The CRD is the bulk (wholesale) water supplier for Greater Victoria. The Regional Water Supply System provides drinking water to approximately 370,000 customer across the region through municipal or CRD water distribution systems.

The Regional Water Supply Service was established as a CRD service in 1997 and is administered by the Regional Water Supply Commission, which is made up of elected representatives from the member municipalities in the region.

Source Water

Water for the Regional Water Supply System is currently provided from the Sooke, Goldstream and Council watersheds. Together these watersheds comprise 10,921 hectares (26,985 acres). Approximately 98% of the land that drains directly (catchment area) into the Sooke and Goldstream water supply reservoirs is owned and managed by the CRD.

Sooke Lake Reservoir is the primary source water reservoir within the Greater Victoria Water Supply Area. Sooke Lake Reservoir has a total volume of 160.32 million cubic metres (35.3 billion gallons), of which 92.7 million cubic metres (20.4 billion gallons) are useable for water supply. The reservoir provides about 90% of the total water storage in the supply system.

The Goldstream Water Supply Area, consisting of four surface water reservoirs, is the secondary water supply source for the Regional Water Supply System. The catchment area for the Goldstream Water Supply Area is 2,109 hectares. The combined storage capacity of the four reservoirs is approximately 10 million cubic metres (or approximately two months of water supply for the Greater Victoria area depending on time of year).

The future water supply area, known as the Leech Water Supply Area, will be available in the coming decades to supplement water flow into the Sooke Lake Reservoir. The Leech Water Supply Area includes 9,628 hectares of land. Read more >>

Water Treatment Process

Greater Victoria drinking water is disinfected using a treatment process which consists of primary disinfection (addition of ultraviolet light and free chlorine) of the raw source water entering the disinfection facility, and secondary disinfection (addition of ammonia to produce chloramines) that provides a disinfectant residual in the transmission and distribution systems. The disinfection treatment process provides protection against biological contaminants, including bacteria, viruses and parasites.

The primary water disinfection facilities are located at Japan Gulch at the south eastern tip of the Water Supply Area.

Transmission System

The key components of the water transmission infrastructure include the Sooke and Goldstream reservoirs and dams, the 8 km long Kapoor Tunnel, 110km of transmission pipelines ranging in size from 450mm to 1,525mm in diameter, two water disinfection plants as well as several pressure reducing stations, metering stations and concrete storage reservoirs.

Water flows by gravity in the transmission system from the higher elevation source reservoirs to the lower elevation bulk water supply points. Read more >>
