TL;DR

Colorado's Board of Examiners of Water Well Construction and Pump Installation Contractors licenses people who construct wells or install pumps for others. You also need a well permit from the Division of Water Resources before you drill. Private work on your own property has a narrow exemption. Fees, exam dates, and processing times change. Confirm them on the current DWR board pages before you apply.

What is the well driller board in Colorado?

The well driller board in Colorado is the Board of Examiners of Water Well Construction and Pump Installation Contractors. It works through the Division of Water Resources (DWR) inside the Department of Natural Resources. It licenses contractors, sets construction standards with the State Engineer, and disciplines people who break those rules.[1]

It is a licensing board. C.R.S. Title 37, Article 91 is the Colorado statute that licenses water well construction and pump installation contractors.[4]

This is not a trade club. It does not exist to send you leads.

If you want to construct water wells or install pumping equipment for other people, this board issues the ticket. Homeowners still live with its rules, because the person they hire has to follow 2 CCR 402-2, the statewide well construction regulations.[5]

Treat the published statute and the CCR as the job spec. Not a Facebook thread. Not what worked on a Georgia job last summer.

The board's lane is construction competence and groundwater protection. Water rights and the well permit sit on a different DWR desk. Mix those two and you will waste a season.

Read the current board pages before you spend on letterhead or a used rig.[1] The site changes forms. Your memory of a 2018 packet is not a filing system.

Do you need a license for well driller in Colorado?

Yes, if you construct water wells or install pumping equipment for others. C.R.S. Title 37, Article 91 makes unlicensed contracting unlawful unless you fit a written exemption.[4] A private person working only on their own property may qualify for a narrow private-driller path. That path is not a contractor license, and it does not let you hire out.

Two papers get confused here. The contractor license is about who may physically construct the well or set the pump. The well permit is about whether that hole may exist and what it may pump. You usually need both before a legal, useful well exists.[2][3]

"EPA regulates public water systems; it does not have the authority to regulate private drinking water wells." That sentence is from the U.S. Environmental Protection Agency.[7] Colorado fills that gap with the Board of Examiners, DWR permits, and 2 CCR 402-2. Do not expect EPA to license your rig.

Authorized individuals can do specified work under a licensed contractor. They are not a loophole for running your own company. If you want to bid jobs, get the contractor license.

I'd rather see you spend a couple of years on someone else's rig, then sit the exam, than buy a used rotary and hope the board never notices. They notice. Neighbors notice. County people notice.

A well driller Colorado owners hire should be able to show a current board credential and a permit number before the bit turns. If they shrug at either one, hire someone else.

Colorado is not Arizona. It is not California. It is not Idaho. Read Article 91, not a national myth about "most places don't care."

What license types does Colorado actually issue?

Colorado splits the work. You can hold a water well construction contractor license, a pump installation contractor license, or both if you qualify and pass what the board requires for each. Confirm the current application categories on DWR's well construction pages before you print anything.[1]

CredentialWho it is forWhat it covers
Well construction contractorPerson or firm licensed by the boardConstructing water wells for others
Pump installation contractorPerson or firm licensed by the boardInstalling pumping equipment for others
Private driller or private pump installerLandowner on their own propertyLimited own-property work only
Authorized individualCrew working under a contractorSpecified tasks under that license

Private drillers exist so a landowner can do limited work on their own land. They are not a cheap contractor license. If you drill for a neighbor as a favor and take money, you have left the exemption.

Authorized individuals are how a licensed shop staffs a second rig without handing every helper a contractor ticket. Useful if you are building a crew. Useless if you are trying to skip the exam.

Monitoring and observation holes have their own construction language inside 2 CCR 402-2. Do not assume a water-well ticket automatically covers every boring you want to bid. Read the definitions in the rule.[5]

If I were starting out, I would decide whether I am a hole person, a pump person, or both. Dual tickets make sense if you will sell complete residential systems. They mean extra exam prep and extra bond and insurance conversations. They are not automatically better.

Colorado well work: three numbers that actually matter License statute, common exempt-well cap, and the two papers you need before a legal hole 91 C.R.S. article that licenses contractors 15 Common exempt domestic well cap (gpm) 2 Separate papers before most legal holes (license + Source: Colorado Revised Statutes Title 37, 2023

How do you apply and what does the exam cover?

You apply to the Board of Examiners through the Division of Water Resources. Expect an application, proof of experience, fees the board sets, a surety bond in the amount the statute and board currently require, and a written exam. Confirm every one of those items on the current DWR licensing materials. I am not going to invent a fee or a sitting date. Those move.[1][4]

The exam is about Colorado law and the construction rules, not about how proud you are of your mud mix. Article 91, 2 CCR 402-2, grout, casing, disinfection, reporting, and the line between well construction and pump installation. If you cannot explain why a grout interval exists, you are not ready.

