PDZA Seawater Systems Engineering

Location: Tacoma, WA
Client: Metro Parks Tacoma

Working with TJP Engineering, BCRA evaluated the existing seawater supply and distribution systems at Point Defiance Zoo and Aquarium. The team met with City of Tacoma and Department of Ecology to understand the requirements related to the discharge of seawater exhibits at PDZA. This enabled the work on seawater exhibits, including the new aquarium, to move forward. BCRA’s civil and structural engineers analyzed and developed multiple options for replacement or refurbishment of the existing pump station, created a concept plan, investigated phasing, and prepared cost estimates for each option in order to find solutions that met performance and budget goals.

Due to the location of the new onshore pump station, BCRA worked to secure permitting with local, state, and federal agencies.
