CWT currently offers two publications (shown below) to assist water and wastewater designers and operators in the design of process improvements and the operation and evaluation of existing facilities.

Operators planning to take water and/or wastewater certification exams will find these references valuable in preparing for for the process and math related problems typically given on these exams.

These publications can also be used in the classroom by water and wastewater system trainers as a primary reference or a supplemental reference for process and math courses.
