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. Executive Summary Highlights of the report are: Year One Water Infrastructure Program (WIP) end of year achievements (previously communicated achievements were up to Oct 31, 2018): o Hired a cross connection control clerk mid-2018 to assist with the administration of the program, freeing up the specialist to conduct more site visits and protect more properties o Cleaned 125km of the City, 1355 valves operated o Discoloured water complaints are 35% below 2016 pre-cleaning numbers 51 broken valves were replaced Approximately 1400 valves were proactively operated (20%); the majority were within the cleaning area and the 2018 reconstruction areas. Although this is below the 30% target, valve operating numbers have greatly increased since 2016 (4%). There were 98 watermain breaks in 2018, which is less than the 5-year average of 107. Replaced approximately 3,700 aging water meters Unaccounted for water was 9.0% (under the 10% target) Installed two autoflushers - one to address low chlorine at a dead end in the system and the second in a future industrial subdivision Installed another bulk water fill station to provide customers with a protected, metered source of water termain Disinfection Procedure came into effect January 11, 2018. Changes resulted in new requirements for inspection/reporting new connections and cut and caps which created additional workload during the construction season for both reconstruction and new development. Staff inspected 117 new connections on the watermains and 44 cut and caps. This does not include tapping new services or witnessing old service abandonment. The additional workload impacted the ability to complete some maintenance programs since the work needs to be completed with minimal notice to support construction demands. A renewal application was made for the Municipal Drinking Water Licence 6 - 5 City of Kitchener Water Distribution DWQMS Management Review Areas of improvement for 2019 are: Restart the hydrant painting program Development of maintenance procedures/agreements with Region/ION/Keolis for water related works (planned and emergency response) around the LRT track area Develop mobile solutions in conjunction with the CityWorks team for water valve field inspections to minimize data entry and free up resources Continue development of a mobile solution for reporting watermain breaks to improve customer communication Strange Street Water Pumping station will be offline starting in spring 2019 for installation of a manganese treatment system, which will decrease discoloured water issues in the surrounding area. The station upgrades should be complete by spring 2020. Provide an agreement for Council approval for Kitchener to act as the Overall Responsible Operator (ORO) for dual ownership watermains (watermains that are jointly owned with the Region). Although the system currently operates this way, an agreement is required by the MECP to formalize the arrangement Bring forward the Quality Management System (QMS) Operational Plan to Council for re- endorsement Background istry of the Environment should require the owners of municipal water systems to 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 was released in October 2006. Theand , requires the City of Kitchener to be 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 imposes a statutory standard of care on persons who oversee the munici oversees the accredited operating authority of the system or exercises decision-making authority -making authority 6 - 6 City of Kitchener Water Distribution DWQMS Management Review . 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 January 1st to December 31st 2018 (INS 019-004) 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 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 (80%), treatment facilities as well as a Grand River (20%) source. ure 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)lity report is available on their website. Quality Management System Policy 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. 6 - 7 City of Kitchener Water Distribution DWQMS Management Review 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. 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. As of the end of 2018, the waterworks consists of approximately: 890.2 km of distribution watermain 759 km Kitchener owned, 25 km Dual owned (joint ownership between Kitchener and Region) and 106 km Regional owned (22 km is untreated) 67,016 water meters in service 4,424 hydrants (not including private hydrants) 7461 valves (not including service valves or hydrant valves) 6,935 Kitchener owned, 139 Dual and 387 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. Year 1 of maintenance- related work included (2018): 6 - 8 City of Kitchener Water Distribution DWQMS Management Review Watermain cleaning program - Cleaned 125km of the City, 1355 valves operated. This resulted in discoloured water complaints 35% below 2016 pre-cleaning numbers Valve maintenance and replacement programs operated 1355 valves and replaced 51 broken valves Cross connection control program - Hired a cross connection control clerk in mid-2018 to assist with the administration of the program, freeing up the specialist to conduct more site visits and protect more properties. Hydrant