Quebec City, which is celebrating its 400th anniversary in 2008, decided to
rehabilitate a century old cast iron water main on Dalhousie Street. The 1,000 feet of 8 inch
diameter cast iron pipe on Dalhousie Street is part of a larger project totalling 15,400 feet of water
mains which were rehabilitated in 2007. Dalhousie Street is situated in the old part of Quebec City
where streets are generally narrow and continuously traveled by tourists.
Like many other North American cities, Quebec City has invested greatly in the last few years in
an Asset Management Program with regards to its water, sewer and roads infrastructures. This
Program, although not yet completed, allowed the Engineering Department at the City to target
and mark several streets which badly needed repaving. The ensuing inspection of the water and
sewer infrastructures led to the structural rehabilitation of the water mains under these streets. On many occasions, water mains are also rehabilitated even if the pavement
is in good condition.
This paper presents the specific issues concerning the water mains to be rehabilitated,
especially the Dalhousie Street section, and the decision process used to choose a trenchless
solution. The case study will also describe the technical issues, construction details and the
benefits involved in the structural rehabilitation of these water mains. Includes 4 references, tables, figures.
