Building a Water Efficiency Program

 

January 13 : 11:00 am – 12:30 EST

One thing that has become clear as we look at water efficiency programs across Canada is how diverse the experience, drivers and progress are across the country. This session will explore this reality by presenting three case studies of utilities at very different places in their water efficiency journey, to explore the greater themes of what is driving water efficiency, water are the barriers, and what does the future of water efficiency look like.

City of Vancouver Water Efficiency Program: at a Crossroads.

Neal Klasen, City of Vancouver

The City of Vancouver has abundant fresh water resources and historically did not encounter supply or infrastructure related challenges faced by many other municipalities in North America.  However, population growth combined with the effects of climate change has pushed water conservation up the priority list. 

Vancouver has done all the “right things” to date: plumbing code changes, watering regulations, metering ICI customers, system leak detection, etc.  Yet more than 70,000 single family homes remain unmetered and per capita water consumption has not really changed for the past few years. Metro Vancouver, the regional water supplier, is now facing billions of dollars in supply upgrades. 

As the largest user on the regional system, the City of Vancouver must take bigger, bolder steps.  But what are those steps?  Is universal metering really the best solution?  Are we missing something obvious?  With these and other questions, Vancouver sits at a crossroads with many important decisions to make.

Looking back and into the future – where to next when your programs have matured

Heather Yates, City of Guelph

Constrained by their groundwater supply, the City of Guelph celebrates over 20 years of water literacy and community commitment to sustainable water use. In December 2021, the City completed an update to their Water Supply Master Plan. Through preparing the plan, success in water conservation, efficiency and demand management were evaluated. Investments in reclaiming non-revenue water, fast-tracking natural savings typically achieved through years of market transformation and engaging thousands of residents and businesses in retrofitting and renovation for efficient use of water has actively contributed to maintaining a cost effective and sustainable water supply.

On the coattails of this Master Plan, the City will commence the fourth edition of their efficiency strategy – the means in which water efficiency programs are identified. But what remains left to do? What have we learned that can be applied to the future of programs? Or are programs a thing of the past?

    Strategic Energy Management and A Net-zero Emissions Future - Pine Creek WWTP

    Morris Liu, City of Calgary and Chris Tse, City of Calgary

    The Pine Creek (PC) WWTP Energy Audit project assessed the energy consumption patterns by process area, identified energy and GHG emission reduction opportunities around the plant, and provided high level estimate of potential financial and environmental benefits.

    The prioritized Energy Management Opportunities (EMO) were furthered investigated at a more detailed level in the PC WWTP Energy Recovery (ER) Study project. The EMOs investigated include energy data collection, blower and process optimization, biogas utilization by co-generation etc. It identified the gaps that need to be closed to reach our goal of net energy neutrality. The operational, maintenance and capital recommendations were developed to reduce the energy consumption, GHG emissions and to boost the recovery of the embedded energy potentials.

    A road map to the plant energy neutrality status was developed for consideration during long term infrastructure planning. The GHG emissions reduction from these EMOs are also assessed to support a climate change action plan.

    The phased approach in exploring the energy management potentials and the pathway to a net-zero status at the PC WWTP minimized the missing areas, avoided effort spent in unfeasible ideas, either financially or technically.  

    Plan for a Net-zero Utility with Energy Audit

    Qing Zhang, Epcor

      • Will describe the energy audit process in action for EWSI Water Treatment Plants, Reservoirs, and Booster Station.

    Introducing the ISA62443/IEC62443 Series of Cybersecurity Standards & Applying them to Municipal Water SCADA Systems

    Graham Nasby, City of Guelph

    In 2002, the ISA (international society of automation) brought together industrial cyber security experts from across the globe to develop a series of standards to provide best practices for industrial automation and control system cybersecurity. This group of experts became known as the ISA99 committee, who develop and maintain the comprehensive suite of ISA-62443 (and IEC-62443) cyber security standards. These consensus-based technical standards are now available to guide both designers and users of industrial control systems. In addition to a design and policy framework, the 62433 series of standards also provide cybersecurity guidance – and minimum requirements – for manufacturers who develop and sell industrial control equipment. The 62443 series of cybersecurity standards continue to be actively developed, with many of the individual standards now on their third update.

