Collin County Is Growing Fast — And So Is the Demand for Private Wells

Collin County has been one of the fastest-growing counties in the United States for over a decade. McKinney, Celina, and Anna are absorbing thousands of new residents each year. But city water infrastructure doesn’t grow as fast as subdivisions, and rural properties — especially in the eastern and northern parts of the county — are still relying on private water wells.

If you’re buying land in Princeton, Farmersville, or the rural corridors outside Prosper, there’s a good chance you’re looking at a well. TurnKey Wells drills, pumps, and services domestic and agricultural wells throughout the county.

Geology and Drilling Depths in Collin County

Collin County sits over the Woodbine and Paluxy aquifer formations. These are the same formations that serve much of North Texas, but here they run deep — our records show a median pump depth of 680 feet, with many wells reaching 800–900 feet or beyond. That puts Collin County wells at the deeper and more expensive end of the North Texas spectrum.

The Woodbine is a sandstone formation that holds good-quality water but requires drilling through harder cap rock to reach it. That’s why working with an experienced, licensed driller matters here — a driller who underestimates the geology can end up dry or short of usable water.

What Does a Water Well Cost in Collin County?

Because of depth, expect to budget more than the DFW county average. Drilling rates run $65–$120 per foot in North Texas. At 680 feet, that’s $44,000–$82,000 in drilling costs alone before pump and system installation. Total residential well projects typically land in the $25,000–$40,000+ range depending on final depth, geology encountered, and the pump system selected.

• Drilling: $65–$120/ft
• Pump & pressure system: $3,000–$8,000
• Permits: $500–$1,500
• Full residential well: $15,000–$40,000+

We give honest quotes before we start drilling. No surprises.
