The Capital Regional District (CRD) supplies water to the City of Victoria and the
surrounding area. Victoria is the provincial capital of British Columbia, Canada, and has a population of over
310,000. Over the past several years, the CRD has been planning upgrades to its
chloramination treatment facilities. The planning stage involved investigating various
filtration and disinfection strategies. Ultimately the CRD adopted a plan incorporating
the use of ultraviolet (UV) disinfection combined with chlorination and chloramination for its water
treatment improvement project.
Between 2002 and 2004, the CRD has implemented the installation of a 580 ML/d UV
disinfection system. The system was retrofitted into the existing water system and
commissioned in March 2004. This paper describes the project, the project
implementation, and some of the challenges that faced the design team, which included: UV transmittance; hydraulics; and, control. Includes 7 references, table, figures.
