Castle Mountain Hydroelectric Project involved the planning, design, and construction of an independent power project on Castle Creek in the Robson Valley, BC.
DWB was retained by Castle Mountain Hydro in the planning stages of the projects for both engineering and environmental services. This included completing feasibility studies for the project, survey and layout, followed by project management, survey and design of access to the site, hydrotechnical analysis and studies, and the full design of the intake, penstock, powerhouse, and outlet structures. The environmental aspects included environmental plans, monitoring, permitting, reporting, and auditing as the construction progressed.

Castle Creek Hydroelectric Project was a large multi-disciplinary project for DWB, incorporating both the engineering and environmental departments over the course of several years. DWB was integral in the planning portion of the project, as well as in designing the access road, crossings (road and pipeline), and the intake, penstock, powerhouse and outlet channel, and developing and implementing the various environmental aspects and mitigation/compensation for the project.
