Full Description

The E.L. Smith Water Treatment Plant (WTP) isowned and operated by EPCOR Water ServicesInc. EPCOR supplies drinking water to over onemillion people in the Edmonton Capital Region.Upgrades to the facility are designed to meet thegrowth in the region and ensure a secure highquality supply of water. At the project start, the plant firm capacity was 180ML/d. The initial plant upgrade would be toincrease firm plant capacity to 400 ML/d in order tomeet the projected demand for the next 15 years.However, the new intake would be sized for a netraw water flow of 800 ML/d to provide for futureneeds. The original intake makes no provision for fish caught onthe screens being safely returned to the river. Since the initial building of the E.L. Smith WTP in1976 additional regulations have been implementedto ensure increased protection for aquatic life,wildlife, land and the environment. The presentation lists the regulations. Further clarification of these regulationsnecessitated working closely with a number ofregulatory bodies such as the Department ofFisheries and Oceans (DFO), Transport Canada,Alberta Environment (AENV) and AlbertaSustainable Resource Development (ASRD). Thiscooperative effort allowed the project team topropose initial designs, refine them through positivefeedback, to achieve a final design that satisfied theregulatory bodies and the environmental concerns. The presentation outlines design criteria, intake alternatives, selected raw water system schematic, selected intake alternative, selected screening alternative, computational fluid dynamics (CFD) modeling, physical modeling, and construction. Includes figures.
