A septic tank is a small sewage treatment system that is often used in rural areas or places without access to a central sewage system. It is a watertight container that is buried and usually made of concrete, fiberglass, or polyethylene.

The tank is designed to hold sewage and wastewater from a home or business and let bacteria break it down.

Septic tanks work by letting the solid parts of sewage sink to the bottom of the tank, where they form a sludge layer.

The liquid part of the sewage, called effluent, is then allowed to flow out of the tank and into a drain field, where bacteria in the soil filter and clean it.

To make sure that septic tanks are working well, they need to be maintained on a regular basis. Usually, this means pumping out the sludge and scum from the tank on a regular basis so it doesn’t overflow.

Follow the maintenance instructions for your septic tank to prevent problems and make sure it is working well.
