About National Water Supply Alliance

The NATIONAL WATER SUPPLY ALLIANCE is a national organization formed to advance the interests of water supply providers before the United States Congress and federal agencies whose actions impact water supply storage and projects. Our members include state, regional, and local governments, as well as wholesale water providers and utilities who rely on water supply stored in federal facilities maintained by the U.S. Army Corps of Engineers. NWSA was formed to give water supply providers across the nation a unified voice to advocate for the preservation and enhancement of the nation’s water supply, protection of traditional State authorities, and to ensure that water supply interests share equitably in the benefits provided by the U.S. Army Corps of Engineers.
