Coquitlam Mayor Richard Stewart says crews from Fraser Health and the Environment Ministry spent yesterday monitoring Scott Creek after the sewage spilled from the broken pipe Saturday night.
It's not clear how much leaked out, but Stewart says it was a 'significant' amount. The pipe carries about one million litres of sewage per day.
Stewart says his city has a good program to replace aging pipes, but the federal government should be doing more to help.
"This is really a symptom of the challenges we have as a country, cities across Canada have to deal with an enormous, what we call an infrastructure deficit," said Stewart.
"Our infrastructure is aging and we don't really have a coordinated and comprehensive strategy to upgrade the infrastructure that's in the ground."
