An undistinguished RCP draining the area north/northwest of the old Main Treatment Plant, this pipe floods out towards the lake and shrinks away to nothing north of Dundas Street. Strangely though, a vertical connection was added between this storm sewer and the western arm of the East Toronto and Midway Overflow Sewer. My colleague was able to rappel from the Midway sewer, through this connecting shaft, to investigate the underlying storm sewer, but unfortunately he didn't find anything to make that effort worthwhile. The storm sewer enters the lake on the west side of Ashbridges Bay.
