Louisville, Kentucky (August 10, 2015) – The Plastics Pipe Institute, Inc. (PPI) honored ISCO Industries’ League City 39-inch Waterline Replacement project with the 2015 PPI Project of the Year Award in the Municipal & Industrial Division. This is the third consecutive year ISCO has received this award.
Gulf Coast Water Authority (GCWA) and the City of League City, Texas were faced with the need to renew a critical 39-inch PCCP (prestressed concrete cylinder pipe) water transmission main. The main required replacement of approximately 6,800 feet along Calder Road. The line interconnects the City of Houston and Galveston County, and had been suffering from severe breaks and leaking joints. Maintaining capacity on the line was absolutely imperative. GCWA considered several trenchless methods, eventually choosing Swagelining™ with high-density polyethylene pipe (HDPE) as it provided the best value.
Murphy Pipeline Contractors utilized ISCO Industries for its HDPE pipe due to their knowledge of the product, services, and ability to meet critical time restraints with custom fabrication. ISCO provided 1000 mm OD pipe (39.37’) inside a 39-inch host pipe. The project involved four pulls ranging from 1,250 feet to 2,100 feet in length. The long pull lengths allowed for long-fused sections of HDPE to be installed, eliminating the potential for future leaks.
The project perfectly demonstrates innovative technology that capitalizes on the potential of plastic pipe. No other trenchless method has ever finished a project requiring a fully structural solution at an operating pressure of 125 psi.
Award winners were recognized for exceptional service and significant achievements involving the use of plastic pipe. PPI is the major trade association representing all segments of the plastic pipe industry.
