A Look Back, A Look Forward

As we begin the slow melt of Spring, SESD is excited to announce the publication of our 2025 Annual Report, which highlights the achievements of all Divisions of the District for last year. Historical Annual Reports are housed in the Massachusetts State Library of Digital Collections dating back to 1937.

Last year, we reached our milestone 100th anniversary since our establishment by the Massachusetts Legislature Chapter 339 of the Acts of 1925. We are excited to engage with our communities in 2026 and have invested in a Centennial Plan to ensure another century of essential wastewater treatment and management services in our region.

You can learn more about SESD by attending local water quality events or school programs, attending one of our biannual Public Tours, or contacting us directly. We look forward to hearing from you and seeing you around the neighborhood!
