Online Renewal Instructions - Please Read Carefully!

Drinking water system operators can now renew and pay for their operator certification online with MyLicense​! The online renewal process is for individual renewal and credit card payment (using MasterCard or Visa only). 
  • You will need a credit card, MasterCard or Visa 
  • You will need your renewal notice with your assigned personal PIN# and operator certification number. ​
    Note: The certification number must be entered in the form "D-1234" or "T-1234" as appropriate. Do not forget to enter the dash in the certification number
  • Once you have registered, you can change your log-in and password
  • Instructions for using MyLicense are on each screen, as well as details letting you know about the next step.
  • Individuals holding two operator certificates must renew and pay for each separately; after renewing one, you will be redirected to renew the second certificate.
  • If your credit card payment is declined by the online system, you will need to submit your renewal notice and check by mail to Drinking Water Services (See mailing instructions below).
  • At any time during the year you can update your address and telephone number through MyLicense online!
PLEASE NOTE: Renewing operator certification is the responsibility of the operator, not the operators manager, secretary, or family member.
