The automatic transfer switch (ATS) at the Piney Creek Lift Station (PCLS) recently experienced a failure that revealed underlying issues with the current electrical layout in the facility. These issues include being unable to isolate the lift station power without Xcel’s assistance, being unable to isolate and easily remove either the normal or emergency power breakers for maintenance, and high arc flash ratings on the ATS making it unsafe to service. The lift station is a critical asset in the City’s system that can reach overflow levels in as little as 5 minutes under peak flows. In the event the lift station is inoperable, sewage will spill into Piney Creek which is a Water of the State and eventually discharges to Cherry Creek Reservoir. Aurora staff has installed a band aid fix that allows the emergency generator to run a single pump and has parts on order to return the lift station to its former operating conditions. This project will replace the “band aid” fix with a permanent solution.
The City is planning to construct improvements to improve redundancy, operational efficiency and safety for City employees. The project will install and construct Conduit & Wire, ATS, cabinets, controllers, power monitors, PLC integration, door intrusion switches, motion monitors, and other miscellaneous electrical and civil site improvements necessary to complete the project.
