Water Utility Climate Alliance


In support of our mission to enhance the usefulness of climate science for the adaptation community and improve water management decision-making in the face of climate uncertainty, we’ve undertaken the following activities.

Federal Activities

In his 2013 State of the Union address, President Barack Obama said "we must do more to combat climate change" and that he will develop executive actions to "prepare our communities for the consequences of climate change." We appreciate the president's emphasis on preparedness and adaptation, and agree that we must do more. Adapting to the threat of climate change deserves focused national attention.

In June, 2013, President Obama followed up his commitment in his State of the Union to "do more" by releasing a Climate Action Plan that includes a major section on preparing the United States for the impacts of climate change, as well as sections on cutting carbon pollution and leading international efforts to address climate change. The Water Utility Climate Alliance (WUCA) has responded to several federal agency climate adaptation plans, including the Department of Commerce and EPA, to emphasize the need for collaboration and information-sharing between the federal government and water utilities around climate adaptation.

Past WUCA Chair Paul Fleming also has participated in the National Climate Assessment process as a member of the National Climate Assessment and Development Advisory Committee (NCADAC), and as a Convening Lead Author of the Water Resources Chapter and as a Lead Author on the adaptation chapter. In addition, WUCA has provided technical inputs to the NCA and commented on the public review draft.

Piloting Utility Modeling Applications (PUMA)

WUCA is developing partnerships with the climate science community, continuing to provide feedback on climate change research and data and encouraging additional climate change research on a regional and sub-regional basis through projects like Piloting Utility Modeling Applications (PUMA).

PUMA is a collaborative venture bringing together WUCA members, Regional Integrated Sciences and Assessments (RISA) leaders, and selected representatives of the climate science and applications community.

Creating Resilient Water Utilities Webinar

In 2013, WUCA coordinated with the EPA's Creating Resilient Water Utilities (CRWU) Initiative to present a webinar series on water utility adaptation planning and decision-making. The webinar included presentations by utility representatives on scenario planning, robust planning and threshold analysis. Learn more on the CRWU website.
