Erie County is home to nearly 1 million people in western New York.The Buffalo-Niagra metropolitan area is the second largest region in the state. In the 1970s, 30” prestressed concrete cylinder pipe (PCCP) manufactured by Interpace was installed near an electric grid system. During this time Interpace PCCP included defective materials and poor practices. After years of leaks and frustration with the Interpace pipe, Erie County Water Authority sought replacement. Corrosive soils, a five-lane highway, and overhead power lines meant multiple considerations from the ground up.
Read this case study and learn why an engineer says Thompson Pipe Group prestressed concrete cylinder pipe was the concrete choice to replace the Interpace pipe. With decades of superior performance, AWWA C301 was the only pipe specified for a project which included stray currents, corrosive soil and multiple trenchless sections.
