BACKGROUND: As outlined in Schedule 22 of the Drinking Water Systems Regulation (O.Reg.170/03) of the Safe Drinking Water Act, 2002, a summary report is to be prepared and given to the members of the municipal council. The following information is required to be included in this report: (a)list the requirements of the Act, the regulations, the system’s approval and any order that the system failed to meet at any time during the period covered by the report and specify the duration of the failures; and (b)for each failure referred to in (a), describe the measures that were taken to correct the failure. The report must also includeasummary of the quantities and flow rates of the water supplied during the period covered by the report. REPORT: The following matters are reported to Council in accordance with the requirements of the Safe Drinking Water Act, for the period from January 1 to December 31, 2019: The Kitchener Distribution System is part of an Integrated Urban System, meaning the Regional Municipality of Waterloo is responsible for water treatment and the development and operation of a trunk water network to distribute treated water to *** This information is available in accessible formats upon request. *** Please call 519-741-2345 or TTY 1-866-969-9994 for assistance. 3 - 1 Kitchener, Cambridge, Waterloo, Woolwich and Wilmot. The Region provides annual summaries for each supply and the information is available on their website with a link from the Kitchener Utilities website. Reports from the connected systems have been or will be received. A portion of Kitchener (River Ridge area) is supplied by the City of Waterloo. Kitchener supplies water to a small section of Waterloo (Ira Needles area) and water travels through the Kitchener distribution system to Breslau. The City of Waterloo’s water quality report is available on their website. TheMinistry of Environment, Conservation and Parks (MECP)completed an annual inspection on January 8, 2020which covered February 1, 2019to December31,2019. The report identified a non-compliance with respect to as-built drawings. Condition 3.5 in Schedule B of the Drinking Water Works Permitrequires the City to update the water infrastructure map within 12 months of any additions, modifications, replacements or extensions to the distribution system. For further clarification, the 12-month clock starts when a watermain is commissioned and the public is able to consume the water from the respective watermain. Following the inspection findings, aseries of meetings have been held and a work plan developed to address timely as-built information. There were 3,773chlorine residual samples taken and 2,214bacteriological samples taken within the distribution system. Of these, there were 26 Adverse Water Quality Incidents (AWQI’s) reported in this time period (see attached Table 1) and all resamples were clear. An AWQI does not necessarily mean that the water is a risk to the customer. It means that a potential problem has been identified and corrective actions must be taken to resolve the problem. City staffwork with ministry staff and the local public health unit to resolve the issue, which generally includes resampling. Dead end watermainand new developmentflushing is a proactive approach to increase the levels of chlorine in the distribution system. The water is initially disinfected (primary disinfection) at the treatment plant and sufficient chlorine is added to protect the water from microbiological contamination as it travels through the pipes in the distribution system (secondary disinfection). Low chlorinedoes not pose a threat to human health; to have an impact to human health, there must be microbiological contamination and no, or extremely low, chlorine. Temporary watermains are particularly sensitive as they are above ground systems influenced by the water heating up in warmer temperatures. This may increase the potential for bacteriological growth. Due to the sensitive nature, all temporary watermains are sampled on an increased schedule (every 2 weeks at multiple locations). The additional challengewith temporary watermains is the sample port is located outside and subject to unsanitary conditions. Although efforts are made with the design of the ports to prevent contamination, sampling is not completed under ideal sanitary circumstances. The general nature of reconstruction projects often leads to “false positives”, where the results received are more reflective of what is on the sampling tap, rather than what is in the water. Every positive result is reportable and resampling must occur in accordance with regulations. When the resamples are clear, it is an indication that the issue was with the sampling port, not in the water. 