    WOWRA has developed this two-day training course for onsite professionals to learn proper techniques for conducting evaluations of existing private onsite wastewater treatment systems. This innovative two-day training class, which concludes with a certification exam, will provide much-needed uniformity around the state, helping to reduce liability for those doing POWTS evaluations. The course will include both classroom instruction and field training. Please come prepared for outside conditions. Topics covered during the course include: POWTS Evaluator ethics and requirements; evaluator/client relationship and responsibilities; evaluation procedures (data collection through final reports); and procedures for evaluating recent, documented POWTS, as well as the “unknown” POWTS.  Upon course completion and passing the exam, you will receive certification as a WOWRA Certified POWTS Evaluator.
