Water Conservation & The Water Soft Path
Communities around the world are beginning to realize the economic, social, and environmental benefits of water conservation. Planners and water managers are increasingly moving away from supply-side solutions to meet water demand (e.g. expanding physical infrastructure, such as pipes, pumps, dams, and reservoirs) Instead, they are looking toward long-term, comprehensive water management approaches that will ensure adequate quantities of water for the future.
The WSP’s water conservation work is largely focused on ways that communities can effectively implement tailored water soft path stategies to sustainably manage their water resources, now and into the future. The water soft path concept offers a holistic and comprehensive approach to water sustainability planning, and takes into consideration the complex interactions that occur between the natural environment and human activity.

Using demand elasticity as an alternative approach to modelling future community water demand under a conservation-oriented pricing system: An exploratory investigation. Canadian Water Resources Journal, available online January 26, 2015.
Water managers lack practical and readily available tools to inform them about what impact price changes (or changes in other drivers of water use) will have on demand – and therefore revenue – over both the short and long term. This paper examines how the concept of demand elasticity can be used to model changes in annual aggregate water use in response to future changes in major demand drivers including water and electricity prices, average income, population, level of business activity and climate. It does so by describing a pilot investigation completed in York Region in Southern Ontario, where a range of assumptions about price elasticities were used to calculate the rate of growth for water demand over a 40-year period. This investigation was deliberately exploratory and the findings can only be considered indicative and preliminary. However, with further development, the modelling approach described could provide an additional tool to help water managers understand changes in demand, and communities make the transition to a conservation-oriented water pricing system.

Water soft paths begin from the vision that future water management has more to gain from reducing demand than from increasing supply. This article reviews three case studies of water soft path analysis in small urban areas in Canada, and one study of an urban planning process incorporating soft path concepts. The analytical studies indicate how communities can avoid the need for expansion of water infrastructure with negligible impacts on lifestyles or livelihoods. The planning study demonstrates that it is possible to introduce water soft paths early in a review, and that this will stimulate more ecologically sensitive thinking among citizens, officials and political leaders. Similar conclusions can be expected from soft path studies in urban areas elsewhere in the developed world.

The current study extends past work on water soft path analysis in breadth and in depth: in breadth by studying an area devoted to large-scale prairie agriculture, and in depth by adding direct interaction with water managers and citizens of the Pembina Valley Conservation District in the Province of Manitoba, Canada. The main conclusion from the study is that the region can continue to be a prosperous and attractive place in which to live and to farm for at least 30 years without a single additional drop of water.

The best way to achieve a sustainable future for fresh water is to develop decision-making processes, institutions, and technologies that emphasize both efficiency and conservation. These two terms are commonly treated as synonyms, but, respectively, they reflect anthropogenic and ecological bases for making decisions. Recognizing that both perspectives are valid, this article outlines a new approach to water planning and management called the water soft path. This approach differs fundamentally from conventional, supply-based approaches. The article reviews the transfer of the original soft path concept from energy to water, and summarizes the first applications of water soft path analytics to specific geographic areas: one urban area, one province, and one watershed in Canada. The article concludes with suggestions for further research, as well as steps to improve recognition of the water soft path as a planning tool that can move management and policies towards economic, ecological, and social sustainability.

Brandes, O.M., & Kriwoken, L. (2006). Changing perspectives--changing paradigms: taking the "soft path" to water sustainability in the Okanagan Basin. Canadian Water Resources Journal, 31(2), 75–90.
Access to fresh water is vital to Canada's long-term prosperity. Water is the foundation of our economy and communities, and is essential for all forms of life. Yet despite its critical importance, water is undervalued and often wasted. Perceived as an abundant and virtually limitless resource, the myth of abundance is entrenched even in water-stressed areas such as the Okanagan, where drinking water supplies are at risk, conflicts among water users are common, economic opportunities are threatened, and aquatic ecosystem health and fisheries are declining. Population growth, coupled with the uncertain (yet increasingly evident) impacts of climate change, will only increase these challenges in the future. Water conservation and demand management are critical components in a lasting long-term and sustainable approach to water management. Demand management offers a genuine win-win solution as communities reap both environmental and economic dividends from reducing water use. To demonstrate that conservation is the next best source of "new" water in regions where supply is limited, this paper outlines opportunities to move toward more sustainable water management. A comprehensive and long-term approach to water demand management, referred to as the "soft path," requires active participation by water users and effective strategic planning to create the appropriate mix and timing of conservation measures for the region. Lasting solutions require changes in attitudes and opinions about water and must draw on innovative tools and best practices from other jurisdictions to create a basin-wide and comprehensive "made in the Okanagan" approach to sustainable water management.

