REPORT HIGHLIGHTS: • The purpose of this report is to inform the decision-making authority about the status of the drinking water system. • The Kitchener water distribution system meets the requirements under the Safe Drinking WaterAct. • The strategic plan alignment is through the delivery of core services. • There are no financial implications of this report BACKGROUND: The Safe Drinking WaterAct, 2002 and Regulation 188/07, requires the City of Kitchener to be licensed to operate and maintain Kitchener's water distribution system. Some of the licensing requirements include the development and management of a Quality Management System (QMS) and Operational Plan as well as communication to the owner. The City of Kitchener became licensed in August, 2009 with a Financial Plan submitted in July, 2010. The licence was renewed in 2019. Section 19 of the Safe Drinking WaterAct imposes a statutory standard of care on persons who oversee the municipal drinking water system: "...every person who, on behalf of the municipality, oversees the accredited operating authority of the system or exercises decision-making authority over the system". This standard of care includes Council since they have decision-making authority. Part of the standard of care includes requiring system *** This information is available in accessible formats upon request. *** Please call 519-741-2345 or TTY 1-866-969-9994 for assistance. 38 owners to undertake financial planning and implement the Drinking Water Quality Management System (DWQMS). REPORT: The purpose of this report is to inform Council as the decision-making authority about the status of the drinking water system on an annual basis. The Kitchener water distribution system meets the requirements under the Safe Drinking WaterAct. There are specific areas that must be reported per regulatory requirements, which include; but are not limited to consumer feedback, results of infrastructure review, results of audits and summary of maintenance. The DWQMS requires Top Management to "report the results of the management review, the identified deficiencies, decisions and action items to the Owner". Top Management is defined as "a person, persons or group of people at the highest management level within an Operating Authority that makes decisions respecting the QMS and recommendations to the Owner respecting the subject system or subjects systems". The Owner of the water utility is the Corporation of the City of Kitchener, represented by City Council. The 2020 Management Review was completed with Top Management: Denise McGoldrick, General Manager, Infrastructure Services, Greg St. Louis, Director, Gas & Water Utilities, and Tammer Gaber, Manager, Operations (Gas & Water) as well as Matt Ryan, Manager, Training and Programs, Angela Mick, Manager, Quality Management and Water Programs and Dean Chapman, Quality Management System Specialist. The Management Review report is attached. Highlights of the report are: • COVID restrictions resulted in a slightly delayed construction and maintenance start as well as delayed training, however construction and maintenance activities were completed. It is anticipated that hands-on training will continue to be difficult in early 2021 • Year Three Water Infrastructure Program (WIP) maintenance end of year achievements (specific areas of improvement identified by WIP): o Cleaned approximately 133km of watermain. o Discoloured water complaints decreased significantly below 2019 numbers (43 complaints for 2020). The Region of Waterloo's Strange Street Water Pumping station continued to be off-line. It is believed that this was the source of many discoloured water issues prior to going off-line in 2019. The station upgrades for Manganese treatment continue. 0 45 broken valves and/or failing valves were replaced which allows for quicker isolation for water emergencies. o Approximately 1,100 valves were proactively operated (14%); the majority were within the cleaning area and the 2020 reconstruction areas. Operating valves ensures that they will work when they are needed in an emergency or for construction activities. o Completed spring and fall maintenance of fire hydrants. o Underground utility locates — continued to meet regulatory requirements with a combination of in-house and contract staff (14,403 locates completed). Approval for two additional locating full time employees was provided in 2020. 39 o Approximately 2,350 services are protected by Backflow Prevention (BFP) — total, focus is on high risk use. o A regulatory relief was provided by the Ministry to limit the fall lead testing programs (inside customer premises) to hydrants only due to COVID restrictions. A relief has also been granted for the spring 2021 program (hydrants only). • An inspection of approximately 130 air relief valves in chambers was completed identifying 5 replacement requirements for 2021. • There were 62 watermain breaks in 2020, which is less than the 5 -year average of 79. The 5 -year average dropped from 95 to 79 due to 2015 (a very cold year) no longer included to determine the 5 year average. • COVID decreased the ability to replace water meters for a number of weeks, however approximately 3,750 aging water meters were replaced when conditions allowed. It is anticipated that the 2021 contractor work volume will be increased to continue to address the backlog and meet the target of 5,000 meter replacements per year. • Implemented mobile water valve inspections which decreased the need for data entry and allowed for real time follow-up work to be scheduled. • Unaccounted for water was 9.1 % (below the 10% target). The unaccounted for water generally