Water Meter

Water meters are an important component of London's Municipal Drinking Water System. Every residential, industrial, commercial, and institutional customer is equipped with a water meter to track consumption.  This ensures that each individual customer is being billed for only the water they consume.

There are more than 110,000 water meters within the city, of which, nearly 100,000 are residential water meters. The Water Operations Division is responsible for replacing, installing, and testing water meters throughout the city.

Water meters are mechanical devices, which require maintenance and/or replacement every so often depending on their size.  Some industrial water meters need to be replaced annually, whereas most residential water meters only need to be replaced about every 12 years.
