Certa-Lok® Large Diameter Pipe Featured In Trenchless Technology Magazine
NAPCO's Certa-Lok® restrained-joint municipal sewer pipe was featured in Trenchless Technology: Large-Diameter Restrained-Joint PVC Pipe Helps Chicago Suburb Get Relief From Sewer Backups - Trenchless Technology, Horizontal Directional Drilling Guide, July 2015.
This article recounts how the city of Elmhurst, Illinois, a suburb of Chicago, used nearly 2,000 feet of 18 inch Certa-Lok® C905 restrained-joint PVC pipe to help divert excess sewage generated by extreme weather from entering and overwhelming the Water Reclamation Facility and causing sewer backups in area homes.
