Prologis Park – UPS Center Sewer Lift Station
Romtec Utilities engineered, manufactured, and supplied two wastewater lift stations for a new UPS building in Fife, Washington. Both lift station designs are nearly identical and include Ebara submersible pumps in duplex configurations to handle the flow and for redundancy. The only difference is that one uses 3 hp pumps and the other uses 2 hp pumps. Inside the wet well, inlet lines are equipped with drop bowls and one pump station has two invert-in lines. The system electrical controls comprise alternator relays installed inside a NEMA 4 steel painted enclosure for a simple logic controller. Both systems use mechanical floats for in-well liquid level sensing.

Why They Chose Romtec Utilities
JR Hayes, a contractor with the developer, contacted Romtec Utilities for the design and supply of these two lift stations. This is one of many large commercial developments from the developer, Prologis, for UPS. As we began working on this project, it was specified that the concrete wet wells had already been purchased, which is atypical to precede a design. However, using production drawings and site data collected from Barghausen Consulting Engineers, we were able to design the two lift stations to work effectively and incorporate the purchased concrete. Once the designs were completed, JR Hayes purchased both systems directly from Romtec Utilities. During the installation, Romtec Utilities sent an on-site technician to advise during the construction of the lift station and commission the system.
