Summary

Trust staff reported the South Canadian wastewater treatment plant (ST 0138) is about 84% complete in dollars ($159M submitted on $190M contract) with phase 1 slated for July 25, 2026; staff highlighted recent electrical loop energization, three emergency generators started, installation of a 60-inch pipe at Headworks, and ongoing process-equipment startup.

City staff told the trust on Jan. 13 that the South Canadian wastewater treatment plant (project ST 0138) has progressed into late-stage construction and testing.

Harrison Dunlap said the engineer on the project is STV (formerly CPNY) and that contractors across heavy construction have advanced the work to a construction cost of about $190,000,000 under the latest change order. He reported that, as of Nov. 30, pay applications submitted totaled approximately $159,000,000 (about 84% of dollar completion and roughly 77% in time).

Recent achievements include energizing the new plant electrical loop, starting three emergency generators, installation of significant process equipment and paving work, and nearing startup activities for major process units. At the Headworks area, Dunlap highlighted a recently installed 60-inch pipeline segment that had been a major pre-bid concern; he praised contractor performance and safety on that installation.

Dunlap outlined next steps over the coming 90 days: additional generator testing, building-by-building startup of major process equipment, initiating the plant's new discharge-permit performance period and completing remaining paving and grading tasks. He said some site paving will wait until later in construction to avoid ripping up new roads during subsequent phases.

What happens next: staff will continue commissioning and startup activities, begin discharge-permit performance monitoring in the coming quarter, and return status updates to the trust.
