Title: Infrastructure Progress Proceeds in Palo Alto, CA

The city of Palo Alto has adopted PE4710 pipe, installed as much as possible by horizontal directional drilling, for ongoing system replacements. The City is on track to replace the entire 214 mile system. The city started to use HDPE pipe because it could be installed by boring instead of the open trench method. A recent study by Jana Laboratories was commissioned by PPI to investigate the effects of disinfection on the lifetime of polyethylene pipes. Based on this methodology, Jana developed case studies and confirmed that 100-plus year life is projected for pipes made from the higher performance PE 4710 materials that are being installed in four utilities. Palo Alto was one of the participants.
