Texas water operators are licensed by the Texas Commission on Environmental Quality (TCEQ). There are four classes, D (entry) through A (top). Each step up needs more training hours and more years of hands-on work. Here is how the ladder works and how to start.
Quick answers
How do I get a water operator license in Texas?
Texas licenses are issued by TCEQ. For a Class D water license you need a high school diploma or GED, the approved Basic Water Operations training and a passing exam score of at least 70%. No work experience is required. Then you log hands-on hours toward Class C, B and A.
What is the difference between a Class D and Class C license?
Class D is TCEQ’s entry license: diploma or GED, Basic Water Operations training and no experience. Class C needs two years of experience (one hands-on) plus track courses. In our Oct 30, 2026 data, Class D postings have a median of $22.23/hr (20 postings) and Class C $25.72/hr (20).
How much do water operators make in Texas?
On our board, the median posted pay is $23.33/hr (about $48,500/yr) across 59 Texas postings that list pay, as of Oct 30, 2026. By license: Class D $22.23/hr (n=20), Class C $25.72/hr (n=20), Class B $29.83/hr (n=13). BLS reports a May 2025 Texas median of $23.78/hr for SOC 51-8031.
Can I get hired without a license?
Some employers hire at entry level. Texas cities on our board, including Grapevine, Longview, Denison and La Marque, have posted apprentice or trainee operator roles. Whether a license is needed at hire, and how long you have to earn a Class D, varies, so check the original posting before you apply.

Step by step: your first license (Class D)
- Check the basics. You need a high school diploma or GED. No work experience is needed for Class D.
- Take Basic Water Operations. This TCEQ-approved course covers the required training hours. Check TCEQ’s list of approved training providers for current classes and formats.
- Apply to TCEQ and schedule the exam. Submit the license application and fee, then book your exam. You need at least 70% to pass.
- Get hired and log hands-on hours. Your experience clock for Class C starts now. Half of it should be in the specific field (surface water, groundwater or distribution) you want to license in.
- Keep it current. Licenses must be renewed with continuing education. Track your hours from day one.
Moving up: Class C, B and A
Class C is the working license for most Texas operators. On our board, Class C postings have a median posted pay of $25.72/hr versus $22.23/hr for Class D (posted pay, Oct 30, 2026). You need two years of experience (up to a year can be swapped for college credit or extra approved training) and the core courses for your track. Class B and A add years, management and lab courses, and they open up lead, chief operator and superintendent jobs.
Water vs wastewater licenses
TCEQ licenses drinking-water and wastewater operators separately. Wastewater treatment and collection have their own Class D to A ladder, with their own courses and exams. Some Texas postings, often at smaller cities, ask for one operator who holds both water and wastewater licenses.
