With it’s small RCB outfall and much larger main RCP, Trillium is a typical, almost featureless West Etobicoke drain. Even though the Trillium drain has a few smaller side pipes and deep manhole shafts, they don’t break up the monotony of wandering down the 2400mm RCP. One day the Angels of the Underground will be back for another, further tour.
