Tex. Spec. Dist. Local Laws Code § 21.005

The district's powers and duties are subject to the state policy of encouraging the development and use of integrated area-wide waste collection, treatment, and disposal systems to serve the waste disposal needs of this state's residents, if integrated systems can reasonably be provided for an area, so as to avoid the economic burden on residents and the impact on state water quality caused by the construction and operation of numerous small waste collection, treatment, and disposal facilities.
