Partnership Approaches to Multi-Benefit Solutions : Pulling Up Chairs and Getting Stuff Done

A discussion that will explore multi-stakeholder approaches to resolving urban and rural water challenges. The panel will present examples of collaboration to equitably resolve conflicts with multi-benefit solutions for both human and ecological communities. There will be a discussion about collaborations and partnerships as an effective approach to resolving multi-party resource conflicts in an era of increasing urgency due to drought, climate change and resource insecurity.

- Michael Garrity will introduce the Yakima Basin Integrated Plan, highlighting the significance of resource allocation problems and collaborative efforts to resolve them through land purchases, irrigation infrastructure retrofit, reservoir management changes and other projects.
- Christine Alford will discuss collaborative efforts to improve agricultural and urban water systems and use in two coastal creek watersheds. Her multi-stakeholder effort engages rural landowners in effort to reduce water withdrawals and restore flows, while also prioritizing municipal water conservation and infrastructure enhancements.
- Amy McCoy will contribute economic expertise and insights throughout the program and discuss her work in Tucson's example of determining the economic value of water management strategies, including conservation programs and community benefits from utilizing multiple sources of water (e.g. rainwater, graywater, stormwater, etc.) and the importance this can have as a policy shaping tool

Assessing Climate Risks and Implementing Adaptation at Large Utilities - Case Studies with EPA's Climate Resilience Evaluation and Awareness Tool

Drinking water and wastewater utilities face many challenges due to changes in climate and resulting impacts on water resources. EPA's Climate Ready Water Utilities (CRWU) provides resources to help the water sector adapt to climate change impacts by promoting a clear understanding of climate science and adaptation options. Among its suite of tools, the Climate Resilience Evaluation and Awareness Tool (CREAT) provides local climate projection data within a risk assessment framework to help utilities assess climate impacts and consider adaptation measures to increase utility resilience. Both the initial development of CREAT, as well as subsequent versions, were guided by a Working Group composed of water utilities, associations and federal partners. Among its early adopters, East Bay Municipal Utility District (EBMUD) in Oakland, California and Southern Nevada Water Authority (SNWA) in Las Vegas, Nevada have used CREAT to conduct climate assessments. EBMUD has been involved with the development and testing of CREAT since the first version of the tool was released in 2010 to help quantify and communicate the risk of climate change on its operations. Using 2060 temperature, sea level rise and precipitation projections, a climate change risk assessment was performed which highlighted the impacts to water demand, customer rationing, flood control and water supply, with changes in precipitation posing the greatest risk. Information from the analysis was used in the development of EBMUD's Climate Change Monitoring and Response Plan which summarized the impacts and identified adaptation and mitigation strategies including the use of supplemental water supplies, increased conservation and water recycling, and reducing greenhouse gas emissions. Like EBMUD, SNWA tested the early versions of CREAT and provided feedback on improvements. Most recently, SNWA collaborated with the EPA to pilot CREAT version 2.0 to produce a climate change risk assessment. SNWA participants considered impacts across three potential climate scenarios, based on the projections provided within CREAT. Assessments considered both short and long term impacts, using climate projections for two future time periods (2035 and 2060). Situated in the desert, SNWA has historically been most vulnerable to persistent drought in the Colorado River basin, which provides 90 per cent of their supply. SNWA withdraws this water from Lake Mead. The risk assessment process found that without adaptive action, future warming would likely worsen drought conditions, and lead to low Lake Mead levels that could trigger a reduction in supplies, but also create major operational challenges with SNWA's intake systems, water treatment systems, and distribution system. The SNWA team developed a number of planned actions including Colorado River system-wide conservation, construction of a third intake pump station, and addition of aerators in covered reservoirs in the distribution system to address the impacts associated with worsening drought. These measures will reduce the risk to supplies and infrastructure presented by low reservoir levels, and make SNWA "climate ready". EBMUD and SNWA are currently participating in the CREAT 3.0 Working Group, helping to guide the development of the next version of CREAT (planned for release Summer 2015).

Water is the lifeline of American prosperity. It keeps our communities healthy, our cities running, and our economies growing. One-fifth of the U.S. economy would grind to a halt without a reliable and clean supply of water. After working around the clock for more than a century, these systems are aging and failing. Yet, our nation's water infrastructure is largely out of sight, and out of mind for most Americans. This session will feature leaders from the public and private sector discussing local and national efforts to elevate the importance of water infrastructure in America.
