Aegion subsidiary Insituform has released a video featuring the rehabilitation of a potable water main in Spain.
Working with SORIGUÉ, Insituform’s Spanish branch rehabilitated a 1,250 mm pipeline with a history of breaking down and compromising the drinking water supply to more than 500,000 people in the province of Barcelona.
The rehabilitation couldn’t be completed using traditional trenching as the area is both densely populated and contains high tourist traffic.
For the operation, a 670 m InsituMain® cured-in-place pipe (CIPP) resin impregnated liner, composed of layers of polyester fibre and two layers of fibreglass, was inserted.
The installation used an inversion technique, followed by curing using heat.
