In 1988, AWWA brought Drinking Water Week to the attention of the U.S. Government and formed a coalition along with the League of Women Voters, the Association of State Drinking Water Administrators and the US Environmental Protection Agency.
Rep. Robert Roe and Sen. Dennis DeConcini subsequently sponsored a resolution to name the first week of May as Drinking Water Week, and the week-long observance was declared in a joint congressional resolution signed by then President Ronald Reagan.
