How to Pay Your Baltimore Water Bill

How to pay your Baltimore water bill online, by phone, or by mail

Baltimore's water bill is managed by the Department of Public Works, and you can pay it through their official website, by phone, through the mail, or in person at a payment center. The fastest method is online at baltimorecity.gov/water, where you can pay when ready with a bank account or debit card. If you prefer not to go online, you can call 410-396-5398 during business hours, mail a check to the address on your bill, or visit a payment location in person.

Your water bill arrives monthly and shows your account number, the amount due, and the due date. Keep your account number handy when you pay — you'll need it whether you're paying online, by phone, or by mail. Payments made online or by phone usually post within one business day, while mailed checks take longer depending on postal delivery time.

Paying online through the Baltimore water website

The Department of Public Works website is the quickest way to pay. Go to baltimorecity.gov/water and look for the "Pay Your Bill" or "Make a Payment" link on the homepage. You'll enter your account number (found on your bill) and the amount you want to pay. The site will then ask for payment details — either your bank account information for an electronic check or your debit card number.

Online payments are processed when ready, though it may take up to one business day for the payment to show on your account. There is no fee for paying with a bank account, but some payment processors charge a small fee if you use a debit card — the website will show you any fee before you confirm. You'll receive a confirmation number on screen and by email, which you should keep for your records.

Paying by phone with the Department of Public Works

Call 410-396-5398 during business hours to pay over the phone. A representative will ask for your account number and the amount you want to pay, then process your payment using your bank account or debit card. Phone payments are treated the same as online payments and post within one business day.

Have your bill and payment method ready before you call. The representative will give you a confirmation number — write it down. Phone lines can have wait times during peak hours, so calling early in the morning or mid-week may be faster.

Paying by mail

Write a check or money order payable to "Baltimore City" and mail it to the address shown on your water bill. Include your account number on the check itself. Mail payments take longer to post because they depend on postal delivery and processing time — typically one to two weeks or more from the date you mail it.

Do not send cash through the mail. If you're paying close to the due date, mail is not a reliable method because delays can result in a late payment even if you mailed the check on time. For bills due soon, use online or phone payment instead.

Paying in person at a Baltimore payment center

You can pay your water bill in cash, check, or money order at several locations around Baltimore. The main payment center is located at 200 Holliday Street, Baltimore, MD 21202. Some neighborhood locations also accept payments — check the Department of Public Works website for the full list of payment centers and their hours.

In-person payments post when ready or within one business day. Bring your account number and your bill if possible, though the staff can look up your account if you provide your address. Payment centers are typically open during standard business hours, Monday through Friday.

Setting up automatic payments

If you want to avoid paying your bill each month, you can set up automatic payments through the Department of Public Works website. You'll link your bank account, choose the payment amount and date, and the payment will be deducted automatically each billing cycle. This is useful if you want to may support you never miss a due date.

You can change or cancel automatic payments at any time through your account on the website. If you set up autopay, you'll still receive your monthly bill so you can verify the charges are correct.

What happens if you miss a payment

If your payment is not received by the due date shown on your bill, a late fee will be added to your account. The amount of the late fee varies but is typically a percentage of your bill. You'll receive a notice in the mail if your account is past due.

If your bill remains unpaid for an extended period, the Department of Public Works may disconnect your water service after providing written notice. The notice will give you a timeframe to pay or arrange a payment plan. If you cannot pay your full bill, contact the department to discuss options — they may offer a payment arrangement or direct you to information programs.
