There are several reasons a pipeline will collapse
- The pipeline is not buried deep enough
This is usually a result of poor installation or rocky terrain Some soils may have a hard layer that has not been penetrated during installation The best way to install pipelines is with either an Excavator or trench Digger
- The pipeline has rock on the pipe
When pipelines are trenched through Rock they must be bedded in sand or clean spoil
- The pipeline is sucked in when a valve is closed
This problem can be eliminated by installing an Air Vacuum release valve This type of valve also removes ai
r from the pipeline when filling it
