Commissioning of the potable water production system

Location: Municipalities of Saint-Bruno, Larouche and Héberville-Station

Roche was hired by three municipalities to build a 7 400 m3/d potable water well, approximately 20 km of transmission main (300 to 400 mm), 1 main chlorination station, 2 secondary chlorination stations and flow measurement and pressure control chambers. The project also involved building a 3 200 m3 epoxy steel reservoir and the demolition of various outdated pieces of equipment. The potable water supply is now provided by a pumping system in the wells that directs the water to a reservoir shared by the three municipalities. From the reservoir, the water is supplied to all of the partners via gravity feed.
