Description

FIELD

The present invention is generally related to enclosures for securing exposed piping and backflow assemblies. More specifically, the present invention is related to backflow assembly enclosures.

BACKGROUND

Backflow preventer security enclosures, or backflow enclosures, are security devices that are used primarily for the prevention of theft and vandalism of a backflow assembly. A backflow assembly, or backflow prevention assembly, is used to protect water supplies from contamination or pollution. In water supply systems, water is normally maintained under pressure to enable water flow. When pressure fails or is reduced, as may happen if a water main bursts, pipes freeze or there is unexpectedly high demand on the water system, contaminated water from the ground, from storage or from other sources may be drawn into the system. In order to prevent such an occurrence, regulations may require there to be an air gap or mechanical backflow prevention assembly between the delivery point of mains water and local storage or use.
These backflow assemblies contain components that include valves, piping, and other equipment. The valves, piping, etc. may be prone to theft since these component parts have value and are left in the open due to the assembly being constructed above ground. Protective enclosures are a very common part in the installation of a backflow assembly. These enclosures are typically constructed at ground level on a concrete slab on which the backflow preventer assembly rests. But when the backflow assembly is located at a height substantially above ground level, it is often impossible to enclose the assembly with a typical protective enclosure.
It would be desirable to have a security enclosure that can be used for backflow assemblies that are located at any height above ground level. It would also be desirable to have a system that can support the weight of the enclosure and secure the enclosure to the ground or some other permanent structure.
