wastewater produced by your home. When your wastewater reaches the septic tank, it remains inside long enough to allow any solids to sink to the bottom forming a sludge, while any scum (oil and grease) floats above forming multiple layers depending on consistency.

Part of the design of a septic tank includes compartments and a T-shaped outlet that prevents any sludge and scum from exiting the septic tank that then leads to a drainfield. Once the sludge and scum separate themselves from the wastewater, effluent (liquid wastewater) then exits the septic tank and travels to a drainfield.

A drainfield is a covered, shallow, excavation made in unsaturated soil. Pretreated wastewater is discharged through piping onto porous surfaces that allow wastewater to filter through the soil. Once accepted, the wastewater is treated and dispersed as it percolates through the soil, discharging to groundwater. The wastewater percolates into the soil, naturally removing any harmful coliform bacteria, viruses, and nutrients.

Guardian Well and Septic is your local well and septic tank inspectors with services helping to encourage the use of safe, clean, healthy water. With an unmaintained septic tank, you face possible risk of using contaminated water. The entire septic system begins with the septic tank. Without a properly functioning septic tank, wastewater will not be separated and treated properly at the drainfield.
