Waterworks Operators

What's New

Annual renewals are now open.  Renew your waterworks certification before Jan. 21st to avoid a late fee.


The Department of Health (DOH) is responsible for administration of the Waterworks Operator Certification Program and the regulations, policies and guidelines established for certified waterworks operators.

Washington Certification Services at Green River College in Auburn manages both the Professional Growth and Certification Renewal programs through specific contract objectives. We follow the criteria established by the DOH in cooperation with the Waterworks Operator Certification Advisory Committee.
