The minimum and maximum allowable sewer gradients shall be those capable of producing velocities of 2½ and 12 feet per second, respectively, when the sewer is flowing full. A minimum of 2 feet of cover is to be maintained over the top of the pipe. Pipe cover less than the minimum may be used only upon approval of the Plan Commission. Uniform slopes shall be maintained between structures. A final grade shall be set with full consideration of the capacity required, sedimentation problems and other design parameters.
