High water consumption can be a function of several factors. The period between successive water meter reads can vary from 27 to 34 days. An estimate of monthly consumption and the meter read on the following month will adjust for any inaccuracies in the prior month's estimate.
Occasionally there may be a leak, either in the ground between the meter and the building or inside the building, such as a malfunctioning bathroom fixture. Finally, on rare occasions, the meter may be defective, although in most instances defective meters report low consumption.
The customer has the right to request testing of the meter but must pay a fee if the meter proves to be no more than 2% higher than what it should have been reporting.
