About this Project
Supplied and installed eighteen, 21m long, 500mm dia. stainless steel risers into holes drilled through overburden and rock on the bottom of Lake Ontario in 30m of water.
The risers were then grouted into place to permit the tunnelling contractor (Strabag) to complete the outfall by connecting the bottom of the risers with the main tunnel. The tunnel is to be flooded and the diffuser caps removed.
