High bill and leak adjustment

Leak Adjustment Requests for High Anne Arundel County Utility Bills

Anne Arundel County explains that unusually high utility bills caused by plumbing leaks on the owner’s side of the meter are the property owner’s responsibility. However, the Department of Public Works offers a leak adjustment as a benefit for customers facing costly plumbing repairs and the associated high bill.

High-bill situationLikely next stepHelpful documents
Confirmed private plumbing leakRepair the leak first, then review leak adjustment request requirements.Plumber invoice, parts receipt, repair date, photos and written repair explanation.

Leak-check tip: Turn off all water inside and outside the home, then check if the meter still moves. Also test toilets with food coloring, inspect hose bibs, irrigation valves, water heater area and damp ground near the service line.

Pool credit

Pool Credits for Anne Arundel County Sewer Charges

If your water usage increased because you filled a swimming pool or hot tub, a leak adjustment may not be the right route. Anne Arundel County says customers can be considered for a reduction of sewer charges on their utility account for water used to fill a swimming pool or hot tub.

When pool credit may help

Use the pool credit resource when the water went into a pool or hot tub and did not enter the sewer system.

What to prepare

Keep your account number, pool or hot tub fill date, approximate gallons, pool size and any required official verification form details.

🏊
Pool-fill tip: Submit the correct pool credit form instead of a general complaint. It helps the County review sewer-charge reduction eligibility more directly.
