Online Training & Certification:


In Virginia, certification is required for all designers and installers. The classes are a great way to learn more about our product, even if you are not seeking certification. We strongly recommend regulators involved in the review and inspection of Advanced Enviro-Septic® systems take the certification training.

As part of certification, an assessment test is required. This should be taken only after viewing the class videos and reading the Virginia Design and Installation Manual. The test is open book and is not timed. A passing score of 70% is required for certification.

Four hours of Continuing Professional Education are available from VA DPOR Board for Waterworks and Wastewater Works Operators and Onsite Sewage System Professionals.
