The Annacis Island Wastewater treatment plant case study

Due to the rapid growth of Metro Vancouver, the Annacis Island WWTP is undergoing an expansion to increase treatment capacity. The project will include the addition of a foul air system that will improve the air quality for the community living and working in proximity of the facility.

About the project

 

The Annacis Island Wastewater treatment plant (WWTP) treats about 175 billion litres of wastewater every year. Located in Delta, BC this plant provides secondary treatment of wastewater for over 1 million residents in 14 municipalities. The treated wastewater is then discharged into the Fraser river.

 

The plant uses anaerobic digestion to break down organic materials from wastewater to produce biosolids and methane gas. The methane gas produced from this process is then used to generate the heat and electricity used to run the plant. The Annacis Island plant produces enough energy to meet 100% of its own heat requirements and about 50% of its electricity requirements. This in turn helps reduce its greenhouse gas emissions by 660 tones every year.

Due to the rapid growth of Metro Vancouver, the Annacis Island WWTP is undergoing an expansion to increase treatment capacity. The project will include the addition of a foul air system that will improve the air quality for the community living and working in proximity of the facility.
