7 Executive Summary The District of Invermere is located in the Columbia Valley in Southeastern British Columbia. It is an incorporated municipality that owns and operates a water treatment facility in the area, and is therefore required to provide an Annual Report to its consumers and to Interior Health. These terms are stated under the operating permit that is issued by Interior Health, which is mandatory under the British Columbia Drinking Water Protection Act and the Drinking Water Protection Regulation. This report will provide information on the source, treatment and distribution of Invermere s water, any maintenance done on the system, and a summary of water quality results for biological, physical, and chemical parameters for The District water comes from both surface and groundwater for treatment and distribution. The surface water being stored at the Paddy Ryan Lakes is located west of town at a higher elevation and is distributed by gravity, making it a preferential source as it is more cost-effective than the groundwater that must be pumped from Athalmer to Mount Nelson Reservoir for treatment and distribution. Therefore, the surface water was used regularly in 2016 and the groundwater was used when necessary; the Athalmer well only supplied water from September to December in 2016 and only operated during the day and for certain neighborhoods. This was partly due to maintenance being done on the system. District water operators sampled raw and treated water at both treatment plants, and treated water throughout the distribution system on a daily, bi-weekly, monthly, quarterly, and annual basis depending on the parameter. District staff analyzed ph, temperature, turbidity, dissolved oxygen, oxygen-reduction potential and chlorine themselves. Samples were also sent to CARO Laboratories in Kelowna to be analyzed for microbiological, physical and chemical parameters. Data were sent to Urban Systems for data analysis and compilation. All results were within the guidelines set by Health Canada and Interior Health. Invermere s water does not undergo treatment of viruses and protozoa, such as Giardia lamblia and Cryptosporidium parvum, which is part of the multi-barrier approach emphasized by Interior Health. However, an upgrade to the Paddy Ryan water treatment plant was approved in 2016 and will be funded by the New Building Canada Fund in It will include a UV treatment facility, which will allow the District to meet all Interior Health objectives. Routine maintenance was completed for the distribution system in 2016 including annual valve actuation and water main flushing. There were several breaks in the system, including pipes at Mount Nelson reservoir and in the CastleRock community, which were both fully repaired. The District hired their first Water Smart Ambassador for the high water use season of More than thirty residential water assessments were completed within the District of Invermere in order to conserve water on a residential scale, and all Parks and School District irrigation systems were assessed and reported on to increase efficiency. The Columbia Basin Water Smart program ended after the summer season of The Taste and Odour Program that began in 2014 ended this year as the District received no further complaints from the public.

8 1.0 Introduction The District of Invermere (District) owns and operates a water treatment facility in British Columbia, and is therefore required to provide an Annual Report to its consumers and to Interior Health (IH). These terms are stated under the operating permit that is issued by IH, which is mandatory under the British Columbia Drinking Water Protection Act (DWPA) and the Drinking Water Protection Regulation (DWPR). This report will provide information on the source, treatment and distribution of Invermere s water, any maintenance done on the system in 2016, and a summary of water quality results for biological, physical, and chemical parameters tested in Figure 1. Invermere lies along the west coast of Lake Windermere Invermere is situated on Lake Windermere, which is a widening of the Columbia River. The community relies on the lake for many recreational purposes. However, the District does not withdraw drinking water from Lake Windermere. Instead, Paddy Ryan Lakes to the southwest of Invermere provides the majority of Invermere s drinking water. District of Invermere 2016 Water Treatment & Distribution System Report Page 7

