Estimated Bill or High Water Usage: What It Usually Means

📅

Estimated bill marker

An estimated bill is indicated by an “E” after the meter reading date.

Estimated bill details
📈

Outdoor use

Outdoor watering and irrigation can quickly create a higher than normal bill, especially in warmer months.

Excess use credit
🔎

Meter access

Keeping the meter accessible helps reduce estimated bills. Weather, inaccessibility or utility work can prevent meter reads.

Meter read info
Excess use credit: Anne Arundel County applies an excess use credit for residential users in the first full billing quarter after April 30 when qualifying usage exceeds 110% of the previous three-quarter average. This is a wastewater-charge reduction, not a full water-bill wipeout.

Leak Adjustment: What to Do When a Plumbing Leak Causes a High Bill

1

Find and repair the leak

Leaks on the property owner’s side of the meter are the owner’s responsibility. Fix the leak before requesting adjustment.
