      • Lee’s Summit: Water Main Pipe Bursting Program

        The city of Lee’s Summit, Mo.’s water department distributes water through a 580-mile-long system of water mains, comprised mainly of cast iron and ductile iron pipe, which in the clay soils has created significant corrosion concerns. As such, the city replaced those mains suffering the greatest repair frequency with Fusible PVC pipe.
