How can I get a copy of my septic design?

If it is on file with the City, you can call Development Services at 692-9520 and a member of the staff can help you and they may be able to provide a photocopy of the plan. There will be a charge of 50¢ per page for the copies. If it is not on file, you will have to contact New Hampshire Department of Environmental Services Subsurface Systems Bureau at (603) 271-3501 or contact the original designer of the system.
