Northwest Langley Wastewater Treatment Plant Expansion

The current plant was constructed as a secondary treatment facility in 1978, providing services to approximately 30,000 people in northwest Langley. The new plant will be able to service approximately 230,000 people by 2026, including residents and businesses in Maple Ridge and Pitt Meadows, while providing tertiary treatment.

Significant ground improvements will be undertaken to ensure operation after an earthquake and the entire site will be raised above the 1-in-200-year flood level.