operation and maintenance (minor gap) as a pilot program, dips were not completed on every hydrant, rather completed on a quarter of the hydrants based largely on spring inspections and known plugged hydrants. Results of the pilot program will be reviewed in spring 2019 Underground utility locates continued to meet regulatory requirements with a combination of in-house and contract staff (16,030 locates completed). Incidents of Regulatory Non Compliance A Ministry of Environment, Conservation and Parks (MECP) inspection was completed January 31 and covered February 1, 2018 to January 31, 2019. MECP had not issued their report; preliminary findings did not identify any issues of non- compliance when the inspector reviewed documentation with the City on January 31, 2018. Action: No further action required for information only Incidences of Adverse Drinking Water There were 20 Adverse Water Quality Incidences (AWQI) during the year, one of which resulted in self-imposed Boil Water Advisories (BWA). Of the low chlorine AWQIs (6 total) o 3 were in close proximity to each other and are 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 used. Total coliform AWQIs (13 total) o 6 at regular sampling locations the sampling location for KID 85 was changed from a washroom sink to another sink. This location is regularly flushed since it is a dead end in the system. An autoflusher was installed to increase water turn-over in the area. o 7 on temporary sampling locations One E.coli AWQI - KID 116, which is an outdoor sampling station One self imposed boil watery advisory was implemented on a single house, as the water service to the property and the sanitary pipe were damaged at the same time during excavation for a main break repair. 6 - 9 City of Kitchener Water Distribution DWQMS Management Review There was one location with lead exceedances in the plumbing system, with three separate instances of exceedances (resamples). Since less than 10% of samples had lead exceedances, we can continue to complete a reduced lead sampling program in 2019. The Summary Water Report January 1st to December 31, 2018 report (INS 019-004) discusses water quality compliance further Action: No further action required for information only Deviations from Critical Control Points Limits and Response There were 98 watermain breaks in 2018, which is less than the 5-year average of 107. Of the 98, 12 were deemed to be Category 2. Category 2 watermain breaks require bacteriological sampling upon completion. Watermain breaks are weather dependent due to the frost movement with colder winters resulting in more breaks. Incident debriefs are 6 - 10 City of Kitchener Water Distribution DWQMS Management Review completed for watermain breaks. This information helps to determine priorities for replacement due to condition. 6 - 11 City of Kitchener Water Distribution DWQMS Management Review Water loss for 2018 was 9.0%; 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). 6 - 12 City of Kitchener Water Distribution DWQMS Management Review Action: No further action required for information only Effectiveness of the Risk Assessment Process A risk assessment was completed on July 30 and August 20, 2018. The purpose of the risk assessment was to brainstorm potential risks and identify counter measures, where appropriate. The following is a summary: o Reviewed additional mandatory risks associated with climate change including: long term impacts of climate change, water supply shortfall, extreme weather events and sustained extreme temperatures, chemical spill impacting source water, terrorist and vandalism actions, sustained pressure loss, backflow and failure of equipment associated with secondary disinfection. o One new critical control point was added: watermain being connected to without proper inspection/witness. There are a number of mitigations including procedures, checklists and communication o Additional risks were identified backflow protection along areas with cross-border servicing agreements, watermain inaccessibility due to lack of easement and equipment tool control. 6 - 13 City of Kitchener Water Distribution DWQMS Management Review o Other critical control points (with mitigation) include parameters exceeding legislated limits in the distribution system, backflow causing contamination and back siphoning causing contamination and chambers full of water with air relief valves. It should be noted that the annual chamber pump outs did not occur in 2018 due to workload constraints. Summary of Cross Connection Program (includes the Bulk Water Fill) as of end of the year: 2,200 services are protected by Backflow Prevention (BFP). Action: For Information Only Results of Internal and External Audits An external audit (offsite 24-month surveillance audit) was completed by a certified external auditor (SAI Global) in August 2018. No non-conformances were found; the documents and records reviewed during the 24-month surveillance audit were found to be fully satisfactory in meeting the requirements of the DWQMS Two minor non-conformances have been found to date for the 2018/2019 (Sept-Sept) audits. The communication procedure was reworked to reflect the way in which the QMS policy and annual water quality reports were communicated to the public (available on the website). Staff felt as though their