TCEQ Wastewater Operator License CEU Requirements: What You Need by License Class

ComplyFlo · November 2, 2026 · 5 min read

Standard renewable Texas wastewater treatment and collection licenses need the same 30 hours of continuing education to renew, and those hours must be finished before the license expires. The total is the same for treatment Classes A, B, and C, for eligible Class D licenses, and for collection Classes I, II, and III. What changes by class is which courses count and whether the license can be renewed at all. ComplyFlo tracks each operator's CE progress and license expiration so the deadline does not arrive unnoticed.

A note on scope and units. Provisional Class D licenses are different: they are valid for two years and must be upgraded to Class D or higher, rather than renewed on the three-year cycle. TCEQ states the renewal requirement in continuing-education hours, so this guide uses CE hours when describing the required total.

TL;DR: Standard renewable wastewater treatment and collection licenses require 30 CE hours per three-year renewal. Provisional Class D follows a separate two-year upgrade path. Class A and B operators cannot count Basic Wastewater Operation. Class D is not renewable at certain facilities. CE must be completed before expiration, even if you use the 180-day application window.

How many CE hours does a Texas wastewater operator license require?

Thirty CE hours per three-year renewal, for standard renewable wastewater treatment and collection system licenses (TCEQ). The total does not change with your class. CE hours are awarded only for successful completion of TCEQ-approved training courses.

Two timing rules matter as much as the total. The hours must be earned before your license expires, and they may be earned at any point during the three years the license is valid (TCEQ). You can check your current hours on TCEQ's License Information webpage.

Does the CEU requirement change by license class?

The 30-hour total does not change by class, but the rules around which courses count and whether a license can be renewed do (TCEQ).

Why can't Class A and B operators count the basic course?

Because TCEQ excludes it from renewal credit. Class A and B wastewater operators may not apply the Basic Wastewater Operation course, or any course equivalent to it, for renewal credit hours (TCEQ).

Class A and B operators must obtain their renewal credit from eligible TCEQ-approved courses other than Basic Wastewater Operation or its equivalents. Self-paced and correspondence courses also may not be repeated for CE credit within the same renewal period (TCEQ).

When is a Class D license not renewable?

Class D is not renewable for operators at three facility types (TCEQ):

• any activated-sludge treatment facility, at any size,

• qualifying trickling-filter or RBC facilities with a permitted average daily flow of 100,000 gallons per day or greater,

• a wastewater facility that disposes of treated effluent through a subsurface area drip dispersal system.

An operator at one of those facilities must hold the license class the facility requires, rather than renewing the Class D. Check TCEQ's license-level table to confirm the minimum class for your plant.

Can you still renew a TCEQ wastewater license by exam instead of CEUs?

No. Effective March 23, 2025, wastewater treatment operators and wastewater collection operators can no longer renew by examination in lieu of completing CE hours (TCEQ). Standard renewable license holders must earn the 30 CE hours.

Special provisions may apply to qualifying military service members. TCEQ allows renewal within two years of returning from active duty outside Texas, and waives the required CE for the cycle the licensee served on active duty (TCEQ).

When must the CE hours be finished, and what happens if you miss?

Before your license expiration date. TCEQ states that CE must be completed before the license expires, and that failing to complete the required hours by the expiration date results in denial of the renewal application, regardless of when it is submitted during the 180-day grace period (TCEQ).

House Bill 1237, effective September 1, 2025, allows up to 180 days after expiration to submit the renewal application, with additional fees. That window does not extend the deadline to finish the CE hours (TCEQ).

Whether you may keep working while a renewal is pending turns on when you submitted the renewal application and fee, not simply how many days have passed.

If you submit the renewal application and fee during the first 90 days after expiration, processing that extends beyond day 180 does not by itself disqualify the application. The applicable continuation provision allows licensed activities until TCEQ renews or denies the license.

As a courtesy, TCEQ emails a renewal reminder about 90 days before expiration and mails one about 60 days before, to your address on file (TCEQ).

The CE deadline falls before expiration. An application received or postmarked within 180 days is reviewed on its own track, and a timely application is not disqualified because review continues past day 180.

How does manual CEU tracking compare with ComplyFlo?

Manual tracking relies on a calendar, a spreadsheet, or a search of TCEQ's license records one operator at a time. ComplyFlo keeps every operator's license date and CE progress visible to the whole team (ComplyFlo).

What does ComplyFlo do for operator licensing?

ComplyFlo tracks wastewater operator license classes, expiration dates, and CE progress, and can also track operator-in-training personnel (ComplyFlo). A live progress bar per operator lets administrators see who is on track and who needs hours before their renewal window. It is a tracking layer, not a training provider. Operators remain responsible for completing approved training, confirming their CE record, and submitting the renewal.

Frequently Asked Questions

How many CE hours do Texas wastewater operators need to renew?

Thirty CE hours per three-year renewal cycle, for standard renewable wastewater treatment and collection licenses. Provisional Class D follows a separate two-year upgrade requirement (TCEQ).

Can Class A and B operators count the basic course toward renewal?

No. Basic Wastewater Operation and equivalent courses do not count toward renewal credit for Class A or B. Those operators must use eligible TCEQ-approved courses other than that course or its equivalents (TCEQ).

Does the 180-day late window give me more time to earn CE hours?

No. All CE hours must be finished before the license expiration date. The 180-day window covers only submitting the renewal application, and it does not extend the CE deadline (TCEQ).

Can a Class D license always be renewed?

No. Class D is not renewable for operators at any activated-sludge facility, qualifying trickling-filter or RBC facilities, and subsurface drip-dispersal facilities. Those operators must upgrade to the class the facility requires (TCEQ).

What if I miss the 180-day late-renewal application deadline?

If your renewal application is not received by TCEQ or postmarked within 180 days after expiration, ordinary renewal is unavailable. You must submit a new application, meet current education, training, and experience requirements, and pass the applicable examination. An application submitted within the allowed period is different from waiting until afterward to apply. Special military-service provisions may apply (TCEQ).
