Well Drilling Contractor in Hartland, WI

Herr Well Drilling, Inc. has been the well drilling contractor Hartland and the surrounding communities have relied on for over six decades. Our company has been drilling water wells in Waukesha County since 1964 — a multi-generational family operation that has watched this region grow while maintaining the same commitment to well-built, properly documented water systems.


Water well drilling in the Hartland area involves a geology we know well. Glacial deposits, sand formations, and productive bedrock aquifers at varying depths depending on the specific parcel. We assess each site on its own terms.

What We Do: Well Drilling Services in Hartland

Hartland's mix of residential neighborhoods, rural fringe properties, and commercial development creates varied demand. We handle residential, agricultural, and commercial projects, and we've done all three in this part of the county regularly.


As a well drilling company with more than sixty years in this market, we know the formations here, the regulatory landscape, and the common failure points that show up when wells are installed quickly rather than correctly. That knowledge shapes how we approach every job.


Featured Services

Residential Well Drilling

Residential well drilling in Hartland serves properties across a wide spectrum — new builds that need a first well, replacement systems on homes where the original well has aged out, and service upgrades where the existing infrastructure can be partially retained. We evaluate the full picture before recommending a path.

Commercial Well Drilling

Commercial well drilling around Hartland serves businesses, light industrial facilities, and institutional properties that need a reliable water source outside of municipal supply. We engineer commercial wells for sustained output — not just initial yield — and document the production capacity before project closeout.

High-Capacity Well Installation

High-capacity well installation in this area typically serves agricultural operations, large irrigation systems, and commercial properties with significant daily water demand. The design is more rigorous, the testing more comprehensive, and the documentation more detailed. We've built these systems across Waukesha County and have the experience to do them right.

Deep Well Drilling

Some properties in the Hartland area require deep well drilling to bypass shallow formations that are either depleted or carry contamination risk. Deep well drilling requires the right equipment and the judgment to interpret what the drill tells you as you go. This is usually where people run into problems with contractors who lack both. We don't.

Why Choose Herr Well Drilling, Inc.

We are a family business. Not a franchise, not a private equity-backed regional operator — a family business that has been running in Waukesha County since 1964. The Herr family built it. The Domres family extended it. And four siblings — Nathan, Adam, DJ, and Kendel — are running it today after the unexpected loss of the previous generation in 2024.


That kind of continuity comes with something you can't replicate: generational knowledge of this specific ground. The current owners grew up in this business. They know the county's geology the way only repeated, hands-on exposure teaches.


When Hartland property owners search for well drilling near them, they need a well drilling contractor with a record in this county—not a company that showed up last year. Sixty years of history is a record.

Frequently Asked Questions (FAQs)

  • How long has Herr Well Drilling been operating in the Hartland area?

    Since 1964. We've been drilling wells in Waukesha County — including the Hartland area — for over sixty years. The company is still owned by the same family that founded it.

  • What should I do if my well water suddenly smells or tastes different?

    Don't ignore it. Changes in water quality can indicate bacterial contamination, changes in the aquifer, or issues with the well casing. Stop using the water for drinking and contact us to arrange an inspection and water quality test. We can usually get to an emergency call quickly.


  • How is a drilled well different from a driven or bored well?

    Drilled wells go significantly deeper and are sealed with steel casing that prevents surface water from entering the system. Driven and bored wells are shallower, more susceptible to contamination, and generally no longer appropriate for primary domestic water supply. All new wells we install are drilled.

  • Can the existing pump from an old well be reused in a new one?

    Occasionally, if the pump is relatively new and in good condition, and the new well is similar in depth and yield. More often, a new well installation warrants a new pump — the pump should be matched to the well's specific characteristics for optimal performance. We evaluate this on a case-by-case basis.

  • What causes low water pressure and is it always a well problem?

    Not always. Pressure problems can originate at the pump, the pressure tank, the pressure switch, or in the plumbing itself. A service call usually identifies the source quickly. We don't recommend replacing the well without first diagnosing whether the issue is actually well-related.
