(Created page with "<div style= "text-align:center;">''Message: It is important to understand the condition of the existing pipe before considering sliplining as a viable option.''</div> ----</br> In this Alaska dam, the principal outlet conduit was in need of rehabilitation. The pipe was a good candidate for sliplining and the condition of the pipe allowed for a successful rehabilitation. However, the dam also had an auxiliary overflow conduit that was in need of rehabilitation. As shown...")

The existing conduit consisted of a 24” diameter Riveted Steel Pipe conduit with Corrugated Metal Pipe extension installed when the dam was enlarged. The proposed rehab design was to slipline a 20" OD SDR 15.5 HDPE pipe and grout the annular space...")

The first question the designer needs to ask is whether the conduit should be replaced or is a good candidate for rehabilitation. Conduit replacement is likely the approach providing the greatest reliability, but that approach will most likely require draining of the reservoir and be the highest cost option. In some cases, rehabilitation provides a reasonable alternative. Rehabilitation Replacement Abandonment '''Ad...")

Many conduits may initially look decent, but further investigation shows that the pipe is in need of repair. Missing coatings, corrosion at joints, poor gate condition, and missing corrosion protection are "red flags", and indicate the need for careful intervention. *Pipe Deterioration *Seepage and Piping *Operation *E...")
