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.
