Public health and safety threats are escalating in Metro Vancouver because an aging sewage handling and treatment system will fail more often as a result of climate change, according to a federal report uncovered by The Vancouver Sun.

The report says heavier rainstorms will frequently overwhelm portions of the region's sewage system and accelerate the spill of raw sewage into Burrard Inlet and the Strait of Georgia.

Burton cited a building study in Ottawa that found "a 25 per cent increase in peak wind gusts caused a 600 per cent increase in building damages.

"Past climate is no longer a good indicator of future climate. . . Infrastructure based solely on past climate won't perform as well as it has in the past."

Wastewater overflows and sewage spills posing "environmental contamination or risks to public health and safety" were rated as the biggest concerns - and are identified as significant threats due to the age and size of the system.
