Protecting Whistler’s waterways
Did you know?
At the Vancouver Olympic/Paralympic Centre, rainwater will be collected and reused for toilets and urinals. Meanwhile the athlete villages in Vancouver and Whistler will recover heat from city sewer systems for space and hot water heating.
The three stadiums at Whistler Olympic Park will each hold up to 12,000 people during the Vancouver 2010 Winter Games. That adds up to a lot of toilet flushes. Organizers plan to protect the lush wildlife habitat of Madely Creek — the ultimate destination of all water that goes down the drain. The Olympic Park has an on-site waste water treatment plant that will use leading technology, including ultraviolet (UV) disinfection, to make sure that only pure water returns to the creek. UV disinfection is an environmentally friendly process used at the final stage of sewage treatment. It works by damaging the genetic structure of pathogens, such as bacteria and viruses, so that they can no longer reproduce. After the sewage has gone through a complex course of treatment to remove solids, grit, oils and harmful nutrients, UV lamps deliver a powerful dose of radiation to kill any remaining micro-organisms. UV treatment reduces the need for chemicals such as chlorine, and is very effective against waterborne diseases such as cryptosporidiosis and giardiasis.
