What is a septic tank and how does it work?

A septic tank is an underground, watertight container that receives wastewater from a home's plumbing system. Inside the tank, solids settle to the bottom as sludge, and lighter materials like grease float to the top as scum. Bacteria in the tank partially decompose the waste. The liquid effluent then flows out to a drain field for further treatment in the soil. It's a vital part of an on-site wastewater treatment system. We can help you find experts.
