If your bill has the word ESTIMATED, every bill you're paying is an estimate of the water you used. It means the Village isn't getting an ACTUAL reading. So when an actual reading is obtained, the water used between the last actual reading and the current actual reading is the actual amount of water used & billed - it's no longer an estimate. There is NO problem with the meter. The problem is with the electronic device sending the readings to the Village. The meter continues to accurately record the actual usage even when the electronic device fails. Also, as water meters age they become less accurate. Meaning they will under-count the amount of water used. The meter will not register usage greater than the amount actually used. So when a new meter is installed you may see an increase in usage, resulting in a larger bill.
