Hammersley Dyke Fish-Friendly Water Pump Station

Agassiz, British Columbia
This project involved the new construction of a flood mitigation pump station in the Hammersley Dyke on the Fraser River. A massive concrete inlet structure housed two 9-foot (2.7 metre) diameter water turbines to draw freshet water from one side of the dyke and pump it directly into the Fraser River.
Challenges
  • River and stream cofferdams were a challenge to install and maintain during run-off periods.
  • Dike water levels and permits were challenging with many environmental and utilities involved.
Additional Scope Items
  • Installation of reinforcing concrete channels for the new pumps.
  • Pre-engineered foundation and outfall concrete structures.
  • Heavy civil works including dike reconstruction.
  • Large diameter epoxy-coated steel outfall piping.
  • Concrete construction of the site inlet and outlet headwalls.
  • Work involved environmentally-sensitive water management.