suggestions for improvement were either not being acted upon or not communicated back to them. This was upgraded to a non-conformance after being an opportunity for improvement for a couple years. Several opportunities for improvement were also found and are still being investigated. Action: Follow-up is required on various minor opportunities for improvement. The communications procedure was improved to show other ways the public is communicated with, and a section was added for information that is available to the public, but not actively communicated. A continual improvement procedure was developed which includes a form for staff to submit formal suggestions for improvement, and a requirement to communicate what has been or is being done with respect to those suggestions. Results of the Emergency Response Training/Testing Emergency training for management staff was completed March 29, August 24 and November 6, 2018 Staff emergency training occurred in several sessions between February and June, 2017 (training is every 3 years). Sessions for new and missed staff occurred in March and November 2018. 6 - 14 City of Kitchener Water Distribution DWQMS Management Review 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 south-eastern 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. Valves and temporary bypasses are installed to keep water circulation in sections of the Regional main 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 will be 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. Future upgrades to Strange St Pumping station (anticipated in 2019-2020) will include additional treatment for manganese which will decrease discoloured water issues in the surrounding area. The decreased supply may impact the 2019 watermain cleaning 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: 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 valvesscheduled for spring 2019 6 - 15 City of Kitchener Water Distribution DWQMS Management Review Action: follow-up water valve meeting 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 Changes that could Affect the Quality Management System quality management system. These changes must be implemented by the end of 2019. This includes the following: o Several time based requirements being changed from annually to once per calendar year. o The Review and Provision of Infrastructure procedure including a consideration of the outcomes from the yearly risk assessment. o Infrastructure Maintenance, Rehabilitation, and Renewal element must include a long term forecast of major infrastructure maintenance, rehabilitation and renewal activities which is reviewed once every calendar year. o A continual improvement procedure, which was created in December of 2018. MECP has a draft guidance document regarding the roles and responsibilities of the ORO (Overall Responsible Operator) and OIC (Operator in Charge). Impacts are not yet known. MECP has proposed changes to the Watermain Disinfection Procedure which may impact construction activities Action: No further action required for information only Consumer Feedback The number of customer water complaints has increased from 2017, but decreased from 2016. Of these complaints, discoloured water has been the most common over the last three years. The percentage of discoloured water complaints has been decreasing since the watermain cleaning program began in 2016. There was a series of discoloured water complaints in the downtown area at the end of 2018. An isolated area was cleaned again and valves were opened. Upgrades at Strange Street Pumping Station (starting in spring 2019) will reduce the source of iron and manganese entering the system. The 2019 cleaning program will focus on cleaning this area prior to the pumping station coming back on line. 6 - 16 City of Kitchener Water Distribution DWQMS Management Review Action: Continue with proposed watermain cleaning area in 2019 (see Appendix). Resources Needed to Maintain the Quality Management System A mobile solution for inspection data entry would decrease administrative burden working towards a mobile water valve program in 2019 but there are a number of programs that could be mobile Proper completion of paperwork is an on-going struggle (e.g. valve replacements) A dedicated QMS Specialist for the drinking water system. The role is currently split between gas and water and there is a sufficient volume of work for two QMS positions. 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). 6 - 17 City of Kitchener Water Distribution DWQMS Management Review 2018 reconstruction projects were completed as per the 2018 Road & Utility Capital Forecast 2019 projects were finalized 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 road work to minimize disruptions to citizens and be cost effective. Action: No further action required for information only Summary of Maintenance Watermain cleaning - The 2018 watermain cleaning area is shown below. The light green was area completed, pink is outstanding. 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. 