The life-cycle cost of HDPE pipe can differ from other materials because the allowable water leakage is zero, rather than the typical leakage rates of 10 to 20 percent for conventional counterparts. HDPE pipe’s fused joints are self-restraining, thereby eliminating costly thrust restraints or thrust blocks.
