What is Pressure Sewer?

Pressure sewer systems are sanitary sewer systems which utilize a network of grinder pumps to transport wastewater through small diameter pipes directly to a collection and treatment system.

A grinder pump is a submersible pump designed to reduce wastewater particulate to a slurry using a grinding mechanism.

Pressure sewer systems can reduce installation costs, increase system flexibility and reduce the overall environmental impact of the system, all of which benefits contractors and end-users. They can be used as a complete turnkey solution or can be easily integrated into an existing collection system with other technologies.
