A water meter is a device that measures how much water you use. It is similar to your gas or electricity meter. Your supplier uses readings from the meter to calculate how much to charge you for your water and sewerage services. If you have a meter, the amount you pay will depend on how much water you have used.

A water main curb valve, also known as a curb stop box is used to control the water supply from the city water main to inside the building.
