About us

In January 2007, the San Francisco Public Utilities Commission hosted the first national Water Utility Climate Change Summit, which was attended by more than 200 water and wastewater utility executives, government officials, climate change experts and environmental leaders. The purpose of the gathering was to help participants better understand the impacts of climate change on water-related infrastructure and water resource supplies.

Shortly after the summit, the Water Utility Climate Alliance (WUCA) was formed to provide leadership and collaboration on climate change issues affecting the country's water agencies. The organization comprises 12 of the nation's largest water providers. WUCA members supply drinking water for more than 50 million people throughout the United States.
