Mosser was hired by ODOT to replace all five pumps, upgrade control panels and create a maintenance access to the underground station. Before the project started, the pumps had a capacity of only 17,000 gallons per minute. Since replaced, the station can now pump 47,000 gallons per minute. That’s the equivalent of filling an Olympic sized swimming pool in only 14 minutes!

Other station updates include a new air monitoring system that ensures the health and well-being of anyone in the pump station, precast access panels and a new sidewalk overtop that is ADA Compliant. The access panels will allow ODOT to service the new pumps without removing the sidewalk as previously necessary.

During the design phase of the project, it was determined that the existing electrical controls were obsolete and had caused the old pumps to deteriorate.  Mosser worked with ODOT to design new electrical controls making them user friendly and more economical to maintain than the previous system. The team is in the final stages of replacing the electrical controls.

Since the beginning of the COVID-19 pandemic, the project team has been adjusting to a new “normal.”  Mandated safety protocols and recommended guidelines are being strictly enforced and adhered to in order to maintain a safe working site.

Remaining work that is nearing completion includes the replacement of electrical controls and running capacity tests during heavy rainfall to ensure the pump station can handle the increased water flow.