9 2.0 District Water System Overview 2.1 Water Sources The District takes water from both surface and groundwater for treatment and distribution. The surface water source is located above town and is distributed by gravity, making it a preferential source as it is more cost-effective than the groundwater source, which must be pumped up to the water treatment plant from Athalmer for treatment and distribution. Therefore, the surface water is used regularly and the groundwater is used when necessary; the Athalmer well only supplied water from September to December in 2016 and only operates during the day and for certain neighborhoods Surface Water Goldie Creek begins in the Purcell Mountains to the west of Invermere, and carries water to the intake above Paddy Ryan Lakes (PRL). The intake feeds into a 12-inch pipe that is buried underground leading to the reservoir system, and the rest is diverted away from the system, eventually feeding into Lake Windermere. The intake is composed of several small settling ponds and fencing, and is checked regularly to ensure that debris and ice are not causing an obstruction to the pipe. These lakes form a reservoir system that store water and eventually flow into the Paddy Ryan water treatment plant. Sunlight Creek is another concentration of surface water in the area that begins at a lake on private property, taking runoff from agricultural areas. It is redirected around the reservoir system to avoid contamination, and then redirected again to the spillway at the end of reservoir 3, where it connects to Abel Creek, located below the water treatment plant. Figure 2. Paddy Ryan Lakes Water at the Paddy Ryan water treatment plant is treated with chlorine gas before being distributed to residents. This location is expected to receive an upgrade in 2017 to UV treatment and liquid chlorine. District of Invermere 2016 Water Treatment & Distribution System Report Page 8

10 Abel Creek continues from Paddy Ryan Lakes, eventually carrying water to Lake Windermere. A certain amount of flow must be maintained in this creek for habitat purposes. The spillway located at the end of Lake #3 takes water to this creek, and is monitored to ensure that a level of 3 inches of water is maintained. The Lake Windermere District Rod and Gun Club has completed restoration projects on Abel Creek to ensure sustainable fish habitat for species such as kokanee salmon. Figure 3. Abel Creek Groundwater When in operation, water from the Athalmer aquifer is accessed through a groundwater well and pumped to the Mount Nelson Athletic Park reservoir (MNAP) through a dedicated main. It is treated there prior to distribution using liquid chlorine. This water source is not distributed to neighborhoods above MNAP (Castle Rock, Westridge, Pineridge) and is instead only used during certain months, and during the day, as it requires a pump to bring it up to the treatment plant. Figure 4. MNAP Water Treatment Plan District of Invermere 2016 Water Treatment & Distribution System Report Page 9

11 2.1.3 Source Water Protection Figure 5. Watershed Protection Area IH uses a multi-barrier approach to maintaining water quality, which includes source water protection, appropriate and consistently effective water treatment, a well-maintained distribution system, routine verification of drinking water quality, and public education. Several plans have been created in order to minimize risk to account for source water protection in Invermere. These include reports titled: Source Protection Plan for Goldie Creek Watershed Source Protection Plan for Paddy Ryan Reservoirs Groundwater Protection Strategy All of these are available online at: District of Invermere 2016 Water Treatment & Distribution System Report Page 10

12 2.2 Water Treatment Plant There are two water treatment facilities for the District s source water. The first is located at the Paddy Ryan reservoir system. This facility currently uses chlorine gas for disinfection, but will receive an upgrade in the summer of 2017, which will allow it to use UV disinfection and conversion of chlorine gas to liquid sodium hypochlorite. This is expected to vastly improve the ability of this treatment plant to protect residents against potential health hazards including Giardia lamblia and Cryptosporidium parvum. It is also safer for water operators to use liquid chlorine instead of chlorine gas (Health Link BC). The second treatment facility is located at MNAP, where Athalmer s groundwater is sent to be disinfected with liquid sodium hypochlorite. Flow is monitored at both sites as well as physical, microbiological and chemical parameters (results listed in Section 5.0). Figure 6. Water treatment plant at Paddy Ryan Lakes (undergoing construction for upgrade at time of report) District of Invermere 2016 Water Treatment & Distribution System Report Page 11

13 2.3 Distribution System The District s distribution system is composed of: 2 chlorine contact chambers (1 at each water treatment plant) 2 booster pump stations (1 at Castlerock, 1 at Pine Ridge Mountain Resort subdivision)* 56 Km of water mains, ranging in diameter from 50mm to 500mm. Water is provided to approximately 1,650 water connections, including 1,500 residential and 145 Commercial, Industrial and Institutional. The District distribution system network is depicted Figure 8. *The Castlerock Booster Station services Phases 1, 2 and 3 of the Castlerock Subdivision and the Pine Ridge Mountain Resort Booster Station services the Pine Ridge Mountain Resort Subdivision. Both booster stations are equipped with backup generators to insure continuous operations in the event of a power outage, both have fire flow pumps, and both are tied into the District Supervisory Control and Data Acquisition (SCADA) system for alarm call outs. Castlerock Booster Station is equipped with continuous chlorine residual monitoring and leak detection. Water quality is monitored throughout the distribution system for microbiological and chemical parameters, as summarized in Section Figure 7.

