Historically canals have carried water for great distances overland. Water tightness, flow rates, aesthetics and functionality can all be improved with CSP liners. 

A major challenge that MTQ designers faced was maintaining sufficient end area in the new liner to carry the mountain runoff. Relining became the only solution.

Older sewers often need repair or replacing. CSP is used for a number of reline applications for sewer replacement. This will help extend the service life of the original sewer line with expense of replacement.
