High bill help

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 cluePossible reasonFirst action
Bill rises after April or in summerOutdoor water use, landscape watering, gardens or irrigation.Review outdoor water habits and check whether excess use credit may apply.
Estimated billMeter 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 usageToilet 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 leakWater was lost before repair was completed.Use the official leak adjustment request and attach plumber invoice or parts receipt.
Cannot pay all at onceBill amount may be unaffordable due to high usage or other hardship.Contact Customer Service at 410-222-1144 before the bill becomes more urgent.
💧
Simple leak test: Turn off all water inside and outside the home, then check if the meter still moves. Also check toilets with food coloring, irrigation zones, hose bibs, water heater overflow and damp areas in the yard.
