Drive down Teaticket Highway and you may still catch the same weekday closure that opened this spring: a stretch shut down between Sandwich Road and Maravista Avenue Extension while crews lay new sewer main. Town officials confirmed as recently as July that the work would continue straight through the summer rather than pause, to keep the broader project on schedule. The construction is visible. The number attached to it, for any individual property owner, still isn't.
That gap between what's physically happening in the ground and what shows up on a closing statement is the part of the Great Pond Phase 1 Sewer Project that matters most if you own, or are about to buy, a home on the Maravista or Teaticket peninsulas in East Falmouth. The project is real, funded, and under construction. The exact dollar figure each property will eventually owe has not been formally voted by the Select Board as of this year's spring meetings. Anyone transacting in this pocket of East Falmouth right now is buying or selling against an estimate, not a final number, and that distinction is worth more attention than it's gotten.
What's Actually Being Built, and Where
The project covers the northeastern corner of the Maravista peninsula and part of the Teaticket peninsula, an area the Town of Falmouth's project page describes as roughly 799 parcels. It's the first phase of a larger watershed plan the state approved in 2023 to pull nitrogen out of Great Pond, one of the town's most nitrogen-impaired water bodies. Construction contracts went out to bid in December 2025 and were awarded in February 2026, with a South Dennis firm, CC Construction, taking the largest contract at just over $16.7 million for the lift station and force mains. That lift station sits on Brick Kiln Road, on the same parcel where the town plans to eventually build its new police station. From there, wastewater travels by force main to the existing treatment facility on Blacksmith Shop Road.
Work started this spring and is scheduled for substantial completion by the end of 2027, with actual sewer connections likely available in late 2027 or early 2028. Once a property owner is formally notified that service is ready, the town gives them about a year to connect.
The Number Has Kept Moving Since April 2025
Falmouth Town Meeting authorized $60 million for this project in April 2025, and voters approved a Proposition 2½ debt exclusion the following month to help pay for it. Since then, the estimate has come down twice.
| When | Total Project Cost Estimate | Source |
|---|---|---|
| April 2025 | $60 million | Town Meeting authorization |
| January 2026 | approximately $52.4 million | Wastewater Superintendent Amy Lowell, construction bid update |
| May 2026 | $49.65 million | Select Board presentation on betterment allocation |
The most recent figure, presented to the Select Board on May 18, 2026, came in almost $10 million below earlier projections mainly because the collection-system bid landed well under the engineers' estimate. After factoring in an expected 25 percent loan forgiveness from the state's Clean Water Trust, the town's net cost is about $39.33 million. The portion assigned back to property owners as a betterment, roughly $14.74 million, is allocated across 848.25 sewer-equivalent units, or SEUs, which puts the current per-unit estimate at about $17,379. Paid over 30 years at 0 percent interest, that works out to roughly $579 a year per unit.
None of those figures are final. The Select Board has not yet voted the formal order of assessment. Property owners will get certified-mail notice with their specific SEU assignment before that vote happens, and the assessment isn't expected to actually appear on a tax bill until 2028. If you're closing on a home in this service area in the next year, you're working from a number the town itself still calls an estimate.
Same Service Area, Different Bill
The betterment isn't calculated on home value or bedroom count. It's assigned per SEU, tied to water use, which means the assessment tracks how much wastewater a property generates rather than what the property is worth. Two similarly sized homes on the same street can carry different SEU counts depending on fixtures and water consumption, and the town's policy assigns one SEU per residential unit for both single-family homes and condominiums, which changes the math again for multi-unit buildings.
The clearest example is the Falmouthport condominium complex, 210 units within the service area. A late design change removed any lift station or gravity sewer connection for that property entirely. Every unit there will connect through a grinder pump instead, a change that cut more than $2 million from the overall project cost. That's a materially different connection type, and potentially a different cost and maintenance profile, than a single-family home two streets over that gets a standard gravity hookup. The service area boundary on the map treats both the same. The engineering underneath it doesn't.
Ed Jalowick of the town's Water Quality Management Committee has been direct with owners about this variability, urging people to get multiple connection quotes and talk to a plumber early rather than assume a uniform cost. He's noted that his own connection bids varied significantly depending on site conditions. That's a useful caution for anyone assuming the betterment number is the whole story. The betterment covers the town's collection system. What it costs to actually tie your specific house into that system, trenching, grinder pump wiring, site restoration, is a separate expense that depends on your lot.
There's a related wrinkle worth knowing if you're near, but not inside, this exact service area. Falmouth adopted a local Title 5 supplement, FHR 15.15, effective November 15, 2025, requiring nitrogen-reducing septic systems for new construction or flow increases in the town's Nitrogen Sensitive Areas. Properties already inside an approved future sewer service area, like this one, are exempt from that separate septic mandate for now. Being inside the Great Pond Phase 1 boundary is, in that narrow sense, a temporary advantage over a similar lot just outside it.
What to Ask Before You Close
For anyone buying or selling inside the Maravista or Teaticket service area between now and 2028, a few questions are worth resolving before signing anything:
- Has the property received formal notification of its assigned SEU count, or is the number still an estimate pending the Select Board's order of assessment?
- Is the connection type gravity or grinder pump, and if grinder pump, is there a backup generator plan? The town has said homes with a generator powering the pump are unaffected during outages, while homes without one need to conserve water because grinder-pump tanks have limited storage.
- Does the betterment transfer with the parcel at sale, and has the current owner selected a payment method, lump sum or the 30-year installment plan, that a buyer would inherit?
- Is the home part of a multi-unit property like Falmouthport, where the condo association may coordinate connection costs rather than leaving it to individual owners?
None of these questions have a universal answer. They depend on where a specific parcel sits within the roughly 799 lots in this service area, and the town has said it will keep posting construction and assessment updates as the project moves forward.
The Same Math Is Coming for Acapesket
Phase 2 of this same watershed plan targets the Acapesket peninsula, just south of the current work. Its timeline depends on Falmouth securing a new ocean outfall permit for treated wastewater discharge, so it isn't running on the same clock as Phase 1. For anyone evaluating property further along Great Pond's shoreline, the Maravista and Teaticket rollout is a preview of the sequence to expect: town authorization, a betterment estimate that moves as bids come in, formal notification, and a tax bill that lands well after construction is finished.
If you're weighing a purchase or a sale anywhere near Great Pond, the sewer line on the map is only the start of the conversation. The number attached to your specific parcel is still being written, and getting it in writing before closing is worth the extra step.
