At a Nov. 16 Special Town Meeting, Carlisle voters will decide whether to fund Article 6, listed as Town Center Wastewater Connection Engineering and Design. The proposal is tied to efforts to reopen the shuttered general store, Ferns, and to address wastewater concerns in the village center.
Article 6 appears among the Special Town Meeting warrant articles as Town Center Wastewater Connection Engineering and Design, according to the Town of Carlisle. Carlisle has no municipal sewerage or town water system, leaving every home and business, including Ferns, dependent on private wells and septic systems. As The Boston Globe reports, that reliance on small lots, aging septic tanks and closely packed wells has become a defining fault line in a town otherwise known for its preserved Colonial character.
A 180-Year-Old Store Stuck Without a Bathroom Plan
Ferns served as Carlisle's village-center general store for more than 180 years before closing in 2025, according to The Boston Globe. Ben and Amy Pirri signed an exclusive option contract that year to buy and reopen the property, envisioning a café and community gathering spot with a full kitchen and indoor and outdoor seating. The Globe reported that the property had been using a composting toilet because it lacked room for a conventional septic leaching field without risking nearby wells.
A restaurant architect toured Ferns in August 2025. The nearby police station's septic system was also found too small to handle Ferns' wastewater.
An Engineer's Case for the School Plant
A feasibility analysis by Weston & Sampson evaluated a limited connection to the wastewater plant at Banta Davis Field, which serves the public school. The plant, permitted for 13,500 gallons per day, handles 3,000 to 4,000 gallons per day during heavy use and could accommodate Ferns' estimated design flow of 2,145 gallons per day, according to the Ferns Carlisle update. The proposed pipeline would run roughly 2,100 feet from Ferns to the plant, according to The Boston Globe.
Contamination Alarms Across the Village Center
Water-quality scares have piled up at exactly the properties town leaders now want to connect. In September 2021, testing found E. coli and coliform contamination in Ferns' 84-foot-deep well. MassDEP instructed that a temporary chlorination system be installed, and a seal on the bedrock casing was removed after the water supply proved inadequate. The Globe separately reports contaminant alarms at Town Hall, the library and the school.
Carlisle sits atop fractured bedrock that can speed the movement of wastewater from septic systems toward nearby wells, according to the Globe's reporting, a geological reality environmental researcher Susan Murcott has warned could turn the sewage problem deadly within the next few decades, per the same account. The Ferns property itself carries an added environmental wrinkle: the site at 18 Lowell Street was once home to Daisy's Gasoline Station and remains monitored by the state under MassDEP Release Tracking Number 3-2578 following past petroleum releases from underground tanks, according to the Town of Carlisle.
A Disputed Spike and a Push for a Sewer Committee
The push toward a town-wide fix accelerated after Ben Pirri paid for his own study, after the Select Board declined to fund or subsidize a $55,700 analysis he had requested, according to the Globe.
The Globe reports resident concerns about housing and Carlisle's character amid the debate. The Select Board has since directed Ben Pirri to form a sewer committee that includes a representative from nearly every other town committee, according to the Globe.
Grants, a Second Vote and a Wealthy Town's Reckoning
Ferns Carlisle says the requested funding includes grant applications. Officials have structured the decision into two votes: the Nov. 16 Special Town Meeting warrant article covers design and permitting, with a second vote planned for early 2027 to approve final construction funding, the same source states.
Earlier Groundwater Planning
Carlisle has also pursued a separate effort to improve its understanding of local groundwater. According to the Town of Carlisle, the Carlisle Underground Study received a grant in fall 2023 and completed its final memo and maps in June 2026. The study focused on groundwater mapping and planning data, not the sewer connection proposed in Article 6.
The debate is unfolding in Carlisle. Whatever voters decide on Nov. 16, the outcome will shape not just whether Ferns reopens after more than 180 years as the village's general store, but how — and whether — Carlisle addresses a wastewater problem that is not new.