    This presentation, by a member of the ISA99 committee, provides an overview of how the 62443 series of standards have been developed specifically for the needs of the Operational Technology applications in critical sectors public water utilities. The talk will highlight features of the 62443 standards, and how they can be readily applied to the design and day-to-day management SCADA and other critical systems in Water utilities. Insight will also be provided into how the 62443 standards can be used in conjunction with other more general industry standards such as the ISO 27000 series, CIS20, NERC CIP and NIST CSF. Lastly, several examples of how ISA-62443 series of standard has been applied to the critical control systems used by municipal water utility for a city of 140,000 people will be discussed.

    A Case for Cyber Resiliency

    Thomas L. Kuczynski, District of Columbia Water and Sewer Authority

    Cyber threats to the water sector are rapidly intensifying; and the range of actors is expanding. The impacts can be far reaching from a minor inconvenience to a major interruption in service.

    As automation and digitization become more ubiquitous and the sophistication of cyber-attacks increase a paradigm shift in the water sector is necessary and utilities need to transition their thinking from cyber security to cyber resiliency if they are to ensure continuity of operations. Unlike cyber security which focuses on protection, cyber resiliency emphasizes a company’s ability to mitigate damage (damage to systems, processes, and reputation), and maintain operations if systems and/or data have been compromised.  The ability to quickly isolate an attack, prevent or minimize damage, and finally recover are essential capabilities to achieve cyber resiliency.

    Innovative Solutions to Lagoon Dredging in a Northern Yukon Community

    Lambourne Environmental was contacted to see if we could provide dredging services to a remote Yukon community within the Arctic circle.  The community of Old Crow needed to rehabilitate their existing wastewater lagoon, removing the accumulated sludge from the cell as well as removing the vegetation growing around and in the cell.  All equipment used on the project needed to be able to fit on a commercial aircraft for transport to the site.  While some of the equipment required did not yet exist that would do these multiple tasks, Lambourne staff were able to design and build a dredge that would provide both sludge removal and also remove the vegetation from the cell.  Over the course of 2 seasons, and amidst COVID, the project was a success and the lagoon was rehabilitated and functioning efficiently.

    A Synopsis of Biosolids Management Practices in Western Canada

    Urban centres and rural municipalities in Western Canada have sufficient land to complete direct land application of treated biosolids resulting in significant benefits such as the recycling of valuable nutrients to agricultural land.  The four seasons of the year require some jurisdictions to have multiple approach to accomplish the sustainable reuse of biosolids in many centres across Canada and specifically Western Canada. This synopsis will review the approaches that both large and small centres are taking for biosolids management to sustainably manage this by-product resource at different times of the year.

    New and On-Going Challenges in Drinking Water Quality

     

    January 20: 11:00 AM – 12:30 PM EST

    Drinking water quality, and consumer perception of that quality is greatly impacted by numerous factors. Water utilities are finding themselves grappling with new challenges – from the growing threat of algal growth due to climate change to shifting water taste due to changing water chemistry. This session will explore these emerging challenges in water management – from detection to public outreach.

    Presentations

    Consumers’ Perceptions of Drinking Water: Odors, Anosmia, and Parosmia

    Andrea M. Dietrich, Virginia Tech, USA 

    The myriad of earthy-musty odorants, and variable human perception of these odors, is an increasing challenge for water professionals who desire to identify and control aesthetic issues and increase customer satisfaction. Earthy-musty odors in drinking water are frequently, but not always, the result of geosmin and 2-methylisoborneol which are produced by naturally occurring cyanobacteria and actinomycetes. Other biologically and chemically produced earthy-musty odorants in water include the haloanisoles and pyrazines, both of which are increasingly being identified in source waters and in tap water. Added to the difficulty of identifying which odorant causes earthy-musty is the complexity of the human sense of smell. People vary in their sensitivity to specific odorants and also may have specific anosmias where they cannot detect select odors or even parosmia which is a distorted sense of smell.  Another complexity is that inconsistent descriptors many be used by different people to describe the same chemical odorant. This presentation will address the diversity of earthy-musty odorants and the varying ways humans perceive and describe odors. 

