INNOVATION-May-June-2020

ANDERSON CREEK FISHWAY Previous development had created a three-metre-high concrete fish passage barrier in Anderson Creek, adjacent to the LNG Canada project now under construction in Kitimat, BC. McElhanney’s design created stable water flows through a series of box culvert steps, allowing pink and coho salmon to bypass the barrier and navigate upstream for the first time in 65 years, and in a range of conditions. The project accommodated a smooth transition for fish between the creek and the fishway, while providing protection to previously eroded banks. The fishway will provide access to 3,500 square metres of new spawning habitat. After construction was substantially completed in June 2019, hundreds of salmon were counted upstream of the fishway. It is estimated the newly accessible spawning habitat will accommodate up to 600 mating pairs annually.

ENERGY EFFICIENT MODULAR HOUSING As a part of the Government of BC’s approach to addressing the provincial housing crisis, BC Housing has implemented a rapid response modular housing strategy, which uses modules from Horizon North Logistics of Kamloops. Modular construction is not only a rapid construction technique, it can also provide better quality control, has low on-site impact, and is reusable, reconfigurable and re-locatable. Focal Engineering provided energy modelling for over 30 of these projects to date, helping optimize energy performance while considering comfort and cost. Projects are modelled to higher steps of the BC Energy Step Code and work with unique site-specific considerations. Modeling includes exploring low-cost passive measures to address problems like overheating before costly energy intensive measures are implemented. The overall strategy is intended contract by a large Caribbean housing developer, West Indies Home Contractors Ltd., to design and build a wastewater treatment plant in Montego Bay, Jamaica. With Phase One in operation, and Phase Two and Phase Three in their final stages, the plant serves a development with an ultimate capacity of 2,200 residential one, two, and three- bedroom units. The plant utilizes ECOfluid’s stainless steel Upflow Sludge Blanket Filtration (USBF) clarifiers, to ensure a long effective lifecycle. ECOfluid’s scope of work included all mechanical work, and electrical and controls components supply and installation. The plant is the third wastewater treatment plant designed and supplied by ECOfluid to clients in Jamaica. ECOfluid: Brian Chan, P. Eng., Zhidong Li, Karel Galland, P.Eng. FRIENDSHIP HOUSING DEVELOPMENT WASTEWATER TREATMENT PLANT ECOfluid Systems Inc., a Vancouver company, was awarded a

to deliver a safe, comfortable, environmentally friendly and cost-effective solution to the housing crisis. Participants: Focal Engineering: Riley Beise, P.Eng. BC Housing, Horizon North Logistics, and JRS Engineering.
