Water Treatment Plant Piping Repairs for city of Atlanta

As most utilities in the country and around the world, the city of Atlanta has aged infrastructure including some of the steel water treatment process piping at their Chattahochee and Hemphill plants. QuakeWrap design included layers of glass and carbon fiber reinforced polymers applied externally on pipes ranging from 12″ to 72″ without disrupting service. The FRP liners were anchored into the floor with a unique design feature. The lining system was designed to take the entire internal pressure (250 psi) with safety factors well over 2.
