wateronline.com n Water Innovations 7 Keys To 'One Water' It's a buzzword for the industry, but what does it really entail? EDITOR'S LETTER By Kevin Westerling Chief Editor, editor@wateronline.com 6 T o illuminate and promote the idea of One Water, the US Water Alliance recently outlined seven characteristics common to the approach, defined as "managing all water in an integrated, inclusive, and sustainable manner to secure a bright, prosperous future for our children, our communities, and our country." Water Innovations supports the concept as well. For each of the seven "hallmarks of One Water" from the One Water Roadmap report (US Water Alliance, December 2016), there is a corresponding solution to be found in the "Top 10 Trends Of 2017" — an indicator that the One Water philosophy and water industry innovation go hand-in-hand. A mindset that all water has value. "All water can and must be managed carefully to maximize its benefit." The volume of water lost in the distribution system has become a focal point for municipalities in recent years, brought to the fore because of scarcity, economics, and continuously deteriorating pipes. But another reason for the attention is the newfound ability to detect leaks through tech- nological advances. Among the most impressive techniques is a noninvasive, satellite-based system that saves labor hours while also saving valuable water (see "'Far Out' Technology Simplifies Pipeline Leak Detection" ). A focus on achieving multiple benefits. "Design and implement programs with a focus on achieving multiple benefits — economic, environ- mental, and social." You may already be familiar with the "triple bottom line" approach to sustainable development, a framework that considers the three Ps — profit, people, and planet — and is very compatible with One Water. Environmental impact bonds, described in "Financing Infrastructure Through Environmental Impact," have the triple bottom line baked into the investment, with financial risk that is shared and therefore minimized. A systems approach. "Tackle problems based on the complete lifecycle of water and larger infrastructure systems — rather than limiting our- selves to one piece of the equation." Water reuse can happen at various stages of the water cycle and can be executed by various players (industrial, municipal, on-site). Shortening the typical route from wastewater to useful water expands supply and preserves infrastructure, bringing immediate value to practitioners and long-term benefits to the industry at large (see "Stepping Up Water Reuse — From Irrigation To Direct-Potable" ). Watershed-scale thinking and action. "Communities must reconcile their water demands with the imperative to sustain the resource for future generations." Watersheds are shared, and thus it is a shared responsibility to keep them clean. For wastewater treatment plants (WWTP), it's imperative that they stay ahead of potential threats. Understanding risk can help prevent pollution events, mitigate those that occur, and justify infrastructure investment. To help, "A Comprehensive Software Tool For Assessing Risk At Wastewater Treatment Plants" has been introduced. Right-sized solutions. "Focus on the appropriate scale of intervention to achieve the desired outcome." WWTPs serving large cities with ample budgets can afford big, expensive improvements, but sometimes smaller-scale solutions are more sensible and cost-effective. There are also times when a small utility with limited resources needs a big fix. While the One Water philosophy can be applied at any scale, the utility and the public are best served when solutions are "right-sized" to efficiently meet the objective. "A Small Utility's Path To Climate Change Readiness" is a case in point. Partnerships for progress. "Recognize that all sectors are part of the solution to a water-secure future." Protecting our water supply is a group effort — it takes many hands to achieve it, or just a few to spoil it. Water stakeholders across the board can align capabilities for mutual benefit while also serving the One Water initiative. For example, the Water Research Foundation co-funded a project with Halifax Water in Nova Scotia that makes water treatment more sustainable, with excellent prospects for wide-scale implementation (see "In-Line Turbines Harness Energy For Water Utilities" ). Inclusion and engagement of all. "Leverage investments in water systems and water resources to build stronger communities, a clean environ- ment, and thriving local economies for all." Water connects us all, and water and wastewater utilities, as caretakers of this precious resource, are inextricably bound to the community at large. Sadly, this bond often goes unacknowledged beyond the surface-level relationship of service provider-to-customer, amounting to missed opportunity. Not so in Chicago, where the wastewater utility turned a one-time nuisance ("sludge") into a literal growth opportunity, detailed in "Evolving From Controlled Biosolids Distribution To Revenue-Generating Compost" . There is much more to the One Water story, of course. It is a cyclical, never-ending journey, like that of water itself. The One Water goal, as with Water Innovations, is to help guide your way.
