Mokulmne Aqueduct Seismic Upgrade

Over 420 tons of hot-dip galvanized steel was used in the tight schedule construction of the aqueduct. Located in an environment of high humidity and rainfall, the hot-dip galvanized structural steel and fasteners were used in the structural supports for the 10.5 miles of pipeline. The structural supports, specifically designed to reduce the seismic load on the aqueduct, won a structural engineering design award for innovativeness. The hot-dip galvanized supports replaced supports that corroded and ultimately lead to the redesign. To avoid the extremely high shutdown costs associated with repairs, hot-dip galvanizing was the logical choice for both economics and long-term performance.
