About The Project

There are over 20 projects planned as part of the onsite improvements of the Annacis Island Wastewater Treatment Plant. Key improvement projects include new trickling filters, secondary clarifiers, and a co-generation facility to make better use of green energy captured on site. Detailed design of the remaining Phase 2 Final Works is underway with construction anticipated to commence in 2026. A new digester and biosolids dryer have been added to the expansion program.
