PROJECT HIGHLIGHTS | 2024-2025

Sachs Harbour, NWT, one of the northernmost communities in Canada at 71° 59’N, required a new portable water treatment plant (PWTP) capable of treating the surface water source, which had degraded due to climate change. BI Pure Water, headquartered in Surrey, was contracted by the community and territorial government to design, manufacture, and install a modular PWTP. Applying advanced technology clarification, ultrafiltration, followed by chlorination and SACHS HARBOUR WATER TREATMENT PLANT

truck filling, the PWTP is designed to meet the latest Guidelines for Canadian Drinking Water Quality . The custom CSA A660 and A277 certified modular building, designed to endure the harsh high Arctic conditions, is equipped with a furnace and back up generator within an RSI 8.6 insulated envelope. It is elevated on beams to protect the surrounding permafrost. The community is only accessible by air and is served by a single annual barge service from Tuktoyaktuk.

FOOTHILLS TRAIL WHITE RIVER BRIDGE Foothills Trail White River Bridge in Buckley, Wash., U.S., is an efficient structural solution with a filigree appearance that provides users with open views over the White River. The triple-arch bridge is supported on seismically upgraded, century old wall piers using base isolation bearings. The bridge provides pedestrians and cyclists access between local communities, amenities, and schools. Environmental stewardship is an essential aspect of this project, as 60,000 migrating salmon travel up the river daily during spawning season. The openness of the structure reduces shading effects on the aquatic habitat below. Weathering and stainless steel were selected to avoid deleterious materials over the water and to ensure longevity. User experience and aesthetics were a focus of design, with equal emphasis on economy, efficiency, and constructability. Lookouts added to the central pier allow users to take in views of the river and landscape. Company: V+M Structural Design, Inc.
