Baltimore Water Bill Account Lookup by Service Address

Lookup issue |
Likely reason |
What to try |
|---|---|---|

High Baltimore Water Bill or Billing Error Checklist
A high Baltimore water bill can come from real water use, a leak, sewer charges, billing-cycle changes, payment plan status, an estimated/adjusted bill, a misapplied payment or a service address/account issue. Check the basics before disputing the bill.
Have this ready before contacting DPW
- Current bill and previous bill.
- Account number and service address exactly as shown on the bill.
- Payment confirmation if you recently paid.
- Any PromisePay plan details or Water4All application details.

Water Main Break, Water Emergency or Sewer Issue in Baltimore
A water main break or sewer backup is not a billing question. Baltimore City residents should report water main breaks and other water emergencies through 311 by phone, mobile app or online. Baltimore County customers are directed to call 410-396-5352 for water emergency assistance.
-
Report the emergency first.
Do not try to solve a main break, street flooding or sewer backup through the payment portal. -
Give an exact location.
Share address, cross street, closest landmark, alley, sidewalk or visible water/sewer issue location. -
Stay safe.
Keep children, pets and vehicles away from sewage, flooded streets, sinkholes or fast-moving water. -
Document only from a safe distance.
Photos and videos can help your records, but safety comes first. -
Follow up on billing later.
If the emergency affects your bill or property, contact DPW billing/customer support after the emergency has been reported.
