Sanexen Environmental Services Inc. was recently awarded a $20 million contract by the City of Montreal, Canada, for the structural rehabilitation of approximately 60,000 ft of distribution water mains.

Under this contract, Aqua-Pipe crews will be responsible for the structural rehabilitation of the water mains located on approximately 75 streets in the residential, commercial and industrial sectors throughout the city center and the 15 of its 19 boroughs.

The City of Montreal’s Water Services Division, which manages more than 2,640 miles of water mains, is responsible for the production and distribution of potable water for 1.6 million people, businesses and industries. In 2005, the City started an Asset Management Program whose master plan proposed massive investments  in its water and wastewater infrastructures for the next 20 years.

Like most cities in North America, the City of Montreal is faced with the costly repairs of water main breaks and consequent water losses. In order to reduce the number of breaks and leaks in their water system, the City started systematically rehabilitating their water mains with structural cured-in-place (CIPP) liners. In the last four years, it has rehabilitated more than 150,000 ft of small diameter distribution water mains with the use of Aqua-Pipe, a structural CIPP liner.  For the years 2008 to 2010, the City saved more than $60 million in direct costs for the structural rehabilitation of approximately 120,000 ft of water mains, compared to replacing the pipes using the open-cut method.
