James Jardine Water Purification Plant

Description

The James Jardine Water Purification Plant, located in Chicago, Illinois, is one of the largest water treatment facilities in the world. Serving millions of residents and businesses, this critical infrastructure plays a vital role in providing safe and clean drinking water from Lake Michigan. The plant’s innovative design and advanced technology ensure the efficient filtration and purification of billions of gallons of water annually. As a cornerstone of the region’s water supply system, maintaining the structural and operational integrity of this facility is essential for public health and safety.  

CTLGroup performed a condition assessment of thousands of precast concrete channel slabs that comprised the roof over a large filtration building. Deterioration observed during the visual review included spalled flanges with exposed corroded reinforcement, longitudinal cracking in the flanges, web spalls, and excessive web cracking. Based on the assessment, CTLGroup ultimately determined that replacement of distressed channel slabs was the only practical repair solution.

The City of Chicago commissioned a comprehensive removal and replacement program for the roof of the filtration building. As part of the program, CTLGroup was retained to design a more durable channel slab, which included a high performance concrete mix and enhanced concrete cover over the reinforcing steel. CTLGroup also performed submittal reviews and quality assurance reviews at the precast concrete fabrication plant.
