Planners, engineers, and municipal managers are given generalized procedures/equations to estimate the amount of pollutants deposited in combined sewer systems during dry weather so they can make intelligent decisions about sewer flushing programs and other combined sewer management controls. The predictive equations relate the total daily mass of accumulated pollutants deposited within a collection system to the physical characteristics of collection systems such as per capita waste rate, service area, total pipe length, average pipe slope, average diameter, and other more complicated parameters that derive from analysis of pipe slope characteristics.
