Sewers with maximum velocities exceeding fifteen (15) f eet per second shall be cradled in not less than four inches of concrete with suitable anc horing on long slopes. Pumps or compressors located in a lift station provide the energy for wastewater conveyance in force mains. 4.4.B Velocity and slope All sanitary sewers shall be designed and constructed to provide a minimum velocity of 2 fps flowing full. 2. The copy of the UPC we have (an old one - 1988) doesn't mention a maximum slope, and neither do any of our other design references. Calculations may be required. Larger diameters may be required to accommodate capacity or to minimize grades. International Conference on Water Management Modeling, 50% and above - Not over 16 feet on center. Not many regulatory authorities specify the minimum slope of a 6" sewer pipe. Slope is useful in draining sewer pipes because is is calculated to provide a minimum cleansing velocity for when the pipe is at a full flow or half flow.
