Grit Removal Calculations

Wastewater systems typically average 1 to 15 ft3 of grit per million gallons of flow (sanitary systems, 1 to 4 ft3/MG; combined wastewater systems, 4 to 15 ft3/MG), with higher ranges during storm events. Because grit is generally disposed of in sanitary landfills, operators must keep accurate records of grit removal. Most often, the data are reported as cubic feet of grit removed per million gallons of flow:

Over a given period, the average grit removal rate at a plant (at least a seasonal average) can be determined and used for planning purposes. Typically, grit removal is calculated as cubic yards, because excavation is normally expressed in terms of cubic yards.