A report for the Capital Regional District's Water Advisory Committee outlining ways to apply the soft path in a municipal setting.
Soft path planning employs backcasting—a planning approach that begins by envisioning possible future states, then works backwards to connect a desired future to the present by integrating policies, programs, and technological innovation. This report applies the Urban Water Soft Path “Back of the Envelope” Backcasting Framework (BEBF) to compare various possible scenarios of future water use at the community scale (e.g. municipal, regional). The framework involves the application of an analytical tool to determine the macro impact of different “packages” of micro measures (e.g. policies, programs, technologies) on total water use. The main goal is to illustrate the potential of a comprehensive approach to water conservation and efficiency, with the initial results pointing to recommendations for specific actions in the future.
The WSP's Oliver M. Brandes co-authored a backgrounder on the soft path for water as part of the "Freshwater for the Future" issue of the federal government publication Horizons, published by Policy Horizons Canada (p. 71-74). WSP research is also mentioned in the article on a national freshwater policy framework (p. 4-11).

This water soft path case study examines the innovative water strategy planning process used in York Region, Ontario. In 2011, York Region set a forward-looking target of No New Water and is, to the authors’ knowledge, the first community in North America to explicitly approach its water strategy planning process from a soft path perspective. This case study marks the first investigation into the successes and challenges of putting soft path principles into practice.
The soft path pilot project for Fergus-Elora was initiated by the Grand River Conservation Authority (GRCA) in partnership with the POLIS Project on Ecological Governance, the Township of Centre Wellington (TCW), the Elora Environment Centre, and the University of Waterloo.
In Fergus-Elora, population and water use are expected to double between 2008 and 2040. The region is dependent on groundwater and if no conservation measures are taken the existing groundwater supply will likely require expansion by 2028.
The recommended approach for Fergus-Elora is to “use the same water tomorrow we use today,” which accommodates all future population and economic growth to 2040, and beyond, using the same amount of water used in 2008.

A 2010 report summarizing the results and analysis of a GRCA residential water use survey for Fergus-Elora is also provided. The survey focused on the usage of water-using fixtures and appliances, as well as water conservation efforts made by residents in the community.
This Soft Path Strategy for Salt Spring Island was developed by the Water Sustainability Project team in collaboration with the Salt Spring Island Water Council. Salt Spring is the largest and most populous of the Gulf Islands and has a year round population of approximately 10,000 which doubles during the summer with tourists and temporary residents. Water supply and quality are issues on parts of Salt Spring, with some drinking water lakes being close to their capacity to meet current demand and future commitments for additional supply, and difficulties with private wells particularly on the north end of the island.
This strategy offers direction to Salt Spring's growing water use by recommending a commitment to “preserving water supplies for the next generation.”
This case study investigates the water supply contexts and water conservation programs of three large cities in California: Los Angeles, San Francisco and San Diego. It is part of ongoing efforts by the Water Sustainability Project to highlight communities that are incorporating comprehensive demand management and “new water infrastructure” into their water management programs. Each city faces both growing populations and mounting water scarcity due to climate changes, new regulations and environmental concerns. Though they developed as cities in part thanks to supply-side approaches, each is now applying elements of the water soft path approach to address concerns about future water supplies.
This Soft Path Strategy for the City of Abbotsford and District of Mission was developed by the Water Sustainability Project team in consultation with Abbotsford Mission Water and Sewer Commission (AMWSC) staff beginning in December 2008. Heavy growth has increasingly strained the region’s water supplies, forcing the AMWSC to choose to either build costly infrastructure or to defer a need for new infrastructure by engaging in long-term water conservation planning.
The Strategy seeks to provide direction to this second option by recommending a commitment to “preserving water supplies for the next generation.”
This case study is a “real world” application of the soft path concept for the Town of Oliver in the Okanagan Basin, British Columbia. In this semi-arid area, the “myth of water abundance” remains firmly entrenched even though the region’s water supplies and aquatic ecosystems are under stress. Fortunately, a new paradigm of water management is emerging—an approach focused primarily on water conservation and efficiency, with the potential to ensure long-term sustainability and social and economic prosperity. This report provides an overview of the soft path approach, an analysis of three potential scenarios in the Okanagan, and recommendations for the community to take steps towards developing a sustainable approach to water management.
This handbook outlines the problems with conventional stormwater management and examines solutions for moving toward sustainability. It provides a comprehensive blueprint that outlines the crucial steps necessary to change the way communities manage and, importantly, govern stormwater. A main focus is addressing the fragmented responsibility for fresh water across and within jurisdictions—one of the greatest challenges to reinventing rainwater management.
This handbook was developed in partnership with the Environmental Law Centre (ELC) at the University of Victoria and is based on the ELC's 2010 report Re-inventing Rainwater Management: A Strategy to Protect Health and Restore Nature in the Captical Region.

