In most localities, storm water pumping stations only operate for a relatively short period of time during a year. This means that a substantial capital investment must sit idle for long periods of time. Therefore, the design and operation of storm water pumping stations provides a most promising opportunity for cost reduction. Potential savings are even more promising in areas where storms are less frequent. Initial costs can be reduced by providing storage to reduce the peak pumping rate. This will produce savings in the cost of the pump, pump motor, and instrumentation; additional savings can be achieved by reducing the size of piping and valves. Substantial savings can occur if the number of pumps is reduced. These savings will be offset by the cost of providing storage; however, in many cases, a net savings will occur if the storage can be provided at a low cost.
