1740 Rollins Road & 842 Cowan Road Pump Station Upgrades

City Project Nos. 84820 & 83390

This project will improve and upgrade the pump stations that were originally constructed in the 1950's and have served their useful life. The storm pump stations are vital in preventing flooding in the affected areas. The sewage pump station provides essential service to the Rollins Road commercial/industrial area. 

The work shall consist of site/civil, process mechanical, structural, electrical, and instrumentation and control upgrades to two existing stormwater pump stations and one sanitary sewage pump station. There are two work sites, one at 1740 Rollins Road and the other at 842 Cowan Road.  The nominal stormwater pump station capacities at the Rollins Road and Cowan Road sites are 90,000 GPM and 63,000 GPM respectively. The nominal capacity of the 1740 Rollins Road sewage pump station is approximately 1200 GPM. The stormwater pump stations are equipped with vertical propeller pumps with below-grade discharges and will be replaced with similar pumps, four (4) at each pump station.  The 1740 Rollins Road sewage lift station is equipped with three (3) dry pit pumps and will be converted to a submersible pump lift station equipped with three (3) 1070 GPM pumps. Ancillary work includes replacement of the standby generators and transfer switches at both sites and rehabilitation of the stormwater Discharge Box structure at the 1740 Rollins Road site, and site restoration work.
