Superior Water Starts With You™
We're Raising the Standards for Water Treatment Safety through the Professional Operator Designation.
Water Professionals International (WPI) has been the global authority for professional certification of water and wastewater operators. For over 50 years, we have partnered with state, provincial and territorial authority water treatment certification programs to ensure that their water and wastewater operators meet the highest professional standards. With the introduction of WPI’s Professional Operator Designation, we are moving the industry towards a uniform set of standards and testing criteria for water safety professionals.
Professional Operators are recognized globally as the leading water and wastewater safety professionals.
Superior Water Starts With the Professional Operator Designation.
Although most jurisdictions administer operator certification programs to skilled professionals who keep our water sources safe and our environment clean, every state program is different. WPI’s Professional Operator Designation creates a global set of standards and testing criteria that reflect the best practices and protocols in the industry.
