4 P a g e 3 Introduction Under the terms of the City of Revelstoke s Operating Permit, the City is required to provide an annual report to users of the system that provides an overview of the water system, and a summary of water test results, maintenance and improvements made to the system. All water suppliers are required to provide a similar annual report to their users. This report has been submitted to Interior Health and is posted on the City of Revelstoke website. Revelstoke Water Distribution System The City of Revelstoke has approximately 3023 residential and 312 commercial water connections serving the citizens of Revelstoke. These users primarily get their drinking water from Greeley Creek. The City also utilizes a secondary source from the Golf Course well groundwater field. Water from the Greeley Creek source is treated through a membrane treatment facility. However, under the City s Permit to Operate additional treatment with chlorine is required to ensure the integrity of the water is maintained while it travels through the distribution system. Water from the Golf Course well is treated with chlorine before it enters into the distribution system. As part of the water distribution system the City maintains 98 km of water main, 2 reservoirs and 2 pump stations. Figure 1 shows the layout of the City s water distribution system. Greeley Creek Water Treatment Plant Located approximately 8km from the City of Revelstoke, the Greeley Water Treatment Plant is the primary water treatment facility for the City. The plant was constructed in 2000 and uses a micro filtration membrane system to remove water born parasites and particles. The plant also adds chlorine to the treated water to ensure the integrity of the water up to the user s tap. The plant is capable of supplying up to 175 l/s. At the time of its construction the plant was one of the most advanced facilities in North America and the first of its kind in British Columbia.

6 P a g e 5 Golf Course Well The City of Revelstoke operates a groundwater well and disinfection station located adjacent to the Columbia River on the City of Revelstoke s municipally owned golf course. The well is used as a back-up water supply to the Greeley Creek water source as well as providing additional water to the system during periods of peak demand. Additionally the well provides raw water to the golf course for irrigation purposes. The well is capable of supplying 70 l/s. Disinfection at the site is provided through a sodium hypochlorite injection system. Reservoirs The Trans Canada Highway Reservoir is located off the Trans Canada Highway and the Arrow Heights Reservoir is located above upper Arrow Heights. The Trans Canada Highway Reservoir is a steel tank which holds 4.55 million liters of water. A new tank was constructed in The reservoir is the primary reservoir for the City of Revelstoke. The Arrow Heights Reservoir is a 2.27 million liter concrete tank. The reservoir was constructed in Distribution System The City s 98 km water distribution system is made up of 10.8 km cast iron pipe, 11 km of ductile iron pipe, 3.7 km of galvanized pipe, 37.1 km of asbestos concrete pipe and 35.2 km PVC pipe. Pipe sizes range from 50mm to 300mm in diameter Water Mains Proportion of Material Types 11.1% 35.9% 11.2% 3.8% Cast Iron Ductile Iron Galvanized Asbestos Concrete 37.9% PVC Figure 2 Water mains by material type

7 P a g e 6 The age of the water mains range from new to approximately 82 years old. The age of the pipe does not necessarily reflect the need to replace it as the various material types have different average life expectancies. For example cast iron pipe can last up to 100 years whereas galvanized pipe may only last up to 40 years. The City has an active program to replace pipes that are either inadequately sized, in poor condition or have reached the end of their functional life Water Mains Proportion by Age 2% 15% 59% 24% <25 Years Between 26 to 50 Years >50 Years Unknown Figure 3 City of Revelstoke Water Mains Proportion by Age Pump Stations The Arrow Heights Pump Station is used to fill the Arrow Heights Reservoir. The station was constructed in 2005 at the same time as the Arrow Heights Reservoir. Revelstoke Mountain Resort completed the Revelstoke Mountain Resort Booster Station in 2010 for the City. The station regulates the line pressure to Mackenzie Landing and Monashee Estates at present. In the future, the station will also be used to fill additional storage reservoirs that will need to be constructed as the resort grows. SCADA (Supervisory Control and Data Acquisition) A SCADA computer control system is used by the City to monitor and control the functions of the water treatment plant, pump stations and reservoirs. This system allows the Engineering and Public Works Department to monitor reservoir levels, the on/off status and flows of pumps, and chlorine residuals

