What depth to expect in Collin County

We will be straight with you about the numbers. Triangle J has one Collin County well on the Texas public record, completed to 420 feet. One filed well is not a depth forecast for your property, so we lean on the bigger picture: next door in Denton County our 37 public-record wells average 499 feet, and Trinity Aquifer wells across this part of North Texas commonly fall between 200 and 800 feet. The Trinity is the workhorse aquifer for homes and agricultural properties here, with the Woodbine shallower in certain zones. Here is how the two compare.

Before we quote a Collin County well, we pull the state well records around your specific property: historic water levels, formations, and the depths your neighbors' wells actually reached. That records check, not a county average, is what your estimate is built on.

Permits and practical rules

New wells in North Texas go through a groundwater conservation district filing plus the state TDLR paperwork. We confirm which district covers your Collin County property when we pull the records, and we coordinate and handle most of the permitting, which typically takes 2 to 4 weeks in most North Texas counties. Engineered site plans, where required, stay with the property owner. We also typically drill on properties of 2 or more acres, per county rules, so smaller lots should confirm with the county first.

Curious what the whole system costs? Complete residential and light-ag systems in North Texas typically run $11,000 to $60,000 or more. The cost guide explains what moves the number. You can also browse our neighboring county pages for Denton and Cooke counties, or the full list of towns we serve.
