E.L. Smith Water Treatment Plant Upgrade


Edmonton, Alberta


Computational Fluid Dynamics Analysis


Water Treatment

Associated Engineering was retained to provide conceptual design review, permitting assistance, pre-design, detail design, procurement assistance and engineering services during construction for the upgrade to the E.L. Smith Water Treatment Plant, in order to increase the plant capacity from 240 ML/d to 400 ML/d.

Due to a tight required timeline, Associated Engineering created coordinated design teams working in parallel to develop and deliver the designs. Some of the project components were delivered using traditional design-bid-build, while others were fast-tracked and employed a construction management approach. To accelerate the design, Associated Engineering made extensive use of computational fluid dynamics analyses, and 3-D models of most of the major components. Permitting was complex and required a team to liaise with the various authorities and regulators to ensure that their needs were addressed.
