The Seymour-Capilano Water Treatment Facility is one of the world's largest UV disinfection facilities. It can filter 2 billion litres of water per day, and supplies 75 percent of Greater Vancouver’s clean, pure, drinking water.
Construction of the complex spanned 3 years commencing with forming and placement of 37,000 m3 of concrete and the erection of 900 tonnes of structural steel for the following structures; inlet blending, 12 flocculation cells, 48 filter cells, equipment galleries, an operations and maintenance complex, backwash equalization and treatment facilities, and a residuals handling facility.
The work also involved installation of an additional $35 million of owner purchased equipment including; 24 flocculators, 48 filter underdrain systems, 24 UV reactors, switchgear, MCCs, transformers, generators, belt filter presses, blowers, sludge collection equipment, etc. Piping systems for the project include carbon steel up to 132 inches in diameter.
The project also involved construction of a post treatment facility containing lime silos and dosing equipment for a 200,000 m3 clearwell reservoir.
