Granite State Designers and Installers Association is New Hampshire's trade association for those working with on-site subsurface wastewater disposal systems. This website provides background about the organization and useful information for homeowners such as the care and maintenance of septic systems and how to find a qualified septic designer, installer, and evaluator.  Professionals will find links to all rules and laws concerning septic systems as well as a complete listing of a calendar of events.

 Thank you to all who attended our 31st Annual Spring Septic System Conference.  Shortly, we will be posting PDF handout versions of some of the conference sessions under the "Conference Resources" tab of this website.
