Haslet sits on the far north edge of Tarrant County, one of the parts of the county that has kept its larger-lot and acreage character even as growth arrives. Newer subdivisions are on municipal water, but the semi-rural tracts around town still use private wells. It is worth being clear about the geology: the limited Trinity outcrop in Tarrant County is confined to the far northwestern corner, and under the Haslet area the Trinity is deep and confined.
Wells here target the Trinity aquifer. Up high is the Paluxy Formation, a sand-dominant unit that lies at or near the surface only in the far northwest corner and deepens toward the east — countywide the Paluxy runs from surface to roughly 1,000 feet. Beneath it, separated by the Glen Rose limestone — which acts as a confining layer here, not a producer — are the Twin Mountains sands, the most productive Trinity unit, sitting roughly 500 to 2,000 feet and also deepening eastward. In the eastern Tarrant suburbs a minor Woodbine aquifer supplies some household and livestock water, but its yields are lower and its water poorer than the Trinity.
Tarrant County Permit Requirements
Water wells in Haslet and Tarrant County fall under the Northern Trinity Groundwater Conservation District (NTGCD), a single-county district created in 2007. A typical domestic household well — one not capable of producing more than 17.36 gallons per minute and used for household, livestock, or agricultural purposes — is exempt from permitting, metering, and production fees. Even so, every well drilled in the county must still be registered with the district. Larger, non-exempt wells require a permit before drilling. Our guide to Tarrant County water well regulations walks through the full process.
DFW Well Service handles the NTGCD registration and any permitting as part of your project. Call (940) 536-8560 for a free estimate on a new well or any pump and service work in Haslet or anywhere in Tarrant County.
