Management of Groundwater
In Texas, groundwater ownership rights are subject to regulation and control by the courts and the State Legislature. Groundwater may be managed individually by landowners under the rule of capture, or collectively by landowners and groundwater conservation districts.
- Rule of capture: Landowners are allowed to pump as much water as they choose, without liability to surrounding landowners who might claim that the pumping has depleted their wells. There are very few judicial or legislative restrictions to the rule of capture.
- Groundwater Conservation Districts: The creation of Groundwater Conservation Districts (GCDs) is authorized by state law (Texas Water Code, Chapter 36) and such districts are empowered and charged to conserve, preserve, protect, recharge, and prevent waste of groundwater resources within their boundaries. Groundwater conservation districts are the state's preferred method of groundwater management.
Groundwater conservation districts may be created by one of four methods:
- special legislative act,
- landowner petition process to the Texas Commission on Environmental Quality (TCEQ),
- landowner petition process to join an existing GCD, or
- TCEQ initiative in a Priority Groundwater Management Area (PGMA).
State Agency Roles
TCEQ may administratively create a GCD in response to a landowner petition only if the proposed area is included in a groundwater management area. A groundwater management area is an area delineated and designated by the Texas Water Development Board that is suitable for the management of groundwater resources. A priority groundwater management area is an area that, after extensive public participation and scientific study, is delineated and designated by the TCEQ because critical groundwater problems exist or will exist within a 50-year planning horizon. Landowners are required to create a groundwater conservation district when the TCEQ designates an area as a PGMA; however, if landowners do not take such action, TCEQ is mandated to do so (Texas Water Code, Chapter 35).
