Rehabilitation Honorable Mention
October 1, 2008
Rehabilitation Honorable Mention: City of Plano, Texas, North Trunk Sewer Main
Insituform Technologies Inc. was awarded the $1 million emergency project. The work began on the grounds of a senior citizen residential complex and Insituform had to coordinate its efforts with the complex’s management. The line then crossed a defense contractor for information technology services that had tight security demands. Adding to the challenge was the requirement for a bypass system designed for a maximum flow of 16.1 mgd. A long stretch of the pipe cut through an unusually severe elevation change for North Texas that could have presented serious access and design challenges as the line went up to 40 ft below ground level in some sections; access to that section was gained via a manhole installed for a toll road sewer crossing.

This project represents one of the most significant uses of the static pipe bursting method with new replacement VCP jacking pipe and demonstrated an exemplary level of cooperation between equipment manufacturer, product pipe manufacturer, contractor, engineering firm and municipality. This project will become the basis for future use of VCP pipe in a static pipe bursting application, project officials say.
