I-10/Santan Freeway System Interchange Pump Station

Chandler, AZ

Structural

Premier prepared the plans, specifications and estimates package for the storm drain pump station in the southwest quadrant of the I-10/Santan Freeway traffic interchange. The four-level reinforced concrete structure consists of three underground levels extending 58 feet deep and a masonry building at ground level. The pump station was designed to accommodate three natural gas pumps with direct drive engines, one submersible electrically operated pump and a discharge box configured to include a splitter weir. Studies were performed to analyze the hydraulic operation of the station and optimize the pump and storage pipe design.

Premier was also responsible for the interchange ramp design (Ramp NW) and the off-site drainage design, including hydrologic analyses, as well as storm drain and channel design.
