Water: Climate

Climate Ready Water Utilities (CRWU)


EPA's Climate Ready Water Utilities (CRWU) initiative assists the water sector, which includes drinking water, wastewater, and stormwater utilities, in addressing climate change impacts. Through the development of practical and easy-to-use tools, EPA promotes a clear understanding of climate science and adaptation options by translating complex climate projections into accessible formats. This information helps utility owners and operators better prepare their systems for the impacts of climate change.

Extreme weather events, sea level rise, shifting precipitation patterns and temperature variability, all intensified by climate change, have significant implications for the sustainability of the water sector. By planning for, assessing and adapting to these challenges, the water sector can fulfill their public health and environmental missions and begin the process of becoming climate ready. Take a look at our "Becoming Climate Ready"Exit EPA Disclaimer video on what it means to be Climate Ready.

These utilities and thousands more across the nation are experiencing the impacts of climate change and extreme weather events. Many are taking action now to reduce their vulnerability and increase their resilience to a changing climate. In 2015, EPA partnered with and assisted over 20 communities as they completed their first climate risk assessment using EPA’s Climate Evaluation and Awareness Tool (CREAT).

Water Utility Climate Resilience Support Projects
EPA is supporting more than 20 comprehensive climate-related risk assessments for drinking water and wastewater utilities using our Climate Resilience Evaluation and Awareness Tool. The Agency will provide technical assessment assistance to the participating utilities, which will help identify adaptation strategies for implementation to bolster climate readiness and resilience.

Climate Ready Water Utilities
Climate Resilience Evaluation and Awareness Tool

This software tool assists drinking water and wastewater utility owners and operators in understanding potential climate change impacts and in assessing the related risks at their utilities. CREAT allows users to evaluate potential impacts of climate change on their utility and to evaluate adaptive options to address these impacts using both traditional risk assessment and scenario-based decision making.

Sustainability and Adaptation
An introduction to the CRWU initiative and climate change adaptation planning.
The recently updated CRWU Adaptation Strategies Guide highlights strategies for pursuing both adaptation and sustainability goals, specifically those related to green infrastructure and energy management. This webinar will provide an in depth look at the new sustainability information in the Guide and utility representatives will share their experience planning and implementing sustainable strategies.
Sustainability and Adaptation Webinar (1:03:32 mins)


Scenario Planning to Support Decision Making
Many utilities are thinking critically about how to best manage water resources and utility assets when future conditions are uncertain. This session will introduce scenario planning, a method that allows a flexible approach to strategic long-term planning and highlight examples from utility representatives that have used scenario planning.

Robust Planning to Support Decision Making
This webinar will present another option for strategic long-term planning, robust decision making, which assesses the trade-offs between different approaches and helps identify the most ‘robust’ solution. Utility representatives that have used robust decision making techniques will share their insights and experiences.