15 3.0 Regulatory Requirements Water quality parameters must meet guidelines set by IH and the Province, as well as national guidelines. As stated above, water operators in British Columbia follow the DWPA and DWPR for treatment of both surface and groundwater. 3.1 Drinking Water Protection Regulation The regulation requires that: 1. Suppliers transport water samples to a laboratory in accordance with the procedures established by a drinking water officer (DWO). Schedule A below lists water quality standards that must be met by the supplier. 2. Suppliers monitor for total coliform bacteria and Escherichia Coli, at the frequencies set out in Schedule B. 3. A DWO may establish different sampling frequencies for a water supplier. Schedule A Water Quality Standards for Potable Water (sections 2 and 9) Parameter: Standard: Fecal coliform bacteria Escherichia coli Total coliform bacteria (a) 1 sample in a 30 day period (b) more than 1 sample in a 30 day period No detectable fecal coliform bacteria per 100 ml No detectable Escherichia coli per 100 ml No detectable total coliform bacteria per 100 ml At least 90% of samples have no detectable total coliform bacteria per 100 ml and no sample has more than 10 total coliform bacteria per 100 ml Schedule B Frequency of Monitoring Samples for Prescribed Water Supply Systems (section 8) Population Served by the Prescribed Water Supply System: Number of Samples Per Month: less than to per of population more than plus 1 per of population in excess of District of Invermere 2016 Water Treatment & Distribution System Report Page 14

16 According to the 2016 Census, Invermere now has close to 3400 residents (Census Canada). Therefore, four samples should be provided each month. The District met this requirement with the exception of January, when samples were late getting to the lab due to road conditions. The next sample was taken in early February to account for this. The District Water Operators collected samples from locations at Castle Rock, Pynelogs, Community Hall, and Public Works Shop every month, with an extra sample at various locations for the months of March, August, October, November and December for parameters listed in Schedule A. All samples were within the guidelines set by IH. 3.2 Interior Health Treatment Objectives IH outlines water quality and treatment objectives including a standard for viruses, protozoa, turbidity, and risk reduction, as well as bacteria levels accepted. It is called the treatment objective: 4: 4 log (99.99%) inactivation of Viruses 3: 3 log (99.9%) inactivation of Protozoa (includes Giardia lamblia and Cryptosporidium parvum) 2: Minimum of two barriers for microbiological protection 1: Maximum of 1 NTU Turbidity 0: Zero total and fecal coliforms The District was granted Filtration Deferral by IH in 2012, until further notice, for the Paddy Ryan treatment system, based on monitoring results from 2011 and Filtration Deferral will continue as long as all IH requirements are met; these requirements are included in the water quality monitoring plan. In 2016 the District met water treatment objectives with the exception of 3-log Cryptosporidium and Giardia inactivation. The District is also missing two treatment barriers; however, the District submitted an application to the New Building Canada Fund Program again this year, which was successful. An upgrade to the Paddy Ryan treatment facility is planned for 2017, which will include disinfection with UV light. This will allow the District to meet all water treatment objectives, including 3-log Cryptosporidium and Giardia inactivation, as well as having a multi-barrier approach in place. 3.3 Guidelines for Canadian Drinking Water Quality IH works with the federal government to ensure that Canadian Drinking Water Quality Guidelines are being met in BC. These guidelines provide limits for many water quality parameters and can be found online at: District of Invermere 2016 Water Treatment & Distribution System Report Page 15

