3 RDCO Drinking Water Annual Report Introduction The purpose of this report is to provide information on the monitoring and maintenance of the Regional District of Central Okanagan s (RDCO) water distribution systems directed by the Interior Health Authority (IH) as set forth by the Drinking Water Protection Act. During 2017 the RDCO continued to monitor and improve the domestic water supply. This document will provide an overview of the distribution system, maintenance performed and water system data results and trending. 2.0 Water Distribution System The RDCO administers eight water systems (two are Fire/Community Halls located in the Falcon Ridge area). These systems vary in size with five of the systems classified as Small and three as Large. This Report will contain information for the large systems only Killiney Beach, Westshore Estates and Sunset Ranch. (Figure 1). The Water Systems administered by the RDCO, the number of users for each system and the assigned EOCP number (Environmental Operators Certification Program) are outlined in Table 1. Figure 1 3

4 RDCO Drinking Water Annual Report 2017 Table 1 RDCO Water Systems Water System EOCP # EOCP Classification # of Customers (approx.) Water Source Meets DWO Killiney Beach 1850 WT Okanagan Lake *no Westshore 1852 WT Okanagan Lake *no Sunset Ranch 678 WD Well yes * Killiney and Westshore water systems meet many of Interior Health s water quality objectives including zero Coliforms, zero E.coli and inactivation of viruses and bacteria. However, both systems are not compliant with regard to having two water treatment processes and inactivation of Cryptosporidium - water users can choose to boil their water rapidly for at least one minute prior to consumption or food preparation. Currently chlorination is the only method used to treat drinking water delivered to Killiney and Westshore customers. 3.0 Regulations and Management The regulations for the management of the water distribution systems and the terms and conditions under which water services may be provided are set out in RDCO Bylaw User fees and asset renewal fees vary according to the number of users and the maintenance required for each particular system. Fees are set under the RDCO Water System Fees & Charges Bylaws No (Appendix 1). 4.0 Testing and Monitoring Program The monitoring program integrates source monitoring as well as the quality in the distribution system. Routine weekly samples were collected at each site throughout the distribution system including raw water sources and results are reported to Interior Health on a monthly basis. RDCO staff also conducts in-house testing including free and total chlorine residual, ph, conductivity, turbidity, iron, manganese and temperature. This data was used as background information to supplement on-line monitoring and also as a checking procedure within the Drinking Water Monitoring program. The RDCO tests each system every 2 years for physical and chemical parameters. Any additional chemical testing done in 2017 is included in (Appendix 2). 4

5 RDCO Drinking Water Annual Report Maintenance and Repairs The RDCO continued to implement an operations and maintenance (O&M) program that includes annual cleaning/disinfection for the reservoirs, annual hydrant inspection and flushing, annual generator service and distribution flushing including valve exercising and dead end flushing. 6.0 Conditions on Permit/ System Improvements 6.1 Killiney Beach conditions on permit for 2017 in compliance: Section 8 Long-Term plans for Systems improvements are in progress to meet DWO Killiney Beach Udell Reservoir site landscape improvements awarded to Su Casa Landscaping and is scheduled for 2018 Water System Main Replacement (November 2016 August 2017) by R-355 Enterprises Limited - this work replaced approximately 3 km of existing water main infrastructure in the upper zone including all of the following areas: Winchester Road, Brant Road, Houghton Road, Keithly Road and Moody Crescent.
