Wells around Plano often draw from the deeper Trinity Group rather than the Woodbine, because Plano sits in western Collin County where the Woodbine sand thins out. Where the Woodbine is thin or absent, properties target the Trinity (Paluxy, Glen Rose, Twin Mountains) instead — and that sand sits substantially deeper than in central or eastern Collin County. Most of Plano is on city water, so private wells are less common here than in the more rural parts of the county. There’s no single typical depth here; it varies meaningfully by parcel and which layer the well targets.

Collin County Permit Requirements

Well construction in Plano and unincorporated Collin County is regulated by the North Texas Groundwater Conservation District. Property owners must obtain a well permit from the district prior to drilling, and all work must be performed by a TDLR-licensed driller. The district also enforces well spacing and property-boundary setbacks, while TDLR construction standards cover separation from septic systems and surface contamination sources. Learn more in our detailed guide to Collin County water well regulations.

Frequently Asked Questions

Are water wells common in Plano, TX?
Not especially. Plano is a large, built-out suburb in southwestern Collin County, and nearly every property is on municipal water. Private wells are the exception here, found mainly on the occasional larger acreage tract or in the unincorporated areas nearby, rather than on standard city lots.
How deep do wells typically go in the Plano area?
There's no single typical depth for the Plano area, and wells here can run deeper than in central or eastern Collin County, so we review the driller's logs from neighboring wells before quoting a project. Plano sits in western Collin County near the line where the Woodbine sand thins out: in parts of the western county the Woodbine is thin or absent, so wells target the deeper Trinity (Paluxy) sand instead, which sits substantially lower.
What is the drilling cost per foot in Collin County?
Typical rates in Collin County run $30–$48 per foot due to the sandy and mixed geology, which is somewhat easier to drill than the hard limestone counties to the west. Total project cost depends on completion depth and the full system (casing, pump, pressure tank, electrical). We provide a free itemized written estimate after reviewing neighboring driller's logs for your parcel.
Do I need a permit to drill a well in Plano?
Yes. New wells in Collin County require registration with the North Texas Groundwater Conservation District and must be drilled by a TDLR-licensed well driller. DFW Well Service manages the permitting process for all projects.
Can DFW Well Service service an existing pump on my Plano property?
Absolutely. We repair and replace submersible pumps, pressure tanks, and controls on existing wells throughout Collin County. If your well is losing pressure, cycling frequently, or delivering discolored water, call us at (940) 536-8560 for a diagnosis.
How long does it take to drill a new well near Plano?
Most residential well drilling projects in Collin County are completed in one to two days of drilling. Factor in an additional day or two for pump installation, pressure tank setup, and initial water testing. Total project time from permit to running water is typically one to two weeks.
Is the well water in Plano salty or brackish?
Generally no. Both the thinning Woodbine and the deeper Trinity that supply Plano-area wells are fresh here, and Texas Water Development Board mapping shows fresh water reaching unusually far across Collin County; the water turns slightly salty only deeper and toward the far eastern edge of the county. Test total dissolved solids (a measure of how mineral-heavy the water is) after drilling to confirm.
