Steel Casing Pipeline
The water transmission line crosses several street right-of-ways, such as Mesa Street and Resler Drive. In some cases when the right-of-way is a highly transited thoroughfare, special protection for the carrier pipe is needed. To provide extra protection against loading from the high traffic from Mesa Street, and to ensure double containment of the liquid flowing in the carrier pipe, a special casing is installed around the pipe. If the pipe were to break or leak, this casing would direct the liquid a safe distance away from the main street. Also, to protect the carrier pipe from corrosion and electrically isolate the carrier pipe from the casing pipe, special spacer/isolators are installed.
