Unlike the water from our sinks and toilets which goes to a sewage treatment plant through
the Region of Peel's sanitary sewer system, what we put down our catchbasins or storm sewers
runs directly into a creek or river, then into Lake Ontario. The City's storm sewer system is
monitored and maintained by the Transportation and Works Department. It's important that we do
all we can to keep our catchbasins, watercourses and Lake Ontario clean. After all, we receive
our drinking water from Lake Ontario through a water purification plant.
