Where to send your Baltimore County water payment
Baltimore County Department of Public Works handles water billing for most of the county outside Baltimore City. You can pay your bill in three ways: by mail, online, or in person at a payment center.
To pay by mail, send your check or money order to the address printed on your bill — typically the Department of Public Works, P.O. Box 717, Towson, MD 21286. Include your account number on the check. Mail payments take 7 to 10 business days to post, so send them early if your due date is approaching.
Online payment through the county's website (baltimoreountymd.gov) is faster and shows as received immediately. You can set up a one-time payment or enroll in automatic monthly payments from a checking or savings account. The county does not charge a fee for ACH (bank transfer) payments, though credit card payments carry a processing fee of roughly 2 to 3 percent.
In-person payments are accepted at the Department of Public Works office in Towson and at some county service centers. Call 410-887-3680 to confirm hours and locations before you go.
Key Takeaways
- Baltimore County water bills are due on the date printed on your statement, and late fees apply if payment arrives after that date.
- Online ACH payments are free and post immediately, while mailed checks take a week to 10 days and credit card payments charge a processing fee.
- Your bill shows usage in hundred-cubic-foot units (HCF), with a base charge for service plus a per-unit charge for water consumed.
- If you cannot pay your full bill by the due date, contact the Department of Public Works to discuss a payment plan before your account falls behind.
- Automatic enrollment in paperless billing through the county website reduces mail delays and lets you see your bill as soon as it is issued.
Reading your Baltimore County water bill
Your bill shows several key pieces of information. At the top is your account number, service address, and the billing period (usually one month). The due date is clearly marked — payment must arrive by this date to avoid a late fee.
The charges section breaks down what you owe. The base charge is a fixed monthly fee for water service connection. Below that is your consumption charge, shown in units called HCF (hundred cubic feet). One HCF equals 748 gallons. If your bill shows "2.5 HCF," you used 1,870 gallons that month. The per-unit rate varies depending on your water district within the county.
Some bills also show a stormwater fee, which covers the cost of managing rainwater runoff in your area. This is separate from water consumption and appears as a flat monthly charge or a charge based on the size of your property's impervious surface (roof, driveway, patio).
At the bottom of the bill, look for your current balance due and the due date. If you have a credit from a previous overpayment, it will be shown here as a reduction to what you owe.
What to do if you cannot pay on time
If you know you cannot pay by the due date, contact the Department of Public Works before your account becomes delinquent. Call 410-887-3680 and ask about a payment arrangement. The county can sometimes set up a plan that spreads your payment over two or more months, which keeps your account in good standing while you catch up.
Late fees begin accruing once your payment is past due. The longer an account remains unpaid, the higher the total cost becomes. A payment plan stops the accumulation of additional penalties and shows the county you are working to resolve the debt.
If your bill is unusually high and you suspect a leak or meter error, request a meter inspection before you pay. The county can check whether your meter is reading accurately. If a leak is found on your property (not the county's main line), you are responsible for the repair, but the county may adjust your bill for the portion of water lost.
Setting up automatic payments and paperless billing
Automatic monthly payments remove the risk of missing a due date. Log into your account on baltimoreountymd.gov, select your account, and choose the automatic payment option. You can set the payment to deduct from your bank account on a date you choose each month — typically a few days before the due date.
Paperless billing means you receive your bill by email instead of mail. This speeds up delivery and gives you immediate access to your statement. You can still view and download past bills from your online account at any time. Switching to paperless also reduces the chance that a mailed bill gets lost or delayed.
Both automatic payments and paperless billing can be set up or changed through your online account. If you do not have an online account yet, you can create one using your account number and service address.
Understanding usage spikes and seasonal changes
Water usage naturally varies by season. Summer bills are typically higher because of outdoor watering, filling pools, and increased household use during warmer months. Winter bills are usually lower unless you have a leak.
If your bill jumps significantly from one month to the next without an obvious reason (like a new pool or extra household members), a hidden leak is the most common cause. Check for running toilets, dripping faucets, or wet spots in your yard or basement. A small leak can waste hundreds of gallons per month and add $20 to $50 or more to your bill.
If you suspect a leak, request a meter inspection from the Department of Public Works. They can determine whether the water is leaving your home through a leak or being used normally. If the meter is faulty, the county may adjust your bill.
Disputing a charge or requesting an adjustment
If you believe your bill is incorrect, contact the Department of Public Works with your account number and the specific charge you question. Have your bill in front of you and be ready to explain why you think the amount is wrong — for example, "My usage doubled with no change in household size" or "I was away for the entire billing period."
The county will review your account history and meter readings. If they find an error, they will issue a corrected bill. If they find no error but you still disagree, you can request a formal review. This process takes longer but gives you a chance to present your case in writing.
Adjustments for confirmed leaks, meter errors, or billing mistakes are handled on a case-by-case basis. The county typically adjusts bills for leaks on the county's side of the meter (the main line) but not for leaks on your property. However, they may make exceptions if the leak was caused by a defect in the meter itself.
What happens if your account falls behind
If your bill remains unpaid 30 days past the due date, the county may place a lien on your property or refer your account to a collection agency. This damages your credit and makes it harder to sell or refinance your home. Before it reaches that point, contact the Department of Public Works to set up a payment plan.
In some cases, the county can shut off service to a property with a seriously delinquent account. Reconnection requires payment of the full balance plus a reconnection fee. Avoiding this situation is much simpler than dealing with it after the fact.
If you are facing financial hardship, ask the Department of Public Works whether any assistance programs are available in your area. Some counties and nonprofits offer help with utility bills for low-income households, though availability varies.
Frequently Asked Questions
How do I know if my water meter is accurate?
Request a meter inspection from the Department of Public Works by calling 410-887-3680. They will send someone to check whether the meter is reading correctly. If the meter is faulty, they will replace it and may adjust your bill for the period of inaccuracy.
Can I pay my bill with a credit card online?
Yes, the county website accepts credit card payments, but a processing fee of roughly 2 to 3 percent is added to your total. ACH bank transfers are free and post immediately, so that option costs less if you have a checking or savings account.
What if I move and still receive a bill at my old address?
Contact the Department of Public Works with your old account number and new address. They will update your mailing address and can arrange final billing for the old property and setup for the new one. Provide at least two weeks' notice before you move to avoid missed bills.
Is there a discount for seniors or low-income households?
Baltimore County offers a senior property tax credit that may reduce water bills for may have access to homeowners age 65 and older. Contact the Department of Public Works or your local Department of Social Services to learn about income limits and how to apply.
Why is my stormwater fee so high?
Stormwater fees are based on the amount of impervious surface on your property — roof, driveway, patio, and other hard surfaces that prevent water from soaking into the ground. Larger properties with more pavement typically have higher fees. You can request a review of your property's measurement if you believe it is incorrect.
