Message: Sliplining can extend a dam's design life.


The conduit through this dam was made of corrugated metal. A valve was placed at the downstream end by the owner. The combination of a downstream valve and a corrugated riser pipe led to significant leakage. The pipe was in good condition, but it wasn't made to be pressurized. Sliplining the conduit with HDPE pipe successfully restored the functionality of the dam.
