Selling a water well and pump company

More than 43 million people, about 15 percent of the US population, rely on a private well for drinking water, and EPA estimates that more than 23 million households do¹². Those wells are not covered by the federal Safe Drinking Water Act or, in most states, by state law, so the homeowner is responsible for keeping the system working and the water safe¹². When a pump fails, the household has no water until someone like you shows up.

A new well depends on someone building a house or a farm adding irrigation, so drilling rises and falls with construction and crop prices. Pump replacements, pressure tanks, controls, well rehabilitation and treatment, which most homeowners cannot put off, depend on the wells already in the ground, and that installed base gets older every year. Buyers usually see the service side as the steadier half of the business.

Fragmentation is the other draw. When O2 Investment Partners invested in Steffl Drilling & Pump in April 2026, it described Steffl as a regional leader in an essential, non-discretionary category within a highly fragmented industry⁹. Steffl, a Willmar, Minnesota company founded in 1978 whose CEO is the son of its founders, serves residential, agricultural, commercial and municipal customers across the full life of a well, and also takes on PFAS-related remediation and geothermal work⁹.

Other recent deals follow the same pattern. In February 2026, XPV Water Partners invested in Weisinger Incorporated, a Texas groundwater and water well services company in its 50th year, as the start of a water well services platform¹⁰. In August 2025, Coltala Holdings launched Coltala Water Holdings by acquiring Alsay, a Houston well drilling and service company founded in 1960¹¹. In January 2026, Bennett West, a Pike Street Capital portfolio company that serves Central Valley growers, added Madera Pumps, a pump and well services business working in the region since 1977¹².

Being a platform or an add-on changes what a buyer needs from you. A platform needs a management team, systems and room to absorb more acquisitions. Weisinger, for example, brought in a new CEO and CFO from outside while its longtime family leaders stayed on¹⁰. An add-on is folded into an existing company, so the buyer cares most about your customers, licensed people, equipment and how your area fits theirs. You are likely to hear from:

• Private equity firms building water well platforms, which want a strong regional operator first and smaller add-ons nearby.
• Water-focused investors and companies that own pump, treatment or groundwater businesses and want more drilling or service capacity.
• Home services platforms with plumbing, water treatment or HVAC companies in rural and exurban markets.
• Family offices, independent sponsors and holding companies, which often do one deal at a time and hold longer.

A buyer's first question is usually how much of your revenue comes back without a new house being built. A company with a large, growing service base will usually draw more interest than one of the same size that depends on drilling new wells.

Within service, buyers look closely at emergency calls. A no-water call on a Saturday is urgent work that customers rarely shop on price, and it often leads to a new pump, a pressure tank or a treatment system. Show how many of these calls you take, how fast you respond and how often they turn into larger jobs.

Planned work matters too. EPA recommends that private well owners test their water every year for total coliform bacteria, nitrates, total dissolved solids and pH³. If you run an annual testing program, sell maintenance plans or service the softeners, filters and UV units you install, you have something close to recurring revenue. Buyers will want customer counts, renewal rates and revenue for each program.

Equipment is a bigger part of value here than in most service trades. Rigs, pump hoists, support trucks, water trucks and trailers are worth a lot and expensive to replace. Coltala's release on the Alsay deal, for example, pointed out that Alsay runs one of the largest drilling fleets in Texas¹¹. A buyer will want the age, hours, condition and maintenance history of each unit, and what you have been spending to keep it running.

Buyers also look at where your customers are and how they find you. Tight density keeps drive time down on long rural routes, and steady referrals from builders, realtors, home inspectors and plumbers show that your reputation brings in work. The figures buyers ask for most often include:

• Revenue and gross margin by line: drilling, service, treatment, testing and commercial work
• Service calls per month, the share that are emergencies and the average ticket
• Testing and maintenance customers, with renewal rates
• A rig and truck list with year, hours, condition and replacement plans
• Customer and job counts by county or service area
• Where new customers come from, including builder and realtor referrals

Licensing is set state by state, and EPA advises homeowners to confirm that their drillers and pump installers are licensed and certified where the state requires it⁴. How your licenses are held matters a great deal in a sale.

In Texas, a license is required both to drill a water well and to install a pump in one⁵. Individuals apply for driller and pump installer licenses based on at least two years of relevant experience under a licensed driller or installer, then pass an exam, and the license is valid for two years⁶. A licensee may directly supervise no more than one unlicensed assistant, although they may oversee as many registered apprentices as they can properly supervise⁷. In practice, the number of licensed people on your payroll sets how many crews you can run.

