Water and Sewer Charges at Closing in NYC, Westchester and Long Island: Final Readings, Liens and Who Pays

In New York, an unpaid water or sewer bill from a government supplier is usually a lien on the property. That means it stays with the house, not just with the person who used the water. So title companies check water and sewer charges on every purchase, and unpaid amounts are paid out of the seller’s proceeds at closing.

In New York City, city law makes the bill a lien. In Westchester and on Long Island (Nassau and Suffolk counties), it depends on who supplies the water. Villages, water districts, the Suffolk County Water Authority and sewer districts can add unpaid charges to the property tax bill. Private water companies bill only the customer.

Timing matters too. Water is billed after it’s used, so the last bill rarely runs to the closing date. A final meter reading closes that gap. Without one, the title policy does not cover water charges after the last actual reading.

Who bills water and sewer, and whether it becomes a lien

Supplier Lien on the property?
NYC DEP / Water Board Yes, until paid
Village water Yes; added to the tax bill
Town water district Yes; added to the tax bill
City water department Depends on the city’s own law
Suffolk County Water Authority Yes; added to the tax bill
Government sewer rents Yes; added to the tax bill
Private water company No law found making it one; it’s a customer account

Water and sewer charges in New York City

Why NYC water bills are a lien

In the five boroughs, the Department of Environmental Protection (DEP) bills water and sewer charges for the New York City Water Board. Under city law, taxes, assessments, sewer rents and water rents, with interest and charges, stay a lien on the property until paid. DEP says Water Board bills, even ones based on “estimated reads,” are “considered a ‘lien’ against your property until they are paid in full” (DEP, Water and Sewer Bill FAQs).

The NYC final meter reading (“title read”)

DEP calls the closing reading a Property Transfer Meter Reading, or title read. The rules are in the Water Board rate schedule effective July 1, 2026. The schedule also makes the property owner legally responsible for all charges.

  • The request must be made before the sale closes, by email (TitleReadRequests@dep.nyc.gov), at a borough office, by phone or by mail.
  • DEP charges a $25 Title Read Fee to the property.
  • DEP issues a Title Read Letter within 30 days of the request, or within 10 days of a field inspection if one is needed.
  • The letter is good for 60 days after it’s issued.
  • If the sale is arm’s length (between unrelated parties), as shown on the transfer tax form, DEP won’t later raise charges for any period before the letter.
  • That protection doesn’t apply if the customer kept DEP from reading or inspecting the meter.

A request made after the sale gets an Off-Cycle Reconciliation Letter instead, and DEP may later adjust those charges up or down. DEP’s FAQ is blunt. Without a title read done at least 30 days before closing, a new owner is “not protected from un-issued charges that may date back to consumption of the prior owner” (DEP FAQs). The reading does not shut off service (NYC 311).

What the title search shows, and who holds money back

Since May 22, 2020, DEP gives search companies only account numbers and current balances, not usage history. One underwriter’s 2022 New York guidelines set two rules for the attorney on a purchase. The attorney must get the Title Read Letter before the closing is scheduled. The closing must then happen within 15 days after the letter is issued. Otherwise, the guidelines treat the policy as not covering unbilled or back-billed charges (Stewart Title, New York Guidelines). These are one underwriter’s instructions, not a universal rule.

The same guidelines say the title company should hold back only charges that have been billed and are still open. For usage since the last actual reading, the title company gives the parties the date and amount of that reading. The buyer and seller then set their own holdback, which the guidelines say is “usually between $500-$1000.” That holdback is a contract matter, usually held by an attorney.

Estimated bills, frozen meters and buildings without meters

Most NYC meters report automatically, and most customers are billed quarterly. When DEP can’t get a reading, it sends an estimated bill based on past usage. It asks owners not to let more than three estimates in a row go by without contacting it (DEP FAQs; DEP, Water Meter FAQs). A run of estimates before a sale is exactly what the title read is for.

Owners must protect meters from freezing and damage, and an outdoor meter pit must be insulated. DEP won’t do a title read for an account in its denial-of-access process (Water Meter FAQs).

A property without a meter or remote reading device pays a yearly surcharge equal to 100% of its last annual unmetered charge, back to July 1, 2000. Stewart’s guidelines call for money to be held in escrow on an unmetered property until a meter is installed or the surcharge is billed.

Buildings with four or more units may be on the Multi-family Conservation Program. It charges a flat yearly amount per unit instead of metered billing. The balance still has to be paid.

Water and sewer debt in the NYC tax lien sale

The City can sell unpaid water and sewer charges in its tax lien sale. Whether a property qualifies depends on its type (DOF, Lien Sale Eligibility Chart; DOF, Lien Sales):

  • One-family home owing only water and sewer: no lien can be sold.
  • Two- and three-family homes: qualify at $3,000 unpaid for one year.
  • Most other property types: qualify at $1,000.

Water and sewer liens were about $29 million of the $220 million sold in 2025. The City will not hold a sale in 2026 (NYC Independent Budget Office, April 2026). A sold water lien is paid to whoever holds the lien, not to DEP. How sold liens show up and get paid off is covered in the property tax lien sale guide.

Water and sewer charges in Westchester

Westchester has 100 community public water suppliers (Westchester County Department of Health). They include:

  • city water departments, such as Yonkers and White Plains
  • village systems and town water districts
  • Westchester Joint Water Works (Mamaroneck, Rye and Harrison areas)
  • private companies such as Veolia (formerly SUEZ); the state Public Service Commission approved its acquisition of the company in December 2021 (NYS Public Service Commission)

Your supplier decides the lien rules and how final readings work.

Unpaid bills added to the tax bill. For village water, unpaid water rents become a lien that comes ahead of all other liens except existing tax liens. The village board can add them to the yearly tax bill (state village law). For town water districts, water charges are a lien, and unpaid amounts go on the tax roll under “Water Rents” (state town law).

