Check the well rules before buying in western Hays County

A new well in western Hays County starts with district forms. Some home and stock wells do not need an operating permit if they stay within set limits. Larger wells and other nonexempt wells need a permit to pump.

Special zones cover Jacob's Well and parts of the Blanco River valley. A zone may change how a nonexempt well is built or how much it may pump in a drought.

Do not rely only on a seller's well story. Check the district map, well record, aquifer, and zone. Then read the live drought page. A drought stage or permit pause can change.
