Dear Guillermo, My ...

Dear Guillermo,

My experience with HDP has been to transport Natural Gas. When a leak happens it can be detected by odor, gas detection, pressure loss, marks in the ground or the flow reconciliation is not closing as usual. It those cases a mechanical sleeve (full-circle band clamps) is used as a first measure. Later on, after further analysis, the pipe is replaced. 

For water applications, I think a mechanical repair should suffix. 

In the following site you can find some info: https://plasticpipe.org/pdf/asce-pipelines-2014-hdpe-repair.pdf.
