Renewals occur every two years and are due by December 31 of odd-numbered years. The 2023 renewal forms will be mailed out the first week of September.  The renewal fee is $75.

All active Massachusetts wastewater operators are required to provide proof of 20 training contact hours (TCHs) during a given renewal period.  Please do not send in your training proof until you get an invoice.

Certification renewal invoices for current operators include TCH credits earned through NEIWPCC, NEWEA, or MAWEA for training completed through June 30, 2023. To receive credit for any class not listed on your individual invoice, submit a copy of the training certificate along with your renewal invoice.  Your renewal notice will be mailed to you the first week of September.

All ACTIVE operators need 20 TCHs for the renewal from the period of January 1, 2022 through December 31, 2023.  Newly certified ACTIVE operators in 2022 require 20 TCHs and, if newly certified in 2023, 10 TCHs are required.
