Where to send your Baltimore County water bill payment

Baltimore County Department of Public Works handles water billing for most of the county outside Baltimore City. You can pay your bill by mail, online, by phone, or in person at their office. The mailing address for checks is Baltimore County Department of Public Works, P.O. Box 717, Towson, MD 21286. Include your account number on the check or money order.

Online payment through the county's website is the fastest way to avoid delays. You'll need your account number and the amount due. Phone payments go through an automated system at 410-887-3800, and you can also pay in person at the DPW office in Towson during business hours. Each method processes at different speeds, so timing matters if your bill is due soon.

Key Takeaways

  • Baltimore County Department of Public Works processes water bills for unincorporated county areas, and you can pay online, by phone, mail, or in person.
  • Online payment through the county website is fastest and shows confirmation immediately, while mailed checks take 7 to 10 business days to post to your account.
  • Your account number appears on your bill and is required for all payment methods except in-person payments at the DPW office.
  • Late fees and service interruption begin after the due date shown on your bill, so confirm your payment posted before that date if you paid by mail.
  • If you live in a municipality within Baltimore County, your water may be billed by that city or town instead, so check your bill for the billing entity name.

Online payment through the Baltimore County website

The county's online payment system lets you pay immediately without leaving home. Go to the Baltimore County Department of Public Works website, select the payment option, and enter your account number and the amount you owe. You can pay with a debit card or bank account. The system shows your payment confirmation right away, and the county records it within one business day.

Online payments avoid the mail delay that can cause late fees if your check arrives after the due date. There is no fee for paying online through the county's official system. If you set up an account, you can also view your billing history and see when payments posted.

Phone payment and automated systems

Call 410-887-3800 to pay by phone using the automated system. You'll need your account number and a debit card or bank account information. The system processes the payment immediately and gives you a confirmation number. Write down this number in case you need to verify the payment later.

Phone payments work during business hours and after hours through the automated line. If you have questions about your bill or account, you may need to call during business hours to speak with someone. Keep your confirmation number until you see the payment posted on your next bill or online.

Mailed checks and payment processing time

If you mail a check, send it to Baltimore County Department of Public Works, P.O. Box 717, Towson, MD 21286. Write your account number on the check. Mailed payments take 7 to 10 business days to reach the office and post to your account, so mail your payment at least two weeks before the due date if you want to avoid late fees.

The county processes checks in the order they arrive, and the postmark date does not protect you from late fees — only the date the payment posts to your account matters. If your bill is due soon and you choose to mail it, you risk a late fee. Online or phone payment is safer if you're close to the due date.

In-person payment at the DPW office

You can pay in person at the Baltimore County Department of Public Works office in Towson. Bring your bill or account number and cash, check, or debit card. Payment posts to your account the same day. The office is located at 401 Bosley Avenue, Towson, MD 21286, and is open during standard business hours Monday through Friday.

In-person payment is useful if you need the payment to post immediately or if you prefer to handle it face-to-face. You can also ask questions about your bill or account while you're there. Parking is available at the office.

What happens if you miss the due date

Late fees begin after the due date shown on your bill. The county adds a penalty to your next bill and may charge interest on the overdue amount. If your bill remains unpaid for 60 days, the county can shut off your water service. Once service is disconnected, you must pay the full amount owed plus a reconnection fee to restore water.

If you cannot pay by the due date, contact the Department of Public Works before the deadline. They may be able to work out a payment plan or discuss your options. Waiting until after service is shut off makes the situation more expensive and harder to resolve.

Municipal water systems within Baltimore County

Some cities and towns within Baltimore County operate their own water systems and bill separately from the county. Towson, Dundalk, and several other municipalities have their own water departments. Check your bill to see which entity is billing you — it will be printed at the top or in the return address.

If your bill is from a municipal water department rather than Baltimore County, contact that city or town directly for payment options. Each municipality has its own payment methods, mailing address, and phone number. Paying the wrong entity delays your payment and can result in late fees.

Frequently Asked Questions

How do I find my account number?

Your account number appears on your water bill, usually near the top or in the billing section. It's a series of numbers specific to your property. If you can't find your bill, call Baltimore County Department of Public Works at 410-887-3800 and provide your address to get your account number.

Can I set up automatic payments for my water bill?

Yes, you can set up automatic payments through the Baltimore County website or by calling 410-887-3800. Automatic payments deduct from your bank account on the due date each month. This prevents late fees and removes the need to remember to pay manually.

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

Online payments usually post within one business day. Check your confirmation number and the amount you entered. If more than one business day has passed and the payment still hasn't posted, call 410-887-3800 with your confirmation number so they can look it up in their system.

Is there a fee for paying my water bill?

There is no fee for paying through the county's official online system, by mail, or in person. Phone payments through the automated system are also free. Third-party payment services may charge fees, so use the county's direct payment methods when possible.

What if I live in a city within Baltimore County — who do I pay?

Check your bill to see which entity is billing you. If it says Baltimore County Department of Public Works, pay them. If it lists a city or town name, contact that municipality's water department. Paying the wrong entity will not credit your account and can result in late fees.
