Tex. Water Code § 36.116

(a) In order to minimize as far as practicable the drawdown of the water table or the reduction of artesian pressure, to control subsidence, to prevent interference between wells, to prevent degradation of water quality, or to prevent waste, a district by rule may regulate:

(1) the spacing of water wells by:

(A) requiring all water wells to be spaced a certain distance from property lines or adjoining wells;

(B) requiring wells with a certain production capacity, pump size, or other characteristic related to the construction or operation of and production from a well to be spaced a certain distance from property lines or adjoining wells; or

(C) imposing spacing requirements adopted by the board; and

(2) the production of groundwater by:

(A) setting production limits on wells;

(B) limiting the amount of water produced based on acreage or tract size;

(C) limiting the amount of water that may be produced from a defined number of acres assigned to an authorized well site;

(D) limiting the maximum amount of water that may be produced on the basis of acre-feet per acre or gallons per minute per well site per acre;

(E) managed depletion; or

(F) any combination of the methods listed above in Paragraphs (A) through (E).

(b) In promulgating any rules limiting groundwater production, the district may preserve historic or existing use before the effective date of the rules to the maximum extent practicable consistent with the district's management plan under Section 36.1071 and as provided by Section 36.113.

(c) In regulating the production of groundwater based on tract size or acreage, a district may consider the service needs or service area of a retail public utility. For the purposes of this subsection, "retail public utility" shall have the meaning provided by Section 13.002.

(d) For better management of the groundwater resources located in a district or if a district determines that conditions in or use of an aquifer differ substantially from one geographic area of the district to another, the district may adopt different rules for:

(1) each aquifer, subdivision of an aquifer, or geologic strata located in whole or in part within the boundaries of the district; or

(2) each geographic area overlying an aquifer or subdivision of an aquifer located in whole or in part within the boundaries of the district.

(e) In regulating the production of groundwater under Subsection (a)(2), a district:

(1) shall select a method that is appropriate based on the hydrogeological conditions of the aquifer or aquifers in the district; and

(2) may limit the amount of water produced based on contiguous surface acreage.
