Before any contractor touches your well or septic system, you have one easy check to run. It takes about three minutes and it tells you whether the person pulling up to your land is legally allowed to do what they're about to do.
On how to verify your well driller or septic installer is licensed in, J4 Water Works starts with the same rule: diagnose first, then quote the work. See our water well drilling for the well placement, casing, depth, and drilling work behind this guide.
Texas licenses well drillers and pump installers through one state agency and septic installers and maintenance providers through another. Each has an online lookup. This article walks you through both, explains what the licenses mean, and tells you what warning signs to watch for when you're hiring in this space.
Why Licensing Matters Beyond the Legal Requirement
Licensing isn't a piece of paper. The state requires it because drilling a water well incorrectly or installing a septic system wrong can contaminate groundwater, create health hazards, or leave you with a system that fails inspection and can't be permitted. An unlicensed contractor may save you money upfront. The repair costs, legal exposure, and permit problems that can follow are often significant.
Beyond your own property, groundwater is a shared resource. A poorly cased well can allow surface contamination to move into an aquifer that neighboring properties also draw from. Texas takes that seriously, which is why the licensing requirements exist and why enforcement has teeth.
Verifying a Water Well Driller or Pump Installer
In Texas, water well drillers and pump installers are licensed by the Texas Department of Licensing and Regulation, known as TDLR.
To check a license, go to the TDLR website and use their license verification lookup. You can search by the contractor's name, company name, or license number. The results will show you the license type, current status (active, expired, or suspended), and the expiration date.
There are different TDLR license levels for well work. An apprentice works under a licensed driller and is not authorized to run a job independently. A licensed driller can operate independently and take full responsibility for the job. Make sure whoever is heading your project holds the appropriate class of license for the work being done.
Ask any driller you're considering for their license number before you sign anything. A legitimate contractor gives it to you immediately, without hesitation. If someone gets evasive when you ask, that tells you something.
Verifying a Septic Installer or Maintenance Provider
Onsite sewage facility (OSSF) installers and maintenance providers in Texas are licensed by the Texas Commission on Environmental Quality, known as TCEQ.
TCEQ maintains a searchable database of licensed OSSF contractors. You can search by name, company, or license number. The lookup shows the license class, status, and expiration date.
TCEQ issues several different OSSF license types:
Class I Installer: licensed to install conventional septic systems
Class II Installer: licensed to install aerobic treatment systems, the most common type required in many rural Texas counties
Maintenance Provider: licensed to maintain aerobic septic systems under a service contract
Maintenance Technician: licensed to perform septic maintenance under a licensed provider
Apprentice: working toward licensure, must work under a licensed installer
If your property needs an aerobic septic system, confirm your installer holds a Class II license. If you're signing a maintenance contract, confirm the individual provider holds an active OSSF Maintenance Provider license. These are separate credentials and both matter.
J4 Water Works holds TCEQ Class I and Class II OSSF Installer credentials, an OSSF Maintenance Provider license, and OSSF Maintenance Technician credentials. We pull our license numbers on request, and they appear on every permit application we file. Our TDLR apprentice well driller and pump installer credentials are also current and on file.
What the Aerobic Maintenance Requirement Means for You
TCEQ says homeowners may perform maintenance on certain aerobic systems two years after initial installation, but local permitting authorities can require training or continued licensed maintenance. Check the permit and local authority before assuming the schedule. See TCEQ's current OSSF maintenance guidance. The contract obligates the provider to inspect the system on a set schedule and certify its operation to the county. Without a valid maintenance contract and a licensed provider on record, you may be out of compliance with your septic permit.
When you hire an installer for an aerobic system, ask whether they also offer maintenance contracts. Getting installation and ongoing service from the same company means one call for any question or problem, and one team that knows the full history of your system.

Warning Signs When Hiring in This Space
Licensing problems are more common in rural Texas than most people expect. Here are patterns worth watching for:
No license number when asked. This is the clearest signal. Any legitimate contractor gives you their number immediately. Hesitation or evasion is a reason to pause.
A license that's expired or suspended. An expired license means they've let their credential lapse. That's not necessarily fraud, but it is a compliance problem. A suspended license means something more serious happened. Both are reasons to ask more questions before signing anything.
A quote with no mention of permits. In Texas, wells and septic systems require permits. If a quote doesn't include permit costs or the contractor says they'll handle it without explaining how, ask directly whether they're pulling a permit. No permit means no inspection, and no inspection means no legal record that your system was installed correctly. More on permits in our permits for wells and septic in Texas.
No site visit before a firm quote. We cover this in detail in our questions to ask before you hire a well driller. A quote without a site visit is a guess. Anyone who gives you a firm price on a well or septic system without walking the land first is working on assumptions, not information.
Pressure to decide quickly or sign before you've verified credentials. Urgency tactics exist for a reason. Take the three minutes to run the license check before you sign.
Questions Worth Asking Any Contractor
What is your TDLR or TCEQ license number?
Is that license active and current?
Who will be on-site doing the work, and are they licensed or working under someone who is?
Will you pull the permit for this job?
Do you carry liability insurance and a bond?
Can you provide references from similar jobs in this county?
These aren't aggressive questions. They're basic due diligence. A contractor who gets defensive about any of them is telling you something useful.
Insurance and Bonding: One More Check
Beyond licensing, ask for proof of liability insurance and bonding. If something goes wrong during installation, you want to know the contractor carries coverage.
