HDPE is not conductive so grounding wires cannot be installed. However, HDPE pipe does build up static charges, which need to be discharged during construction operations. A temporary grounding station can be established by wrapping the pipe generously with wet rags that have been soaked in a saline solution. The rags must be in contact with both the pipe and the ground. If a pipe section is to be cut out, temporary grounding stations need to be established on each side of the cut out section.
