Thunder Bay, Ontario, Canada
Elements of complexity
- Impermeability achieved through the use of a geomembrane.
- Use of a backfilled HDPE alveolar structure to protect the geomembrane from ice and other elements.
- Design needed to be economical and durable, as well as safe.
This project consisted of preparing drawings and specifications for a rockfill dam with a height of 3.5 m and an emergency overflow weir used in the retention of pumped water coming from an old existing mine near the village of Geralton, 2 hours north-east of Thunder Bay. Le project also includes the design of a second rockfill closing-dyke and three energy-dissipating berms.
Hydrosys was hired for the conceptual and detailed engineering as well as all the related studies.