Waste of money: guarantee-pass packets from random websites. Study the rule PDF and the statute. Sit with a licensed contractor and walk real jobs. That is the curriculum.

Processing is not a vending machine. The board meets on its own calendar. No article should promise you a license by a certain Friday. If someone does, they are selling.

Out-of-state drillers do not get a handshake deal I would bet a rig on. Bring your experience letters and plan to take Colorado's exam. Same advice I would give someone coming from Illinois or Florida.

I would not order letterhead, magnetic truck signs, or a second mud pump until the board has actually issued the license. Paper first. Iron second.

How much does well driller cost in Colorado?

Two different bills hide in that question. Licensing yourself is one. Drilling a well for a customer is the other.

Contractor license costs are set by the board and the statute. They include application and exam charges, a surety bond, and whatever insurance a customer or general contractor will demand. Renewal fees come later. Confirm the current dollar amounts with DWR. Do not use a blog number from 2019.[1][4]

The well itself is a depth and geology problem. Front Range Denver Basin holes can run hundreds of feet. Some go much deeper. Mountain fractured-rock wells are a different bet. Eastern plains wells sit in different aquifers, including designated basins that change the permit fight more than the bit.[9][11]

Nobody has a clean statewide average I would quote as official. CSU Extension's private-well fact sheet walks homeowners through planning and protection, not a single bid price.[6] An 80-foot sand well and an 800-foot bedrock well are not the same product.

A complete residential system (hole, casing, grout, pump, pitless or equivalent, pressure tank, disinfection, tests) often lands in the several-thousand to tens-of-thousands band once depth, mobilization, and pump size show up. Get two or three written bids from currently licensed contractors. Compare footage rates only after you compare what is included.

Waste of money: the cheapest footage rate that quietly skips grout intervals or report filing. You will pay for that hole again.

Permit fees are separate and published by DWR. Confirm them on the well permitting materials before you write the check.[2][3] I will not invent a current permit fee here.

If you are pricing your first year as a contractor, budget for bond, insurance, report time, and dry holes. The license fee is not the expensive part.

How long does well driller take in Colorado?

Licensing takes as long as your experience, the board's exam calendar, and your paperwork. There is no honest public stopwatch. Confirm current sitting dates and any stated review windows with the board. I will not invent a processing time.[1]

Building the experience to sit as a contractor is the slow part. Plan in years, not weekends, unless you already have documented time on a licensed crew.

Once you are licensed, a typical residential hole can be permitted, drilled, developed, and equipped on a timeline that is mostly about DWR permit review, weather, access, and whether the first hole makes water. On-site drilling might be a day or several days. Deep Denver Basin work runs longer. Pump install and electrical is another visit.

The permit can be the long pole. Exempt household wells in some areas move faster than non-exempt wells that need augmentation plans or Colorado Ground Water Commission action in a designated basin.[9][10] Nobody should promise you a permit date in a sales pitch.

If the question is how long until I am a working Colorado well driller, count experience first, then exam and bond, then the first permitted job. If the question is how long to drill my house well, ask licensed bidders for a schedule that starts after the permit is in hand.

I would not tell a homeowner "we can be making water next week" until I have read the permit file. That promise is how you buy a complaint.

Do you still need a well permit if you are licensed?

Yes. A contractor license does not replace a well permit. DWR well permitting is a separate process under Colorado water law, including C.R.S. Title 37 provisions on groundwater and exempt wells.[2][3][4]

Most new wells, replacement wells, and changes of use need a permit from the State Engineer before construction. Designated groundwater basins on the eastern plains add the Colorado Ground Water Commission.[9][10]

Exempt wells (the household well many people mean) often live under C.R.S. § 37-92-602. That section frames exempt-well limits, including the common 15 gallon per minute cap.[4][11] That 15 gpm figure is a legal cap, not a pump-curve suggestion.

PaperWho issues itWhen you need it
Contractor or pump licenseBoard of Examiners through DWRBefore you construct wells or set pumps for others
Well permitState Engineer / DWR (Commission in designated basins)Before you construct most wells
Construction or pump reportYou file with DWRAfter the work, on the rule's clock

Forms change names and editions. You will still hear GWS numbers in the field. Use the current PDF from DWR, not a copy in a truck glove box from 2014.[3]

I'd pull the permit, read every condition, then drill. I would not start the hole and catch up on paper. That is how people buy enforcement actions.

What does 2 CCR 402-2 require on the hole?

2 CCR 402-2 is the Code of Colorado Regulations series titled "Rules and Regulations for Water Well Construction, Pump Installation, Cistern Installation, and Monitoring and Observation Hole/Well Construction." That title is the board and State Engineer's rulebook for how the hole is built.[5]

It is the statewide rulebook for how a Colorado water well is constructed and how a pump is installed.[5]

The rules cover location, casing, annular grout, disinfection, cisterns, monitoring holes, and what you must report. They are more specific than a handshake "we always do it this way." If your grout interval does not match the rule for that well type, you are wrong, even if the well makes water.

