At its September 2, 2026 meeting, Mashpee’s Board of Health held a second discussion of changes to its rules for I/A septic systems, which remove nitrogen. Today, new construction and rebuilds within 1,000 feet of water must use systems that reach 19 mg/L of nitrogen. The proposal would require I/A systems for all new construction and extend the rules to wellhead protection areas, which cover about a third of the town. Properties within 500 feet of surface water would face a stricter 11 mg/L limit.
A CPWB representative, a Monomoscoy Island resident, Select Board and Planning Board members and others urged the board to act or to go further. The health agent said urine diversion is allowed if kept inside the home, but an I/A system would still be needed for other wastewater. A vote was planned for October 7, and the state must also approve the rule.
