Waterfront Septic Survey

Please provide a copy of any state approval or pre- or post- sale septic system evaluation not already noted on the map to the Town of Holderness (Land Use assistant). The risk score of each parcel on the waterfront septic map is based only on official records.  Once we verify that the public record has been updated the map will be updated with the revised score.

• Sunapee: Requires residents in the Lake Sunapee watershed to pump and inspect septic systems at least once every three years.

• Springfield: Requires regular septic pumping and inspection every three years for properties within 250 feet of protected water bodies or wetland buffer zones. 
• Newbury: Requires all residential properties to have septic tanks pumped at least once every three years (and annually for short-term rentals).
