How to Pay Your Baltimore City Water Bill Online

The official Baltimore payment portal lets you look up a water bill by 11-digit account number or by service address. When using service address search, enter the address as it appears on the top portion of your bill and use abbreviations like W, N, St or Dr where needed.

  1. Open the official water payment page.
    Use this link: Baltimore City Water account lookup and payment.
  2. Search by account number or service address.
    The account number is 11 digits. If you search by address, type it exactly like the bill shows.
  3. Review the amount before paying.
    Check service address, account number, current balance, past-due amount and due date.
  4. Choose ACH/eCheck or card.
    ACH has no charge. Utility card and other non-ACH payment methods have a city-listed flat fee.
  5. Save confirmation.
    Keep your receipt, confirmation number or screenshot until the payment posts to your account.
Best practice: If your bill is unusually high or the address/account looks wrong, do not rush to pay blindly. Call DPW customer support first at 410-396-5398.

Baltimore Water Bill Payment Fees: ACH vs Card

Baltimore’s payment page lists no charge for electronic checks/ACH. For utility payments made by credit card and other payment methods except ACH, the city lists a flat fee of $2.39.

Baltimore Water Bill Payment Plan Through PromisePay

Baltimore DPW works with PromisePay to offer interest-free payment plans for water bill balances of $50 or more. This can help you keep the account in better standing without trying to pay the full past-due balance at once.

  1. Open the official Baltimore DPW PromisePay page.
    Start here: Baltimore DPW PromisePay.
  2. Enter your account and customer number.
    Use the numbers from your water bill. Also keep your billing ZIP code ready.
  3. Review available plan options.
    Choose a plan you can realistically keep. Missing a plan payment may create new problems.
  4. Save the payment plan terms.
    Keep screenshots or emails showing amount, dates, schedule and support contacts.
  5. Contact PromisePay if you need plan help.
    PromisePay lists support at 410-779-9808, Monday through Friday, 8:30 AM to 4:30 PM ET.
Practical tip: Set a reminder for each PromisePay installment and keep paying any new current bills if required, so the old balance does not keep growing.

Baltimore Water Bill Assistance: Water4All and DPW Help

    Use official Baltimore City Water Bill Assistance or Water4All pages, not random third-party pages.
  5. Keep proof of submission.
    Save application confirmation, emails and staff notes.

High Baltimore Water Bill Checklist Before You Pay or Dispute

A high Baltimore water bill can come from real usage, a running toilet, underground leak, billing catch-up, meter issue, vacancy with hidden usage, or a missed payment. Before filing a review request, collect facts so DPW has something concrete to evaluate.

Check portal usage Use DPW self-service tools to monitor water consumption and compare unusual months.
Running toilet A silent toilet leak can create a very large bill. Use a dye test or listen for refilling.
Vacant property If no one lives there, any recorded use may point to a leak, open fixture or unauthorized usage.
Underground leak Look for wet ground, low pressure, unexplained meter movement or plumber findings.
Payment posting Confirm the last payment posted to the right account before paying twice.
Bill review If you fixed a leak or the bill looks wrong, use the official DPW review/adjustment process.

Collect this before calling DPW

  • Current bill and at least two previous bills.
  • 11-digit water account number and service address.
  • Portal usage screenshots if available.
  • Photos or videos of leaks, meter movement or damaged plumbing.
  • Plumber invoice, repair receipt or parts receipt if a leak was repaired.
  • Notes about occupancy, tenants, vacancy, outdoor use or any unusual activity.

Request a Baltimore Water and Sewer Bill Adjustment

If you identified and fixed a leak, Baltimore DPW provides a Water and Sewer Adjustment Request process. Do not submit a weak request with no proof. The stronger your documentation, the easier it is for customer support to understand what happened.

  1. Fix the cause first.
    Adjustment requests are stronger after the leak or usage problem has been repaired.
  2. Gather repair evidence.
    Keep plumber invoices, receipts, parts proof, photos and dates.
  3. Download or open the official adjustment request.
    Start from DPW’s official water bill adjustment and review pages.
  4. Submit the request with clear explanation.
    Include what happened, when it started, when it was fixed and what proof you have.
  5. Follow up with customer support.
    Call 410-396-5398 if you do not receive a response or need status help.
Do not ignore the due date: Ask DPW what amount must be paid while a review or adjustment request is pending.

Report a Baltimore Water Main Break, Sewer Issue or Water Emergency

Billing support is not the same as emergency reporting. A water main break, sewer backup, major leak, low pressure, hydrant leak or water quality emergency should be reported through Baltimore’s service request/emergency path.

Emergency reporting: Baltimore City residents can dial 311. If calling from outside Baltimore City, use 443-263-2220.
  1. Report the emergency first.
    Do not wait for normal billing customer service if there is sewage, a water main break or public safety issue.
  2. Give the exact location.
    Include street address, cross street, alley, landmark, hydrant location or where water is visible.
  3. Stay away from unsafe areas.
    Avoid sewage, standing water near electricity, sinkholes, street flooding or broken pavement.
  4. Document safely.
    Take photos or videos only from a safe place.
  5. Handle billing later.
    Once the emergency is reported, follow up with DPW billing if the issue affects your water bill.