fluctuates around 10% (9-12%, with 10% being the 10 year average). • Pressure reducing valve maintenance was completed. • Re -vamped training programs started in late 2019, throughout 2020 and will continue in early 2021— maintenance and operation programs, DWQMS Awareness. Construction and Response training occurred in 2020 and will continue in 2021. • Efforts to address the non-compliance received in early 2020 for new watermains not being mapped within 12 months of replacement continues — see additional information under Incidence of Regulatory Non -Compliance. • Kitchener Utilities updated the website in early December to provide an accessible website to Accessibility for Ontarians with Disabilities Act (AODA) standards, better navigation, and an overall better customer experience. • Replaced watermains as outlined in the 2020 City of Kitchener Engineering & Water Utility Capital Forecast. STRATEGIC PLAN ALIGNMENT: This report supports the delivery of core services. FINANCIAL IMPLICATIONS: None.

The Drinking Water Quality Management Standard (DWQMS) under the Ministry of Environment, Conservation and Parks (MECP) requires management to review and evaluate the continuing suitability, adequacy and effectiveness of the Quality Management System at least once a calendar year and that the results of the management review, identified deficiencies, decisions and action items are provided to Council as the `Owner' of the drinking water system. Executive Summary Highlights of the report are: • COVID restrictions resulted in a slightly delayed construction and maintenance start as well as delayed training, however construction and maintenance activities were completed. It is anticipated that hands-on training will continue to be difficult in early 2021 • Year Three Water Infrastructure Program (WIP) maintenance end of year achievements (specific areas of improvement identified by WIP): o Cleaned approximately 133km of watermain. o Discoloured water complaints decreased significantly below 2019 numbers (43 complaints for 2020). The Region of Waterloo's Strange Street Water Pumping station continued to be off-line. It is believed that this was the source of many discoloured water issues prior to going off-line in 2019. The station upgrades for manganese treatment continue. 0 45 broken valves and/or failing valves were replaced which allows for quicker isolation for water emergencies. o Approximately 1,100 valves were proactively operated (14%); the majority were within the cleaning area and the 2020 reconstruction areas. Operating valves ensures that they will work when they are needed in an emergency or for construction activities. o Completed spring and fall maintenance of fire hydrants. o Underground utility locates — continued to meet regulatory requirements with a combination of in-house and contract staff (14,403 locates completed). Approval for two additional locating Full Time Employees (FTEs) was provided in 2020. o Approximately 2,350 services are protected by Backflow Prevention (BFP) — total, focus is on high risk use. o A regulatory relief was provided by the Ministry to limit the fall lead testing programs (customer premises) to hydrants only due to COVID restrictions. A relief has also been granted for the spring 2021 program (hydrants only). 3 44 .ter City of Kitchener Water Distribution Utirties �� DWQMS Management Review • An inspection of approximately 130 air relief valves in chambers was completed identifying 5 replacement requirements for 2021. • There were 62 watermain breaks in 2020, which is less than the 5 -year average of 79. The 5 -year average dropped from 95 to 79 due to 2015 (a very cold year) no longer included to determine the 5 year average. • COVID decreased the ability to replace water meters for a number of weeks, however approximately 3,750 aging water meters were replaced when conditions allowed.

The unaccounted for water generally fluctuates around 10% (9-12%, with 10% being the 10 year average). • Pressure reducing valve maintenance was completed. • Re -vamped training programs started in late 2019, throughout 2020 and will continue in early 2021— maintenance and operation programs, DWQMS Awareness. Construction and Response training occurred in 2020 and will continue in 2021. • Efforts to address the non-compliance received in early 2020 for new watermains not being mapped within 12 months of replacement continues — see additional information under Incidence of Regulatory Non -Compliance. • Kitchener Utilities updated the website in early December to provide an accessible website to Accessibility for Ontarians with Disabilities Act (AODA) standards, better navigation, and an overall better customer experience. • Replaced watermains as outlined in the 2020 City of Kitchener Engineering & Water Utility Capital Forecast. Areas of Focus are: • Proceed with improvements to the As -built process in conjunction with Engineering. A work plan has been developed to address a non-compliance associated with the length of time to map as-builts and additional resources may be required to manage. See Incidence of Regulatory Non -Compliance section for additional information. • Revise the Site Plan mapping process to map new infrastructure closer to when it becomes live/removed. • Restart the hydrant painting program with an extensive backlog of hydrants to be painted (estimate of 750). • Revised Disinfection Procedure was implemented on February 1, 2021. The revisions include allowances for >6m connections when specific conditions are met, change of backflow prevention device and a change relating to watermain break classification. Specifications, procedures, and a training program have been developed to ensure compliance. 