Septic License Requirements in Texas
We all need safe, reliable sewage management for our homes and businesses. Those homeowners and businesses that rely on septic tanks, also known as on-site sewage facilities (OSSF), depend on people who know how to install and maintain those systems. Everyone, in every community, needs those professionals to have the expertise to protect the environment from the inherent contaminants.
In Texas, OSSF are the systems of choice for about 20% of new homes, according to the Texas Commission on Environmental Quality (TCEQ) and about 45,000 OSSF are installed annually acording to the Texas A&M AgriLife Extension.
There are 30,650 septic tank servicers and sewer pipe cleaners nationwide, according to the Bureau of Labor Statistics (BLS) and 2,430 in Texas. Nationally, employment is projected to grow 8% from 2024 to 2034, adding about 2,900 openings each year. In Texas, the outlook is even stronger, with a projected growth rate of 28% for septic tank servicers and sewer pipe cleaners, according to CareerOneStop, the U.S. Department of Labor's job search website. If you're thinking about starting a business in this field or you want a job in it, you need to know the requirements in your state or local jurisdiction. This guide will help you determine what you need before you get started.
Types of Septic Licenses in Texas
To operate as an OSSF installer, apprentice, maintenance provider or maintenance technician in Texas, you must be licensed or registered by the TCEQ. There are different parameters of work permitted for each license and different requirements to obtain each.
Installer I License
The holder of an Installer I license is authorized to install standard OSSF systems (septic tanks, absorptive drainfields, unlined ET drainfields, leaching chambers, gravel-less pipe, and pumped effluent drainfields).
Applicants for Installer I must complete OSSF-approved training through TEEX (Texas A&M Engineering Extension Services) before applying to TCEQ. Upon approval, you will need to pass the related exam. No previous educational or work experience is required.
Installer II License
The holder of an Installer II license is authorized to install all types of OSSF systems. Applicants for Installer II must complete OSSF-approved training through TEEX (Texas A&M Engineering Extension Services) and must have worked as either a licensed Installer I for at least a year or a Registered Apprentice for at least two years and provide the necessary documentation before applying to TCEQ. Upon approval, you will need to pass the related exam.
Apprentice Registration
An OSSF apprentice is authorized to represent the supervising installer at the job site. However, apprentices may only perform OSSF installation services under the constant, direct supervision of a licensed installer, either on-site or by radio or other means of direct communications. If supervision is not on-site, the licensed installer must visit the job site at least once each workday to verify the work of the apprentice is being performed in accordance with State or Authorized Agent requirements. No previous educational or work experience is required.
Maintenance Technician Registration
A registered Maintenance Technician is authorized to perform services associated with OSSF maintenance but only under the direct supervision and direction of the maintenance provider either on-site or by direct communication with the maintenance provider.
Applicants must complete approved training through TOWA (Texas On-site Wastewater Association) before applying to TCEQ. No previous educational or work experience is required.
Maintenance Providers License
Licensed Maintenance Providers are authorized to provide service or maintenance to on-site disposal systems using aerobic treatment. Applicants must complete approved training through TOWA (Texas On-site Wastewater Association) and must have previous work experience as follows:
Possess a current OSSF Installer II license; or
Possess a Class C or higher Wastewater Treatment Operator license; or
Have three years of experience as a registered Maintenance Technician.
Applicants must provide the necessary documentation before applying to TCEQ. Upon approval you will need to take and pass the related exam.
The other OSSF-related license is an OSSF Site Evaluator license and it is granted only in addition to other licenses—never as a standalone license. To hold this license, an individual must hold a concurrent license of one of the following types; Designated Representative, Installer II, Professional Engineer, Professional Sanitarian, Professional Soil Scientist. Application for an OSSF Site Evaluator license requires an affidavit affirming that the individual holds a current license in one of these designations.
Steps to Get a Septic License in Texas
The steps to getting any of the septic licenses listed above are similar with variations in the required training, work experience, and tests.
Complete license-specific training course.
Meet specific work experience when required (OSSF Installer II and Maintenance Provider).
