The solution when gravity flow cannot be used due to environmental or grade issues.
Allows smaller diameter pipe than gravity flow
Low pressure system
Internal grinder
Complete and ready to install
Pressure Sewer pumping may be the perfect solution where:

The water table is too high to allow proper grade

Sewage must be moved uphill

Terrain is flat preventing proper grade

Excessive cost of piping a long distance
We know pumps inside and out.
