City of Billings Fox Pump Station
The City of Billings was having problems with a pressure zone near Skyview High School. This zone was experiencing extreme demand fluctuations that were pushing the existing closed loop Fox Pump Station beyond its capacity limits. The station also had no storage and was
unable to meet peak hour demands.
Additionally, the impeller on the smallest pump was deteriorating at a quicker rate than expected due to cavitation.
The city needed to find a solution for the pressure fluctuation issue and implement a system that could maintain adequate pressure during peak demands. Morrison-Maierle was hired to study, model, and evaluate this pumping capacity issue.
The plan prior to the study was to construct a reservoir and expand the pump station. However, the study indicated that it would be better to construct a new closed loop pump station. Furthermore, a water age analysis showed that adding a reservoir now could cause significant water
quality problems during months when demand was significantly less.
Morrison-Maierle designed a new closed loop pump station that includes a
manufacturer-supplied, prebuilt pumping system inside a customized building. The station capacity was designed for future expansion when water demands increase. And, with the updated system, a new reservoir can be added without concerns about water age.
Now, the City of Billings has an improved water distribution system that can meet peak hour needs while increasing flexibility to handle variable water demands. It also saved the cost of building a reservoir now that would have caused operational and water quality issues in the near future.
