The wastewater treatment plant is regulated through an operating certificate issued by the BC Ministry of Environment. The treated wastewater that is discharged from the plant is required to meet standards for biochemical oxygen demand and total suspended solids, which each must not exceed 45 mg/L. On most days, the plant’s effluent contains less than 15 mg/L for biochemical oxygen demand and 15 mg/L for total suspended solids.
Recovering Resources from Wastewater
The plant uses anaerobic digestion to break down organic materials from wastewater to produce bio-solids and methane gas. The methane from this process is then used to generate heat and electricity that is 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 reduces its greenhouse gas emissions by 660 tonnes every year.
