ONELIFT RC509 PUMP STATION
Used to Maximize Holding Capacity at University of Arizona $100M Cancer Center
Phoenix, AZ
DESIGN & CONSTRUCTION TEAM
Owner: University of Arizona
Distributor: James Cook & Hobson (JCH), Phoenix, AZ
Design Engineer: Dibble Engineering, Phoenix, Ariz.
University of Arizona $100 million Cancer Center at Dignity Health St. Joseph’s Hospital and Medical Center clinic. As a National Cancer Institute – designated comprehensive cancer center, the six-story, 230,000 sf building provides chemotherapy, infusion, radiation oncology, and diagnostic imaging. St. Joseph’s Hospital and Dignity Health will operate the facility as well as leasing space in it.
THE CHALLENGE
Late placement of electrical utilities prevented the building from using a gravity drain. The shape of the basin was of particular interest because of the extra per foot storage volume. Also, there was very little room to fit the station.
The OneLift pump station was the contractor’s product of choice due to the speed in product delivery and installation, plus it was specified in the bid.
Oldcastle Infrastructure’s OneLift pump station is installed between the building and sidewalk on a very busy street in downtown Phoenix.
The OneLift submersible pump station with integral valve vault was pre-assembled as a complete package, prior to delivery, to ensure the proper fit for concrete and all components. Oldcastle Infrastructure incorporated and pre-installed all equipment in their factory, minimizing re-assembly time and potential problems in the field.
The installation took about 2-1/2 hours and every one was very pleased with the results of this new system. The contractor also mentioned that they saved time and money with the OneLift in lieu of building from scratch.

INNOVATION
Single Structure design
The factory built OneLift pump station offers a monolithically cast valve vault, in what is typically an unused portion of the pump station. This results in a significantly smaller footprint – up to 50% smaller than conventional 2 structure pump stations – allowing it to fit tight sites. The innovative shape and structural design provides ample space for the interior valve vault, while increasing workable system volumes and decreasing the depth of the excavation. The single structure of the OneLift pump station eliminates any potential differential settlement issues, allows for a quick and easy installation by eliminating the typical two-tier excavation of conventional stations, and is proven to be a cost effective method of providing a high quality pump station solution with rapid and reliable delivery. With the OneLift pump station you get fast turnaround time on submittals; which include standard structural and mechanical components.
