Guam Waterworks Authority

The local public water responsibility predecessor for PUAG originated June 30, 1950 when the Congress of Guam Passed Public Law 1-12, which gave the Department of Public Works the authority to administer all utility services. In response to increased water demand and a need to expand utility services, the 1st Guam Legislature passed Public Law 1-88 on June 6, 1952 that created a new entity called the Public Utility Agency of Guam. PUAG consisted of the telephone, power, water and wastewater utilities.

On July 31, 1996, Public law 23-119 established the Guam Waterworks Authority to be a semi autonomous, self-supporting agency. GWA officially obtained its status on February 1, 1997.