     

    ATRAPP – Algal Blooms, Treatment, Risk Assessment, Prediction and Prevention Through Genomics

    Sebastien Sauve, City of Montreal

    Genetic biosensors to forecast cyanobacteria toxic blooms: a novel technology available as user-friendly kits of reagents.

    Sandra Lagauzere,  Microbia Environment

    Microbia Environnement offers a cutting-edge molecular technology, that provides a fast, specific and sensitive tool for the detection of cyanobacteria and the prediction of toxic bloom occurrence in environmental waters. It relies on genetic biosensors recognizing specific cyanobacteria fingerprints and revealing their actual metabolic activity, thus their growing trend, using a simple ELISA-type colorimetric assay. Applied to high-frequency monitoring, this unique method matches with the needs of high-throughput and cost-effective capacities which are essential for improving current surveillance programs and early warning systems. Besides reglementary methods, it provides waterbody managers and drinking water utilities with a true standardized and self-monitoring capacity to anticipate cyanobacteria blooms and to engage proactive decision-making. Regarding the importance of water preservation in Canada, and the exemplary concern of both citizens and stakeholders, the solution brings concrete perspectives to protect people, pets and wildlife and to preserve economic activity around water bodies threatened by microbial contaminations.

    National Adaptation and Mitigation Case Studies

     

    January 25: 11:00 AM – 12:30 PM EST

    This session will explore key issues in the Water Resources chapter from Natural Resources Canada’s “Canada in a Changing Climate: National Issues” report along with case study presentations from across the country on adaptation and mitigation on a local level.  Firstly the authors of the Water Resources Chapter in the National Issues Report will provide a summary on the chapter and a national overview on the preparedness of the country to climate change pressures.  This will be followed by case studies from across the country ranging from assessing vulnerability of infrastructure to climate change in Halifax, Nova Scotia, quantifiying GHG emissions from treatment facilities in Toronto, to adapting to climate change pressures in the Okanagan Basin out in the west of the country.

    Presentations

    “Canada in a Changing Climate: National Issues” report Water Resources Chapter Summary

    Hayley Carlson, University of Saskatchewan and Alain Pietroniro, University of Calgary

    Global climate change has already affected Canada’s cold-dominated water cycle, and while future changes are uncertain, they will include risks of reduced water availability, drought, and extreme rainfall. To adapt to uncertainty and changing conditions, Canadian water organizations are beginning to embrace exploratory modelling, scenario exercises and adaptive management, and enhance coordination across new institutional arrangements. At the same time, adaptation is a local, place-based process and capacity challenges are often concentrated in rural, northern, and Indigenous communities. Water practitioners cannot always access the high quality, locally relevant data they need to reduce vulnerabilities in systems and infrastructure. Canadians support action on water-related risks, but the issue competes for public attention and many Canadians remain unaware of the efforts required to meet adaptation goals. Ultimately, Canadian organizations and institutions remain unevenly prepared to manage water-related risks associated with climate change.

     

    Local Experience 1: Halifax Water Vulnerability to Climate Change Risk Assessment

    David Blades, Halifax Water

    In 2019, Halifax Water created a climate change adaptation framework within the utility’s Long-Term Planning Framework. The adaptation framework is a three-stage process: Assessment, Action Plan, and Implementation. Many industry best practice frameworks studied during development of the Halifax Water adaptation framework stop at the assessment stage. However, the Halifax Water framework identifies how an infrastructure asset progresses from the stage where risks are identified and assessed through development of an adaptation strategy to implementation.

    Halifax Water is currently completing a pilot vulnerability to climate change risk assessment study for two of the utilities fourteen asset classes. This presentation will provide an overview of the “Vulnerability to Climate Change Risk Assessment – Water Supply Plants and Water Supply Dams Asset Pilot” project; lessons learned during the pilot; and how the asset class level risk assessment fits within the climate change adaptation framework.

    Local Experience 2: Greenhouse Gas Emissions from Ontario Water and Wastewater Treatment Facilities

    Emily Zegers, City of Toronto

    As a growing number of governments make “net zero” pledges and declare climate emergencies, an understanding of greenhouse gas (GHG) emissions is becoming increasingly important across all sectors.  Significant opportunities exist for emissions reduction in water/wastewater operations.  However, because most utilities in Canada are not required to calculate and report on their emissions, the types and scale of the various greenhouse emissions from water and wastewater operations are not well understood. 

