Azle sits in the far northwestern corner of Tarrant County, one of the few spots in the county with limited Trinity outcrop. That makes wells here generally shallower and more practical than in the urban core or eastern Tarrant. Most residents inside the city limits are on municipal water, but the acreage and lake-area properties around Eagle Mountain Lake still use private wells.

Wells around Azle target the Trinity aquifer. Up high is the Paluxy Formation, a sand-dominant unit that lies at or near the surface in this northwest corner and deepens eastward toward about 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. Because depth increases west to east, a parcel on the western edge of the area is usually a shallower, simpler job than one farther in.

Tarrant County Permit Requirements

Water wells in Azle 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 Azle or northwest Tarrant County.

Frequently Asked Questions

Are homes in Azle on city water or private wells?
Inside the Azle city limits most homes are on municipal water. The private-well usage is on the acreage and lake-area properties in far northwestern Tarrant County, around Eagle Mountain Lake and out toward the Parker County line. If your tract sits outside a water-supply line, a well is often the practical option.
What aquifer do wells near Azle tap into?
The Trinity aquifer. Azle sits in the far northwestern corner of Tarrant County, one of the few areas with limited Trinity outcrop, so the Paluxy sand can be at or near the surface here. Below it, separated by the Glen Rose limestone, are the deeper Twin Mountains sands — the most productive Trinity unit.
How deep do wells go around Azle?
It varies with target and location, and Trinity depths increase from west to east across Tarrant County. In the northwest corner the Paluxy runs from at or near surface down toward about 1,000 feet, and the Twin Mountains sands sit roughly 500 to 2,000 feet. We estimate your likely depth from nearby driller's logs before quoting.
Do I need a permit to drill a well in Tarrant County?
Tarrant County is covered by the Northern Trinity Groundwater Conservation District (NTGCD). A typical domestic household well producing under 17.36 gallons per minute is exempt from permitting, metering, and fees — but every well drilled in the county must still be registered with the district. Larger, non-exempt wells require a permit before drilling. We handle the registration and any permitting.
What is the water quality like in Azle-area wells?
Trinity water in northwestern Tarrant County is generally good and stays fresh to roughly 1,500 feet of well depth. It is typically hard, so most homeowners run a softener. The Woodbine — which is poorer and higher in iron — is an eastern-Tarrant unit and is not the target out here. A post-drilling water test confirms what your specific well needs.
What does it cost to drill a well near Azle?
Cost depends on completion depth, casing, and which Trinity sand you finish in. Because the northwest corner is shallower than the rest of the county, wells here are often more practical. We give a free written estimate after reviewing your parcel and nearby logs.
How long does a well last in the Azle area?
A well that is properly constructed and maintained can last for decades. The pump and pressure tank are the parts that wear out and get replaced over time. Regular checks keep small problems from becoming dry-faucet emergencies.
Can DFW Well Service repair my pump in Azle?
Yes. Azle and northwestern Tarrant County are in our service area. Call (940) 536-8560 and describe the symptoms — no water, low pressure, or a pump that will not stop cycling — and we will get a technician out.
