Grinder and STEP Systems are low pressure sewer systems. They consist of a control panel, pump, holding tank, and a small diameter pressurized pipe called a force main. These components are located on your property. Wastewater from your home is collected, stored, and then pumped through the force main into the City’s wastewater system.
These systems will not work if there is a power outage. The pump will not be able to empty the holding tank. Using bath and kitchen facilities during these periods may result in a sewage backup onto your property.