8 P a g e 7 within the system. The operator can change set points and monitor the systems remotely 24 hours per day, seven days per week. Alarms are set to alert operators to potential problems within the systems. Pressure Zones The City is divided into 5 pressure zones. The system pressure in each Zone ranges from 40 psi to 130 psi. As part of its Water Regulations Bylaw, the City requires all service connections to the City s water system to have a pressure reducing valve where the service line enters into the premises. Routine Maintenance Program: Distribution Fire hydrants are inspected and flushed annually. Starting in 2011 the City initiated a program to exercise water main valves to make sure that they are operating properly. A valve exerciser has been purchased and is used extensively. Golf Course Well The City carries out a regular preventative maintenance program at the golf course well and disinfection station. The program includes a daily site visit, running the well pump daily to insure that it is at the ready if required as well as insuring the disinfection stations are operating within normal parameters. Greeley Creek Water Treatment Plant As part of the preventative maintenance program for the plant, the site is visited daily and the chlorine disinfection unit is inspected. As part of the routine maintenance of the membrane filtration system, individual filtration units are taken off line after a set volume of water has passed through them. The isolated unit is put through a chemical back wash to clean the filter and then put back on line. Each filter unit must be replaced at least once every 10 years, the City s five year capital plan currently has the next replacement scheduled for Reservoirs The City s reservoirs are inspected regularly to make sure the site and structure are secure. In the case of the Arrow Heights Reservoir the flow through the reservoir is monitored remotely to insure that there is adequate turnover of water within the tank to maintain chlorine residuals. Pump Stations The Arrow Heights and Revelstoke Mountain Resort pump stations are inspected daily. All pumps and motors are inspected and serviced annually as per the operations and maintenance protocols for each facility.

9 P a g e Improvements New System: Replaced the water main on 2 nd St, outside City Hall Existing System Upgrades/Replacements: Replaced 5 fire hydrants, which were upgraded to full hydrant with pumper port Completed upgrades at the Water Treatment Plant Completed water main upgrades at Mutas Loop, near McDonalds Completed water main upgrades on Oscar St in association with the newly constructed affordable housing complex Capital Projects and Improvements In 2016, the City of Revelstoke is planning to undertake the following projects: Replace Illecillewaet River Crossing water main Undertake a water valve replacement program Upgrade Arrow Heights PRV, including installation of a new flow meter and electronic flow control Big Eddy Water System upgrades following authorization from the Inspector of Municipalities to establish a Local Area Service Bylaw and transfer ownership of the system to the City Install Thomas Brook waterline if City boundary extension approved and a Local Area Service Bylaw is in place Continue Fire Hydrant Replacement program Big Eddy Waterworks Drinking water in the Big Eddy neighbourhood is provided by the Big Eddy Water District. In August 2014 the City received a letter from the Big Eddy Water District requesting to discuss potential transferring ownership and responsibility for operations of the Big Eddy Waterworks. The City is working with the Big Eddy Water District to address long term water supply and quality concerns. In 2015 MMM Consulting completed a study which evaluated the infrastructure, management and finances of the Big Eddy Water District. The report recommended a list of required infrastructure upgrades to be completed over a 10 year timeframe.

10 Water Consumption (m 3 ) P a g e 9 In July 2015 the City was successful in receiving $3.5 million in grant money through the Government of Canada s New Building Canada Fund for the Big Eddy Water System project. The grant money will provide 2/3 funding for the recommended infrastructure upgrades. The residents of the Big Eddy, through a petition process in February 2016, met the threshold for the City to proceed with transferring ownership of the water system to the City. The City is currently waiting for authorization from the Inspector of Municipalities to establish a Local Area Service Bylaw and transfer ownership of the system to the City prior to undertaking capital improvements. Water Consumption In 2015, the City treated 2 million cubic meters of water. Provincial drought levels reached their highest level in many regions of British Columbia in Revelstoke also experience dry and warm conditions during the spring months. While water consumption in the winter, summer and fall months remained below the 10 year average, Revelstoke saw increased water consumption during the spring months as seen in Figure 4. Annual peak day and low day flows at Greeley water treatment plant can be seen in Figure ,000 Monthly Water Consumption By Year 300, , ,000 Maximun 10 Year Minimun 10 year 2015 * 150, ,000 Figure 4 Monthly Water Consumption by Year Month