6 - 18 City of Kitchener Water Distribution DWQMS Management Review Approximately 124 km of watermains were cleaned, 1355 valves operated. The planned area was to clean 156 km of watermains but due to water restrictions over the hot summer and some cold weather in early December, the program had a late start and had to shut down early. The remaining area will be included as part of the 2019 program (see the Appendix for a map) A valve turning/exercising program was completed for 1355 valves the majority of valves were operated in the watermain cleaning area with additional valve operation in areas of reconstruction Hydrant maintenance - spring was completed - a contractor was hired to assist. Follow-up work is ongoing. Fall hydrant maintenance was completed as a pilot program. Dips were not completed on every hydrant, rather completed it on a quarter of the hydrants based 6 - 19 City of Kitchener Water Distribution DWQMS Management Review largely on spring inspections and known plugged hydrants. Results of the pilot program will be reviewed in spring 2019 Dead end main flushing to maintain chlorine residuals was completed in spring and fall New development areas are flushed until the subdivision is built-up There were 51 broken water valves replaced Leak detection survey 1/3 of city completed each year. Follow-up is completed on potential leaks. In 2018, approximately 335km of mains were surveyed resulting in the identification of possible service leaks: 1 service leak, 1 watermain break and 12 possible hydrant leaks. Five of the hydrant issues were resolved by tightening the operating nuts, and the remainder were not leaks. The water service leak and watermain leaks were repaired Staff inspected 117 new connections on the watermains and 44 cut and caps. This does not include tapping new services or witnessing old service abandonment. The inspection was a new requirement with the same volume expected in 2019 Anodes are installed on existing watermains whenever they are exposed (e.g. watermain breaks, valve repairs, hydrant repairs) The pilots and sense lines at Pressure Reducing Valves (PRVs) in Falconridge and Hawkswood were replaced in February 2018. Further low flow pilots and piping need to be replaced in 2019 Hydrant painting was not completed in 2018 Chamber inspections were not completed in 2018 due to staffing constraints 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 There were 20 AWQIs Water loss/unaccounted for water was 9.0%. The number of quality complaints was at 195, 48% of which were related to discoloured water and 39% 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. There were 98 watermain breaks in 2018, which is lower than the 5-year average of 107 breaks/year. This is largely due to the warmer winter. 6 - 20 City of Kitchener Water Distribution DWQMS Management Review Action: No further action required for information only Operational Plan Currency, Content and Updates There was one significant change to the Operational Plan clarification that the City of Kitchener will act as Overall Responsible Operator for the Dual (jointly owned between Kitchener and Region) watermains. Past practice has been for the City to act as ORO for dual watermains but an agreement must be signed to formalize responsibilities Action: Bring Agreement forward to Council Staff Suggestions Although many documents/maps are updated and created throughout the year for continual improvement, the following changes relating to the DWQMS were made as a result of staff suggestions: Staff suggested a final connection and cut and cap cheat sheet as well as a document clearly outlining their responsibilities related to inspections implemented in June 2018 Staff recommended revising the subdivision inspection sheets and processes to streamline, including a request for a cheat sheet document and training a workshop was held in January 2019 with staff to address. Draft documents have been prepared and are circulating for comment Action: Roll out revised forms/training for subdivision inspection Other Water Meter Replacement - 3700 aging water meters were replaced. There are 67,016 meters in the system with a backlog of approximately 16,000 meters to be replaced (replacement is targeted at 15 years for residential meters). Water Consumption Trends water consumption has increased in 2018 as it was projected to do (population demand outpaces water conservation measures). It was a dry summer so it could be that the trend may fluctuate a bit based on weather until population growth demands outpace water conservation measures. It should be noted that the sanitary fees are based on the water consumption data so when consumption declines, it impacts both the water and sanitary budgets. 6 - 21 City of Kitchener Water Distribution DWQMS Management Review Locates - Kitchener Utilities and their Locate Service Provider physically locate gas and water infrastructure for contractors prior to construction and excavation work. Approximately 16,030 locates were completed in 2018 which is slightly below 2017 levels. It is anticipated that the need to provide locates will increase due to however development planned in 2019. 6 - 22 City of Kitchener Water Distribution DWQMS Management Review Action: No further action required for information only 6 - 23 City of Kitchener Water Distribution DWQMS Management Review Appendix Water Distribution System Map 6 - 24 City of Kitchener Water Distribution DWQMS Management Review Discoloured Water Locations and Proposed 2019 Cleaning Area Map 6 - 25 City of Kitchener Water Distribution DWQMS Management Review 6 - 26
