The E.L. Smith Water Treatment Plant (WTP) is
owned and operated by EPCOR Water Services
Inc. EPCOR supplies drinking water to over one
million people in the Edmonton Capital Region.
Upgrades to the facility are designed to meet the
growth in the region and ensure a secure high
quality supply of water. At the project start, the plant firm capacity was 180
ML/d. The initial plant upgrade would be to
increase firm plant capacity to 400 ML/d in order to
meet the projected demand for the next 15 years.
However, the new intake would be sized for a net
raw water flow of 800 ML/d to provide for future
needs. The original intake makes no provision for fish caught on
the screens being safely returned to the river. Since the initial building of the E.L. Smith WTP in
1976 additional regulations have been implemented
to ensure increased protection for aquatic life,
wildlife, land and the environment. The presentation lists the regulations. Further clarification of these regulations
necessitated working closely with a number of
regulatory bodies such as the Department of
Fisheries and Oceans (DFO), Transport Canada,
Alberta Environment (AENV) and Alberta
Sustainable Resource Development (ASRD). This
cooperative effort allowed the project team to
propose initial designs, refine them through positive
feedback, to achieve a final design that satisfied the
regulatory 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.
