Well Drilling Contractor in Oconomowoc, WI

Herr Well Drilling, Inc. has been the well drilling contractor Oconomowoc property owners call when the job needs to be done right. Since 1964, our family-owned company has been drilling wells across Waukesha County — and the Oconomowoc area has been a consistent part of our territory.

We bring that knowledge to every project. Four generations of it.

What We Do: Well Drilling Services in Oconomowoc

The Oconomowoc area is a mix — lake-area properties, rural acreage, residential subdivisions on well water, farms, and commercial operations. Each setting presents different demands and different underground conditions. Our well drilling services are structured to handle all of it. Many homeowners in the area also ask about our well drilling company serving Metro Milwaukee.

We manage the full scope: site evaluation, DNR permitting, drilling, casing, pump installation , and water testing . Our well drilling company doesn't hand off phases to other contractors. The crew that evaluates your site is connected to the crew that drills it.

This matters because continuity in the field reduces errors. The person running the rig knows what was found during the site review. Decisions get made with full information. Explore our farm well drilling for more details.

Featured Services

Residential Well Drilling

Residential well drilling in Oconomowoc covers new construction wells on undeveloped lots, replacement wells for aging systems, and emergency drilling when an existing well fails. We work with homeowners to size the system correctly for household demand, pull the necessary permits, and complete installation through full pump startup and water quality testing.

The lake communities in this area sometimes present unique setbacks and contamination concerns. We know how to navigate those. We also provide directional drilling services.

Commercial Well Drilling

Commercial well drilling around Oconomowoc serves a range of operations — resorts, agricultural facilities, manufacturing properties, and commercial developments. These projects require higher yield targets and more robust engineering than residential systems. We design commercial wells around the operational demands of the property, not just minimum code requirements.

High-Capacity Well Installation

High-capacity well installation is a separate discipline. When a property needs to move serious volume—irrigation systems, food processing, livestock operations—the well design changes significantly. Yield testing during development confirms the formation can sustain the load before the system is finalized. Learn more about our well development services.

Deep Well Drilling

Depth requirements vary across the Oconomowoc area depending on where productive aquifers sit beneath a given parcel. Deep well drilling requires equipment capable of reaching those formations without compromising casing integrity on the way down. We've been doing this in this county long enough to know when a formation is productive and when to keep drilling.

Why Choose Herr Well Drilling, Inc.

Water well drilling contractors come and go. Companies are acquired, rebranded, and staffed by crews with no connection to the region they're serving. Herr Well Drilling, Inc. is the opposite of that.

John Herr Sr. was a master plumber who brought a drilling rig to the family operation decades ago. His son John Jr. built the drilling business into a full-time operation. Theresa Domres — John Jr.'s daughter — eventually became president of the company. And now, after an unexpected loss of both Theresa and her husband Greg in 2024, the company is owned and operated by their children: Nathan, Adam, DJ, and Kendel. Our crews regularly handle residential well drilling.

This is a family that has not walked away. Four generations in.

Frequently Asked Questions

What makes the Oconomowoc area geology different for well drilling?

This part of Waukesha County sits over a mix of glacial drift and bedrock formations. Depending on your parcel, you may encounter sand and gravel aquifers at shallower depths or need to go deeper into bedrock for a clean, reliable source. We evaluate each site individually — there's no universal answer for this area.

How close to a lake or pond can a well be drilled?

Wisconsin DNR setback requirements exist for a reason — surface water can introduce contamination into shallow aquifers. Minimum setbacks from surface water, septic systems, and other potential contamination sources are part of every permit review. We factor these in during the site assessment phase.

Do you handle well abandonment for old systems?

Yes. Wisconsin requires that unused wells be properly abandoned to prevent surface water from entering the aquifer. We handle full well abandonment in compliance with DNR requirements.

How do I know if my current well is producing enough water for my property?

If you're noticing pressure drops during high-demand periods, air in the lines, or discolored water, those are indicators worth investigating. We conduct yield assessments on existing wells to determine whether the current system can meet your demand or whether replacement is the more practical path.

Are your prices fixed or will they change mid-project?

We provide detailed estimates before work begins. Changes in scope — typically caused by unexpected geological conditions — are communicated before we proceed. No surprises on the invoice.