3 - 2 The presence of total coliform on a test does not necessarily mean the water is unsafe to drink. Coliform bacteria can be found in many different environments. There are several different strains of coliform bacteria. Most are harmless and do not cause illness. Coliform bacteria are used as an “indicator organism” to assess the possibility of other disease-causing organisms, and their detection would prompt further investigation and/or corrective action. It is different than E.coli, which is a bacteria only associated with human or animal faecal matter. When total coliform is found, a resample is done using a different technique, which provides a number of total coliforms to analyze in consultation with Public Health and the MECP. Based on a risk assessment of a number of factors including the coliform count, chlorine residuals, and upstream/downstream coliform counts, the requirement for a boil water advisory is determined. There were two precautionary self-imposed Boil Water Advisories:one as a result of a sanitary pipe damage and the second was due to possible contamination from sewer damage during a watermain break. The sample results showed no contamination. Lead testing sampling programs were completed in February/March and September/ October 2019. There were five (5) locationswith a lead exceedance in the plumbing system and one hydrantwithin the distribution system.The hydrant is on a street that is scheduled for reconstruction. Homeowners were provided test results andinformation about lead from the Health Unit.The City is not obligated to complete any additional corrective actions other than reporting, unless directed by the Medical Officer of Health for the residential plumbing exceedances. The Region of Waterloo’s Strange Street Water Pumping station was offline starting in fall 2019 for installation of a manganese treatment system, which isanticipatedto decrease discoloured water issues in the surrounding area. The station upgrades should be complete by 2022. A summary of the quantities of the water supplied by the Regional Municipality of Waterloo during the period covered by the report is noted on the attached Table 2. Water volumes increased in 2018and this trend has continued in 2019. These trends are consistent with the Water Supply Master Plan whereby 2018 was the year that population demand was forecasted to outpace water conservation measures. 3 - 3 Table 1–Adverse Water Quality Incident Summary –January 1to December 31, 2019 NumberAdverse TypeAdverse AWQI #Site NameSite Location Date 1LeadFeb 7144756Hydrant 402528 Wellington St W 2LeadFeb 11144774Hydrant 402528 Wellington St W 3Low chlorineJun 22145795Hydrant 10083Strasburg & Robert Ferrie 4Total coliformJun 26145969Temp mainS 59 Sandra Ave 5Total coliformJuly 5146150Temp mainS3 Lot 203 Franklin St N 6Low chlorineJuly 10146263Hydrant 44111516 Glasgow St 7Total coliformJuly 22146653Temp mainS2 191 Franklin St 8Self Imposed July 2414673386-212 86-212 Boniface Ave & BWABoniface Ave 17 & 117 Massey Ave & 17 & 117 Massey Ave 9Low chlorineJuly 31146954Hydrant 10066530 Caryndale Drive 10Total coliformAug 7147142Temp mainAdelaide St SP AT3 11Total coliformAug 8147203Temp mainAdelaide St AT2 12Total coliformAug 9147208Temp mainAdelaide St AT1 13Total coliformAug 14147315Temp mainThird Ave S6 14Total coliformAug 28147667Temp mainThird Ave S7 15Low chlorineSep 9147907Hydrant 10123Tartan Ave & Beckview Dr 16Total coliformSep 11147994Temp mainThird Ave S7 17Total coliformSep 16148099Temp mainCentreville St 18Total coliformSep 25148237Temp mainThird Ave S4 19Total coliformSep 30148319Temp mainThird Ave S4 20Total coliformSep 30148322Temp mainThird Ave S7 21Total coliformOct 1148355Temp mainThird Ave S4 22Self Imposed Oct 5148423300 Fischer-300 Fischer-Hallman BWAHallman RdRd 23Low chlorineOct 31148824KID122Cedarviewbulk water fill station – near 2260 Shirley Dr 24Low chlorineNov 12148978KID78660 Belmont Ave W 25Low chlorineNov 15149011Hydrant 253343 Crestview Pl 26Low chlorineNov 25149095KID78660 Belmont Ave W 3 - 4 Table 2 -Kitchener Distribution System Volume of Water Conveyed from the Region of Waterloo Supply System 2019 Monthly Total 2019 Average Day 2018 Monthly Variance from 333 Month(m)(m)Total (m)Previous Year January1,800,42658,0781,837,462 -2.0% February1,634,92758,3901,601,872 2.1% March1,828,27258,9771,752,074 4.3% April1,720,37257,3461,656,377 3.9% May 1,834,43159,1751,872,929 -2.1% June 1,837,91961,2641,928,887 -4.7% July 2,021,90765,2232,051,087 -1.4% August1,986,44864,0791,817,469 9.3% September1,804,18860,1401,751,652 3.0% October1,781,83057,4781,724,265 3.3% November1,696,57356,5521,647,814 3.0% December1,756,99356,6771,745,053 0.7% Total21,704,28621,386,9411.5% ALIGNMENT WITH CITY OF KITCHENER STRATEGIC PLAN: The recommendation of this report supports the achievement of the city’s strategic vision through the delivery of core service.
