Obtaining Filtration Exemption/Deferral in BC

Description:As with many surface water sources in British Columbia, the Abbotsford Mission Water and Sewer Commission's (AMWSC) Cannell Lake water source requires additional treatment in order to comply with Canadian drinking water standards. Believing Cannell Lake to be a good candidate for filtration exemption, the AMWSC, with the support of Hatch Mott MacDonald (HMM), submitted an application to Fraser Health. Anticipating the approval of the AMWSC's application, HMM developed a Conceptual Design to add UV disinfection to augment the existing chlorination disinfection system at Cannell Lake and meet the Health Canada filtration exemption requirements. Fraser Health granted the AMWSC filtration exemption and approved the installation of a UV disinfection facility for Cannell Lake. This successful application for filtration exemption will potentially save the AMWSC approximately $15M CAD, 75% of the expected capital cost of treatment upgrades.
