Water Utility Climate Alliance

Water Utility Climate Alliance

Delivering reliable, high-quality water requires a delicate balance between water supplies and customer demands.

While water managers continually strive to maintain this supply-and-demand balance through long-term water resource planning and demand management, new challenges exist due to the impacts of climate change, putting the world's water resources at risk.

The Water Utility Climate Alliance (WUCA) is dedicated to enhancing climate change research and improving water management decision-making to ensure that water utilities will be positioned to respond to climate change and protect our water supplies.

      WUCA co-hosts "Creating Resilient Cities" forum in Austin, Texas

      Along with Austin Water and the City's Office of Sustainability, WUCA co-hosted a forum on creating resilient cities on May 2, 2018.

      Sessions explored the potential impacts of climate change and climate-related extremes on water utilities and offered examples of effective adaptation solutions from utilities around the nation.

        Planning for Sea Level Rise: An AGU Talk in the Form of a Co-Production Experiment Exploring Recent Science

        The Water Utility Climate Alliance first defined the term "actionable science" in 2009. We increasingly recommend that the best path to creating actionable science involves a "co-production" dynamic bringing together scientists and decision makers.

        This process was successfully employed by WUCA member David Behar recently, to develop a set of consensus statements regarding probabilistic projections of sea level rise with fellow decision makers and climate scientists. This white paper was presented at the American Geophysical Union Fall Meeting in New Orleans in December 2017.


Key messages from WUCA

  • Icon of thermometer

    Warming is here and now

    Climate adaptation planning is not just about the future. Water utilities are experiencing the effects of a changing climate on their water resources today.

  • Icon of pipe

    Know your system and explore its vulnerabilities

    Assess your water system to identify vulnerabilities. Risks can only be reduced if they are identified.

  • Icon of land surveyor looking through equipment

    Plan for multiple futures

    Predicting the future is not feasible but anticipating plausible warmer future climates is. Prepare to face a variety of scenarios.

  • Icon of man holding gears

    Capacity building and assessment are part of the adaptation equation

    Developing the technical and managerial expertise to identify and assess climate risks to a system is as much a part of adaptation as the steps taken to implement risk reduction measures.
