Wells around Ferris draw mainly from the Woodbine, the primary residential aquifer across Ellis County, with the deeper Trinity as a secondary target far below it. Ellis County sits on Austin Chalk and Eagle Ford bedrock, and the Trinity is present only at substantial depth countywide. The Woodbine has a regional thickness of roughly 100–1,400 feet; the deeper Trinity sands (the Twin Mountains and Paluxy) reach roughly 2,000–3,000 feet down in southeastern Ellis County — not the few-hundred-foot range you’d see in the outcrop counties to the west. Ferris sits in northern Ellis County, closer to the recharge side than Ennis or the far southeast, so both depth and mineralization tend to run somewhat lower here.

Drilling rates in Ellis County typically run $32–$45 per foot. Trinity completions can be substantially deeper than Woodbine completions and project cost varies accordingly.

Ellis County Permit Requirements

All new wells in Ellis County require a permit through the Prairielands Groundwater Conservation District before drilling begins. The PGCD regulates well spacing, construction standards, and production for both exempt domestic wells and non-exempt production wells. For more detail on the county permitting process, see our guide to Ellis County water well regulations.

Frequently Asked Questions

How deep are water wells in the Ferris area?
There's no single typical depth across Ellis County — it varies meaningfully from one property to the next, so we review the driller's logs from neighboring wells and check public-water availability before quoting a project. The Woodbine is the main residential aquifer; the deeper Trinity sits well below it, with the Twin Mountains sand tapping out around 2,000–3,000 feet down in the southeastern part of the county. Ferris is in northern Ellis County, closer to the recharge side than Ennis, so depth and mineralization tend to run a bit lower here than farther downdip.
Does Ferris have a groundwater conservation district?
Yes. Ellis County falls within the Prairielands Groundwater Conservation District (PGCD). A permit is required before drilling a new well. DFW Well Service handles the permit application as part of our standard drilling process.
Can I drill a well within Ferris city limits?
Most properties within the Ferris city limits are served by municipal water. Private wells are more common on rural acreage outside city boundaries in unincorporated Ellis County. If your property is on the rural edge or on acreage, a well may be permitted. Contact us to discuss your specific parcel.
What does well drilling cost near Ferris?
Drilling rates in Ellis County typically run $32–$45 per foot depending on depth, formation hardness, and well diameter. Total cost depends on completion depth and the full system, and a deeper Trinity completion runs well above a shallower Woodbine one. We provide a free itemized written estimate after reviewing neighboring driller's logs for your parcel.
How long does it take to drill a well in Ferris?
Once permitting is complete, most residential wells can be drilled in one to two days. The full project from permit application to a functioning system with pump and pressure tank typically takes two to four weeks depending on Prairielands GCD processing times.
Do you service existing wells and pumps near Ferris?
Yes. We repair and replace submersible pumps, pressure tanks, well seals, and electrical components throughout Ellis County. If you have low water pressure, air in the lines, or a pump that won't run, call us for a diagnostic visit.
Is the well water in Ferris salty or brackish?
It varies across Ellis County. Texas Water Development Board data shows the Woodbine — the main aquifer — is fresher in the northwest and saltier toward the southeast, and most well water here exceeds the EPA's secondary 500 mg/L standard for total dissolved solids (a measure of how mineral-heavy the water is). Ferris sits in the northern part of the county, but a full water-quality test is still important and treatment is common.