11 45 .ter City of Kitchener Water Distribution Utirties �� DWQMS Management Review • Roll out a new solution for better tracking of Backflow Prevention/Cross Connection program. • COVID has further highlighted opportunities for mobile maintenance inspections. Modelling on the success of the mobile valve inspection, develop mobile solutions in conjunction with the CityWorks team for water hydrant field inspections to minimize data entry, provide faster deficiency follow-up and free up resources. Background One of recommendations from Justice O'Connor's Part Two Report of the Walkerton Inquiry was "The Ministry of the Environment should require the owners of municipal water systems to obtain an owner's licence for the operation of their waterworks". Justice O'Connor also recommended that the Owners and Operating Authorities of these systems implement a quality management approach to operations and management. As a result of these recommendations a Drinking Water Quality Management Standard (DWQMS) under the Safe Drinking Water Act, 2002 was released in October 2006. The Safe Drinking Water Act, 2002 and Regulation 188/07, requires the City of Kitchener to be licensed to operate and maintain Kitchener's Water Distribution System. Some of the licensing requirements include the development and management of a Quality Management System (QMS) and Operational Plan as well as communication to the Owner. The City of Kitchener became licensed in August 2009 with a Financial Plan submitted in July 2010. Section 19 of the Safe Drinking Water Act imposes a statutory standard of care on persons who oversee the municipal drinking water system: "...every person who, on behalf of the municipality, oversees the accredited operating authority of the system or exercises decision- making authority over the system." This standard of care includes Council since they have decision-making authority as the `Owner" of the system. Part of the standard of care includes requiring system owners to undertake financial planning and implement a QMS. Other Related Water Quality Reports The City of Kitchener Summary Water Report for 2020 is a regulatory report provided to Council, which provides a summary of drinking water including adverse water quality incidences and water volume. The Kitchener Distribution System prepares an annual summary of the number of tests taken within the distribution system as well as the range of the results. A copy of this report is available on the Kitchener Utilities website. 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 5 46 .ter City of Kitchener Water Distribution Utirties �� DWQMS Management Review operation of a trunk water network to distribute treated water to Kitchener, Cambridge, Waterloo, Woolwich, and Wilmot. There is a variety of groundwater supply wells (800/o), treatment facilities as well as a Grand River (20%) source. The Region of Waterloo's water infrastructure system is complex, consisting of numerous supply sources, pressure zones, reservoirs, and pumping stations. Ensuring sufficient pressure and quantities to meet current and planned growth requires a long-term, co-ordinated strategy. The Region provides annual summaries for each supply and the information is available on their website with a link available at the Kitchener Utilities website. 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 (Woolwich). The City of Waterloo's water quality report is available on their website. Quality Management System Policy Kitchener Utilities owns, maintains, and operates the City of Kitchener's Drinking Water Distribution System. At Kitchener Utilities, we are committed to supplying the City with safe drinking water. We work together as the City of Kitchener and the Region of Waterloo to keep water matters top of mind. We are committed to these principles: 1. Quality Kitchener water is safely treated and regularly tested according to government legislation and regulations for the consistent delivery of safe, quality drinking water. We are committed to maintaining and continually improving the Quality Management System and complying with applicable legislation. 2. Trust Trust us to look after your water needs by delivering quality water and reliable service. 3. Value Tap water is the most economical choice. 4. Communication We will communicate openly with the public concerning matters of drinking water quality. 0 47 Kitchener City of Kitchener Water Distribution Utilities DWQMS Management Review PART B — MANAGEMENT REVIEW System Description The scope of the waterworks begins at the point where treated water enters the watermain from the treatment facilities and ends at the property lines of the consumers. There is no storage, chlorine boosting, secondary disinfection or pressure boosting within the control of the waterworks. At the end of 2020, the waterworks consists of approximately: • 903.6 km of distribution watermain — 770 km Kitchener owned, 23 km Dual owned (joint ownership between Kitchener and Region) and 111 km Regional owned • 68,714 water meters in service. • 4,565 hydrants (not including private hydrants). • 7,614 valves (not including service valves or hydrant valves) — 7,053 Kitchener owned, 127 Dual and 433 Regional. (See Appendix for a map at end of this document) The waterworks system has the following permits and licences: • Municipal Drinking Water Licence • Drinking Water Works Permit • Financial Plan • Operational Plan Water Infrastructure Program The Water Infrastructure Program (WIP) was initiated in spring 2017. Targets for Year 3 of maintenance -related work were achieved, included: • Watermain cleaning program - cleaned 133km of the City. • Valve maintenance and replacement programs — operated approximately 1,100 valves and replaced 45 broken or failing valves. • Hydrant operation and maintenance — completed as required. • Underground utility locates — continued to meet regulatory requirements with a combination of in-house and contract staff (14,403 locates completed). • Approximately 2,350 services are protected by Backflow Prevention (BFP), approximately 2,400 still require protection. The exact number of devices will not be reportable until the new system is fully operational, anticipated in late 2021/early 2022. 