Metro Vancouver's sewerage board has approved a $35.5-million contract for ground work at the Annacis Island Wastewater Treatment Plant in Delta, and the contract has grown by $1,375,000. The site work prepares the ground for a new trickling filter pump station and two trickling filters.
The increase followed additional site investigations and engineering modelling, which checked whether the existing sewer infrastructure next to the site can handle construction loads.
The overall Stage 5 expansion carries a total estimate of $1,340,400,000 for design and construction. The actual spend was $578,526,824 as of Aug. 31, 2026, and a Metro report says there is enough money left in the budget to cover this award.
The plant is also getting a pilot project. Metro Vancouver issued a request for proposals this summer for a firm to run and maintain the new Annacis Island hydrothermal liquefaction demonstration facility, which will turn wastewater sludge into biocrude rather than biosolids. The region is testing the technology before deciding whether to scale it up for permanent use. A Metro report says the business case looks positive, with lower life-cycle costs than traditional solids management.
The source sheet does not say whether the contract has received final approval, and it does not name the contractor or give a timeline for the next phase. Metro Vancouver has not responded to requests for comment.
