Professional Well Drilling Services in Dousman, WI & Metro Milwaukee
Water access isn't something most property owners think about until something goes wrong — or until they're building somewhere that doesn't have it. Herr Well Drilling, Inc. has been handling both situations since 1964, serving homeowners, farmers, and businesses throughout Dousman, WI and Metro Milwaukee for over six decades. We're a fifth-generation, family-owned well drilling company, and this region is the only market we've ever worked in. That matters more than it might sound.
Southeast Wisconsin has its own geological personality — the limestone formations of the Kettle Moraine, the varied sand aquifers across Waukesha County, the depth variations that shift significantly from one township to the next. Knowing that terrain comes from drilling in it for generations, not from reading about it.
What We Do
The core work is straightforward: we drill water wells for residential properties, farms, commercial facilities, and everything in between. What's less straightforward is doing it well.
Every project starts with a site evaluation and a review of local well records through the DNR database. This is usually where inexperienced contractors run into problems — skipping that step and treating every job like every other job. We don't. The aquifer data for your property in Dousman will look different than a property five miles east, and the drilling plan should reflect that.
Our well drilling services include residential well drilling for new construction and rural property development, commercial well drilling for businesses and facilities with significant water demands, high-capacity well installation for farms and operations that need sustained, heavy output, and deep well drilling where shallow formations won't produce clean or adequate water. Every well is finished with proper casing, grouting, and well cap installation — all in full compliance with Wisconsin DNR requirements.
Why It Matters Who You Call
There are other water well drilling contractors in Southeast Wisconsin. We're not the only option, and we won't pretend to be. What we will say is this: the Herr family has been doing this work in this area since 1964, and that history isn't just a selling point. It's the reason we know what to expect at depth on a Waukesha County property, why we recognize conditions that will require a change in approach before they become expensive surprises, and why our estimates are honest rather than optimistic.
We're licensed, properly insured, and current on Wisconsin well construction standards. We use modern drilling equipment because accuracy matters more than speed — an older rig that can't hold precise depth control in a difficult formation creates problems that show up later, not on the day of the job. Free estimates are available within 48 hours, and we don't follow up with pressure. You have time to make a good decision.
Key Benefits of a Private Water Well
For properties in rural and semi-rural parts of the Metro Milwaukee region, a private well removes a genuine constraint. Municipal water doesn't reach everywhere, and where it does reach, it comes with rate structures and system vulnerabilities that are entirely outside a property owner's control.
A properly constructed well gives you:
Water independence
Your supply isn't tied to infrastructure decisions made by someone else
Long-term cost predictability
Ongoing costs after installation are electricity and periodic maintenance, not monthly utility bills subject to increases
Quality control
Your water can be tested and treated to your specific standards
Property value
A functioning, well-documented well is a real asset, particularly in rural Waukesha County real estate
Flexibility
Wells can be designed around your actual water demand, whether that's a single household or a working farm
Along the I-94 corridor and out through the Kettle Moraine, water availability shapes what a property can do. Getting the well right from the start is the difference between a system that works for 40 years and one that creates problems inside of ten.
Featured Services
Residential Well Drilling
Most of our residential projects fall into two categories: new construction on properties without public water access, and replacement wells on older rural properties where the existing well has declined in performance or failed entirely. We evaluate water demand and local geology before drilling, and we complete every residential well with pump sizing guidance and pressure tank recommendations — because a well that's drilled correctly but connected to a mismatched pump system won't perform the way it should.
Commercial Well Drilling
Commercial water demands don't leave much room for underperformance. We work with facility managers, developers, and contractors on commercial well drilling projects where yield requirements, flow rates, and permitting compliance are all non-negotiable. Documentation is thorough on every commercial job — for permits, for records, and for the property owner's own protection.
High-Capacity Well Installation
This is where undersizing a well creates the most damage. A high-capacity well serving an irrigation system or large agricultural operation needs to be matched carefully to the aquifer's actual sustainable yield. Get that wrong and the system will struggle through its first dry season. We do the aquifer evaluation work upfront and size the well and pump to match real-world demand, not best-case assumptions.
Water Well Installation for Irrigation
Demand for dedicated irrigation wells has grown steadily across the Oconomowoc and Waukesha areas as property owners look to reduce municipal water dependency for crops, lawns, and landscaping. We drill irrigation wells to the output specifications of the irrigation system and can advise on pump selection and pressure setup to make sure the entire system works as a unit.

Frequently Asked Questions
How deep does a well need to be drilled in Southeast Wisconsin?
It depends on the property. Productive aquifers in much of Waukesha County sit between 100 and 400 feet, but that range shifts based on local geology. We pull DNR well records for the area before drilling so we're working with real data, not averages.
How long does a well drilling project take?
Most residential jobs wrap up in one to two days. Commercial and high-capacity wells run longer depending on depth and conditions. We give you a timeline during the estimate — and we mean it.
What's the difference between a drilled well and a dug well?
A drilled well uses steel or PVC casing and goes deep into bedrock or sand aquifers. A dug well is shallow, more vulnerable to contamination, and no longer the standard. All of our wells are drilled wells meeting current Wisconsin DNR construction requirements.
Do I need a permit to drill a well in Wisconsin?
Yes — and we handle it. Permitting is part of our standard process on every job.
How do I know if my property can support a well?
Most properties in our service area can. We evaluate DNR records and site conditions before committing to a drilling plan, so we have a realistic picture of what to expect at your location specifically.
What happens after the well is drilled?
We install casing, grout the annular space, and set the well cap. Then we run initial pump testing to confirm yield and water quality before making any pump or pressure system recommendations.
How long does a drilled well last?
A well that's constructed properly can last 40 years or more. The pump and pressure tank will need attention sooner — typically somewhere between 10 and 25 years depending on usage and water quality.
Do you offer warranties on your work?
We stand behind our construction. If something is related to our workmanship, we address it. The specifics are covered during the estimate and contract phase of each project.