CSU Extension's private-well fact sheet is the homeowner translation of why location and construction quality matter.[6] It is not a substitute for 2 CCR 402-2.

Setbacks from septic tanks, soil absorption systems, and other contamination sources are in the rule. Confirm the current feet in the current rule text. I will not recite a table from memory and watch it go stale.

This is where a grout log stops being bureaucracy and starts being how you prove the annular seal. WellDrillerPath sells a $179 one-time Well Board + Grout-Log Kit if you want a simple field folder. The official DWR forms still win if you actually fill them out.

I would print the current CCR PDF and mark the well types I actually bid. You do not need to memorize monitoring-hole language on day one if you will only drill household wells. You do need the grout and casing sections cold.

What reports do you file after you drill or set a pump?

You file construction and pump installation reports with DWR on the current official forms, in the time window the rules require. The well construction report is how the State Engineer learns what was actually built, not what the permit hoped for.[1][2][5]

Late or missing reports are a classic way to get the board's attention. They are also how a later owner gets a useless well file when they try to replace or refinance.

Pump installation reports are not optional just because the hole guy already filed something. If you set the pump, file your paper.

Keep copies. Keep the grout intervals, casing schedule, static level, test data, and legal location the way the form asks. The permit file will outlive your memory.

I'd rather over-document the first fifty wells than argue with a complaint file later. A photo of the grout tickets is cheap. A reconstructed log from memory is not.

If a homeowner asks why the paperwork takes a day after the rig leaves, tell them the truth. The report is part of the well. Colorado treats it that way.

What if you work without a Colorado well license?

Unlicensed well construction or pump installation for others is unlawful under Article 91. The board can go after the person who did the work. DWR can have problems with the well itself. The landowner can be stuck with a hole that is hard to permit, hard to sell, and hard to fix.[1][4]

Counties and buyers' inspectors are not shy. A complaint from a neighbor is enough to start a file.

Do not try the "I only connected the pitless" story if you installed pumping equipment. The statute covers pump installation, more than turning a bit.

If you already did unlicensed work, stop and talk to a Colorado attorney who actually knows Article 91. This article is reference material from an independent publisher, not a law firm and not a service company.

I would not take a cash job "off the books" to build a portfolio. That portfolio is evidence.

How do you renew and stay compliant?

You renew on the board's cycle, pay the current renewal fee, and complete whatever continuing education the board currently requires. Confirm hours, approved courses, and deadlines with DWR. Those details change and I will not invent them.[1][4]

Stay compliant between renewals by building to 2 CCR 402-2, filing reports on time, drilling only what the permit allows, and keeping your bond in force.[5]

A lapse is not a cute paperwork gap. It is unlicensed work if you keep turning bits.

I would calendar the renewal 90 days out and keep CE certificates in the same folder as the bond. Boring. Effective.

If you add a crew, get your authorized individuals on the books the way the board wants, not with a verbal he-works-for-me. Compare that paperwork habit with how other states track helpers, including Arkansas, then still file Colorado's version.

Insurance is not the same as the statutory bond. Customers will ask for both. Price that into residential bids or you will work for free after the first claim conversation.

How do designated basins and exempt wells change the job?

If you only memorize the Board of Examiners exam, you will still walk into a bad bid on the eastern plains. Designated groundwater basins are administered with the Colorado Ground Water Commission, not only the familiar water-court story west of the divide.[9][10]

Exempt wells under C.R.S. § 37-92-602 are the ones homeowners ask about. Household use, often a 15 gpm cap, sometimes livestock or limited irrigation language depending on the permit. Non-exempt wells can require augmentation or other water-right paper that has nothing to do with how straight your casing is.[4][11]

Your license lets you construct. It does not manufacture a water right.

I'd decline a job where the owner says just drill it, we will permit it later. Especially in a designated basin.

CSU's Water Knowledge pages are a clean university map of well permits and administration if you need the water-rights half explained in plain language.[11]

Private wells stay outside EPA's Safe Drinking Water Act program when they serve a single home. That is why Colorado's construction rules and DWR files matter so much. There is no federal backup inspector for most household wells.[7][8]

Learn basin status before you quote mobilization. A cheap footage number on the wrong side of a designated-basin line is not cheap.

What first-year paper path would I actually run?

I would work in this order. Confirm each item against current DWR pages, because forms and fees move.

Get documented experience under a licensee, or prove what you already have. Read C.R.S. Title 37, Article 91 and the full 2 CCR 402-2 PDF, not a summary.[4][5]

Apply, bond, sit the exam. Do not buy a rig first.

