Wells around Krum draw from the Trinity aquifer, the primary residential water source across western Denton County. Most domestic wells here complete in the upper Paluxy sand or the deeper Twin Mountains sand. Between those two sits the Glen Rose Formation — mostly solid limestone that holds little water, so a well is cased through it to reach the sand below rather than producing from it; toward the northwest of the county the Glen Rose begins to thin. The Woodbine, a shallower layer, is a minor secondary target on some Denton County parcels. Depth varies meaningfully from one parcel to the next, so there’s no single typical figure for the county.

Drilling rates in Denton County typically run $38–$50 per foot. Mixed formations and occasional hard limestone can affect total project cost.

Denton County Permit Requirements

New wells in Denton County are regulated by the North Texas Groundwater Conservation District. A pre-drilling permit is required for all new well construction, and even exempt domestic and livestock wells must register with the district.

Frequently Asked Questions

Why do many Krum properties use private wells?
Krum sits in the rural, agricultural northwest of Denton County, where farms and acreage homesteads spread out beyond the town's small core. Many of those tracts are outside a municipal water line, so a private water well is the standard source for the home, livestock, and irrigation.
How deep are wells in the Krum area of Denton County?
Depth varies meaningfully from one Krum parcel to the next, so there's no single typical figure — we review the driller's logs from neighboring wells before quoting a depth for your property. Most domestic wells here complete in the Trinity aquifer's Paluxy and Twin Mountains sands, and how deep that sand sits changes across short distances. Longer term, the district projects the water level in the deeper Twin Mountains sand under Denton County to drop several hundred feet, which is worth designing the well around.
Which GCD covers wells in Krum?
Krum is in Denton County, which falls under the North Texas Groundwater Conservation District. A pre-drilling permit is required, and even exempt domestic and livestock wells must register with the district. DFW Well Service submits permit applications on your behalf as part of the drilling process.
What does well drilling cost in Krum?
Denton County drilling rates typically run $38–$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 inspect a well on a property I'm buying near Krum?
Yes. We perform well inspections and flow tests for real estate transactions throughout Denton County. A pre-purchase inspection includes a visual assessment of the wellhead, a flow rate test, and a report suitable for your due diligence file.
Do you handle pump replacements in Krum?
Absolutely. We replace and repair submersible pumps, pressure tanks, and associated electrical systems on existing wells throughout Denton County. If your pump has failed or your water pressure has dropped, call us for a same-day or next-day service visit.
Is the well water in Krum salty or brackish?
Generally fresh. Krum draws from the Trinity — and from the Woodbine in eastern Denton County — which the Texas Water Development Board maps as fresh in this area. The water turns slightly salty only farther downdip, meaning farther along where the layer tilts deeper. After drilling, test for total dissolved solids (a measure of how mineral-heavy the water is), sulfate, and iron.
