Threshold

from DA: Threshold starts off with a very unique style of outfall that I don't believe exists anywhere else in the GTA, however I could be wrong. Past that, it continues for a short stretch as a 2000mm RCB, before changing to 3000mm RCP. You then reach a junction room, the first of many as the drain splits up underneath Eglinton and the Mississauga Transitway, all the way to Orbiter drive. The drain consists of at least 2km of pipes, ranging from 3000mm to 1800mm in height, and no doubt some smaller ones as well.
