Manholes – Case Study 3

Description

Clark County has literally hundreds of structures with severe deterioration in locations with extremely high traffic congestion. Sewer flow disruption and prolonged traffic flow disruption could pose a serious problem considering the pedestrian and automobiles traffic congestion and the fact that much of the City businesses are open and running all night long.

Solution

Poly-Triplex installations were coordinated to occur at varying times of the day and night to minimize traffic disruption. In most cases, the Poly-Triplex installers were able to bridge the invert channel allowing the sewage to continue to flow. Most installations were completed in approximately 4 hours.

Benefit

The Poly-Triplex Liner System has effectively solved the problem of infiltration and deterioration in these structures. This trenchless technology saved the county hundreds of thousands of dollars over dig and replace.