Apply to TCEQ, completing the appropriate application packet and pay the application fee.
Meet criminal history requirements, including fingerprinting.
Upon approval from TCEQ, take computer-based tests when required (OSSF Installer II and Maintenance Provider).
Pass the exam when needed and receive your license.
Renew license every three years after completing continuous education (CE) requirements when needed and pay the renewal fee.
Benefits of Getting a Septic License in Texas
There are many benefits to getting a septic (OSSF) license in Texas.
First, and most important, it is illegal to operate as an OSSF installer, apprentice, maintenance provider or maintenance technician in Texas without being licensed or registered by the TCEQ.
A license is proof of your experience and skill in the industry.
Only licensed professionals can operate a business and advertise OSSF services and perform them.
Having a license protects your company and customers.
Licensing gives you a competitive advantage in the job market.
It also increases your earning potential.
What Is the Mean Wage for a Septic Professional in Texas?
The annual mean wage for septic tank servicers and sewer pipe cleaners nationwide is $53,500, according to the Bureau of Labor Statistics. In Texas, the median annual wage for this occupation is $43,860, or about $21.09 an hour.
Pay rises with experience and skill. In Texas, the lowest 10% of these workers earn about $34,670 a year, while the top 10% earn about $64,380, according to the BLS. Owning a licensed OSSF business, holding a higher-level license such as Installer II or Maintenance Provider, and adding certifications can all push earnings toward the upper end of that range.
The difference between a mean wage and a median salary can be confusing. Here is the distinction:
Mean wage tells you the mathematical average.
Median salary tells you the point at which 50% of workers earn less and 50% earn more, and is usually a better indicator of what most people actually earn.
Salaries can vary widely depending on the city where you work and factors like experience, certifications, additional skills, and whether you own the business.
How Much Does It Cost to Get a Septic License in Texas?
Getting a septic license in Texas can cost up to about $600-$700.
The cost will depend primarily on the required training. The OSSF application fee for each of the licenses/registrations is $111 to be paid to TCEQ.
Apprentices don’t need any additional training, so the registration fee is the only expense.
The Installer I Basic Training course offered through TEEX is $460 in Mesquite and online and $465 in San Antonio, Bryan, and online.
The Installer II Basic Training course through TEEX is $560 in Mesquite and online and $565 in San Antonio, Bryan, and online.The Maintenance Technician Basic Maintenance Provider course offered through TOWA is only held in San Marcos and has a $355 fee.
The Maintenance Providers License requires two courses—Basic Maintenance Provider (BMP) and Advanced Aerobic Maintenance Provider (AMP)—offered through TOWA. Both are held in San Marcos except where noted. The fee for BMP is $355 as noted above. AMP costs $525.
There is also a fee associated with the computer-based testing, but it varies by exam center location. The fee to renew all licenses and registrations is $111 every three years. There are also continuing education courses required for Installer I & II and Maintenance Providers.

How to Get a Septic License in Texas
There are no educational or work experience requirements to get started as a septic professional in Texas if you begin as an apprentice working for a licensed professional. To do that legally, you will need to apply for Apprentice Registration through the TCEQ. There is an online portal to submit your application for registration. The application fee is $111. There is no testing required and no license-related documents are required for an apprentice registration. Once registered, you may begin working for a licensed professional on the types of septic systems that he or she is authorized to install or repair.
You may also begin your journey in the field with an Installer I License. Again, there are no minimum educational or work experience requirements, but for an Installer I License you will need to take an approved OSSF training course. The course is Installer I Basic Training and is offered through TEEX at the Mesquite, San Antonio, and Bryan campuses and online. After successfully completing the course, you will need to apply for an Installer I License through TCEQ and pay the $111 application fee. Again, no license-related documents are required to apply for Installer I, but you will need to pass a computer-based test to receive your license.
You may work indefinitely with an Installer I license as long as you meet the continuing education requirements and renew your license every three years. That Installer I license only permits the holder to work on standard OSSF systems.
