City of Vaudreuil-Dorion, Québec

November 2008 & July 2010

Project Overview

Scope (2008):

1.4km 150mm and 250mm diameter cement lined ductile iron water mains

Scope (2010):

1.1km 150mm, 200mm and 250mm diameter cast and ductile iron water mains

Issues & Objectives:
  • + 40 year old water mains installed in a corrosive soil
  • Many leaks and breaks over the last few years
  • Restore structural integrity
Work Method:
  • Cleaning and drying
  • Projections of NSF61-5 fast set polymeric resin
  • Thickness designed according to ASTM-F1216 Standard
  • Pre and post video inspections
  • When needed, drill-open service lines from inside main

Project Benefits

  • Water main structural reinforcement
  • Prevent leakage and breaks
  • Flow / pressure increase
  • Add several decades of service life
  • Deposits and sediments will not attach to the liner
  • Reduced flushing and maintenance activities
  • Service lines connection are well sealed
  • Eliminate internal corrosion and prevent build-up

Environmental Benefits

  • Minimal amount of excavations
  • Small access pits vs. open trenches
  • Reduced dust and other inconvenience to customers and no traffic disruptions
  • Safe access to surrounding homes and business
  • Use of existing infrastructure as the host pipe
  • No disturbances to surrounding infrastructure
  • Reduced noise, use of heavy equipment and accident risks
  • Low CO2 emissions
