Onsite Sewage interpretation update
I have mailed out membership renewals. I had an accident October 2, 2025 and have not been my best. So some of the renewals go back to November 2025.
If you want to pay for two years (an extra year to catch up), want to restart or want to discontinue your membership, please note it on the form.
It is too late to order books so the fall courses are cancelled due to non participation!
Our hours are 9 to 5 Monday to Friday. We are not open on holidays.