7 48 .ter City of Kitchener Water Distribution Utirties �� DWQMS Management Review COVID Impacts • Delayed start to the construction season compressed several activities which would normally have been spread out. • Late start to the spring maintenance program, however the programs were caught up over the fall. • Training was halted from mid-March until October 2020 and again in late December 2020. Training for 2021 has been initiated remotely with one-on-one practical components. • Reallocated a portion of static hydrant checks that are normally given to a contractor for in-house staff to complete. This was work best suited to the single person vehicles at the onset of COVID. • Hydrant painting contractor was unable to retain staff and was unable to undertake painting. Hydrant painting was not completed. • Water meter replacement work was deemed non-essential and as a result of needing to enter private residences was not completed from mid-March until August. This resulted in a backlog of open service orders for meter issues and fewer meter replacement. Contractor could not start their replacement work until July. Normally 2,600 replacements are provided to the contractor but an additional 500 were given after restrictions lifted. The contractor completed 3,000 replacements in 2020. The contractor will be given an increased volume to address the backlog in 2021. Some customers are not comfortable with entry into the homes. A second shut -down commenced on December 26, 2020. • Water consumption dipped in March as businesses closed then largely recovered. The hot summer combined with many people working from home resulted in more water use. • Internal investigations for poor pressure and water quality were largely completed from outside the home. If samples were required, they were taken from the hose bib. Dispatch troubleshooted potential internal issues with customers to minimize staff visits. • Regulatory requirements for sampling — temporary hose bib samples were used to meet regulatory requirements. A relief was provided from the Ministry to slightly decrease the number of samples per month until August. Additional community sample sites were added in the fall due to hose bibs not being available over the winter months. A second relief request was submitted at the end of 2020 for early 2021to decrease the number of samples as community centres and other business close. • A regulatory relief was provided for the fall lead sampling program — hydrants were only sampled, no internal sampling. A request for relief from the spring 2021 program has been granted. • An additional flushing program was developed in areas where a lot of businesses were closed to maintain the chlorine in the system. Communications to businesses, including City facilities were made regarding flushing after a long period of closure. 49 Mtchener� City of Kitchener Water Distribution Utilities DWQMS Management Review • Temporary watermain connections were made at the curb stop instead of inside the home, resulting in an additional workload for Revenue staff to modify accounts. To minimize these impacts in 2021, changes will be made to customer communications regarding temporary watermains and water charges during construction. • Staggered shifts to reduce the number of staff congregating at shift start and end has decreased efficiency, however a second emergency response vehicle (263) has been added to divide out the immediate response work. Incidents of Regulatory Non Compliance A Ministry of Environment, Conservation and Parks (MECP) unannounced inspection was completed July 30, 2020 and covered January 1, 2020 to July 30, 2020. There were no notices of non-compliance. A previously identified Non -Compliance noted: The owner did not have up-to-date documents describing the distribution components as required. Condition 3.5 in Schedule B of the DWWP requires the City to update the 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. The work plan was submitted in 2020 and work continues to map the infrastructure within 12 months. A number of meetings with internal staff, Regional staff and consultants were undertaken to stress the importance of the timeliness of as-builts as well as to improve the process as follows: 2020 Changes • As a result of a Consultant meeting, a First Submission Asset Drawing Checklist — for consultants to double check common errors before submission was developed (November 2020) • Kitchener Utilities will not conduct final water inspections until as-builts have been received and mapped in GIS (accepted drawings) • Tracking of Initial Acceptance dates and if a submission has not been received within 3 weeks, escalation. The Letter of Credit will not be reduced until the As -Recorded and Asset drawing submission has been accepted. • Region will map all infrastructure on their projects each year rather than waiting until the final year for as-builts. Previously KU would map Regional/City infrastructure associated with Regional projects infrastructure. 