Shippensburg Borough Authority authorized RETTEW to design improvements to the Authority’s existing well site, which was last updated 17 years before. The upgrades were necessary to provide water for increased system demand. The improvements also raised worker and public safety awareness with a conversion from chlorine gas to on-site sodium hypochlorite generation.

The existing site included a 100-horsepower vertical turbine well pump and motor capable of 890 gpm, chlorine gas for disinfection, a fluoride feed, and centrifugal booster pumps.
The project involved the upgrade of the existing well pump to 125 horsepower for higher head conditions, new electrical and control systems, a building expansion to house new booster pumps and pressure reducing valves, replacement of the existing chlorine gas feed system with sodium hypochlorite generation system, fluoride room upgrades, and installation of a new emergency generator. Because of RETTEW’s excellent project management, we completed construction within seven months, including a relocation of the pressure reducing valves from an existing belowground concrete vault into the booster pumping room to allow for easier maintenance and monitoring.
