details are page 25
Highlights:
Only major city in the world with complete tertiary treatment of ALL waste water releases including full UV treatment of ALL waste water.
100 % complete seperation of sewage and storm system infrastructures.
Over 50% primary treatment on storm sewage system; Edmonton is the only other Canadian city to provide treatment on storm system outflows.
Calgary's newest treatment plant - Pine Creek - is considered the most advanced in the world with "double" tertiary treatment involving both UV and O3. (cost is pushing over 500 Million)
According to Ecojustice, Calgary and Edmonton (and Whislter) are the only cities in Canada that return waste water to the environment cleaner than when it was extracted.
BTW, Regina does has a good waste water treatment system, though it doesn't address storm runoff, and as of 2008, it's UV system has been running at less than 100% and it doesn't provide for O3 treatment.
