The city of Tempe’s Bell Butte Reservoir upgrade required a “line stop” to insert a 24-in. valve in a 24-in. existing waterline, which necessitated a full lane closure on one of the area’s most used streets. Crews coordinated with the city of Tempe’s seasonal traffic patterns, which are also directly affected by the nearby Arizona State University campus, to successfully complete the connection.

The project consisted of structural steel repairs, coatings, a new drain system and a 24-in. isolation valve for the tank inlet and outlet pipe to an existing 2-million-gallon welded-steel tank. PCL coordinated on traffic control with the Arizona Dept. of Transportation for right-of-way work and generated an archaeological monitoring plan because the site is significant to the local Native American communities.
