Riverport WWTP - Secondary Treatment Plant in Richmond, British Columbia

Riverport WWTP is a municipal wastewater treatment facility located in Richmond, British Columbia, Canada. It serves a small population of 702 residents within the Metro Vancouver Regional District. The plant is situated in the Fraser Lands area, near the Fraser River delta. The plant provides secondary treatment, which is the standard level required under Canadian federal and provincial regulations for municipal wastewater. Secondary treatment uses biological processes to break down organic matter, significantly reducing pollutants before discharge. The plant treats an average daily flow of 315 cubic meters, reflecting its small service area. The treated effluent is discharged into the Fraser River estuary, a major ecological zone that supports salmon runs, migratory birds, and diverse aquatic life. The estuary drains into the Strait of Georgia and ultimately the Pacific Ocean. As a coastal plant within 10 km of the ocean, Riverport WWTP's discharge must meet stringent environmental standards to protect sensitive marine and estuarine habitats.

Riverport WWTP discharges into the Fraser River estuary, a dynamic ecosystem where freshwater meets the Pacific Ocean via the Strait of Georgia. This estuary is a critical habitat for Pacific salmon, including Chinook and sockeye, and supports one of the largest concentrations of migratory waterfowl on the west coast. The surrounding watershed includes agricultural and urban areas, making nutrient and pathogen control important for downstream water quality.