Once licensed, pull the well permit before mobilization.[2][3] Read special conditions. Drill to the rule. Grout to the rule. Disinfect. File the construction report. If you set the pump, file that report too.

Price jobs from real geology, not a statewide rumor. Use CSU's private-well guidance when you explain testing and setbacks to a homeowner, then still follow the CCR.[6][7]

Keep a permit file, a grout and casing log, lab results, and the report PDF for every hole. Look at how other states ask for the same discipline, including Alabama, but file Colorado forms.

A pre-built board-and-log folder from WellDrillerPath is on /start if you want one. You do not need it to file a legal report.

That is the path. No national myth. No timing guarantee. Confirm fees, exam dates, bond amounts, and CE hours with the board before you spend.

Frequently asked questions

Can I drill my own well in Colorado without a contractor license?

Sometimes. Colorado's Article 91 path includes a narrow private-driller option for work on your own property. It is not a license to hire out, and you still need the well permit the State Engineer requires before most construction. Confirm the current private-driller limits with DWR. If a neighbor pays you, you have left that box.

Does a pump installer need a separate Colorado license?

Yes, pump installation for others is its own licensed activity under the Board of Examiners. Some people hold both a well construction ticket and a pump ticket. Confirm current categories on DWR's well construction pages. Installing pumping equipment without the right credential is still unlicensed work, even if you never turn a bit.

Do I need both a license and a well permit?

If you construct wells or set pumps for others, yes, you need the board license, and the well itself still needs a DWR permit in most cases. The license is about who may do the work. The permit is about whether that hole may exist and what it may pump. Starting either one late is how jobs stall.

How close can a new well be to a septic system in Colorado?

Setbacks live in 2 CCR 402-2, not in folklore. Distance to septic tanks, soil absorption systems, and other contamination sources is specified in the current rule text. Confirm the feet in the edition DWR is enforcing this year. CSU Extension explains why those distances exist for homeowners, but the CCR controls the job.

What is an authorized individual in Colorado well work?

An authorized individual works under a licensed contractor and may do specified tasks the board allows under that arrangement. It is a crew credential, not a company license. You cannot use it to bid your own jobs. Get the names on the books the way DWR currently asks, not with a verbal arrangement.

Where do I file a well construction report in Colorado?

You file it with the Division of Water Resources on the current official form, inside the time window 2 CCR 402-2 requires. Use today's PDF from DWR, not a glove-box copy. Keep your own copy of grout intervals, casing, and test data. Missing reports are a common way to get the board's attention.

Can an out-of-state driller work in Colorado on their home-state license?

Do not plan on a handshake reciprocity deal. Colorado expects its own board license for well construction and pump work done for others. Bring experience letters and plan to take Colorado's exam. Confirm any current endorsement or reciprocity language with DWR before you mobilize a rig across the line.

Does Colorado require continuing education for well drillers?

The board can require CE as part of renewal. Hours, approved courses, and deadlines change. Confirm the current requirement on DWR's licensing materials before you renew. I would calendar renewal 90 days out and keep certificates with the bond. A lapsed license is unlicensed work if you keep drilling.

What is 2 CCR 402-2?

It is the Code of Colorado Regulations series titled Rules and Regulations for Water Well Construction, Pump Installation, Cistern Installation, and Monitoring and Observation Hole/Well Construction. It is the statewide how-to for the hole, the grout, the pump, and the reports. The contractor license does not replace it. Read the current text, not a summary.

How do I check if a Colorado well driller is licensed?

Ask for the board license name and number, then confirm it through the Division of Water Resources well construction and licensing channels. Also ask for the well permit number before anyone mobilizes. A business card is not a credential. If they cannot produce both papers, keep looking.

Are private household wells regulated by EPA in Colorado?

No. EPA says it regulates public water systems and does not have authority to regulate private drinking water wells. The Safe Drinking Water Act does not run your single-home well. Colorado covers that gap with DWR permits, the Board of Examiners, and 2 CCR 402-2. Test water anyway. Construction quality still matters.

What is the 15 gpm limit I keep hearing about?

Many exempt domestic wells in Colorado are capped at 15 gallons per minute under C.R.S. § 37-92-602. That is a legal production cap on the permit, not a suggestion from the pump curve. Other well types and designated-basin permits can carry different limits. Read the actual permit before you select equipment.

Who enforces well construction standards in Colorado?

The Board of Examiners and the Division of Water Resources enforce contractor licensing and 2 CCR 402-2 construction standards. DWR also administers well permits. Designated basins add the Colorado Ground Water Commission on the water-rights side. EPA does not inspect your private household well. File the reports. Build to the rule.

How often does the Board of Examiners meet?

The board meets on its own published calendar, not on your bid schedule. Confirm upcoming meeting and exam dates on the current DWR board pages. Do not treat a blog post or an old minutes PDF as this year's schedule. I would not promise a customer a license-dependent start date until the board has actually acted.
