Hundreds of data center developments across Texas are under investigation after failing to report their water use, according to the Texas Attorney General’s Office. The facilities did not respond to a survey from the Texas Water Development Board, the state agency responsible for monitoring groundwater and surface-water use. The investigation comes as Texas continues to attract large-scale data center projects that support cloud computing and artificial intelligence but can place additional demands on local water and power systems. The data centers identified by state officials are located in 18 counties: Harris, Montgomery, Travis, Dallas, Tarrant, Smith, Bexar, Tom Green, Potter, Randall, Lubbock, Midland, Ector, Wichita, Victoria, Brazos, Nueces and El Paso. The missing responses leave state and local officials with less information about how much water individual facilities use and where that demand is concentrated. That information is increasingly important for communities planning amid population growth, drought risk and competing demands on groundwater and surface-water supplies. The Texas Water Development Board’s survey is part of the state’s effort to track water use across Texas. The investigation’s findings and any potential enforcement actions were not detailed in the available information.
