Construction firm PCL will design and construct the rehabilitation and expansion of a water treatment facility in San Diego, according to an Aug. 28 news release from the builder. Total project costs are estimated at $600 million. The U.S. Section of the International Boundary and Water Commission awarded the contract to PCL.
After winning the progressive design-build contract on the South Bay International Wastewater Treatment Plant, PCL chose Edmonton, Alberta-based Stantec to lead the design. A Canada-based contractor, PCL has its U.S. headquarters in Denver.
The project will provide SBIWTP with essential rehabilitation of its existing infrastructure and double its treatment capacity to 50 million gallons per day, with a peak hydraulic flow capacity of 75 million gallons per day, according to the builder. The plant will remain in operation throughout design and construction.
The $42.4 million first phase will cover Stantec’s full-scale design for expansion and rehabilitation of the plant, which PCL expects to be completed within 20 months. Following design, PCL anticipates construction will take about five years, according to the company.
“With decades of experience in wastewater construction, we bring a deep understanding of the complexities involved in projects of this scale,” said Ankur Talwar, district manager for PCL’s civil infrastructure division, in the release.
