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

Wells around Rio Vista draw mainly from the Trinity aquifer, with the Woodbine as a minor secondary source in parts of the county. Rio Vista sits in south-central Johnson County, on the western side of the county’s east/west aquifer split, where the Trinity sands run nearer the surface than in eastern Johnson. The Trinity’s upper Paluxy sand and the deep basal sands (which Prairielands GCD calls the Hensell and Hosston, the same units known as the Twin Mountains farther north) are the primary water source; between them sits the Glen Rose Formation, mostly limestone that holds little water and seals the sand below rather than producing from it.

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.

Frequently Asked Questions

Which groundwater district covers Rio Vista?
Rio Vista 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 Rio Vista, TX?
Wells in Rio Vista 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 Rio Vista?
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. Rio Vista is in south-central Johnson County, on the western side of the county's east/west split, where the Trinity runs nearer the surface than in eastern Johnson.
Is Rio Vista good rural well country?
Yes. The countryside around Rio Vista, along the Nolan River south of Cleburne, is rural-residential and agricultural land where private wells are the backbone of water supply. We're equipped to drill domestic, stock, and irrigation wells throughout the area and are familiar with the demands of rural water systems.
What does well drilling cost near Rio Vista?
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 Rio Vista?
Yes. We serve the Rio Vista 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 Rio Vista salty or brackish?
Mostly fresh. Western and south-central Johnson County around Rio Vista draws fresh Trinity at or near the surface. 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.
