The Highland-Fernwood Water System is located on the north east shore of St. Mary Lake on the north side of Salt Spring Island and provides drinking water to approximately 321 service connections. CRD Integrated Water Services is responsible for the overall operation of the water system. The design and construction of water system facilities are overseen by the CRD Infrastructure Engineering and Operations Division. The day-to-day operations and maintenance are conducted by a contractor.

Source Water
The Highland-Fernwood Water System obtains its drinking water from St. Mary Lake, a small surface water body that lies within a 650 hectare, uncontrolled watershed near the northern end of Salt Spring Island. While the lake is used for recreational purposes, only electric boat motors are allowed. During the warm months of the year, North Salt Spring Waterworks operates two large aerators in the middle of the lake. These aerators provide oxygen to the bottom layers of the lake.
Water Treatment Process
The Highland-Fernwood system was upgraded in 2012 to include one centralized treatment plant consisting of dissolved air flotation, filtration, disinfection with ultra violet light and chlorine (liquid sodium hypochlorite) disinfection.
Distribution System
Treated water is pumped to the storage tanks within the Highland-Fernwood system and distributed to customers through a network of mostly 100mm (4“) water mains. Service connections are provided to the property line with curb stops and individual household meters. Service from the property line to the dwelling is the homeowners’ responsibility. The distribution system also contains hydrants and standpipes.
