What are effluent and sewage pumps used for?

Sewage pumps are used to transport contaminated water to a treatment location when gravity pipework systems cannot achieve sufficient fall. Sewage may often have solids present, so pumps are often fitted with macerators to cut up solids before they pass through.

What's the difference between an effluent pump and a sewage pump?

Effluent pumps are required when you're pumping water likely to contain solids up to 20mm in diameter, such as in mound-type septic systems, elevated septic system drain fields, laundry discharge, trade waste and sump or grey water removal.

A sewage pump system is used for pumping sewage containing soft solids up to 50mm in diameter. Both types of pump operate on a centrifugal basis, with a motor causing an impeller to rotate and create pressure which pushes water into the discharge pipe. However, sewage pump stations tend to use cutter and grinder pumps (known as macerator pumps), while effluent or septic overflow pump stations utilise vortex or channel pumps. On occasion, effluent systems do use macerator pumps in case a solid makes it into the pump station.

Effluent and sewage pumps are suitable for both residential and commercial applications. They can be used as a waste pumping solution in industrial, CWMS schemes and commercial trade waste and raw sewerage contexts.
