We are excited to provide this informative web site as a service to our members and the public. The web site has a very easy to use search function to find members based on a zip code search, with access to members with the Certified Installer Onsite Waste Water Treatment Systems (CIOWTS) certification. You are able to preview and register on-line for upcoming training events. The site also allows you to sign up and pay your membership dues on-line.