An Installer II License allows the holder to work on all kinds of OSSFs, including aerobic systems. If you wish to pursue this less-restrictive license you will not only need to apply to TCEQ and pay that same $111 application fee, but you will need to pass two courses through TEEX and provide documentation proving a minimum amount of work experience in the field. There are two ways to demonstrate the experience needed:
Hold a current Installer I License for at least one year and submit either a sworn statement for OSSF I to OSSF II verifying at least three installations from either a designated representative who approved the installations or from three individuals for whom the applicant performed construction services or other documentation approved by the executive director of TCEQ.
Hold an apprentice registration for at least two years and submit either a sworn statement for Apprentice to OSSF II verifying at least six installations from either a designated representative who approved the installations or from six individuals for whom the applicant performed construction services or other documentation approved by the executive director of TCEQ.
Upon approval from TCEQ, you must pass a computer-based test at one of the exam locations throughout Texas.
The other path you may pursue is a Maintenance Technician Registration and Maintenance Providers License. Just like an Apprentice Registration, there are no educational or work experience requirements to begin as a registered Maintenance Technician. Once registered, you may perform services associated with OSSF maintenance but only under the direct supervision and direction of the maintenance provider either on-site or by direct communication.
Applicants must complete approved training through TOWA (Texas On-site Wastewater Association) before applying to TCEQ and paying the $111 application fee. There are no continuing education requirements to renew your registration.
A Maintenance Provider License requires more training and work experience. To get this license, you will need to complete two courses of approved training through TOWA. You will also need to either hold a current OSSF Installer II license, a Class C or higher Wastewater Treatment Operator license, or have three years of experience as a registered Maintenance Technician.
Applicants must provide the necessary documentation before applying. Upon approval from TCEQ, you will need to pass computer-based testing at one of the exam locations throughout the state. Licensees must complete 24 units of continuing education to renew every three years.
How Long Does it Take to Get a Septic License in Texas?
Obtaining a septic license in Texas can take from a few months to a few years, depending on which license you are seeking. The Apprentice or Maintenance Technician Registration can be accomplished quickly as there is no required training, so it’s simply a matter of applying and waiting for your registration to be issued. To qualify for an Installer II License, it can take more than two years; for a Maintenance Provider License, it can take more than three.
Texas Septic Training Programs and Schools
Because the Texas Commission of Environmental Quality specifies which training programs are approved for each license, there is not a lot of choice as to where to attend. As mentioned above, for either of the Installer licenses you will need to complete training at the Texas A&M Engineering Extension Services (TEEX). OSSF Installer I and OSSF Installer II classes are offered through Texas On-site Wastewater Association (TOWA).
Texas Septic Licensing Exam Details
As part of the process to receive your Installer I, Installer II, or Maintenance Provider License, you will need to pass a computer-based test (CGT) through TCEQ. These examinations are designed to demonstrate that applicants have a grasp of the information needed to perform the various jobs. They are offered at testing centers throughout the state. These are closed-book, computer-based exams—septic candidates may not bring training manuals, notes, or electronic devices into the testing room. All examinations have a three-hour time limit. Pre-approval of your license application is required for testing. For pre-approval, applicants must complete licensing requirements including education, work experience, and training and submit an application through the website using the online application— Occupational Licensing Electronic Application (OLEA).
Everything you need to prepare for the TCEQ licensing examinations is on the website. The website encourages applicants to study the most current training materials from all of the required training to prepare. According to the site, “the testing fees are established by each CBT center and may vary based on the center. CBT exams at TCEQ-approved test centers provide immediate exam scores and exam analysis feedback. Some test centers may offer one immediate retest on the same day.”

How Can I Prepare for the Septic License Exam in Texas?
The TCEQ recommends studying the most current materials from your required OSSF training course, since the exam draws questions from that curriculum and from the state rules that govern on-site sewage facilities.
OSSF licensing exams are closed-book. Under the TCEQ's computer-based testing rules, only Municipal Solid Waste Supervisor candidates may bring reference materials, so septic applicants may not bring books, notes, cell phones, smart watches, or other aids into the testing room. Approved test centers deliver the exams on-screen, and candidates receive an immediate score and printed exam analysis. Some centers offer one immediate retest on the same day.
