Where to pay and what payment methods Baltimore accepts
Baltimore City Department of Public Works (DPW) collects water bills and accepts payments through several channels. You can pay online at bwwaterworks.org, by phone at 410-396-5398, by mail, or in person at payment centers around the city.
Online payment through the DPW website is the fastest option — the system processes payments immediately and you get a confirmation number right away. Phone payments work the same way: call the number above and a representative will take your payment information. Both methods accept debit cards, credit cards, and bank account transfers.
If you prefer to mail a check, write it to "Baltimore City DPW" and include your account number on the check itself. Mail payments to the address on your bill; processing takes 7 to 10 business days after DPW receives it. In-person payment centers are located throughout the city — your bill lists the nearest one, or you can call DPW to confirm locations and hours.

Understanding your bill and due date
Baltimore water bills arrive quarterly (every three months) and show your usage, the amount owed, and the due date. The due date is typically 30 days from the bill date. If you pay after the due date, DPW adds a 10 percent penalty to the amount owed plus interest that accrues daily.
Your bill also shows your account number — a unique identifier you will need for any payment or inquiry. Keep this number handy when you call or pay online. The bill lists your water usage in hundred-cubic-foot units (HCF); one HCF equals about 748 gallons. This helps you spot unusual spikes in usage that might signal a leak.
If your bill seems wrong or you do not recognize the amount, contact DPW before paying to ask about it. They can explain the charges and, if there is a genuine error, adjust the bill. Paying a disputed bill does not waive your right to a correction later, but calling first saves time.
What happens if you miss a payment
Missing a water bill payment triggers a series of steps. First, DPW adds the 10 percent late penalty and daily interest to your balance. If the bill remains unpaid 30 days after the due date, DPW sends a written notice warning that service may be shut off.
You have the right to a hearing before disconnection occurs. If you receive a shut-off notice, contact DPW immediately — even a partial payment or a commitment to a payment plan can stop the process. DPW must give you written notice and reasonable time to respond before actually cutting off water service.
Once service is shut off, reconnection requires paying the full overdue balance plus a reconnection fee. This fee varies but is separate from the water charges themselves. If you are struggling to pay, reaching out before the shut-off notice arrives gives you more options and avoids the reconnection cost.
Setting up automatic payments or payment plans
If you want to avoid missing a due date, you can set up automatic payments through bwwaterworks.org. The system allows you to choose the payment date each quarter and will charge your bank account or card automatically on that date. You can change or cancel automatic payments anytime through your online account.
If you cannot pay the full bill amount by the due date, contact DPW at 410-396-5398 before the due date to request a payment plan. DPW can sometimes arrange installment payments spread over several months, which stops late penalties from accruing and prevents shut-off notices. The sooner you call, the more options you have.
Payment plans are not automatic — you must request one and DPW must agree to it. Once a plan is in place, stick to the agreed schedule; missing a payment on the plan can trigger shut-off proceedings just as a missed regular bill does.
Checking your account balance and payment history
You can view your account balance and recent payments anytime at bwwaterworks.org by logging in with your account number and zip code. The site shows your current balance, due date, and a history of payments you have made. This is useful for confirming that a payment you sent by mail has been posted or checking whether an online payment went through.
If you do not have internet access, call DPW at 410-396-5398 and a representative can tell you your balance and payment history over the phone. Keep your account number ready when you call. You can also request a paper bill by mail if you prefer not to manage your account online.
If you notice a payment is missing from your history, contact DPW with the date and amount you paid. If you paid by check, provide the check number. DPW can track down the payment and correct the record if there was a processing delay.
Assistance programs for Baltimore water customers
Baltimore offers a Low-Income Water Assistance Program for households that meet income limits. This program provides a credit toward your water bill each month, reducing the amount you owe. may be able to access is based on household income and size; the income limits change yearly.
To learn whether you may be may be able to access, contact the Baltimore Office of Human Services at 410-396-8000 or visit their website. They can tell you the current income limits and what documents you will need to provide. The program is first-come, first-served, and funds are limited, so applying early in the year increases your chances.
If you are elderly, disabled, or facing a hardship, you may also be may be able to access for emergency assistance through local nonprofits. Call 211 (a free helpline) and explain your situation; they can refer you to organizations in Baltimore that help with utility bills. These programs vary in what they cover and how quickly they process requests.
Avoiding common payment mistakes
One frequent mistake is mailing a check without including your account number. DPW may not know which account to credit, and your payment could sit in a holding account for weeks. Always write your account number on the check itself and on the envelope.
Another mistake is assuming an online payment has gone through without waiting for a confirmation number. If your browser closes or the page does not load fully, the payment may not have processed. Always wait for the confirmation screen and save or write down the confirmation number.
Do not ignore shut-off notices or assume they will go away. Once DPW issues a notice, the clock is ticking. Contacting them immediately — even if you cannot pay the full amount — is your best defense against losing water service. Waiting until the last day leaves no room for processing delays.
