AACO Water Bill Quick Facts

Choose the Right AACO Utility Action

A county water bill search can mean several different things. The fastest route depends on whether you are paying a normal bill, avoiding late fees, trying to restore service, reporting a sewer backup, or disputing a high usage bill.

How to Pay Your Anne Arundel County Water Bill Online

Anne Arundel County utility bills can be paid through the county online bill and tax payment system. The county says online payments can be made by credit card or eCheck, and payments are processed by Paymentus.

1. Open the official utility billing page.
   Use the county payment link here: Anne Arundel County Utility Billing.
2. Use your current utility account number.
   Do not rely on an old bill if ownership, address, or account status recently changed.
3. Choose payment method and review the convenience fee.
   Online payments are subject to non-refundable convenience fees. eCheck, cards and digital wallet options may be available through Paymentus.
4. Save your confirmation number.
   The county says online payments may show as pending and appear on your account within two business days.
5. Call if the balance or account looks wrong.
   For billing questions, call 410-222-1144 or email custserv@aacounty.org.

AACO Water Bill Payment Options and Fees

Anne Arundel County provides multiple payment routes: online, phone, AutoPay, mail, drop box, walk-in cashier and participating Walmart locations. Choose based on urgency, fee sensitivity and whether you need account support.

AutoPay for Anne Arundel County Utility Bills

AutoPay can help with quarterly bills because it reduces the chance of missing a due date. The county says its online automatic payment option lets you view current total due and set a recurring payment for a fixed amount or the full amount due.

1. Open the county AutoPay option.
   Start from the official Bills and Payments page.
2. Prepare payment details.
   You may need bank routing/account information, name on the bank account, or debit/credit card details.
3. Choose fixed amount or full amount due.
   Full amount due may be useful if you want the current bill paid automatically, but check your bill before the payment date.
4. Watch for confirmation.
   The county says you receive a confirmation of the scheduled payment and another confirmation when the payment comes out.
5. Cancel early if needed.
   The county says cancellations should be done five days before the bill is due.

Late AACO Water Bill, Penalty or Shutoff Risk

Anne Arundel County utility bills should be handled before the net due date. The county states that a 10% late fee is added if payment is not received by the net due date.

1. Check the net due date on the bill.
   Do not wait until the last day if you plan to mail or drop off payment.
2. Confirm the current amount due.
   If the bill is already late, call Customer Service at 410-222-1144 before paying an old amount.
3. Use a faster official payment option.
   For urgent payments, online, phone, or walk-in payment may be safer than mail.
4. Save the confirmation number.
   Keep payment proof until the account shows the payment.
5. Ask if additional action is needed.
   If service is off or close to shutoff, ask what steps are needed to restore or protect service.

What to Do If Water Service Has Been Turned Off

If your water service has already been turned off, do not assume payment alone immediately restores service. The county FAQ says to contact Customer Service during business hours to discuss actions needed for restoration.

• Have your utility account number ready.
• Ask for the full amount required to restore service.
• Ask whether returned payment fees, late fees or other charges apply.
• Use the payment method recommended by Customer Service.
• Save confirmation and write down the name/date/time of the call.

High Anne Arundel County Water Bill: Leak Adjustment, Pool Credit and Summer Usage

A high AACO water/wastewater bill can be caused by indoor leaks, irrigation, pool filling, seasonal outdoor use, estimated readings, or a billing-cycle change. Anne Arundel County lists leak adjustment requests, pool credits and an excess use credit for certain residential summer usage situations.

Collect this before calling Customer Service

• Current bill and previous three quarterly bills if available.
• Utility account number and service address.
• Date you noticed the higher usage.
• Repair receipt, plumber invoice or photos if a leak was fixed.
• Pool fill date, approximate pool size or outdoor water-use notes.
• Payment confirmation if you recently paid the bill.

Water or Sewer Emergency in Anne Arundel County

Billing and emergency service are not the same department. For sewer backups, water main issues, water leaks, disruption of water service or wastewater emergencies, use DPW Emergency Services instead of the billing office.

1. Call emergency services first.
   If there is a sewer backup, water main break, service disruption or active water leak, report it immediately.
2. Protect people and property if safe.
   Keep children and pets away from sewage or standing water. Move valuables only if it is safe.
3. Document visible damage.
   Take photos or videos of backups, flooding, street leaks or property impact.
4. Ask whether the issue is county-side or private-side.
   This helps you understand whether DPW, a plumber or another contractor is needed.
5. Handle billing later.
   Once the emergency is under control, contact Customer Service if the issue may affect your bill.

Mail, Cashier and Walk-In Payment Locations

If you prefer not to pay online, the county gives several non-online choices. These are useful for residents who want to avoid card payments, need cashier support or want to drop off a check or money order.