0 50 Kitchener City of Kitchener Water Distribution Utilities DWQMS Management Review • Proposed drawings are entered into GIS with a purple boundary to flag that the existing information may have changed. Once as-builts are received, purple boundary is removed. • Water As -Built Drawing Work Instruction Procedure finalized in November 2020. • Email of all project status with GIS is sent out monthly by GIS (Action Required: Outstanding Engineering Digital Submission Projects). This is generated as soon as proposed drawings are entered into the system. • KU may map important watermains in an interim status. Generally, these are Regional watermains. • Engineering Graphics Technologist vacancy in 2020 will be filled in 2021 (reconstruction as-builts) • Backlog of older new development and reconstruction drawings was largely addressed. Once the backlog is cleared, it is anticipated that the improvements to the process will result in timelier as-builts. 2021 Proposed Improvements • Storyboard — to be posted on the Development website. This tool will guide users through the checking/correction process. • Attribute template — 2021 version will include removals — for example anodes, hydrant bends, storm and sanitary manhole cover, storm pipe depth, bedding info will be removed to streamline data collection. Individual utilities have reviewed their data requests and removed some non-essential items. • Topology fixer — GIS will complete the topology changes and not send these errors back to the consultants. • Attribute checker — there will be an app where consultants can check their data first without providing it to GIS to run the checker. • Red -lined reconstruction drawings are entered into GIS as drawings (not mapped) as a resource for locators. • Interim as -recorded at end of construction season for multi-year reconstruction projects. • Additional resources may be required, if process improvements do not achieve the regulatory requirements to map the drinking water infrastructure changes within 12 months. Incidences of Adverse Drinking Water There were 42 Adverse Water Quality Incidences (AWQI) during the year, six of which resulted in self-imposed Boil Water Advisories (BWA). The volume of AWQls increased over 2019, the majority of which were related to temporary watermains used during construction. 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. Warmer weather seems to increase the incidences of Total Coliform. The additional challenge 10 51 Kitchener City of Kitchener Water Distribution Utilities DWQMS Management Review with temporary watermains is the sample port is located outside and subject to unsanitary conditions. Many contractors remove the sampling ports when not in use because they are subject to vandalism/theft. These ports need to be maintained in a sanitary condition between uses. 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. Additional communications efforts to contractors regarding the importance of maintain the sampling ports in a sanitary manner will be made over the 2021 construction season. • Of the low chlorine AWQIs (13 total) o Eight were in areas of new subdivisions with no houses yet built. Along with dead ends, KU proactively flushes new areas until there are homes built and water is being used. • Total coliform AWQIs (22 total) o 21 were at temporary sampling locations. • Lead: o No lead adverses were reported in 2020. Due to COVID, the fall lead program was reduced to sampling for lead at hydrants (relief was granted by the Ministry). o For private side exceedances, the City is not obligated to complete any additional corrective actions other than reporting, unless directed under the Medical Officer of Health. • Six self imposed boil watery advisory were implemented — four due to potential sewer contamination as a result of private side water service damage, one due to potential contamination from sewer damage during a watermain break and one on a temporary main. • Two high sodium adverses at the same location. Correction actions, other than reporting, are not required. Sodium is a common element in the natural environment and is often found in drinking water. It can occur naturally or be the result of nearby road salt applications. Sodium in drinking water is not a health concern for most people but may be an issue for someone with hypertension, congestive heart failure or on a sodium - reduced diet. Those on sodium restricted diet should consult their physician. Public Health has an information document regarding sodium in drinking water. • The Summary Water Report for 2020 discusses water quality compliance further. Action: No further action required — for information only 11 52 .,,,,.,r6l City of Kitchener Water Distribution DWQMS Management Review Adverse Water Quality Incidents (AWQIs) Deviations from Critical Control Points Limits and Response • There were 62 watermain breaks in 2020, which is less than the 5 -year average of 79. Of the 62, 9 were deemed to be Category 2. Category 2 watermain breaks require bacteriological sampling upon completion. The 5 -year average decreased due to one of the high watermain break years being outside this window. We have been investing in watermain replacements which have reduced the number of watermain breaks. Watermain breaks are also heavily weather dependent due to the frost movement with colder winters resulting in more breaks (2020 was a relatively mild winter). Incident debriefs are completed for watermain breaks. This information helps to determine priorities for replacement due to condition. 