17 4.0 Operations Staff The Environmental Operators Certification Program requires that an operator is certified for their operator system class. The District operates a Level 2 system and is under operation by three staff members (certifications listed): Dan Hecher (Water Operator): Water Treatment Level 2 Chlorine Handling Water Distribution Level 2 Dwayne Stringer (Water Operator): Water Treatment Level 2 Chlorine Handling Water Distribution Level 2 Wade Grauman (Operator in Training): Water Distribution Level 1. Bruce Forsyth (Public Works Manager): Chlorine Handling Water Distribution Level 3 Figure 9. Wade Grauman works as a water operator in addition to managing the irrigation systems that are operated by the District. Staff are responsible for maintaining adequate chlorine levels throughout the distribution system, flow and water quality monitoring, maintenance of equipment and distribution piping, handling emergencies quickly and effectively, and addressing any concerns from the public.

18 5.0 Water Quality Monitoring The Paddy Ryan water treatment plant is located just below the Paddy Ryan Reservoir system, and is fed by the third reservoir. The second water treatment (MNAP) plant pumps groundwater from Athalmer. 5.1 Monitoring Plan The District was granted Filtration Deferral status again this year by Interior Health, due to the good water quality at Paddy Ryan Lakes. Invermere s water operators collected approximately 1000 water samples at the PRL treatment plant and 300 water samples from the Athalmer groundwater well in Some parameters were tested daily by the operators on site including: ph, turbidity, temperature, and chlorine residual (for treated water). They also sent samples to a certified lab in Kelowna (CARO) for further testing, as agreed upon with IH. Table 1 outlines how often and where the most relevant parameters were sampled in Invermere in A more detailed schedule is included in Appendix A. Table 1.

21 5.2.2 Athalmer Well Water Quality When necessary, the Athalmer groundwater well is utilized as an additional water source for the District. Water is pumped from the well to the water treatment plant at MNAP. Since this water is coming from ground, it is not tested for microbiological parameters that surface water is susceptible to. Treated water quality results are listed in Table 4, and relevant raw water quality results are listed in Table 5. Table 4.

22 5.2.3 Distribution System Various water quality parameters are measured throughout the distribution system by District water operators. Sampling locations are indicated on Figure 1 (see Section 4.3 Distribution Network). Some parameters were measured daily: ph, temperature, turbidity, and chlorine residual; some parameters were measured monthly (alkalinity, organic carbon, total coliforms and E. Coli); and some were measured quarterly (metals). All parameters remained stable and were within provincial and national guidelines. Because the District uses chlorine to disinfect its water, by-products may result when chlorine reacts with organic materials. Total Haloacetic acids (HAA5s) and Total Trihalomethanes (TTHMs) may have some carcinogenic effects at high concentrations (Health Canada) and should therefore be kept below their Maximum Acceptable Concentrations (MACs). Both disinfection by-products were tested throughout the system (four locations) in February, May, August, and November and are listed below with their MACs. None of the results exceeded the maximum limit. Table 6.

23 6.0 Water Quality Complaints 6.1 Complaints Summary There were very few complaints about water quality in When flushing occurred there were several reports of color in the water, likely due to manganese. The taste and odour project was discontinued in 2016 because there were no further complaints regarding this. District of Invermere 2016 Water Treatment & Distribution System Report Page 22

24 7.0 Water System Maintenance The District water operators and Public Works staff conducted routine maintenance on the water system throughout the year, including: at the water intake, the reservoirs, the water treatment plants, the pump stations, and the distribution system. 7.1 Water Intake & Raw Water Reservoirs The water intake at Goldie Creek was monitored every weekday to ensure sufficient water levels. The intake was also monitored for blockages such as plant, animal or ice debris in winter. If necessary, the creek bed is dredged of accumulating gravels. Paddy Ryan Lakes were inspected on a daily basis (weekdays) in This included inspections to monitor water levels at all three reservoirs, and to check for any blockages of the dam valves which move water between reservoirs. Figure 11. Spillway area for Paddy Ryan Lake 1 to Abel Creek; also where valve is located for water to enter water treatment plant. District of Invermere 2016 Water Treatment & Distribution System Report Page 23

