Required Certification Information for California Employees

A field operations classification with Cal Water Service requires a valid certification. A valid certification renewal is due 4 months before the certification expires. To avoid late fees, mail your renewal forms and fees by your renewal due date. If you do not fulfill the renewal process before the certification expires, you will be placed in a Laborer Group 3 position until your certification is renewed and received by Cal Water Service.

Visit the State Water Resources Control Board for renewal information. If you have any questions, please contact the Drinking Water Operator Certification Program at (916) 449-5611
