AECOM - Pushing the Envelope: Large Diameter Reinforced CIPP Sewer Rehabilitation - 2019

AECOM Canada Ltd.

Like many cities, Winnipeg uses a combined sewer system to collect both wastewater and rainwater runoff. To promote cost efficiency in the rehabilitation of two large egg combined sewers, AECOM evaluated and tendered five alternative technologies of which reinforced Cured-in-Place Pipe (CIPP) was selected. Working within an active recycling facility adjacent to active rail tracks and significant flow bypass requirements were challenges overcome by AECOM and contractor Insituform. The use of CIPP resulted in the installation of the largest CIPP liners ever installed in Winnipeg and some of the largest non-circular and reinforced CIPP liners installed in North America.
