ACEC WA Bronze Award for Engineering Excellence | 2012
McMillin Reservoir, Tacoma Water

Tacoma Water needed to cover the last of its existing open air storage reservoirs at its McMillin Reservoir site, and determined that constructing two 33 MG pre-stressed, strand-wrapped concrete reservoirs inside the footprint of the existing Reservoir No. 2 would provide the best solution. Overall construction of the reservoirs is impressive and results in the world’s largest diameter, pre-stressed reservoirs. RH2 was hired in the beginning of 2008 to perform design services and, due to great economies of scale in the design elements, was able to complete engineering for less than 1.5 percent of the overall project cost.
