Time & Cost
The historical failure rate of HDPE pipelines has been very low
and is often due to improper installation or design issues, or subsequent third party
damage. In general, repair times and costs vary widely, but for planning purposes may be
roughly estimated to be in the range of 5 to 7½ hours (excluding travel), and $1,000 to
$7,000, per incident, for HDPE distribution systems, depending on the pipe size; see table
below. These times and costs are intended to include excavation and reinstatement.
Representative Repair Times and Costs for HDPE Pipe
It is emphasized that these values are only rough estimates that will vary widely based on individual
applications and circumstances. Furthermore, to the extent that the repair time and cost is reportedly primarily
driven by the pipe size and associated burial/excavation depth, the net overall repair time and cost may be
relatively insensitive to the type of pipe material.
