City of Upland Prestressed Concrete Tank, Upland, CA

WHB’s operating company Brady was tasked with both strengthening an existing tank as well as designing a new 7.5 MG circular, prestressed concrete tank and pump station improvements.  The City was concerned that their current tank could potentially fail after a similar design in another jurisdiction made headlines in 1998 with a catastrophic failure.  Brady managed the design for temporarily strengthening the original tank by installing steel strands along the exterior upper and lower areas of the tank.  WHB then prepared the plans, specifications, and estimates for a new tank designed in accordance with California Building Code, ASCE 7, AWWA D110.  Brady was responsible for completing both the structural design along with EI&C, mechanical, and water quality.
