The water meter was in the basement behind the boiler. A brass disc with a dial and a glass face and a row of numbers that turned so slowly you could not see them move. The water meter counted every drop. Every bath. Every dish. Every flush. The water meter was the most patient accountant in the building.

The meter reader came once a month. He had a flashlight and a clipboard and he wrote the numbers down with a pencil. He did not ring the bell. He had a key to the basement. He came and went like weather. The meter reader knew more about your habits than your doctor. He knew when you were home. He knew when you were on vacation. The meter told him everything and he told nobody. The meter reader was the first data analyst and he worked alone.

My father watched the meter. He said water is not free. He said every drip costs money. He fixed the toilet flapper himself because a running toilet was a meter spinning and a meter spinning was money going into the pipe. The faucet dripped and he changed the washer. Twenty cents for a rubber disc that saved ten dollars a month. The economics of attention.

The water meter did not judge. Hot water cold water clean water dirty water. The meter counted all of it the same. A glass of drinking water and a load of laundry and a fire hydrant opened on a summer afternoon. The meter measured volume. The meter did not measure purpose. That was the mercy of the machine.

They put in smart meters. The smart meter sends the reading to the office by radio. Nobody comes to the basement. Nobody writes the numbers on a clipboard. The reading is more accurate. The reading is also more distant. The meter reader used to see the puddle under the boiler and mention it to the super. The smart meter reads the water. The meter reader read the building.
