Coleman Engineering designed a 3-million-gallon pre-stressed concrete water storage tank together with a non-potable water pump station capable of a firm delivery of 3,300 gpm. The tank elevation was set to correspond to the existing hydraulic grade line of the wastewater treatment plant discharge so that double pumping would be avoided. The tank and pump station were sized to maximize the opportunity to store and deliver NPW so that surface water discharge will be minimized.