Making the Most of the Water We Have is the first book to comprehensively present and apply the water soft path approach. Edited by the POLIS Project on Ecological Governance’s David B. Brooks and Oliver M. Brandes, and environmental consultant Stephen Gurman, it compiles the writings of more than 20 water scientists, policy advisors and analysts, and political ecologists. The publication focuses on detailed Canadian studies, and also takes a global perspective by looking at examples and experiences from around the world. Making the Most of the Water We Have demonstrates that soft path analyses are both analytical and practical, and emphasizes that soft paths are not only conceptually attractive, but can also be economically and politically feasible.
First published in June 2009, the paperback edition was released in March 2011. It is available at Chapters and Amazon, and can be purchased directly from the publisher for 20% off the list price.

The Soft Path for Water in a Nutshell provides an overview of the steps involved in soft path planning, illustrates how soft path planning differs from conventional supply-side management, and discusses the potential for this innovative approach to develop water sustainability in Canada. Originally published in November 2005, a revised and updated version was released in September 2007.
This handbook provides a practical resource on how individuals, utilities, and, most importantly, communities can save water and money. Designed for community leaders, water managers, and policy makers, this handbook seeks to inspire and facilitate action. It promotes an expanded definition of "urban water infrastructure" that includes innovative physical components, water sensitive urban design, and conservation programs designed to complement existing water supply networks.
This report focuses on identifying benefits as well as the barriers to water demand-side management in Canada. The interconnected and interrelated nature of barriers creates a gridlock that resists the adoption of a comprehensive approach to demand management for urban water in Canada. The report exaplains why a comprehensive and long-term approach to demand-side management is necessary and provides action plans for all levels of government and other stakeholders for implementation.
Urban water management poses many logistical and financial challenges in Canadian communities. By increasing water use efficiency, Demand Side Management can mitigate many of the impacts of human water use on overstretched municipal infrastructure and overstressed aquatic systems. Despite these benefits, Demand Side Management is seriously underutilized in Canada. What the Experts Think draws on interviews with Canadian experts in the field of water resource management and initiates a national network of water demand management practitioners.
The majority of Canadians live in large urban and regional centres, and municipal water use represents a significant portion (12 percent) of overall water withdrawals in Canada. Urban users in Canada use more than twice as much water as their European counterparts, with significant levels of wastage and inefficiency. Such high levels of urban water use have resulted in expensive supply and disposal infrastructure expansions, ecological impacts in developed areas where environmental stresses are already high, and increasing pressure on water treatment facilities to treat all water to drinking quality standards. Demand-side management (DSM) is an alternative (or, more accurately, complementary) approach to increasing supply infrastructure. It involves decreasing the demand for water through a mix of education, technology, pricing reform, regulation and recycling. This report provides insight into water use and supply in Canadian cities and the potential for demand side management.
