Creston Wastewater Treatment Plant | Serving Creston, British Columbia

The Creston Wastewater Treatment Plant is located on Davis Road in Creston, British Columbia, within the Regional District of Central Kootenay. The plant serves a population of about 6,654 people, making it a small-to-medium agglomeration under Canadian wastewater management standards. As an operational facility in Canada, the plant is subject to federal and provincial regulations, including the Canadian Environmental Protection Act and British Columbia's Municipal Wastewater Regulation. For a community of this size, secondary treatment is typically required to meet effluent quality standards before discharge. The plant's treated effluent is discharged into the local watershed, which ultimately drains into the Kootenay River system. This river flows south into the United States, joining the Columbia River, which empties into the Pacific Ocean. The plant plays a key role in protecting the water quality of the Kootenay River and downstream ecosystems.

The plant discharges into the Kootenay River basin, a major tributary of the Columbia River. The Kootenay River supports diverse aquatic life, including several species of salmon and trout. Downstream, the Columbia River estuary is a critical habitat for migratory fish and birds. Protecting water quality in this transboundary watershed is essential for both Canadian and US ecosystems.
