Archimedes Pump - A solution for fish passage

These pumps, which look like giant screws, rotate in place and act almost like an escalator for water (and fish). They turn at a much lower speed compared to impeller pumps, making them less turbulent to fish, reducing risk of mortality or injury. The screw is positioned tightly in the pump station structure to prevent fish getting caught between the threads of the screw and the walls inside the pump chamber. An Archimedes screw pump often requires a complete rebuild and expansion of the footprint of a pump house which significantly increases the cost to upgrade the infrastructure to make it fish-friendly. This animation was created in collaboration between Watershed Watch Salmon Society and Resilient Waters. It was begun by volunteer animation creators, Nathan Ross and Paul Pajot and finished by Kerel Alaas, as well as many advisors who provided feedback during its development. ​ Nathan Ross is a landscape architect who was studying at UBC School of Architecture and Landscape Architecture's Coastal Adaptation Lab who helped to kick off the original design. Paul Pajot (@paul_pajot) is a visual communication designer and founder of @coucou_design, a design studio based in London, England and helps organizations bring ideas to life from space to screens. Kerel Alaas is a Vancouver based animator and ECUAD graduate who grew up among turkic nomads in Siberia. Alaas' role was funded through the Canada Summer Jobs Program (via Watershed Watch Salmon Society).
