The mission of the Texas Water Development Board (TWDB) is to provide leadership, information, education, and support for planning, financial assistance, and outreach for the conservation and responsible development of water for Texas. Our mission is a vital part of Texas' overall vision and the state's mission and goals that relate to maintaining the viability of the state's natural resources, health, and economic development. To accomplish our goals of planning for the state's water resources and providing affordable water and wastewater services, the TWDB provides water planning, data collection and dissemination, financial assistance, and technical assistance services to the citizens of Texas. The tremendous population growth that the state continues to experience and the recurrent threat of severe drought only intensify the need for the TWDB to accomplish its goals in an effective and efficient manner. The Texas Water Development Board (TWDB) was created in 1957. It currently supports the development of regional water plans and incorporates them into a state water plan for the orderly and responsible development, management, and conservation of the state's water resources; provides loans to local governments for water supply projects; water quality projects, including wastewater treatment and nonpoint source pollution control; flood control projects; agricultural water conservation projects; rural and small community water and wastewater projects; and expenses related to administering groundwater conservation districts; provides grants and loans for the water and wastewater needs of the state's economically distressed areas; provides agricultural water conservation and water-related research and planning grants; conducts studies of the occurrence, quantity, quality, and availability of the state's surface water and groundwater; collects data and conducts studies concerning the freshwater needs of the state's bays and estuaries; and maintains a centralized data repository of information on the state's natural resources called the Texas Natural Resources Information System (TNRIS) and manages the Strategic Mapping (StratMap) Initiative.
