This project includes removal of interior mortar lining of fifteen locations on the Jordan Aqueduct Reach 1, a 78-inch weld steel, mortar lined and coated pipe, which were identified to have wall loss from a 2020 condition assessment. JVWCD’s consultant will verify wall loss in these locations using nondestructive methods. If wall loss is occurring on the interior of the pipe, an interior patch will be placed and the interior mortar coating will be repaired. If wall loss is measured and not found on the interior of the pipe, the exterior of the pipe will be exposed, corrosion treated, an exterior patch will be placed and the interior and exterior linings will be repaired. Three exterior joints on the Jordan Aqueduct Reach 1 will be exposed and inspected. A section of the Jordan Aqueduct Reach 4 will also be exposed to investigate a current drop if the aqueduct’s cathodic protection current.