    In 2020 Toronto Water embarked upon a collaboration with the University of Toronto to complete an inventory of GHG emissions from its water and wastewater treatment operations.  The carbon footprint that will be developed through the study will go beyond the reportable emissions to quantify the utility’s most significant GHG impacts, both on and off sit 

    This presentation will provide an overview of the types of GHG emissions associated with water and wastewater treatment and will present emission breakdowns for two of Toronto’s facilities.  Potential process changes will be discussed in terms of their potential for reducing emissions.  Finally, a case will be presented for why even in the absence of regulation, utilities should act now to understand and reduce their GHG emissions. 

    Local Experience 3: The Okanagan Basin Water Board

    Plastics and Microplastics in the environment

     

     

     

    January 25: 2:00 – 3:30 PM EST

    Plastics have become inescapable in our daily life – from packaging, to clothing and even personal care products – plastics are everywhere. There’s growing research that plastics and microplastics are having lasting, damaging impacts on marine and freshwater environments. This session will explore not only the growing problem, but the municipal wastewater system contribution and what technologies and outreach programs are available to mitigate this growing problem.

    Urban pathways for microplastic

    Dr. Shreyas Patankar and Stephanie Wang, Ocean Wise

    Synthetic polymer microfibers account for a large fraction of microplastic pollution in aquatic environments. Ocean Wise’s Plastics Lab conducted an extensive research project on the variation in the microfiber shed rate of different consumer fabrics based on their material design and construction. Our research highlighted the importance of “first-wash” cycles and the efficacy of microfiber lint filters. A separate research project has been focused on study of urban pathways for microplastics entering the ocean like wastewater treatment plants, combined sewer overflows, and stormwater. This recently led to the development of new analytical methods allowing efficient estimates of the abundance, morphology, and chemical composition of microplastics in urban sampling environments. These methods enable the consistent, high-volume monitoring of microplastic abundance needed to identify strategies for intervention to mitigate microplastic pollution in the ocean.

    Our Ocean Thanks You: Metro Vancouver’s Microfibre Reduction Campaign

    Carol Nicholls and Dana Zheng, Metro Vancouver

    Microfibres from laundry are one of the main sources of microplastics in the ocean, a fact that is virtually unknown to the general public. In 2021, Metro Vancouver launched a campaign to reduce microfibres generated in laundry, developing creative materials that asked residents to switch to cold. Learn about how and why the campaign was developed, original research findings and what to consider when trying to change public behaviours. Having developed dozens of behavior change campaigns over the years – many of them tackling “icky” wastewater topics that residents would rather not think about – we have a pretty good idea of what does and doesn’t work.

    New and On-Going Challenges in Drinking Water Quality – chemical contaminants 

     

    January 11:00 AM – 12:30 PM EST

    As analytical methods continue to be improved and developed we are finding a wider range of chemical contamination in our freshwater ecosystems and groundwater. For example, PFAS and PFOS termed “forever chemicals” are highly persistent in the environment, and Chemicals used in a wide variety of everyday products are being found in the environment and in organisms. This session will explore PFAS/PFOS and plastics and the latest research on their presence in drinking water, and the efficacy of available technologies in removing them.

    PFAS in Drinking Water: Challenges and Solutions

    Krista Barfoot, Stantec

    The evolution of regulatory criteria for per- and polyfluoroalkyl substances (PFAS) in water in Canada has important implications for utilities with water supplies potentially impacted by various PFAS sources (e.g., aqueous film-forming foam [AFFF] releases, landfill leachate, industrial wastewater, or other industrial activities). Drawing on past project experience, this presentation will review PFAS-impacts observed in international drinking water systems and the treatment technologies applied to address elevated PFAS concentrations. Example case studies from pilot and full-scale treatment systems designed to remove PFAS – including both the application of granular activated carbon (GAC) as well as ion exchange (IX) as a high-performing adsorptive alternative – will be examined. Preliminary results from a pilot study being conducted by Stantec in conjunction with the Johns Hopkins University Bloomberg School of Public Health that directly compares IX and GAC from both an operational and a water quality perspective will be reviewed.
