Project Summary
The Southern Nevada Water Authority – a cooperative of seven water and wastewater agencies – serves more than two million residents in Nevada, including the city of Las Vegas. The Water Authority worked with the U.S. Environmental Protection Agency's Creating Resilient Water Utilities program to conduct a vulnerability assessment of the Las Vegas service area that considered climate impacts and vulnerabilities in two future scenarios: in 2035 and in 2060. Projected climate impacts included hotter and drier summers, drought conditions and increased algal blooms.
This vulnerability assessment also helped identify more than 60 potential current and future actions to take in response to and prepare for climate change. The Water Authority followed up this initial analysis with a more in-depth assessments of water source availability under future climate change, population and water demand projections. These assessments provide the Water Authority with a better understanding of its climate risks and potential vulnerabilities. The information also informs the water authority’s ultimate consideration, selection and implementation of appropriate adaptation strategies. The Water Authority continues to anticipate, prepare and plan for the future as a member of the Water Utility Climate Alliance, a consortium of 10 of the largest water utilities around the country actively engaged on climate change.
