TX Wastewater Treatment Operator CE Hour Requirements

The short answer

30 CE hours every 3 years. Every wastewater license TCEQ issues, at every class.

Texas is one of the states where grade doesn't change the number. A Class D operator and a Class A operator both owe 30. What grade changes is which courses count — see "Courses that don't count for you" below.

Your cycle

Your license is good for three years from the day it was issued, so Texas has no statewide renewal date. Your expiration date is your own; check your pocket card or the TCEQ license search.

Hours only count if you earned them after your current license was issued and before it expires. Training from your last cycle doesn't roll forward, and neither does anything extra — Texas has no carryover. Thirty-six hours in one cycle is thirty for this renewal and zero toward the next.

TCEQ mails a renewal notice at least 60 days out and emails one at 90 days if they have your address. Those are courtesies, not your deadline. You can't file more than 90 days early.

The thing that catches people: the 180-day window is not extra time for training

Since September 1, 2025, you can file a renewal application up to 180 days after your license expires:

Read the next part carefully, because it's the part that costs people their license:

That window does not move your CE deadline. All 30 hours have to be done by the expiration date on your license. If they aren't, TCEQ denies the renewal — it doesn't matter whether you filed on day 2 or day 179.

Two more lines on the same clock:

• If you've submitted your application and you're 90 days or less past expiration, you can keep doing licensed work while it's processed. Past 90 days with nothing filed, you can't.
• Past 180 days, there's no renewal at all. New application, current requirements, and you sit the exam again.

And one option that's gone: as of March 23, 2025, you can no longer retake the exam instead of doing your CE. Older guides still say you can. They're out of date.

What counts

Any TCEQ-approved course, in any approved delivery method — classroom, conference, webinar, online, correspondence. TCEQ approves the provider and the course and assigns the hours; providers list their approved courses and hour values on TCEQ's training page.

There are no category minimums on the wastewater side. No technical/non-technical split, no safety cap, no management requirement. Thirty approved hours is thirty approved hours.

The 2-hour resiliency training requirement is for water licenses only — you don't need it. But resiliency courses carry both water and wastewater credit, so if you take one it counts toward your 30.

The repeat rule

You can't repeat a distance course for credit inside the same renewal period. Online self-paced and correspondence courses you've already been credited for in this cycle earn nothing the second time. If you're topping up in the last few months, check what's already on your record before you buy the same course again.

Courses that don't count for you

If you hold Class A or Class B wastewater treatment: Basic Wastewater Operation, or any course equivalent to it, earns you no renewal credit. That includes the correspondence and online versions and the Sacramento State volumes that map to it — providers flag these. Take it anyway if you want the refresher, but it won't count.

Class D operators — check your plant

A Class D license can't be renewed at all if you're the operator at:

• any activated-sludge-type facility, of any size;
• a trickling filter or RBC facility permitted at 100,000 gpd or more; or
• a facility that disposes of treated effluent through subsurface area drip dispersal.

If your plant is upgrading, the CE isn't your problem — the class is. Plan the upgrade to Class C or higher before your expiration date.

Does Texas track your hours for you?

Mostly, yes. Approved training providers have to report your completed hours to TCEQ electronically within 14 business days, and you can see your running total on TCEQ's license information search at www2.tceq.texas.gov/lic_dpa/.

Two gaps worth knowing about:

1. The 14-day lag is real, and it's a reporting duty on the provider, not on you. A course finished the week your license expires may not be on your record when TCEQ looks. Keep the completion certificate.
2. Class A and B operators can self-certify. TCEQ has a continuing education attestation form: you sign that you're in compliance with the CE requirement, and that's the verification. It doesn't ask for documentation. Falsifying it is grounds for denial or for revoking your license, so if you sign it you want your own file of certificates behind it — TCEQ's record may not have every hour you're attesting to.

The attestation isn't a shortcut around the renewal itself. You still file the renewal application, the criminal history attestation, and the fee.

What we couldn't confirm

Two things, and we'd rather say so than guess:

• If you hold more than one wastewater license — say a treatment class and a collections class — we could not find a TCEQ source stating whether you owe 30 hours total or 30 for each. Credit in Texas is awarded by program category, which suggests wastewater-approved hours may serve both, but nothing we located says so. Ask TCEQ Occupational Licensing at licenses@tceq.texas.gov before you plan a cycle around it.
• How long you have to keep your certificates. The five-year retention rule we found applies to training providers. We found no rule setting a retention period for licensees. Practically: keep them, especially if you self-attest.

Also worth knowing

• Renewal fee is $111 on time.
• Update your address with TCEQ within 10 days of a move — it's a rule, and it's how the renewal notice reaches you.
• Military service members outside Texas get the CE waived for the cycle they were on active duty, and up to two years after returning to renew.
• TCEQ has a rulemaking in progress to conform Chapter 30 to the 2025 legislation (hearing September 9, 2026). The 180-day window is already in force by statute; the rule text is catching up.
• An ethics-training requirement was petitioned for in 2024 and TCEQ decided not to adopt it. If you see it mentioned, it didn't happen.

Water vs wastewater

Same agency, same chapter of rules, same 30 hours, same three-year term. If you hold a water license too, the differences are: water requires at least 2 of the 30 hours in approved resiliency training, and Class A/B water operators can't count Basic Water Operation. Otherwise it's the same program.