To study effectively, review your Installer I, Installer II, or Maintenance Provider course manual, work through practice questions on the equipment and system types the exam covers, and get familiar with the computer-based testing format before test day.
Do I Need to Renew My Texas Septic License?
All septic licenses and registrations in Texas must be renewed every three years. There are requirements for renewal. Also, detailed information can be found on another page of the website.
To be eligible for renewal, applicants must:
Complete the continuing education requirements—24 CE credit hours for each Installer I, Installer II, and Maintenance Provider Licenses.
Submit a renewal application and criminal history attestation.
Pay the $111 renewal fee.
Only TCEQ-approved training courses will be accepted for continuing education and must be completed before the current license expires. You can check your current CE hours earned by searching the License Information webpage.
TCEQ strongly encourages licensees to keep their contact information up to date, so you will receive courtesy reminders when your license is up for renewal. Renewal notifications will be mailed to the last known address on file at least 60 days before the license expires. If there is an email address on file, an email notification will be sent 90 days before the license expires.
Texas Septic License Exceptions
There are few exemptions from the OSSF Licensing rules in place in Texas. Those exemptions are spelled out in the Texas Administrative Code (TAC). It states that only owners of a single-family dwelling are not required to be a licensed installer to install or repair an on-site sewage facility (OSSF) on the individual's property. The code is very clear that this provision does not apply to property that is to be developed for sale or lease. It also specifies that if the property owner compensates a person to construct any portion of an OSSF, the individual performing the work must be a licensed installer.
Who Issues Septic Licenses in Texas?
Licensing for septic installers for the entire state of Texas is under the authority of the Texas Commission on Environmental Quality (TCEQ). The TCEQ has all the information you need on its website, including requirements for licensing, training providers, and learning how to get a new license, a renewal, or even a replacement license or registration. You can also register to take an exam, and find training and continuing education courses.
The TCEQ delegates authority to local governments for on-site sewage facility permits. OSSFs must be designed on the basis of a site evaluation that accounts for local conditions and are only for domestic sewage—never industrial waste. This is all spelled out in the Texas Health and Safety Code.
According to the TCEQ website, “The sudden increase of new housing in suburban and rural areas means that more Texas households depend on an OSSF for treatment and disposal of domestic sewage. In recent years, many new systems have been permitted, most in high growth areas of the state. New approaches to design and overseeing OSSFs ensure systems do their job properly and protect the environment. Almost all OSSFs must have a permit prior to any construction, installation, repair, extension, or other alteration. Any work on an OSSF must be performed by a licensed installer or directly by the homeowner when it is their single-family residence. If someone is paid for any part of the process, that person must be licensed by the state.”
The TCEQ website also explains that, “In most areas of the state, local authorities have taken on the responsibility for ensuring that OSSFs in their area comply with all state requirements.” Many local governments have taken on the responsibility of being “authorized agents” (AA) of the Texas Commission on Environmental Quality for administering the OSSF Program. Residents can search for their local permitting authority online and must submit a permit application before installing an OSSF system.
Does My Texas Septic License Work in Any Other State?
No, a Texas OSSF license does not automatically transfer to another state. States regulate septic and on-site wastewater licensing individually, so if you move or want to work elsewhere you will need to apply for a license under that state's own rules. Some states may accept your Texas license and experience as proof of eligibility to test or apply, but each state's licensing authority makes that call. If you plan to keep working in Texas while occasionally taking jobs across state lines, confirm the requirements with the licensing agency in the other state before you perform any paid work there.
Does Texas Reciprocate Septic Licenses?
Yes, Texas does reciprocate septic licenses. You can apply for a septic license through reciprocity in Texas, and the TCEQ may waive qualifications, training, or an examination for a license on a case-by-case basis. According to the website, to be eligible you must have a current license from another state, territory, or country, have taken an exam to receive the license, and have a good compliance history, and currently be in good standing with the licensing authority that issued the license.
When applying by reciprocity, you can still apply online. Just be sure to enter all of the information under the reciprocity section and upload a copy of your current license, and copies of any applicable training or course completion certificates.
