Some houses in Sag Harbor are on wells and the rest on the main, and the plumber for each is different. We put Sag Harbor homeowners in touch with one licensed, insured plumber who services pumps, tanks and treatment in Village of Sag Harbor, and we publish the national costs and what SCWA charges.

Wells & water in Sag Harbor: what's different here

Whaling-era captains’ houses with cast-iron drains and a hundred years of plumbers’ opinions, waterfront houses on the coves with basements at the water table, and a village that once drank from four dug wells and now runs its own wastewater plant.

Bayfront Sag Harbor is mostly on the main, with a high water table under the village and backflow devices on the meters; the plumber who works here knows which basements flood and where the expansion tank goes.

Sag Harbor is three-fifths in the Town of Southampton and two-fifths in East Hampton along Division Street, 2,772 residents at the 2020 Census, with seasonal homes estimated at about 36% of its housing (a low-confidence figure) and a rental registry that sets a 30-day minimum with two 14-day exceptions a year. The Village’s Building Department issues building permits, electrical work applications and sign permits and their inspections; plumbing is not named separately on its page, so a water heater or boiler is a building-permit conversation with the inspector.

Permits in Sag Harbor run through the Village of Sag Harbor Building Department inside the village; the Towns of East Hampton and Southampton beyond the village line; the plumber we put you in touch with handles the filing where one is required.

FAQ

Wells & water questions

Is my Hamptons house on a well or town water, and does it matter?

Look in the basement: a meter and a Suffolk County Water Authority bill means the main; a pressure tank, a pump switch and no bill means a well. Nobody publishes the share of South Fork houses on each, and both are common east of the village centers. It matters in four ways. Cost: SCWA charges $1.866 per hundred cubic feet, $34.33 a quarter and a $20 water-quality charge; a well costs the pump ($975–2,821 to replace) and the power. Water: South Fork wells commonly run iron and manganese that stain fixtures once treated, and Long Island drinks from the sole-source aquifer under it either way. Winter: a well pump stops when the power does. Lead and PFAS: SCWA is replacing lead service lines by 2030 with an address checker, and treats PFAS with granular activated carbon; a well is the owner’s to test.

How do I winterize my Hamptons house?

Heat it or drain it, and tell someone. Heated: leave the thermostat at 55°F or more — the insurance industry’s “reasonable care” standard for an unoccupied house, and the fact pattern a 2024 New York court case turned on — open the cabinet doors under the sinks, insulate the exposed runs, shut and drain the outdoor lines, and put a Wi-Fi freeze alarm (from about $25) on the boiler and a smart shutoff ($579.99 for the one we could price) on the main. Drained: a plumber shuts the main, drains the supply lines, water heater, traps and outdoor lines and adds antifreeze; no Long Island company publishes the price, so ask. The pipes will see 15.7°F at Islip’s design temperature, and a burst costs $200–3,000 to fix and $1,000–4,000 in damage.
