Wells & water in Water Mill: what's different here
Estates on Mecox Bay and the ocean lanes in the most expensive ZIP code on the South Fork, more than 60% of them counted seasonal, on outwash ground with the water table a few feet down, and the two working mills the hamlet is named for.
Water Mill has mains on the village streets and wells on the lanes and in the woods, and the plumber we send you to asks which before the truck rolls.
Outside the village centers the fuel is oil and propane; the water is SCWA on some lanes and wells on others, with iron and manganese in the well water that stains fixtures once treated, and nobody publishes the split. Water Mill is a hamlet of the Town of Southampton, permitted through the Building & Zoning Division in Hampton Bays, which publishes no plumbing page or fee line; the Town keeps mechanical equipment 10 feet from the property lines (8 feet in R-10) with screening.
Permits in Water Mill run through the Town of Southampton Building & Zoning Division in Hampton Bays; 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.
