Vancouver wastewater treatment plant in Canada to receive $550m upgrade

Metro Vancouver in Canada is planning to invest $550m in the Annacis Island Wastewater Treatment Plant to improve its capacity in order to cope with local water supply demands.

The current facility provides secondary treatment for around 175 billion litres of wastewater per year, which is discharged into the Fraser River post-treatment.

Situated in the Delta district municipality in British Columbia, the plant has a capacity to treat wastewater for around one million residents across 14 municipalities.

Metro Vancouver is carrying out stage five of the project for four years, and following completion, the plant will have an increased capacity for an additional 250,000 people, according to journalofcommerce.com.

The project design is said to be almost 60% complete.

The detail design for phase one of the project is likely to be completed by 2018, which will include expansion of the primary tank, secondary clarifiers, solid contact tanks and additional odour facilities at the plant.

JJM Construction/Geopac has already been awarded a contract for the ground improvement (GI) works under the first phase upgrades at the facility.

Metro has also awarded other contracts and tenders for solids contact tanks blowers and has plans to tender the next contract for primary/secondary tanks, odour control and clarifiers, which could be worth $150m-$160m.
