INTRODUCTION
Metro Vancouver (MV) is a public works organization that serves 18 municipalities (over 2 million people) in the greater Vancouver region of British Columbia, Canada. Amongst numerous other functions including waste collection and disposal, one of its primary tasks is to reliably provide clean, potable drinking water (over 1.1 million m3 per day average) to the residents of the cities served through a system of reservoirs, treatment facilities, pump stations and piping networks.
Most of Vancouver’s drinking water supply comes from watersheds in the mountains on the north side of the city (North Vancouver). Three main watersheds collect fresh water in three primary reservoirs. The reservoirs are protected and the water supply has historically been clean, with little need for elaborate treatment facilities. However, issues with turbidity, though not directly affecting potability, led in the 1990’s to the planning of a Filtration Plant to serve the Capilano and Seymour reservoirs (Seymour-Capilano Filtration Project, SCFP).