Cities follow their own laws. White Plains, for example, doesn’t shut off water for nonpayment. Instead, unpaid charges “are re-levied against your property as a tax lien on the subsequent July 1st” (City of White Plains FAQ). Once added to the tax bill, a charge shows up on the tax search, not the water search (see Westchester municipal searches).

Final readings. Each supplier sets its own process and fee:

  • White Plains charges $75 for a final reading (City of White Plains FAQ).
  • Yonkers bills its six water districts twice a year. It issues a final bill on request the day before or the day of closing (City of Yonkers, Water Bills).
  • Town of Cortlandt doesn’t require one but notes that sellers’ attorneys do. It adds a $45 fee to the bill (Town of Cortlandt).
  • Westchester Joint Water Works takes requests by form. It asks for at least three full business days’ notice, plus one more business day to prepare the bill (WJWW, Final Meter Read).

Private water companies. We found no law making a private water company’s bill a lien on the land. Outside NYC, where water is private, Stewart’s guidelines call for a final water bill paid at closing or a sworn statement (affidavit) about it. Without a final reading, the policy keeps its standard water exception.

Water and sewer charges on Long Island

Nassau water districts and villages. Much of Nassau gets water from special water districts and village systems. Examples are the Jericho Water District (NYS Comptroller audit) and the Roslyn Water District. Village water follows the same state village law described above.

Some districts send unpaid charges to the town to collect on the tax bill. In the Roslyn Water District, for example, bills unpaid from June 30 through August 31 go to the Town of North Hempstead for the general tax bill. The district warns that if the final bill isn’t settled at closing, “the new owner will be responsible for past water usage” (Roslyn Water District, buying a home).

Suffolk County Water Authority (SCWA). Since 2016, unpaid SCWA charges are a lien on the property served, ahead of all liens except taxes and assessments (state law). Each year by November 1, SCWA sends the list of accounts 90 or more days behind to the town tax receiver. The receiver adds the amounts to the tax roll under “water charge.”

Private water companies. Liberty Utilities serves parts of Nassau. The Public Service Commission approved its purchase of New York American Water in December 2021 (NYS Public Service Commission). As in Westchester, its bills are customer accounts, handled at closing with a final bill or affidavit.

Sewer bills and sewer rents

Sewer charges come either as a district tax on your property tax bill or as a separate sewer rent. When a city, village, town or county charges sewer rents, unpaid rents become a lien. It comes ahead of everything except an existing tax lien, and unpaid rents go in a separate column of the tax roll (state law).

  • Nassau County. The county sewer district tax is part of the county general tax bill, based on taxable value (Village of Sea Cliff, Nassau County Sewer District Taxes). It’s cleared with the tax search, not by a meter reading.
  • Suffolk County. On January 1, 2026, the county’s sewer districts merged into the Suffolk County Wastewater Management District. Sewer charges no longer appear on the property tax bill. The district bills homes quarterly, and unpaid charges are liens. Amounts billed before August 1 and unpaid on October 1 go on the town’s December 1 tax bill as sewer arrears. The district isn’t told about sales and says charges and credits “transfer with the property” (Suffolk County DPW, Sewer Billing Services). Town and village sewer districts in Suffolk bill separately.
  • Westchester. Sewer can be a district tax line or a usage charge on the water bill. Yonkers, for example, charges $1.38 per 100 cubic feet for sewer (City of Yonkers).

How title insurance treats unpaid water charges

Unpaid water and sewer liens found in the search become closing requirements and are paid at closing. Title reports also list standard exceptions (things the policy won’t cover). One underwriter’s guidelines list two. One covers “taxes, tax liens, tax sales, water rates, sewer rents and assessments as set forth in the Tax Search.” Unless a final reading is obtained, another covers water charges since the last actual reading. The claim examples guide walks through a missed water charge.

There is also a gap between closing and the day the deed is recorded. The standard New York endorsement to the owner’s policy does not cover a government water charge or sewer rent that becomes a lien during that gap. The loan policy has the same gap, running to the recording of the mortgage. The exclusion reaches only charges “imposed by governmental authority.” The endorsements guide covers the rest of the endorsement.

Who pays at closing

By custom, the seller pays charges through the final reading, from the seller’s proceeds. The money goes to the supplier, or to the lien holder for a sold NYC lien. The buyer pays for usage after the reading.

The contract sets how partial-period bills are split and how much is held back. Some suppliers, such as Suffolk’s sewer district, won’t split a bill. In a foreclosure sale, the referee pays water and sewer charges that are liens from the sale proceeds; see liens surviving a foreclosure sale.

Details for attorneys and title professionals

  • Where to find each rule. The Water Board rate schedule and Stewart’s guidelines are long documents. Their Official sources entries list the section behind each rule described above.
  • Lien statutes. The lien and tax-roll rules in the table come from five laws. NYC water: the NYC Administrative Code. Village water: the Village Law. Town water districts: the Town Law. SCWA: the Public Authorities Law, through a 2016 amendment. Sewer rents: the General Municipal Law. No statute was identified for Nassau special water district relevies; the Roslyn example is that district’s own practice.
  • Endorsement wording. The Standard New York Endorsement (March 8, 2024 form, printed in the TIRSA Rate Manual) replaces one of the owner’s policy’s printed exclusions with this wording: “Any lien on the Title for real estate taxes, assessments, water charges or sewer rents imposed by governmental authority and created or attaching between Date of Policy and the date of recording of the deed or other instrument of transfer in the Public Records that vests Title as Shown in Schedule A.” The loan policy version makes the same change to a matching loan policy exclusion and runs to recording of the mortgage. The exclusion numbers are in the TIRSA entry in Official sources.
