Reconstruction of the Île-aux-Tourtes bridge

The Île-aux-Tourtes bridge is a major infrastructure that is used by 87,000 vehicles daily, 10% of which are trucks. Rebuilding this link will better serve the needs of the region’s citizens and improve traffic flow.

The project involves managing water from drilling operations, driving piles (1.5 m in diameter with an average depth of 23 m), air blast cleaning, and concrete casting.

Location Montreal, Canada
Year 2023
Capacity : 100 m³/h


  • Discharging treated water into the Lake of Two Mountains that has strict environmental standards of 30 ppm and a pH between 6.5 and 9.5, as well as managing various metals, hydrocarbons, and contaminants.
  • The water treatment system and operations are carried out on a barge, which provides very limited surface area for a high flow rate of up to 100 m³/h.
  • Very large volumes of water are generated over short treatment periods due to the type of operations.
  • The characteristics of the water extracted vary greatly due to the different components present in the water from each type of operation.
  • The lack of a dedicated, specialized water management operator requires the implementation of a simple, understandable treatment system and accessible technical support.
  • Additives in the water extracted from the site, such as foaming agents, hydrocarbons, and concrete make treatment more challenging.


  • Provide technical support from the Mudwizard teams to optimize the system and ensure its suitability for the various operations and challenges.
  • Install a downstream water filtration and polishing system to keep release of water within acceptable standards for environmental discharge.
  • Ensure there are no site shutdowns resulting from non-compliance of released water after treatment.
  • Cost savings in specialized operational labour.
