PRESERVING A RESIDENTIAL LAKE COMMUNITY WITH ALL-TERRAIN SEWER
Perkins Pond, Sunapee, New Hampshire
Challenge: A Community Needed to Protect its Lake from Failing Septic Tanks
Perkins Pond, located in Sunapee, New Hampshire, has approximately 100 homes with 30 occupied year-round. The desire to sewer the homes dated back the 1970s, but conventional gravity sewer was cost-prohibitive. Residents knew that as septic tanks would eventually fail and pollute the lake.
Solution: A Cost-Effective Sewer System
The Perkins Pond Protective Association wouldn't give up: they worked to get a sewer vote on the ballot and even when the vote failed, they created a plan to communicate the need to residents. Eventually sewers were approved and both pressure sewer and gravity systems were reviewed.
Terrain around Perkins Pond is hilly. A gravity sewer system would have required several lift stations, adding significantly to the project costs. Pressure sewer cost about half that of gravity sewer and didn't require the same number of lift stations — approximately $1.5 million for pressure sewer vs $3 million for gravity sewer.
Result: No Fear when Flushing
After the pressure sewer system was installed, residents celebrated with a "flush party" — they no longer needed to worry about their septic tanks filling up or leaching into the lake.
