Water Well Drilling & Pump Repair in Alvarado, TX | DFW Well Service

Service Area Overview

Licensed well drilling and pump service in Alvarado and north-central Johnson County under Prairielands GCD; Trinity primary, Woodbine secondary.

DFW Well Service provides water well drilling, pump repair, and inspection services in Alvarado and throughout Johnson County. Alvarado sits along I-35W in north-central Johnson County, a growing community where new suburban development and established rural acreage exist side by side. Many properties on the city’s rural fringes and in unincorporated Johnson County still depend on private wells, and that’s where we come in.

Johnson County overview → Permit & regulations → TDLR License #61234 DKMPW Updated August 6, 2026

Wells around Alvarado draw mainly from the Trinity aquifer, with the Woodbine as a minor secondary source in parts of the county. Alvarado is in north-central Johnson County, in the transition zone of the county’s east/west split: the Trinity sands — the Paluxy on top, the Glen Rose limestone in the middle, and the deep basal sands (which Prairielands GCD calls the Hensell and Hosston, the same units known as the Twin Mountains farther north) — sit under a cover of Eagle Ford shale and Austin Chalk that thickens toward the east. There’s no single typical depth across Johnson County; it varies meaningfully by parcel and by which layer the well targets.

Drilling rates in Johnson County run $32–$50 per foot, with formation hardness and depth determining where your project falls in that range.

Johnson County Permit Requirements

New wells in Johnson County require a pre-drilling permit through the Prairielands Groundwater Conservation District (PGCD), which covers Ellis, Hill, Johnson, and Somervell counties. The district enforces spacing and setback rules and requires a completion report with driller’s log after the well is finished. For a complete overview, see our guide to Johnson County water well regulations.

DFW Well Service (TDLR License #61234 DKMPW) serves Alvarado and all of Johnson County for well drilling and pump service. Call (940) 536-8560 for a free estimate.

Frequently Asked Questions

Which groundwater district covers Alvarado?
Alvarado and all of Johnson County fall within the Prairielands Groundwater Conservation District (PGCD), which manages groundwater for Ellis, Hill, Johnson, and Somervell counties. A permit is required before drilling a new well. DFW Well Service submits the permit application on your behalf as part of our standard process.
What formations supply well water in Alvarado, TX?
Wells in Alvarado draw mainly from the Trinity aquifer — the upper Paluxy sand and the deeper basal sands (which Prairielands GCD calls the Hensell and Hosston, the same units known as the Twin Mountains farther north) — plus the Woodbine in places as a minor source. Between the Paluxy and those basal sands sits the Glen Rose Formation, mostly limestone that holds little water and seals the sand below rather than producing from it.
How deep are wells near Alvarado?
There's no single typical depth across Johnson County — it varies meaningfully from one parcel to the next, so we review the driller's logs from neighboring wells before recommending a target depth. Alvarado is in north-central Johnson County, in a transition zone where Eagle Ford shale and Austin Chalk cover thickens toward the east, so the Trinity lies deeper here than in western Johnson.
Is Alvarado served by city water, or do properties use wells?
Both. The incorporated parts of Alvarado are largely on municipal water, but Alvarado is a growing community, and many properties on the rural fringes, in unincorporated Johnson County, and on larger acreage tracts rely on private wells. If your property is outside the city water service boundary, a private well may be your best long-term water option.
What does well drilling cost near Alvarado?
Johnson County drilling rates run $32–$50 per foot. Final cost depends on completion depth, casing, pump, and pressure equipment. We provide a free itemized written estimate after reviewing neighboring driller's logs for your parcel.
Can you service a well pump on short notice in Alvarado?
Yes. We serve the Alvarado area for pump repair, pressure tank replacement, and well service calls. If your well has lost pressure, the pump is cycling rapidly, or you're getting no water at all, call (940) 536-8560 — we carry common pump sizes and parts on our service trucks and can often resolve issues in a single visit.
Is the well water in Alvarado salty or brackish?
Mostly fresh, but test to be sure. Johnson County draws fresh Trinity at or near the surface in the west, but Alvarado sits toward the county's central/eastern side. The Texas Water Development Board flags localized salty pockets in the Woodbine outcrop (from natural sulfate) and notes the deep lower Trinity under Johnson County is largely non-fresh, so deeper or eastern wells warrant a full test for total dissolved solids — a measure of how mineral-heavy the water is — and sulfate.
