Site work for a water / sewer project in Exeter, New Hampshire. Conceptual plans call for site work for a water / sewer project.

This project would include the installation of a new biosolids drying unit at the wastewater treatment facility to reduce the amount of water within the biosolids by-product that is generated by the treatment process. The Town disposes of its biolsolids by trucking them to an approved landfill or biolsolids re-use processing facility. Currently, these biosolids are comprised of approximately 20-25% solids and 75%-80% water. Drying the biosolids could increase solids content up to 80% (20% water) and significantly reducing disposal costs. Based on 2022 disposal tonnages and fees, it is estimated that the Town could reduce disposal costs by $150,000 to $180,000 per year. Pending PFAS regulations and limited landfill space are anticipated to to impact the re-use and disposal of biosolids in future years. The project is included in the City's 2026-2031 Capital Improvement Program (CIP). As of November 5, 2025, further details have not yet been identified. *Project information has been obtained through a public capital improvement plan (CIP).
