Renewing a Texas Class D wastewater operator license
Last reviewed 2026-08-01. Facts link to their official source.
Texas occupational licenses run three years, but Class D wastewater licenses cannot be renewed for operators at any activated-sludge facility, at trickling filter or RBC plants permitted at 100,000 gallons per day or more, or where subsurface drip dispersal is used. Where renewal applies, you need 30 hours of continuing education.
What renewal means for a Class D operator
A license runs three years
A Texas occupational license is valid for three years. Renewal is never automatic, and nothing here or at the TCEQ charges you on its own.
Many Class D licenses do not renew
For several systems and roles the TCEQ names, a Class D license cannot be renewed at all. Which situations apply to your track is set out in the sourced note below.
Where it renews, plan for continuing education
When renewal does apply, the TCEQ asks for 30 hours of continuing education. The sourced note shows the hours your track counts.
