Public Works and Environmental Services Alert:
Low pressure sewer systems use grinder pumps to grind the sewage from your home (much like a garbage disposal in your kitchen) and pump the sewage through small pipes to the Wastewater Collection System. Low pressure systems are sometimes used in areas which cannot be served by gravity pipes.
The grinder pump can handle any wastewater that is normally discharged to the sewer from the kitchen, bathroom or laundry. Some chemicals and materials may cause operating problems or safety hazards.