Minnesota takes a different approach. The Minnesota Department of Health licenses the company and certifies a qualified individual who has passed an exam as the company's certified representative⁸. The company license also requires registering drilling machines and hoists and posting a corporate surety bond, and an applicant for the full well contractor license needs four years of experience⁸. A buyer in Minnesota will want to know who your certified representative is and who could step into that role if that person leaves.

Either way, if you are the only person holding the key license, the business cannot legally do some of its work without you. Buyers handle this by asking you to stay on, by tying part of the price to a smooth handoff, or by waiting until someone else on your team is licensed. Some states use the National Ground Water Association's voluntary certification exams as their licensing test, so national certifications on your team can help⁴.

Compliance history is part of the same review. Texas, for example, collects well reports through an online reporting system and lets anyone search the disciplinary actions it has taken against licensees⁵. Expect a buyer to check your record wherever you work, so review it first.

Few issues end a deal on their own, but each can lower the price or move more of it into earnouts and holdbacks. The most common are:

None of these is unusual in a family-run well company. What matters is finding them early and fixing what you can before a buyer finds them.

• Heavy dependence on new construction. If most of your revenue comes from drilling for a few builders, a slow housing year shows up directly in your earnings.
• One customer or builder that makes up a large share of revenue, with no contract behind the relationship.
• Licenses held only by the owner, or by one long-time employee who has no plans to stay.
• An aging fleet. Old rigs with deferred maintenance mean the buyer expects to spend money soon, and will price that in.
• Permit and reporting gaps, such as missing well logs, late reports, unresolved complaints or disciplinary actions.
• Books that mix drilling, service and treatment together, so a buyer cannot see which part of the business earns the margin.
• Customer and well records kept in the owner's head or in paper files, which makes the service base hard to measure.

Many deals of this size are asset purchases, where the buyer acquires the equipment, customer relationships, name and other assets rather than the company itself. In that kind of sale, both you and the buyer generally file IRS Form 8594, which allocates the price across classes of assets¹³. Vehicles, equipment, buildings and land generally fall in one class, and goodwill in another¹³. With rigs and trucks so central to a well company, that allocation deserves attention.

It also affects your taxes. Gain on equipment you have depreciated is generally treated as ordinary income up to the amount of depreciation taken¹⁴. If you have written off your rigs quickly, a large allocation to equipment can change what you keep after tax. Bring your tax advisor in before you agree to terms, not after.

Real estate is often handled separately. If you own the yard and shop where your rigs, pipe and pumps live, you can usually sell it with the business or keep it and lease it to the buyer. A lease gives you rental income, but expect the buyer to ask for market rent and a long term.

Most of the price is usually paid in cash at closing, but you will also see:

Ask early whether the buyer plans to keep your name, trucks and phone number. Well customers tend to call the company they have used for years, so a local brand is often worth keeping, but get the plan in writing.

• Rollover equity, where you keep a minority stake in the buyer's company and share in a later sale. In the Alsay deal, the company's earlier investor kept an investment and a board seat after the sale¹¹.
• Earnouts tied to future revenue or earnings, common when drilling volume swings or a large contract is up for renewal.
• Seller notes, where part of the price is paid over time.
• Holdbacks or escrows that cover equipment condition, customer issues or compliance problems found after closing.
• A transition period for you, often longer if you hold a key license or run most of the customer relationships.

Preparation pays off whether you sell in two years or ten. Start with these steps:

It also helps to decide what you want from a sale: a full exit, a partial sale with rollover, a role for family members or a set period working with the new owner. Clear priorities let you compare buyers on more than price.

• Separate revenue and job costs into drilling, service, treatment and testing, and commercial or agricultural work, for at least two full years.
• Build a fleet register for every rig, hoist, truck and trailer, with year, hours, condition, maintenance and inspection records, and liens.
• Map every license, certification, registration and bond, including whose name each is in and when it renews.
• Get a second person licensed, or train a successor, so the business does not rely on you alone.
• Pull together your permit history, well reports and any complaints or enforcement actions, and close out anything left open.
• Move customer, well and service history into one system, so a buyer can see how many households you serve.
• Put testing and maintenance programs on written terms, and track renewals.
• Decide what to do with your real estate, and get it appraised if you plan to lease it.
