|Materials & Equipment||CSP Aluminized Steel Type ll Spiral Rib Pipe|
|Owner:||North Dakota DOT|

|Application:||Concrete pipe rehabilitation|
|Special Project Elements:||The liner pipe was installed and the annulus was grouted through internal ports. The installation process minimized the time required to rehabilitate this existing pipe.|
Why corrugated steel pipe from TrueNorth Steel?
Existing concrete pipe joints were misaligned and leaking both soil and water. Spiral rib CSP was chosen because of its Manning’s “n” = .012. This allows for maximizing hydraulic capacity.
