Nanoose Bay Pollution Control Centre

Nanoose Bay Pollution Control Centre


Wastewater from approximately 1,400 residential and commercial users in the Fairwinds area of Nanoose is treated at the Nanoose Bay Pollution Control Centre (NBPCC). Wastewater is gravity fed and pumped to NBPCC from nine pump stations.

The NBPCC uses chemically-enhanced primary treatment to remove up to 70% of biochemical oxygen demand (BOD) and up to 80% Total Suspended Solids (TSS). NBPCC is one of two primary treatment plants remaining in the region. An upgrade to provide secondary treatment is scheduled for 2023. To learn more about how treatment works and the different types of treatment, visit our How Treatment Works page.

Sludge from NBPCC is trucked to the French Creek Pollution Control Centre where it undergoes further treatment to become biosolids. Biosolids, a soil-like material produced during the wastewater treatment process, are used in the RDN's Forest Fertilization Project. To learn more about how biosolids are managed in the RDN, visit our Biosolids Management page.

NBPCC treated over 111 million litres of wastewater in 2020. Treated wastewater is discharged via an outfall into the Strait of Georgia 450 m offshore at a depth of 39 m.