12 53 r6l City of Kitchener Water Distribution DWQMS Management Review Number of Watermain Breaks by Year 13 54 r6l City of Kitchener Water Distribution DWQMS Management Review 14 55 r6l City of Kitchener Water Distribution DWQMS Management Review • Unaccounted for water for was 9.1%; the MECP target is 10%. Water loss includes water used for construction watermain commissioning (e.g. new mains and replacement mains), water for temporary main supply during reconstruction, and water use for reactive flushing (e.g. discoloured water). The 10 -year average for Kitchener is 10%, although the percentage fluctuates. Percentage Unaccounted For Water Action: No further action required — for information only Effectiveness of the Risk Assessment Process • A risk assessment was completed on November 17, 2020. The purpose of the risk assessment was to brainstorm potential risks and identify counter measures, where appropriate. The following is a summary: 15 56 Kitchener City of Kitchener Water Distribution Utilities DWQMS Management Review o Reviewed all risks to ensure all information and assumptions are current and valid. Also discussed the following new potential risks: ■ Risk of leaving valves closed (e.g. during watermain cleaning) ■ Risk due to the number of C&M Supervisors currently being low ■ Risk of not meeting sampling numbers due to COVID o Preventive or Control measures updated for several existing risks and added for the three new risks above. Revised risk assessment table. o Risk C15, lack of drawings along LRT, was marked as completed. Action: For Information Only Results of Internal and External Audits External: • An external audit (12 month surveillance audit) was completed by a certified external auditor (SAI Global) in November 2020. No non -conformances were found. One opportunity for improvement was identified: o Ensure that the Continual Improvement Log is accurately completed. Several Continual Improvement items identified no preventive actions were required but actions were undertaken. Additionally, there was no documented evidence that the effectiveness of the implemented preventive action was reviewed within six months, identifying the results of the review. A further discussion with the auditor was completed to understand the definition of preventative actions. Changes to the log will be made in 2021 to address. Internal: • 20 opportunities for improvement were identified from internal audits.

Results of the Emergency Response Training/Testing • New Boil Water Advisory training was provided to supervisors and management over summer 2020/January 2021. • Staff emergency training started in late 2020 due to COVID; with the 2021 groups completing remote training in early 2021 (training is every 3 years). • Debriefs are also completed for selected events. For example, debriefs after Boil Water and Drinking Water Advisories are completed to improve our processes. Action: No further action required — for information only Operational Performance • Ongoing work with the Region for the Zone 2 and 4 Optimization — this will improve water pressures and supply in the southeastern end of the city. The majority of the work is Regional; however, there is coordination work with the City. This work is dependent on timing of development in the areas and as development proceeds, additional sections of the main are installed. One major section still requires connection (Bleams/Fischer- Hallman areas). Valves and temporary bypasses are installed to keep water circulation in sections of the Regional main. • The Region's Zone 4 Trunk Watermain project includes the installation of 750mm concrete pressure pipe watermain from the Mannheim Water Treatment plant across the southern portion of the City. Work commenced in 2017 and is ongoing. A section of the newly installed watermain between the Mannheim Water Treatment Plant and Bleams Road is temporarily being used as a Zone 5 watermain while the Ottawa St watermains are out of service for construction. • Future upgrades to Strange St Pumping station (station is currently out of commission) will include additional treatment for manganese, which will decrease discoloured water issues in the surrounding area. The decreased supply did not impact the 2020 watermain cleaning program; however, it may impact 2021 if additional water conservation is required. Action: No further action required — for information only Raw Water Supply and Drinking Water Quality Trends There are known seasonal issues with the water supply: In 59 .ter City of Kitchener Water Distribution Utirties �� DWQMS Management Review • Fall - Grand River temperature changes may cause odour challenges in the source water, which may increase flushing requirements. • Winter — temperature extremes may cause more watermain breaks in the system. Action: No further action required — for information only Follow,up on Action Items from Previous Management Reviews • Mobile project with direct data entry for water valves went live in 2020. Action: No further action required — for information only Status of Management Action Items Identified Between Reviews There were no items identified between the management reviews. Action: No further action required — for information only Chances that could Affect the Quality Management System • MECP has released changes to the Watermain Disinfection Procedure which come into effect February 1, 2021. The specifications document was revised to incorporate, additional work instructions, forms and training materials have been developed, with staff training scheduled for 2021. High level changes include criteria to allow a greater than 6 m connection, change to acceptable backflow prevention device type and categorization of watermain breaks to assume that