Approved Continuing Education Seminars

A consolidated list of approved continuing education courses for septic designers and installers for license renewal (RSA 485-A:35&36).

These courses are not hosted by NHDES, unless specified, and all questions about the courses themselves should be addressed to the course hosts directly.

Within the two-year renewal period, permitted septic designers and installers must complete a minimum of six credit hours of continuing education approved by NHDES.

Attention: Within a single renewal period, permit holders will only be given credit for attending a course once. If a permit holder takes an identical course multiple times in a single renewal period, they will not receive any additional credit after the first instance. Permit holders are allowed to retake courses in subsequent renewal periods and will be given full credit during that period.
