Pritchard, Sunnyside and West Kelowna Estates Systems
The valley's largest lake, Okanagan, is the source of water for the Pritchard, Sunnyside and West Kelowna Estates Systems.
Each of the three systems has independent, unfiltered intakes, with chlorination and water quality monitoring systems. Each has its own distribution system.
The Pritchard System, which was once also called Shamboolard, is located between Gellatly and Green Bays. This water system serves residential customers on Pritchard Drive and Camano, Milford and Newport Roads. With only 150 connections, Pritchard is the smallest of West Kelowna's water service areas.
The Sunnyside Service Area was established in the late 1960s. The system has approximately 1,000 customers, mostly residential. Over the years the Sunnyside Service Area has expanded to include:
Sunnyside Subdivision in the 70s and 80s
Mission Hill subdivision in the 1990s
Vineyard Estates and Green Bay subdivisions in the 2000s
West Kelowna Estates System
The West Kelowna Estates system has approximately 1,000 residential connections. Water is drawn in through the Okanagan Lake and Blackwood Pump Stations and then distributed via a network of pipes, booster stations and the Blackwood and MacPhail Reservoirs.
The three systems were governed by the Regional District of Central Okanagan prior to City of West Kelowna incorporation in 2007.
Under the Letters Patent, which set out the terms for the city's incorporation, the Pritchard, Sunnyside and West Kelowna Estates systems were transferred over to the new municipality from the regional district immediately after incorporation.
