New design guide for HDPE pipe in seismic-prone areas availableThe latest technical document from the Municipal Advisory Board details the required wall thickness for a high-density polyethylene water main that is subject to the fault crossing seismic hazard. The 38-page MAB-10 2025, Design of HDPE Water Mains for Crossing Seismic Hazard includes formulas, calculations and charts plus information about pipeline response to strike-slip events. It partners with the previously published MAB-9, Design of HDPE Water Mains for the Lateral Spread Seismic Hazard. Both are available for free on the group’s website at plasticpipe.org/mabpubs.