12 P a g e Operational Costs 13% 62% 25% interest Transmission/Distribution Costs Administration Figure 6 Operational costs for the City of Revelstoke in 2015 As the population in the City grows, the cost of supplying and treating our water grows as well. These increases push the City to review infrastructure and plan improvements to offset these costs on an ongoing basis. Water Conservation The City is a member of the Columbia Basin WaterSmart Program. A metering study completed in 2013 recommended the city s water conservation activities focus on water loss management. In 2015 the City replaced the two flow meters at the Trans Canada Highway reservoir. These meters were identified in 2014 to be reading inaccurately. District meters are a key tool to measure water loss in the system and identify where the loss is occurring. A City staff member continues to attend Farmer s market to provide information on water conservation, including education and distribution of hose nozzles and timings and tips to maintain a healthy lawn while being water conscience. The City has watering restrictions in place all year round. In the following year the city is planning to review the current watering restriction and review options for different levels of restrictions based on drought conditions and water supply.

13 P a g e 12 Water Sampling and Testing Bacteriological As required by the Interior Health Authority (IHA), City staff takes weekly samples of the water for bacteriological testing for Total Coliforms and e-coli Bacteria. There are nine different sampling sites used throughout Revelstoke. In addition, water samples are taken from within project areas after any work on infrastructure. See Appendix A for 2015 test results. Full Spectrum Analysis City staff also sends samples from the source water for a full spectrum analysis. Parameters such as alkalinity, metals, ph, turbidity, and hardness are tested. See Appendix B Boil-Water Advisory Event In the early morning of June 5 th, 2015 it was discovered the 16 water intake supply line at the Greeley Water Treatment plant had become disconnected from the clear well. As a result, staff decided to bypass the treatment plant and untreated water entered the water system while repairs were made to ensure fire flows and system pressures were maintained. The City of Revelstoke and Interior Health issued a boil-water advisory and notified the public through media channels and social media The water supply line was repaired by 11:00am on the June 5 th, and crews began flushing the main from Greeley to the City in an attempt to minimize the amount of untreated water in the system. The advisory was lifted in the late afternoon on June 7 th following deliberate flushing and flushing through irrigation and other uses, which removed any remaining untreated water. The City worked closely with Interior Health while the repairs and system flushing were occurring to ensure water quality was restored in a safe and timely manner. This is the first boil water advisory city operations staff are aware of since the Greeley water treatment plant was constructed in This was a good test of City staff response to an emergency and the roles that all levels of staff, council, the media and Interior Health play in managing such an event. Water Quality Complaints The Engineering and Public Works Department received very few complaints in 2015 about water quality. The local Health Authority requires that our water be tested weekly and that minimum chlorine residual be present at all points in the system. In 2015 there were routine test samples taken from 12 different sites throughout the City. Complaints about dirty water are rare though large flow alterations, such as occurring during system flushing or in the event of a water main break, can stir up residues in the pipes. These disruptions are

14 P a g e 13 unavoidable and customers are advised to allow their taps to run (after repairs are complete or main flushing has stopped) until the system clears. Cross Connection Program The City is developing a Cross Connection Control Program to address the potential for the water system to be compromised by high risk service connections which could introduce contaminated water into the City s water system. Cross Connection risks are monitored on new developments, and where necessary appropriate backflow prevention devices are required to protect the City s system in accordance with the Water Regulations Bylaw #1643. Emergency Response Plan The City has an Emergency Response Plan pertaining to the water supply system. The Emergency Response Plan identifies a number of potential emergencies that could occur and provides a systematic approach on how the City will deal with the emergency. A review and updating of the plan began in 2015 and will be completed in the coming year.
