Duke Point Pollution Control Centre
Wastewater from 56 connections in the Duke Point service area is treated at the Duke Point Pollution Control Centre (DPPCC). BC Ferries also discharges wastewater at its Duke Point terminals for conveyance to DPPCC. Wastewater is gravity fed and pumped to DPPCC via 3 pump stations: MacMillan Road Pump Station, Cedar Road Pump Station and Duke Point Pump Station.
The DPPCC uses secondary treatment to remove 95% of biochemical oxygen demand (BOD) and total suspended solids (TSS). To learn more about how treatment works and the different types of treatment, visit our How Treatment Works page.
Sludge from DPPCC is trucked to the Greater Nanaimo Pollution Control Centre where it undergoes further treatment to become biosolids, a nutrient-dense humous-like product. DPPCC biosolids are used in the RDN's Forest Fertilization Program. Visit our Biosolids Management page to learn more about biosolids management in the RDN.
DPPCC treated over 56 million litres of wastewater in 2021. Treated wastewater is discharged into the Strait of Georgia 242 m off shore at a depth of 43 m.