the break is a Category 2 until proven to be a Category 1. • The Federal government has a manganese limit, however the current provincial regulations, which Kitchener is, required to follow only has an aesthetic limit. It is anticipated that the province will follow the federal guidelines and implement a maximum allowable concentration. The Strange Street upgrades are being complete in anticipation of this regulatory change. • There are indications that the lead maximum allowable concentration will be reduced, which will likely increase the number of lead tests that exceed the regulatory limits. Customers are not required to complete any corrective actions when elevated lead exists. The City is required to flush and resample if there is a lead adverse in the distribution system. The City tracks street with lead or suspected lead and includes them as part of the considerations for replacement. It is most cost effective to replace a number of lead services as part of a road reconstruction project, rather than individual services. Action: No further action required — for information only 19 W 10chener� City of Kitchener Water Distribution Utilities DWQMS Management Review Consumer Feedback • The number of customer water complaints has decreased from 2019. Due to COVID, staff were not entering homes; however, water samples were taken at hydrants or outside hose bibs, when appropriate. Dispatch staff guide customers through a number of questions to determine whether the problem is suspected to be internal or external. The majority of pressure issues are related to water softeners or other internal issues. • KU tracks the problem, cause and remedy for each complaint. The percentage of discoloured water complaints has been decreasing since the watermain cleaning program began in 2016. • Discoloured water complaints are often the result of changes in flow in the system. This can be due to reconstruction, watermain cleaning, watermain breaks, valve replacement and other construction. The number of discoloured water complaints decreased significantly once Strange St pumping station was taken offline • Low pressure complaints are largely internal issues (softeners, internal plumbing). • Other complaints include water hardness, no water, odour/taste, air in lines (white water), customer sample requests. • In general, a number of customer complaints can be resolved by educating the customer (water hardness), flushing/sampling (discoloured water) or confirming private side issue (water softener, pressure reducing valve, drain issues) • There was a Regional project which required multiple pressure zone switches to a large area in the southern end of Kitchener. The work was too large to allow for hand delivery of disruption notices (website was used when the work was planned), which resulted in a cluster of pressure complaints. 20 61 Kitchener6l City of Kitchener Water Distribution lUffies r DWQMS Management Review Distribution of Customer Water Complaints 450 450 400 400 350 350 300 300 250 250 200 200 150 150 100 100 50 50 0 0 2016 2017 2018 2019 2020 Custome r Wate r Complaints 395 242 279 295 142 ■ other 167 63 65 83 52 ■ Low Pressure 81 96 101 107 47 ■ Discoloured Water 147 83 113 105 43 Action: Continue with proposed watermain cleaning area in 2021. Resources Needed to Maintain the Quality Management System • A mobile solution for inspection data entry would decrease administrative burden —a mobile water valve program was delivered in 2020 and there are a number of programs that could be mobile. Anticipated that a mobile application for hydrant inspections will be rolled -out in 2021 • Proper completion of paperwork has improved due to additional training and collection of hard copy records. Time is spent collecting, entering, scanning, attaching, and collecting various data for operational and regulatory requirements. Action: No further action required — for information only Results of the Infrastructure Review • Individual project selection is based on a number of factors including condition (watermain break history), material, criticality, watermain size, presence of lead services, shallow mains, and other infrastructure needs (storm, sanitary, road). 21 62 Kier City of Kitchener Water Distribution Utilities �� DWQMS Management Review • 2020 reconstruction projects were largely completed as per the 2020 Engineering/Storm/Sanitary/Water Capital Forecast • The Region replaces some Kitchener infrastructure as part of their projects (Kitchener funded). • 2021 projects were finalized; however, it should be noted that there were a number of Regional projects moved out to future years in the Regional capital program. • Meetings were held with Asset Management and Engineering staff at both the City and the Region to determine future project needs. • Issue papers are brought forward as part of the budget process, additional funding requests related to maintenance and water -only capital projects. The majority of water - only projects are included as part of Regional roadwork to minimize disruptions to citizens and be cost effective. Action: No further action required — for information only Summary of Maintenance • Watermain cleaning - The watermain cleaning area is shown below. The pink area included both the leftover 2019 area as well as 2020 area, both of which were completed for a total of approximately 133km. The next map shows the proposed 2021 area in light green. The purpose of watermain cleaning is to remove iron and manganese build up in the watermains. The iron and manganese cause discolouration in the water. Although iron and manganese are naturally occurring and not health related, discoloured water causes a public perception of issues with the drinking water. Provincial health related regulations are anticipated for iron and manganese. 