Water Treatment Design Course - Self-Study

*The course must be purchased under the userID of the person who will be taking the course.

**A 3% convenience fee will be charged at the time of purchase

The Water Treatment Design Course is a self-paced training opportunity for technical in-office staff, technical support staff, engineers and others to learn about water contaminants and treatment solutions. The course addresses contamination behavior, drinking water regulations, POU/POE treatment technologies and their application and sizing. 

The course is a pre-requisite for the Certified Treatment Designer title. 

The first three of four modules may also be completed as instructor-led courses in the CWS program. Please check the Education page at wqa.org for upcoming classes and make sure to select the CTD-path options when registering.
