Where to send your payment and what information you need

New York City water bills are issued by the Department of Environmental Protection (DEP). You can pay online through the DEP website, by mail, in person at a payment center, or by phone. The fastest route is online at nyc.gov/dep — you'll need your account number, which appears on your bill, and a bank account or debit card.

If you pay by mail, send your check or money order to the address printed on your bill. Include the stub from your bill so the payment reaches the right account. Mail payments take 7 to 10 business days to post, so send them early if you're near a due date.

In-person payment centers are located throughout the city. You can find the nearest one on the DEP website. Bring your bill or account number and cash, check, or money order. Phone payments go through an automated system at 311 or through a live representative — both accept debit or credit cards, though credit cards may carry a processing fee.

Key Takeaways

  • Online payment through nyc.gov/dep is the fastest method and posts within one to two business days.
  • Your account number appears on your bill and is required for any payment method.
  • Mail payments take 7 to 10 business days to post, so plan ahead if your due date is soon.
  • Late payments trigger a 10 percent penalty plus interest, and unpaid bills can result in a lien on your property.
  • If you cannot pay in full, contact the DEP to discuss a payment plan before your account falls behind.

Payment due dates and late fees

Water bills in New York City are issued quarterly — roughly every three months. The due date appears on your bill, usually 30 days after the bill is issued. If payment does not arrive by that date, the DEP adds a 10 percent penalty to your balance and begins charging interest at a rate set by the city each year.

The penalty and interest compound, meaning unpaid balances grow quickly. After 30 days past due, the DEP can file a lien against your property, which affects your ability to sell or refinance. If your bill remains unpaid for a longer period, the city can place your account with a collection agency or pursue a judgment against you.

If you receive a bill you believe is incorrect, contact the DEP's customer service line at 311 to dispute it. Disputes do not stop the clock on your due date, so pay the amount you do owe by the deadline while the dispute is being reviewed.

Setting up automatic payments or a payment plan

The DEP offers automatic payment through its website. You can authorize a monthly deduction from your bank account on a date you choose. This prevents missed payments and removes the need to remember due dates. To set up automatic payment, log into your account on nyc.gov/dep and select the autopay option.

If you cannot pay your full bill by the due date, contact the DEP before your account falls behind. The agency can set up a payment plan that breaks your balance into smaller installments over several months. Payment plans require you to stay current on new bills while paying down the old balance. Missing a payment on the plan can result in the full remaining balance becoming due immediately.

To request a payment plan, call 311 or visit a payment center in person. Have your account number and a sense of what monthly amount you can afford — the DEP will work with you to structure a plan that fits your budget.

What happens if you don't pay your water bill

Unpaid water bills have serious consequences beyond late fees. The city can shut off water service to your property if your account remains unpaid for an extended period. This is rare for residential customers but more common for commercial properties. Before shutoff occurs, the DEP sends multiple notices and offers opportunities to pay or set up a plan.

A lien filed against your property becomes public record and affects your credit. If you sell your home or property, the city can claim a portion of the sale proceeds to cover the unpaid water bill, penalties, and interest. If you refinance your mortgage, the lender will discover the lien during the title search and may refuse to proceed until it is paid.

Collection agencies may contact you by phone or mail if your account is referred to them. You have the right to dispute the debt in writing within 30 days of first contact. Even if you dispute it, you remain responsible for paying the original bill to the DEP — paying a collection agency does not satisfy your obligation to the city.

Payment options for people with low income

New York City offers a water rate reduction program for households that meet income limits. The program, called the Household Water Assistance Program (HWAP), reduces your water and sewer charges. Income limits and the amount of the reduction vary by household size and change each year.

To learn whether you may be may be able to access, contact the DEP at 311 or visit nyc.gov/dep. You will need to provide proof of household income, such as recent tax returns or pay stubs. The process takes several weeks, and the reduction applies to future bills once you are enrolled.

If you are behind on your water bill and have a low income, mention this when you contact the DEP about a payment plan. Some payment plans are structured more generously for households in financial hardship. The DEP also works with community organizations that provide bill payment assistance in certain neighborhoods — 311 can refer you to programs in your area.

Understanding your water bill and account number

Your water bill shows your account number in the upper right corner. This number is required for any payment method except in-person cash payments. The bill also lists your service address, the billing period, the amount due, and the due date. If you have multiple properties in New York City, each has its own account number and receives a separate bill.

The bill breaks down charges into water supply, sewer service, and sometimes stormwater charges. These are separate line items but are billed together. If you dispute one charge, you still owe the others by the due date. The bill also shows your meter reading and usage in hundred-cubic-foot units (HCF) — one HCF equals about 748 gallons.

Keep your bills and payment receipts for at least three years. If a payment is lost in the mail or misapplied to the wrong account, your receipt proves you paid. The DEP's online account portal lets you view your billing history, current balance, and payment status at any time.

Frequently Asked Questions

Can I pay my water bill with a credit card?

Yes, through the DEP website or by phone. Some payment methods charge a processing fee of 2 to 3 percent when you use a credit card, though debit cards and bank accounts do not. The website shows the fee before you complete the transaction.

What if I pay online but my payment doesn't show up?

Online payments typically post within one to two business days. If more than two business days have passed and your account still shows the old balance, contact the DEP at 311 with your confirmation number from the payment. Keep the confirmation email or receipt as proof.

Do I have to pay the full bill at once?

No. Contact the DEP before your due date to request a payment plan. You can arrange to pay your balance in installments over several months while staying current on new bills. Payment plans require you to make on-time monthly payments or the full remaining balance becomes due.

What if my water bill seems too high?

Call 311 to dispute the charge. The DEP will review your meter reading and usage history. Disputes do not stop your due date, so pay what you believe you owe while the review is underway. If the DEP finds an error, it will credit your account or adjust future bills.

Can the city shut off my water for not paying?

Yes, though it is rare for residential customers. The DEP sends multiple notices before shutoff and offers payment plans. If your account is severely past due and you have not responded to notices, shutoff becomes possible. Contact the DEP immediately if you receive a shutoff notice.