22 63 r6 City of Kitchener Water Distribution DWQMS Management Review d Scheduled 2020 1atrmain Cleaning 01. rIV F63 SCHEDULED - IN PROGRESS 17-1 COMPLETED 17-1 NOT SCHEDULED C&p&r &i Ttnna►tyyr kem.*du r 9.r- [ir.$paar Curdr MWe 2= 64 r6l City of Kitchener Water Distribution DWQMS Management Review • A valve turning/exercising program was completed for 1,110 valves — the majority of valves were operated in the watermain cleaning area with additional valve operation in areas of reconstruction. • Hydrant maintenance — spring maintenance was completed on all hydrants and hydrants were dipped in the fall, as required. • Hydrants are flushed to maintain chlorine residuals was completed in spring and fall. • New development areas are flushed until the subdivision is built-up. • There were 45 broken or failing water valves replaced. • Leak detection survey — 1/3 of city completed each year. Follow-up is completed on potential leaks. Approximately 300km of mains were surveyed resulting in the 24 65 Mtchener� City of Kitchener Water Distribution Utilities DWQMS Management Review identification of possible leaks: 2 possible watermain breaks — one at Mill Park Drive (no leak found) and the second at Martinglen Cres and Primrose Path (leaking water valve was replaced). There were 31 possible hydrant leaks — the majority of which were repaired by tightening the nuts of the hydrants • Staff continue to inspect new connections and cut and caps for reconstruction and new development. Staff complete all new service tappings for development as well as witness old service abandonment. This work requires 48 hours to schedule and is driven by new development and watermain replacement work. • Dechlorination procedures for hydrant flushing were developed and rolled- out to staff. • Anodes are installed on existing watermains whenever they are exposed (e.g. watermain breaks, valve repairs, hydrant repairs). • Pressure Reducing Valves (PRVs) were inspected. • An auto flusher was installed on Morrison Road to maintain water quality until future pressure zone changes can be made. • Chamber inspections/pump outs for chambers containing air relief valves — approximately 130. Air reliefs are a potential risk to the system if they become submerged and there is a watermain break or incident in the distribution system. Five chambers have been identified for replacement in 2021 with boulevard configurations, eliminating the chamber. • Staff continue to use the watermain break app for reporting breaks, which improves customer communication for breaks • Rolled out the mobile valve operating checks • New valve turning equipment allows for better valve exercising and less chance of breaking • Changed hydraulic valves to switch automatically between guillotine and pump. The faster switching to pump is anticipated to decrease the number of Category 2 watermain due to faster excavation. • Hydrant painting was not completed. • Website was updated. Action: No further action required — for information only Effectiveness of Maintenance The effectiveness of the maintenance program is determined by the following factors: • Number of Adverse Water Quality Incidents • Water loss/unaccounted for water • Water quality complaints • Number of watermain breaks 25 M .ter City of Kitchener Water Distribution Utirties �� DWQMS Management Review • There were 42 AWQIs. • Water loss/unaccounted for water was 9.1%. • The number of quality complaints was at 142, 30% of which were related to discoloured water and 38% pressure (largely internal issues). The remainders included complaints relating to hard water (new residents are not always familiar with hard water), and general safety concerns. The watermain cleaning program has decreased the number of complaints. A map of discoloured water locations is included at the back of the report. It is anticipated that the Strange Street upgrades will decrease the volume of discoloured water complaints and reactive flushing. • There were 62 watermain breaks in 2020, which is lower than the 5 -year average of 79 breaks/year. Action: No further action required — for information only Operational Plan Currency, Content and Updates • A significant number of work instructions were reviewed/modified in anticipation of the various training programs • The Operational Plan is updated annually Action: No further action required — for information only Staff Suggestions Staff suggestions are included under the new Continual Improvement section of the report. Other • Water Meter Replacement - 3750 aging water meters were replaced. There are 68,714 meters in the system with a backlog of approximately 13,700 meters to be replaced (replacement is targeted at 15 years for residential meters). • Development growth is anticipated to continue with both new subdivision, site plans and redevelopment, which creates on -demand inspection requirements for final connections, tappings and cut and caps. • Water Consumption Trends — water consumption has increased in 2020 likely due to a hot summer and more customer use throughout COVID (e.g. gardens). 26 67 Kitchener City of Kitchener Water Distribution Utilities 23,500,000 23,000,000 22,500,000 m 22,000,000 L 21,500,000 21,000,000 20,500,000 20,000,000 DWQMS Management Review Water Purchased (m3f year) 2010 2011 2012 2013 2014 2015 2016 2017 2018 2019 2020 Year • Locates - Kitchener Utilities and their Locate Service Provider physically locate gas and water infrastructure for contractors prior to construction and excavation work.
