How does a 1000 gallon septic tank work?
An average size is approximately 1000 gallons to 1500 gallons in capacity. Most septic tanks have one or two compartments. The inlet baffle forces the wastewater from the sewer line down into the tank instead of across the surface of the tank and into the outlet pipe leading to the absorption area.

Are septic tanks plastic?
Plastic septic tanks are watertight and are immune to water-based corrosion. They are also rust-resistant. Plastic tanks are less prone to cracking since plastic is flexible, and thus a plastic septic tank does not crack as much as a cement septic tank. Plastic septic tanks are more hygienic than cement tanks.
Do septic tanks have pumps?
Waste and sewage is removed from a septic tank into the drain field either through gravity or with the help of a septic system lift pump. Pumps are usually necessary for septic tanks that sit lower than the drain field and gravity is unable to carry and/or push the effluent out of the tank.
