What to ask every contractor

Frequently asked questions about water well drilling in Williamson County

How much does a water well cost in Williamson County, Texas?
Most residential water wells in Williamson County run $10,000–$25,000 for a complete drilled and cased well with pump, pressure tank, and electrical hookup. Hill Country wells trend higher because of limestone drilling ($30/foot vs $22/foot in East Texas), while wells in eastern parts of the county are cheaper due to softer soils. Depths average 200–500 feet in Central Texas. Ask each driller for a per-foot rate and a not-to-exceed cap.
Do I need a permit to drill a well on my property in Texas?
Texas is a private-property groundwater state, so most rural landowners can drill without a permit — but you must use a TDLR-licensed driller and file a State of Texas Well Report within 60 days of completion. Some Groundwater Conservation Districts (Central Texas has several) require registration before drilling. Your driller will handle the paperwork. Every contractor on this page is TDLR-licensed and filed on the state opt-in roster.
How deep will my well need to be?
In Williamson County, expect 200–500 feet for a household well. Water table depth varies by property — your driller can review nearby wells via the TDLR well database to give you a solid estimate before quoting. Deeper wells cost more per foot but are less likely to go dry during drought. Ask for at least 3 nearby completed-well references before choosing a depth.
How long does it take to drill a residential well?
Typical well drilling projects take 3–7 working days from rig-up to running water. Add 1–2 weeks upstream for permitting (if applicable), driller scheduling, and pump/equipment procurement. Fastest turnarounds happen in fall and winter when demand is lowest. Summer bookings often push out 4–8 weeks in Central Texas.
How do I know if a well driller is legit?
In Texas, well drillers must hold an active TDLR license and post a $10,000 bond. Every contractor on this page is verified against the Texas Department of Licensing and Regulation opt-in roster. Beyond that, ask for: proof of current insurance, 3 references from Williamson County jobs in the last 12 months, a written estimate with per-foot pricing, and a copy of the well log they will file with the state.
