Annual Drinking Water Information

Size and number of connections

The system services approximately 293 active connections and 420 parcels in the service area.


The system is located on the west side of Okanagan Lake approximately 6 km north of Fintry, BC, within Central Okanagan West Electoral Area.


The Killiney Beach Water System is sourced from Okanagan Lake.

System Description

The Killiney Beach Water System was constructed in the late 1960’s and is divided into multiple pressure zones including three reservoirs and four 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 but insufficient contact time to provide 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:

Objective Status
Inactivation of viruses Compliant                 
Inactivation of Giardia Partial Compliance
Inactivation of Cryptosporidium Non-Complaint
2 Treatment Processes Non-Compliant
Less than 1 NTU Compliant
Coliforms and E. Coli Compliant

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:

  • Killarney Reservoir – 76 m3 single cell concrete reservoir;
  • Udell Reservoir – 76 m3 and 307 m3 concrete reservoir cells; and
  • Winchester Reservoir – 340 m3 and 585 m3 concrete reservoir cells.

Distribution system

The system includes approximately 14,000 metres of PVC watermain and four pump stations.

Plans for Future Upgrades

UV disinfection and dedicated forcemain from the Lake Pumphouse to Udell Reservoir are planned to improve water quality.


The water system is owned and operated by the RDCO.
