Phase 1
Sewer Expansion Projects
Currently the Town is implementing Phase 1 (Years 0-10) of the Comprehensive Wastewater Management Plan (CWMP). Phase 1 consists of 18 individual sewer collection system projects, and additional sewer extensions, that will result in roughly 90 miles of new sewer infrastructure. Once complete, Phase 1 will remove approximately 44% of the nitrogen impacting our waters.
