What Is Water Well Drilling?
Water well drilling means boring a hole deep into the ground until you reach an aquifer — an underground layer of rock or sediment that holds clean groundwater. That water gets pumped up to your home. You own it. No bill, no interruption, no city involvement.
In St. Louis, most residential wells go 50 to 250 feet deep. The well gets lined with steel or PVC casing (a pipe that keeps the hole open and blocks surface water from getting in), sealed at ground level, and connected to a pump that pushes water into your home.
We manage the whole job — from the first site visit to the final water test. We pull your Missouri DNR permit, do the drilling, install the pump, and hand you a certified lab report on your water quality before we leave.
Well Drilling in St. Louis, MO
The St. Louis area sits at the edge of the Ozark Plateau — a region of ancient limestone and dolomite bedrock that holds some of the best groundwater in the Midwest. That geology gives us two reliable water sources. The first is the shallow alluvial aquifer — alluvial means river-deposited sand and gravel — found in the Missouri and Mississippi River valleys. Wells in those areas hit water at 50 to 150 feet. The second is the deeper Ozark limestone aquifer, which runs 100 to 250 feet down and covers a broader swath of the metro area.
Both aquifers produce clean, reliable water for homeowners. Rural properties outside the city water grid in St. Charles County, Jefferson County, and Lincoln County commonly rely on private wells as their primary water source. If your land is in one of those counties, chances are good you can have a productive well drilled.
When Do You Need a New Well?
New construction: Building a home in a rural part of St. Louis or the surrounding counties where city water lines don't reach? A drilled well is your primary water source. We work with your builder so the well is in the ground before your foundation goes down.
Existing well failure: Wells older than 30 years can lose water quality, slow to a trickle, or develop cracks in the casing. When repair costs start climbing toward the cost of a new well, replacement is the smarter long-term choice.
Property without a well: Bought rural land in the St. Louis area that doesn't have a well on it? We evaluate your land, find the best drilling spot, and put in a complete system. You get water.
Switching from city water: A new well in Missouri runs $5,000–$15,000 fully installed. City water costs a typical household $700–$1,000 per year. Most homeowners who switch pay off the well in 7 to 15 years and own their water supply outright after that — no more monthly bill, no drought restrictions.
Residential Well Drilling in St. Louis
Most of the wells we drill in the St. Louis area are for homeowners. Whether you're building on rural land, replacing an old well that's losing water, or buying property without city water access — a residential well gives your family a water supply you own and control.
In the St. Louis area, residential wells typically range from 50 to 250 feet depending on which aquifer we're targeting. We size the pump and pressure tank to match your home — accounting for bathrooms, appliances, and irrigation. A correctly sized system gives you steady pressure at every tap.
Every residential well we drill comes with a sanitary well cap, steel or PVC casing, a submersible pump, pressure tank, and water line to your home. We test the water for bacteria, nitrates, and hardness before we hand the system over to you.
Commercial Well Drilling in St. Louis
Businesses, churches, schools, and commercial properties in the St. Louis area that sit outside city water service need a water source that works every day. Commercial wells carry more demand than residential systems. They need bigger casing and higher-output pumps built for steady, all-day use.
We drill commercial wells with large-diameter casing and high-capacity pumps sized for your operations. Building a new commercial property, expanding an existing facility, or replacing an underperforming well — we design the system around your exact water volume needs.
Commercial projects often require coordination with architects, contractors, and local building departments. We handle the well permitting and water testing requirements so your project stays on schedule.
Agricultural & Irrigation Well Drilling in St. Louis
Farms and rural properties around St. Louis need water for livestock, crops, and daily operations. Agricultural wells are built for high output — they deliver the volume of water needed to run a farm without dropping pressure during peak demand.
We drill livestock and irrigation wells sized for your land and your crops. Whether you have a small hobby farm or a large-scale operation, we test the aquifer on your property first and design a well that delivers steady flow all season long.
Agricultural wells in Missouri sometimes have different permit requirements than residential wells, depending on how much water you plan to use. We handle all of that. Your well will be fully compliant with Missouri regulations before we leave the site.
Our Well Drilling Process
Site Evaluation
We come out at no charge to walk your property. We look at the soil, pull up local well records, pick the best drilling location, and check the required setback distances from your septic system and property lines. Missouri law requires this before a permit can be issued.
Permits & Approvals
We file your well construction permit with the Missouri DNR and coordinate with your local health department. You don't touch any paperwork. We handle it all before a bit hits the ground.
Drilling
Our truck-mounted rig bores through the Missouri soil and into the limestone or sand and gravel aquifer below. We install casing as we go — steel or PVC pipe that holds the hole open and keeps surface water from getting into your well.
Well Development & Testing
Once we hit the aquifer, we develop the well — that means flushing and testing to maximize flow. We drop in the pump, connect the pressure tank and water line to your home, and send a water sample to a certified lab. You get a complete well log showing depth, geology, gallons per minute, and water quality results.
Well Drilling Cost in St. Louis, MO
A new residential well in Missouri typically runs $5,000 to $15,000 fully installed. That covers drilling, casing, pump, pressure tank, and the water line to your home. The main variables are how deep we need to go and whether your ground is soft soil or hard Ozark limestone — rock takes more time and equipment.
Compare that to city water. A typical St. Louis area household spends $700 to $1,000 per year on municipal water. Most homeowners who switch to a well pay it off in 7 to 15 years and own their water supply outright after that. We visit your property and give you a detailed written estimate before any work starts — all drilling, materials, labor, permits, and water testing included. No hidden fees.

Frequently Asked Questions
How long does it take to drill a well?
Most residential wells in the St. Louis area take 1 to 3 days to drill. Deeper wells through hard limestone take longer than shallow wells in softer ground. From your first call to water running in your home — permitting, drilling, pump install, and testing — the full process usually takes 1 to 2 weeks.
How deep will my well need to be?
It depends on your location and the local geology. In the St. Louis area, most homes hit good water at 50 to 250 feet — either in the shallow river-valley aquifer or the deeper Ozark limestone. We check local well records and visit your property to estimate the depth before we start.
Do I need a permit to drill a well in MO?
Yes. Missouri requires a well construction permit through the Missouri Department of Natural Resources (DNR) before drilling can begin. We file the permit, handle the inspections, and take care of all paperwork at no extra charge.
Is well water safe to drink?
We test every new well for bacteria, nitrates, and mineral content — including hardness — before handing it over. Most wells in the St. Louis area produce safe, clean water. Missouri's limestone geology does mean the water often runs hard, but that is treatable. If testing reveals any concerns, we recommend appropriate water treatment solutions.
What warranty do you offer?
We stand behind every well we drill. Your written estimate includes specific warranty terms covering drilling, casing, and pump installation. A well we build is designed to last 25 years or more with routine maintenance.
