Drilling a Water Well in Trinity County: No Local Groundwater District
Trinity County has no local groundwater conservation district. That means fewer local permit rules for private wells, but also less local oversight of the water supply.
Many Texas counties have a groundwater conservation district (GCD). A GCD is a local agency that requires permits before you drill a well. It also tracks how much water is pumped. Trinity County does not have one. You do not need a local permit to drill a private water well here. But you also have fewer local protections if a neighbor or business pumps heavily from the same underground water source.
State rules still apply. Any licensed well driller must follow Texas Department of Licensing and Regulation rules. The well must also be registered with the Texas Water Development Board's groundwater database. Trinity County sits over underground aquifer formations that supply water to private wells in the area. Before buying rural land that relies on a private well, test the water. Ask your driller about local well depth and how much water nearby wells produce. Contact the Texas Water Development Board (TWDB) for statewide well information.
