The EUWCD strictly prohibits the waste of groundwater. Waste includes actions such as producing water without beneficial use, allowing water to escape into other aquifers or onto land, polluting aquifers, or letting irrigation tailwater flow onto neighboring properties without permission. All well owners and operators must take precautions to prevent waste and protect groundwater quality. The District may issue enforcement orders to stop waste or pollution and may take emergency action when necessary​. Please refer to our district rules here.

Yes, groundwater may be transported outside of the District, but it requires a Transport Permit issued by EUWCD. Applications for groundwater export are reviewed to ensure compliance with the District’s rules, including volume limits, beneficial use, and impact on local aquifer conditions. All transport permits are subject to conditions set by the Board and must not interfere with the District’s management goals​. Please refer to our district rules here and view our fee schedule here.

Modeled Available Groundwater (MAG) is the amount of groundwater that can be pumped annually, on average, without exceeding the Desired Future Conditions (DFCs) for an aquifer. MAG is established by the Texas Water Development Board using groundwater availability models. EUWCD uses MAG to evaluate permit applications and to ensure that cumulative groundwater withdrawals remain within sustainable limits set by state planning efforts in Groundwater Management Areas 13 and 15​.
