How Anne Arundel County Calculates Your Utility Bill
A high bill makes more sense when the customer separates water usage, wastewater usage, fees, service type and payment history.
| Bill part | What it means | What to check | Useful official page |
|---|---|---|---|
| Water charges | Based on the amount of water that passed through the meter since the last meter reading. | Compare quarterly usage to the same season last year. | Billing information |
| Wastewater charges | Usually based on the amount of water delivered through the meter to the home. | Remember that indoor and outdoor water may affect the bill differently through credits or wastewater calculations. | Utility rates |
| Wastewater-only flat rate | Public wastewater-only customers may be billed a flat rate based on 14,000 gallons per quarter. | If your household uses less, ask whether a metered wastewater account could help. | Wastewater-only details |
| Late fee | A 10% late fee is added if payment is not received by the net due date. | Check the due date, not just the billing date. | Late fee info |
| Potential extra charges | The bill can vary based on services provided, usage and payment history. | Look for line items such as UIF, account maintenance, connection, surcharge or penalties. | Rate card |

Inclement weather, inaccessibility or utility work can prevent meter reading.
How estimate is made
The county says estimates are based on the prior year’s bill during the same time period.
How to spot it

Leak Adjustment: What to Do After a Plumbing Leak
A leak adjustment is not automatic and does not erase the entire excess bill. Treat it like a documented request.
| Step | What to do | Why it matters | Official action |
|---|---|---|---|
| Fix the leak | Repair the plumbing problem on the property owner’s side of the meter. | The county says owner-side plumbing leaks are the owner’s responsibility. | Read leak policy |
| Collect proof | Keep plumber invoice, repair receipt, date found, date repaired, and description of the leak. | A repair bill from a licensed plumber may be required for certain adjustment inquiries. | Get request form |
| Submit request | Email the completed request to custserv@aacounty.org or mail it to Customer Service, P.O. Box 427, Annapolis, MD 21404. | Customer Service needs the form and account details to review the request. | Email Customer Service |
| Set expectations | Leak adjustment may reduce but not eliminate excess water consumption charges. | The county says it is primarily a courtesy and may not be approved more than once every five years. | Call 410-222-1144 |
