What is a pressure sewer and how does it work?
A pressure sewer system consists of lateral sewers which operate under pressure and grinder pumps at each building which pump sanitary waste into the sewers. The sewers are usually 2” to 6” in diameter and are around 6 feet deep. A grinder pump grinds any solids in the waste water, directs the waste water under pressure to the public sewer, and check valves prevent the waste water under pressure from backing up into your home.
