Pat Daley from Daley Water Services describes how to inspect a flood-damaged underground mainline in a case study video.

Today we're at a flood-affected area where erosion has eroded along the length of a piece of mainline.

This is the type of thing that needs to be inspected after a flood event.

A lot of mainline is only supported by the dirt around the mainline.

Particularly rubber ring joint pipe where the concrete thrust blocks is what holds all the pipeline together and the dirt over the top.

So if you get areas like this that is exposed, and you start the system without backfilling this erosion, you can very easily pop the pipe out of the ground.
