Anyone who watched CTV’s W5 investigation into asbestos-cement water pipes probably went straight to the show’s website after the episode had finished to find out how many of those pipes are in Kelowna’s water system. CTV surveyed 100 Canadian municipalities to find out who has asbestos-cement pipes in their system. W5 came up with 195 kilometres of asbestos-cement pipes, or 32 per cent, in the Kelowna water system.
