How does your septic system actually work? If you live in a rural area which does not have a centralized sewer system, you most likely have a private septic system. Basically nature and technology combines to treat the wastewater from your household plumbing system including bathroom, kitchen, laundry and any other drains your home possesses.
A typical septic system includes a septic tank and a drainfield which can also be referred to as a leach field or soil absorption field.
The wastewater from your home is sent to the septic tank through one main drainage pipe. The septic tank is a buried water-tight container usually made of concrete, fiberglass or polyethylene. It holds the wastewater and allows the solids to settle to the bottom, forming sludge, and the oils and grease float to the top and form scum. Natural organisms in the septic tank will digest the organic matter. The idea is not to let the sludge and scum leave the tank and enter the leachfield. Compartments and a t-shaped outlet help make that happen.
The liquid wastewater, called effluent, leaves the septic tank and enters the leachfield. The leachfield is a shallow, covered excavation created in unsaturated soil. Engineering plans are required for the best placement of the septic tank and leachfield on the property. The pretreated effluent is discharged through piping onto the porous surface of the leachfield and filtered through the soil. The soil treats the wastewater as it percolates through the soil and eventually joins the groundwater. If the drainfield is overloaded with too much wastewater, it could flood, causing the sewage to flow to the surface or backup into the house. The wastewater percolates into the soil, naturally removing coliform bacteria, viruses and nutrients.
Maintenance is a key component to keeping your septic system functioning properly. Pumping your septic tank, generally every 3 years, depending on your household size and habits, is essential.
