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 - McMillan 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. 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.
DPPCC treated over 53 million litres of wastewater in 2018. Treated wastewater is discharged into the Strait of Georgia 242 m off shore at a depth of 43 m.
