Coquitlam LEED water treatment facility  

Operated by Metro Vancouver (MV), the Coquitlam Water Treatment Plant (WTP) provides approximately one third of the total water supply delivered to Metro Vancouver.

To comply with the new requirements under revisions to Health Canada’s Guidelines for Canadian Drinking Water Quality, improvements to the existing Coquitlam water disinfection process were required for rapid and effective inactivation of chlorine-resistant microorganisms such as Giardia and Cryptosporidium.

To address these new requirements, the existing water treatment facilities were upgraded and an ultraviolet (UV) disinfection plant was added.

Ausenco was selected to perform engineering, procurement and construction management services for the implementation phase of the Coquitlam UV Disinfection Project, which strengthened the primary disinfection capability of the gravity-fed unfiltered Coquitlam water supply through the provision of UV disinfection.

Located within the environmentally sensitive Coquitlam watershed, the size and shape of the new facilities were limited by physical constraints of the site.

Working closely with MV, the Ausenco-led team developed the conceptual design for the facility, implementing an innovative vertically-oriented UV design to reduce building footprint, environmental impact, capital costs and long term operating costs. Additional services included assistance with procurement, onsite construction management and lead commissioning services.

The project was completed under the $110 million budget and on schedule, helping MV continue to provide a reliable source of safe, high-quality drinking water to the region while minimising impact on the environment.

Ausenco received the Association of Consulting Engineering Companies of British Columbia, Award of Merit for this project in 2014.

In 2015 the facility was certified LEED® Gold. Leadership in Energy & Environmental Design (LEED) is a green building certification program run by the U.S. Green Building Council. It recognises best-in-class building strategies and practices.
