Sorry, Shizean, I was out of town and just saw your question.
There are 12 water reservoirs around Edmonton and they hold millions of litres. Most reservoirs are in neighbhourhoods and the water is pumped out when water demand in the system is greater than the treatment plants can provide. The reservoirs are the back up during high demand periods. They usually fill the reservoirs up at night when water demand is low throughout the city.
All the reservoirs and treatment plants are connected by a distribution system which can feed any part of the city. However, EL Smith in the west end usually supplies west and north Edmonton while Rossdale downtown supplies south and east. If one plant is down for repairs, the other plant can supply enough for the entire city for 1-2 days.
So, long story short, there are two treatment plants but either or both may be supplying your water at any given time no matter where you are in the City. They both use the same "raw" water (the North Saskatchewan River) and use the same processes and additives for disinfection. That's why I feel the water is the same for any location in Edmonton.