National Septic Certifications
Other certifications can help you demonstrate your proficiency to potential employers and clients. The National Association of Wastewater Technicians and The National Onsite Wastewater Recycling Association offer certifications. Those and other professional certifications are not required but can add to your marketability and therefore increase your opportunity to make more money. You can also learn more about certification and the septic business in Texas through one of the industry associations in the state. They include:
American Backflow Prevention Association Texas Chapters — Central Texas, Corpus Christi, Lower Rio Grande Valley, North Texas (DFW Area), San Antonio
Other Requirements Unique to Texas
While septic licensing authority in Texas rests with the TCEQ, permitting authority for OSSFs rests with local jurisdictions—cities, counties, towns—and they determine some of the maintenance rules for these systems. Some permitting authorities allow homeowners to perform maintenance, but others are adopting more stringent rules surrounding who can perform these maintenance tasks. In some cases, authorities may require homeowner training before being allowed to maintain systems or even prohibit homeowners from doing it themselves at all. Homeowners are encouraged to contact their local permitting authority. You can search for that contact information by clicking this link.
Are There Septic Scholarships in Texas?
Yes. The Texas On-Site Wastewater Association (TOWA) funds scholarships each year for members and their families, including the Ron Suchecki Memorial Scholarship and general scholastic scholarships supported by the association's annual conference fundraisers. Applications are typically due in the spring, and TOWA announces the awards at its annual conference.
If you plan to take septic or wastewater coursework through a Texas community or technical college, you may also qualify for state and federal aid. Start by completing the Free Application for Federal Student Aid (FAFSA), then check your college's financial-aid office and the Texas Workforce Commission for training grants and workforce scholarships tied to high-demand trades.
How Can Someone Verify My Septic License in Texas?
Anyone can confirm the status of a Texas OSSF license or registration through the TCEQ's online License Information search. Homeowners, employers, or authorized agents follow these steps:
Open the TCEQ License Information search page.
Search by the license holder's name, license number, or license type (for example, Installer I or Maintenance Provider).
Review the results to confirm the license is active, the level of licensure held, and any continuing-education status on file.
Because the TCEQ is the agency that issues and enforces these licenses, its lookup tool is the authoritative way to confirm that a septic professional is currently licensed to work in Texas.
When Can a Septic License Get Suspended in Texas?
The TCEQ can suspend or revoke an OSSF license or registration, or deny an application, when a licensee violates the rules that govern on-site sewage facilities. Under the TCEQ's occupational licensing rules, the executive director must notify the individual in writing of the intent to suspend or revoke. Common reasons for suspension or revocation include:
Fraud or deceit in obtaining, renewing, or applying for a license.
Certain criminal convictions related to the practice of the profession.
Violations of OSSF construction, installation, or maintenance standards.
Work or supervision outside the scope of your license, or aid to unlicensed individuals.
A lapsed license, or failure to meet renewal and continuing-education requirements.
Note: The information above is not legal advice. For the specific rules, refer to the TCEQ's official OSSF rules compilation.
What Are the Penalties for Unlicensed Septic Work in Texas?
Performing paid OSSF work in Texas without a license is illegal. Under the Texas Health and Safety Code, Chapter 366, a licensed installer must perform any work on an on-site sewage facility, unless a homeowner does the work on their own single-family residence. Anyone paid for any part of the process must hold a state license.
The TCEQ enforces these requirements and can pursue administrative and civil penalties under the Texas Water Code, Chapter 7, including monetary penalties for each violation. The agency can also seek a court injunction to stop unlicensed work, and criminal penalties may apply in some cases. Working without a license can also jeopardize your ability to obtain a license later.
Note: The information above is not legal advice. For the specific statutes, refer to the Texas Health and Safety Code, Chapter 366.
Continuing Education
The Texas Commission on Environmental Quality requires continuing education for all septic licenses except Apprentice Registrations and Maintenance Technician Registrations. All other OSSF licenses require 24 hours of Continuing Education (CE) for renewal. You can find a list of approved training providers here.
