Annual Drinking Water Information
Large Systems Annual report
Size and number of connections
The system services approximately 279 active connections and 520 parcels in the service area.
The system is located on the west side of Okanagan Lake approximately 10 km north of Fintry, BC, within Central Okanagan West Electoral Area.
The Westshore Estates Water System is sourced from Okanagan Lake.
The Westshore Estates Water System was constructed in the mid 1970’s and is divided into multiple pressure zones including two reservoirs and two pump stations. See Service Area Map for more information. The water system utilizes a Supervisory Control and Data Acquisition (SCADA) system, which allows for remote system monitoring.
The method of treatment is chlorine disinfection. The water system does not currently meet all Canadian Standard Drinking Water Guidelines; however, improvements are planned in the next few years to meet all Interior Health objectives.
The water system currently has sufficient contact time for bacteria and virus inactivation and 3 log inactivation of Giardia to all connections. The following table outlines the water system’s current status of meeting Interior Health’s Drinking Water Objectives:
|Inactivation of viruses
|Inactivation of Giardia
|Inactivation of Cryptosporidium
|2 Treatment Processes
|Less than 1 NTU
|Coliforms and E. Coli
Water Quality Advisories are occasionally issued during high turbidity events, sometimes caused by spring freshet or other disturbances in the source water.
The water system includes the following reservoirs:
- Mountain Reservoir – 510 m3 dual cell concrete reservoir; and
- Upper Reservoir – 1,100 m3 dualcell concrete reservoir.
The system includes approximately 14,000 metres of watermain and two pump stations.
Plans for Future Upgrades
UV disinfection is planned to improve water quality.
The water system is owned and operated by the RDCO.
