Climate Resiliency Committee Meeting - July 21, 2026

The Marlborough MA Climate Resiliency Committee met on July 21, 2026, to discuss potential climate-related infrastructure projects, focusing primarily on a thermal energy exchange initiative involving wastewater heat recovery. The committee explored the feasibility of applying for a $15,000 state grant to conduct a feasibility study for this project, which aims to provide heating and cooling to affordable housing developments by capturing thermal energy from wastewater. Black Swan Labs representatives explained the phased grant process, including subsequent design and construction funding opportunities up to $750,000. Committee members debated the city's role as a utility broker, funding mechanisms, and the technical and financial feasibility of the project. A motion was made and later retracted regarding proceeding with the grant application, with consensus to await the feasibility study results before committing further resources. The committee also discussed scheduling future meetings and the possibility of a referendum ballot in 2027, with a recommendation to consult the city solicitor before proceeding. Overall, the meeting centered on advancing the thermal energy project cautiously, leveraging state grants, and ensuring alignment with city resources and priorities.
