Why Your Anne Arundel County Water Bill May Be Higher Than Normal
Anne Arundel County bills are based on the amount of water passing through the meter since the last meter reading. Wastewater usage is based on the amount of water delivered through the meter to the home. High usage can come from outdoor watering, leaks, estimated readings, irrigation, toilets, plumbing repairs or seasonal patterns.
| High-bill clue | Possible reason | First action |
|---|---|---|
| Bill rises after April or in summer | Outdoor water use, landscape watering, gardens or irrigation. | Review outdoor water habits and check whether excess use credit may apply. |
| Estimated bill | Meter readers could not access or read the meter because of weather, access or utility work. | Look for “E” after the meter reading date and keep the meter accessible. |
| Sudden unexplained usage | Toilet leak, underground leak, water softener issue, irrigation leak or plumbing failure. | Check fixtures and call 410-222-1144 if the bill seems out of line. |
| High bill after repaired leak | Water was lost before repair was completed. | Use the official leak adjustment request and attach plumber invoice or parts receipt. |
| Cannot pay all at once | Bill amount may be unaffordable due to high usage or other hardship. | Contact Customer Service at 410-222-1144 before the bill becomes more urgent. |
Anne Arundel County Leak Adjustment Request: What to Submit After Repair
The Department of Public Works offers a leak adjustment as a benefit for customers faced with costly plumbing repairs and an associated high utility bill. The official form asks for repair details and documentation.
| Form item | What the County asks for | Practical tip |
|---|---|---|
| Customer and account details | Customer name, account/parcel number, address and telephone number. | Use the same account details shown on the utility bill. |
| Tenant information | If tenant, date of move-in/occupancy is required to process the leak adjustment. | Do not leave tenant move-in information blank if it applies. |
| Leak description | Describe the type and location of the leak. | Be specific: toilet, underground line, water heater, irrigation, crawlspace, etc. |
| Repair date | Date the leak was repaired. | Match the date to your plumber invoice or parts receipt. |
| Proof of repair | Attach plumber invoice. If repaired by customer, provide sales receipt for parts and repair explanation. | Keep copies before mailing or emailing. |
