The Texas Alliance of Groundwater Districts (TAGD), formerly the Texas Groundwater Conservation Districts Association, was formed on May 12, 1988. Its voting membership is restricted to underground water conservation districts of Texas who have the powers and duties to manage groundwater as defined in Chapter 36 of the Texas Water Code. TAGD is organized exclusively for charitable, educational, or scientific purposes within the meaning of Section 501(c)(3) of the Internal Revenue Code.

The Alliance was formed to further the purpose of groundwater conservation and protection activities. The Alliance also provides a means of communication and exchange of information between individual districts regarding the day-to-day operation of local groundwater management. Members of TAGD are part of a network in which valuable technical and operational experience is available. This often provides information that saves districts time and money. The Alliance maintains contact with members of the private sector and various elected, local, state, and federal officials, providing them with timely information on activities and issues relevant to groundwater management. Members of TAGD also serve on various local, state, and federal agency committees and subcommittees, providing input and information on behalf of the member district.

The Alliance urges any nonmember Groundwater Conservation District to become Members. In addition, TAGD also encourages other entities with an interest in groundwater to become Associate Members. Your memberships benefit Groundwater Conservation Districts and the Public by furthering the policies and goals of the Alliance.
