Anne Arundel County Utility Rates Changed for Fiscal Year 2027

The county’s current rate page lists a water usage rate of $3.98 per 1,000 gallons and a wastewater usage rate of $7.00 per 1,000 gallons, effective July 1, 2026. Most residential utility accounts are billed quarterly, so compare a 2026 bill with the rate period that actually applies to that billing cycle.

Water usage $3.98 per 1,000 gallons.
Wastewater usage $7.00 per 1,000 gallons.
Infrastructure Maintenance Fee 35% of water and wastewater charges.
Account Maintenance Fee $6 per bill for a metered account; $3 for an unmetered account.
Bay Restoration Fee $15 per bill for a residential property.
Final bill $35 for a property transfer or change in tenancy.
New Utility Investment Fee: The current utility-rate page says the UIF begins with the second billing cycle in Fiscal Year 2027. Most quarterly customers will first see it on an October, November or December bill, depending on billing cycle. The fee depends on meter size and whether the account receives water, wastewater or both.

How to Pay an Anne Arundel County Water Bill Online

Start from the county Utility Billing Information page. Use the Pay Online route to the Anne Arundel County self-service billing system rather than a search ad or unrelated third-party bill-pay page.
Locate the correct utility account and bill. Review the customer record and select the water/wastewater bill you intend to pay.
Check the due date and unpaid balance. Confirm that the bill type, account, service address and amount match before continuing to Paymentus.
Select the payment method. Utility credit and debit card payments have a $3.25 convenience fee. eCheck payments have a $0.50 convenience fee.
Review the Paymentus confirmation screen. Check the payment date, amount and non-refundable convenience fee before authorizing the transaction.
Save the receipt and confirmation email. The county says an online payment can remain pending and may take up to two business days to appear on the account.
Payment timing: Do not submit a second payment only because the balance still appears after checkout. Keep the confirmation number and allow the county’s stated posting window unless the account is already at a shutoff deadline.

Why the total is more than gallons times rate

How an Anne Arundel County Utility Bill Is Built

Water and wastewater usage are only part of a typical county utility bill. The exact bill depends on service type, meter size, usage, payment history and account-specific charges.

Water Usage $3.98 per 1,000 gallons under the July 2026 rate.
Wastewater Usage $7.00 per 1,000 gallons when wastewater service applies.
Infrastructure Fee 35% of water and wastewater charges.
Fixed Fees Account maintenance and Bay Restoration fees may apply.
Account-Specific Items UIF, late charges, old balances, credits or other approved charges.
Sewer-only accounts: The county says unmetered wastewater-only residential customers are billed quarterly at a flat amount based on an average of 14,000 gallons for a family of three. Customers who consistently use less may want to ask Customer Relations whether installing a private meter would be cost effective.
New FY2027 bill component

What Is the Anne Arundel County Utility Investment Fee?

The Utility Investment Fee is based on water-meter size and whether the property receives water, wastewater or both. The current rate page says the fee begins with the second billing cycle of Fiscal Year 2027.

Meter size Water UIF Wastewater UIF
Less than 1 inch $5.61 $14.92
At least 1 but less than 1.5 inches $9.37 $24.92
At least 1.5 but less than 2 inches $18.68 $49.68
At least 2 but less than 3 inches $29.90 $79.50
At least 3 but less than 4 inches $59.86 $159.20
At least 4 but less than 6 inches $93.52 $248.72
At least 6 but less than 8 inches $186.92 $497.28
At least 8 but less than 10 inches $299.18 $795.60
10 inches or more $785.40 $2,088.80
Timing note: The dedicated 2026 rate page says most quarterly customers will see the UIF on an October, November or December bill depending on billing cycle. Because another county FAQ displays an inconsistent implementation date, use the rate page and the actual bill for final confirmation.
High-bill diagnosis

Why an Anne Arundel Water Bill Can Suddenly Increase

Estimated meter reading An estimated bill is marked with an E after the meter-reading date. The next actual reading should reconcile the difference.
Seasonal outdoor use Irrigation, landscaping, pool filling and other summer use can increase consumption quickly.
Private-side plumbing leak Running toilets, underground service-line leaks and irrigation leaks can raise both water and wastewater charges.
New 2026 rates or UIF Compare the bill’s service period with the July 1 rate change and check whether the new UIF is present.
Late or returned payment charge A 10% late fee or $25 returned-payment charge can raise the total even when usage did not increase.
Previous unpaid amount Review current charges separately from an old balance or installment-related amount.
Meter reread: The county FAQ says a customer may request a meter reread and verification for $35. If the original reading is found incorrect, the fee is waived.
Credits that reduce eligible wastewater or leak charges

Leak Adjustment, Summer Excess Use Credit and Pool Credit

Leak Adjustment Repair the private-side leak first, keep the plumber invoice or repair proof, and submit the county request. The county describes the adjustment as a courtesy and generally does not approve it more than once every five years.
Summer Excess Use Credit For eligible residential accounts, the county automatically reduces part of the wastewater charge in the first full billing quarter after April 30 when water use exceeds 110% of the prior three-quarter average.
Pool or Spa Credit A customer may request a reduction of sewer charges for water used to fill a pool or hot tub when the water did not enter the sanitary sewer system.
Leak adjustment mailing route: Anne Arundel County Customer Service, P.O. Box 427, Annapolis, MD 21404. The form can also be emailed to custserv@aacounty.org.

Open the official leak adjustment request page and review the official pool credit form.

Moving, sale or tenant change

How to Change the Owner, Tenant or Billing Address

Anne Arundel County uses specific forms for utility billing changes. A profile edit alone is not a substitute when ownership or tenancy changes.

Situation Who submits Action Related charge
New property owner New owner or title company Submit the New Owner Change form A final utility bill for property transfer is $35
New or changed tenant Property owner Submit the Tenant Change form Final bill for change in tenancy is $35
Mailing/name correction Responsible account/property party Use the county billing name/address change process Confirm any account-specific effect with Customer Service
Submission: Completed owner or tenant change forms can be emailed to custserv@aacounty.org or mailed to Anne Arundel County Customer Service, P.O. Box 427, Annapolis, MD 21404.
