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 2016 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 six water distribution systems. These systems vary in size with three 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 2016 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 (RDCO Water Talk Newsletter Fall 2016). 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 2016 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 2016 in compliance: Section 8 Long-Term plans for Systems improvements are in progress to meet DWO 5 Killarney pump and motor replacement Winchester Reservoir cleaned Water System Main Replacement (November ) by R-355 Enterprises Limited - this work is replacing 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.

The Westshore Estates Water System Improvements are being funded in part from an $870,000 Community Works Fund (Gas Tax) contribution. Killiney and Westshore Leak Detection Project was funded through a Grant from OBWB (Okanagan Basin Water Board). 6

7 RDCO Drinking Water Annual Report 2016 News Release November 25, K.L.O. Road Kelowna, B.C. V1W 3Z4 Telephone: (250) Fax: (250) www facebook com/regionaldistrict Multi-Million Dollar Water System Upgrade Underway Crews are about to break ground on a multi-million dollar upgrade to the Killiney Beach water system. As weather allows through next spring, approximately three kilometers of aging water main will be replaced with new pipe along five roads in the upper area of the system which serves more than 280 connections throughout the subdivision along the north area of Westside Road. Residents along Winchester Road will be the first affected as construction takes place weekdays between 7:00 am and 5:00 pm starting November 28 th. They ve been notified by the contractor, who ll also provide advance notice when the project moves to other streets. Information on this and other projects is available at RDCO Chair Gail Given says, This and two additional projects are going ahead thanks to significant financial support from the Federal and Provincial Governments. The new water main along with construction of a replacement reservoir and new control building received $1.9-million from the New Build Canada Fund Small Communities Fund. It would be a huge burden for customers of the system to fund such expensive infrastructure work, without the support of the senior governments. Construction on the Hope Creek reservoir replacement and Winchester control building along with improvements to the Westshore Estates Water System Mountain and Upper Reservoirs is scheduled to start next spring running through the fall of The Westshore project is estimated at $1.3-million with an $870,000 contribution from the Community Works Fund Gas Tax program. When complete, customers on the two water systems will benefit from improved water quality and storage and fire protection while the improvements will help to reduce interruptions during power outages. Given adds, As these are two of our oldest water systems, the significant funds provided for this critical infrastructure is greatly appreciated. The upgrades will ensure the continued effective and efficient operation of these RDCO water systems. Communications Officer Bruce Smith says, With construction projects of this magnitude, residents and motorists in affected areas may experience some minor inconveniences. Please obey flag people and signage that you encounter along roads in the area during construction. Updated information about the projects and construction schedules can be found at regionaldistrict.com/waterprojects. 7