25 7.2 Water Treatment Plants Both the Paddy Ryan and MNAP water treatment plants are monitored with the SCADA system. This system monitors parameters in the water quality to ensure they are not exceeding specific limits. If they do, an alarm system is utilized and a 24/7 monitoring company relays the alarm to a District water operator. There were no limits exceeded in 2016 and therefore no alarms or call-outs were made. The water treatment plant infrastructure and operating systems were checked on weekdays as well. Generators at the treatment plants were test run every two weeks. The chlorine system was inspected and the chlorine gas at the contact chamber (Paddy Ryan WTP) was changed out every 4-6 weeks. The contact chamber and reservoir were cleaned and inspected and monitoring equipment was calibrated at both plants in April Pump Stations The two pump stations were checked weekly by staff, and monitored during weekdays by the SCADA system. The generators were test run every month. Monitoring equipment was calibrated annually. Figure 12. MNAP Pump Station District of Invermere 2016 Water Treatment & Distribution System Report Page 24

26 Figure 13. New piping at MNAP Pump Station. 7.4 Distribution System General Maintenance General maintenance was performed on the distribution system which consisted of annual valve actuation and water main flushing. Corporation cocks to service lines were opened, closed, raised or lowered depending on a customer s request. Cross-connection controls at both pump stations were tested annually. There was a pipe that burst at MNAP in November 2015 which was replaced with thicker plastic piping, and at Castle Rock in October 2015 which was replaced with stainless steel. Both of these breaks were fully repaired by May There was an additional pipe break that occurred in September 2016 on 13 th Ave, which was repaired right away. District of Invermere 2016 Water Treatment & Distribution System Report Page 25

27 7.4.2 Water Main Flushing Unidirectional water main flushing occurred in spring and fall of 2016, beginning in April and September and lasting approximately six weeks for each event. This involved main valve actuation and flushing of water through fire hydrants or blow off valves. Figure 14. Water Operators flush the water mains twice a year throughout the District Cross-Connection Control Program The District s Cross Connection Control Program consists of annual testing of back flow preventers, which are located in District-owned buildings and District-owned irrigations services Water Meters Replacement There were approximately 60 meters replaced with radio heads during District of Invermere 2016 Water Treatment & Distribution System Report Page 26

28 Million Liters / Month 8.0 Water Consumption 8.1 Water Demand In addition to lawn watering and generally higher usage in summer months, Invermere experiences peak demand in the summer months and lower usage in winter months due to seasonal tourism and second home-owners (Official Community Plan 2014) District of Invermere 2016 Water Demand JAN FEB MAR APR MAY JUN JUL AUG SEP OCT NOV DEC Figure 15. Water treated and distributed in 2016 (from both treatment plants). 741,000 cubic meters (1m 3 = 1000L) were treated at the Paddy Ryan and Mount Nelson water treatment plants and distributed to consumers in Invermere in The highest demand occurred in August, with 101,000 cubic meters being distributed to consumers. The lowest demand occurred in November, with only 33,000 cubic meters being distributed to consumers. District of Invermere 2016 Water Treatment & Distribution System Report Page 27

29 8.2 Water Conservation Measures The District of Invermere joined the Columbia Basin Water Smart initiative in During high water use months, May to September 2016, the District employed a Water Smart Ambassador (Andrea Smillie) to conduct outreach in the community. Andrea was present at Farmers Markets and other displays, distributed door hangers and pamphlets, and submitted media releases regarding the Water Smart program. She eventually completed over thirty water assessments at homes in Invermere for the purpose of helping residents conserve water inside and outside. In addition, all Parks and School District irrigation systems were assessed and reported on in an effort to increase efficiency. This program ended in 2016 in the Columbia Valley, but the District continues to work on its own Water Smart initiatives. Water demand in 2016 (741,000 m 3 ) dropped from 2015 (975,000 m 3 ). This significant drop in water use may have been due to outreach efforts but was also likely due to weather conditions, as 2016 was rainy and cool compared to Figure 16.

35 Appendix A Water parameters require testing at specific intervals. For example, parameters such as ph, chlorine, temperature and turbidity require more regular testing than microbiological testing, which requires more regular testing than metals.
