The $900 million Waneta Expansion adds a second powerhouse located immediately downstream of the Waneta Dam on the Pend d’Oreille River. The expansion shares the existing hydraulic head and generates power from water that would otherwise be spilled. Output from the new powerhouse is stepped-up to 230 kV and delivered to BC Hydro’s Selkirk Substation through a new 10 km transmission line. The expansion produces clean, renewable, cost-effective, power for all British Columbians.

As part of this expansion FRPD was contracted by the ASL JV (SNC-Lavalin and AECON) to suction dredge contaminated material, pump this material to area where both the solids and water were treated. FRPD, through the use of turbidity barriers, were able to meet very strict environmental requirements.
