Nantucket outlines $44.8 million Somerset sewer plan; homeowners may face up to 25% betterments

Summary
Town officials and consultants presented the Somerset needs-area sewer extension, asking voters to appropriate $44.8 million for construction (plus $6.4 million already appropriated for design). Officials said SRF 0% loans are possible, but Article 15 authorizes assessing up to 25% in betterments or a sewer capacity fee; staff and residents pressed for clarity on hookups, grinder pumps and apportionment terms.
Town of Nantucket officials and their consultants laid out plans and costs on Monday for the Somerset needs-area sewer extension, telling residents the project would be financed in part by a $44.8 million construction appropriation in Article 15 at the May annual town meeting and could require property-level cost-recovery measures if adopted.
Consultant Dan Sheehan of Westin Samson said the sewer extension is intended mainly "to address nitrogen issues in the pond," citing 2004 and 2014 planning reports that identified septic-system nutrient loading and algal blooms in local ponds as the primary environmental drivers for the project. Sheehan described a mix of gravity sewer, low-pressure lines (requiring grinder or ejector pumps at some homes), a new pump station on Bartlett Road and related water-main, drainage and multiuse-path work.
The presentation shifted to project finance after the overview. Ryan Henley, also with the consulting team, said the town already appropriated $6,400,000 for design. The construction appropriation included in Article 15 is $44,800,000; if Article 15 passes at the May 4 town meeting, that amount and the earlier design appropriation would be included in the debt-exclusion ballot on May 19. Henley said the town applied to the Clean Water State Revolving Fund (SRF), which can offer 0% financing for nutrient-removal projects; the 2024 application failed but the 2025 submission placed the sewer portion on SRF's draft intended-use plan. "SRF eligibility requires the fund to be appropriated by 06/30/2026," he said.
Finance Director Brian Turbot clarified a point of active interest: the warrant language already contains authorization "to assess up to 25% of the sewer extension project cost on the owners of land to be served by the new sewers pursuant to the uniform unit method authorized under General Laws chapter 83," he said, noting the town may also use a sewer capacity fee or other enabling legislation. Turbot added the town would need a technical amendment to a citation in the warrant but said the motion’s text does include betterment authority.
Officials gave residents a range for typical homeowner impact. Henley estimated that assuming 25% of the sewer portion is assessed, a typical three-bedroom house would face roughly $20,000 to $25,000 in one-time costs; those costs could be apportioned over time. Turbot said either a sewer capacity fee or a betterment could be apportioned for up to 20 years and that the town has authority to charge "up to 2% above the rate that it has borrowed the funds at for the particular project," meaning a homeowner apportionment could carry an interest rate tied to project borrowing; he also warned that an apportionment is secured by a lien on the property for the life of the apportionment.
During the public question period, residents pressed for procedural and technical clarity. Daniel Murphy asked whether the town-meeting decision on May 4 requires a two-thirds vote; Turbot replied the Article 15 borrowing authorization requires two-thirds at town meeting while the May 19 debt-exclusion ballot is decided by a simple majority. Several homeowners asked whether multiple buildings on a parcel require separate connections; town staff said that separate septic systems must be abandoned and each dwelling connected, and that properties with separate buildings that could be subdivided generally require separate service connections. Sewer staff said they would confirm specific connection rules for accessory dwelling units and post the clarification in the project's Q&A before town meeting.
On operations and upfront costs, staff said properties in some areas (for example, Highbrush Path and Austin Farm Drive) will require grinder pumps; the town previously purchased grinder pumps for a prior extension and sold them to residents at a reduced rate, and the same approach is planned if feasible. The sewer-use base fee was described as roughly in the mid-$40s to $50 per month, including a base allotment; staff said the exact rate schedule is posted on the town water/sewer website.
Project timing remains contingent on the town votes and, if approved, external funding: Henley said bidding documents would go out in January 2027 with construction starting later in 2027 and lasting roughly two years, putting completion around 2029. If Article 15 does not pass this year, Henley warned the town would need to reapply to SRF in 2026 with no guarantee of selection.
The session closed with staff promising to post an updated public Q&A and maps on the project webpage, to hold another outreach session next week and to follow up with residents who raised detailed property-level questions.
