Onsite Wastewater Training Seminars

Our septic seminars are a fun, one-day, six-credit continuing education program.

Onsite Wastewater Professionals can earn continuing education credits, required by the State of Wisconsin, in one day at an Onsite Wastewater Training Seminar sponsored by Wieser Concrete.

Seminars qualify as six (6) credits toward Wisconsin’s continuing education requirement and feature informational sessions, and industry vendor displays showing the latest onsite technologies.

Attendees will also have an opportunity to network with industry and regulatory professionals.

We Need Your Help!

Did you attend one of our seminars this year?

We would love to hear back from you on how it went so we can improve for next year. This 5-minute survey is open to anyone who attended. All responses are anonymous so please enter your info if you wish to be contacted by a representative or be entered into the gift card drawing. You will only be contacted if you request it on the form or if your name is drawn. We have concluded the random drawing (Congrats to Lara!). However, we still value your feedback on the seminars if you wish to take the survey.
