U.S. Veterans

Veterans are an excellent option for your workforce needs. We work with veterans to help translate their military water system skills into experience for Waterworks operator certification exams. Career Opportunities for Veterans in the Water Sector 331-471 (PDF).

Temporary Certification

A “temporary certification” helps water systems remain in compliance with certified operator requirements while the candidate is gaining the experience necessary to take a certification exam. Temporary certifications are limited in duration and only used when a water system's required certified operator position is vacant.
