Maintaining Your Water Meter Box
or Curb Box


If you have an outside water meter box serving your house, it is about 10 inches in diameter with a cast-iron top. In residential areas, it is usually located between the sidewalk and the street, in the sidewalk, or near the edge of the road if there is no curb or sidewalk.


A water meter box serves two functions. It allows CWA to easily access the water meter and provides a master shut-off valve that serves your house without requiring CWA to enter your home.


If you have a curb box on your property, it is about 4 inches in diameter and is also located near the curb. The curb box gives CWA access to the master shut-off valve serving your home. With a curb box, the water meter will be inside your house.


There are several things you can do to provide CWA with easy access to the meter box or the curb box.  Access is particularly important during an emergency when CWA needs to operate the valve located in the box.


Keep items such as trash canisters, potted plants, vehicles, and debris

off the meter box and curb box.

Trim the grass around the meter box and curb box.

Do not plant flowers around the meter box or curb box that may

  hide it from view.

Keep shrubbery and other landscaping from obstructing clear and

  easy access to the meter box and curb box.
