This junction chamber is where the Morningside and Malvern storm trunks meet before running down into the Morningside Creek ravine.

Wimpey Morningside

Morningside and Malvern Storm Trunk Sewers

Water/Sewershed:
Tributary to Morningside Creek
Rouge River Watershed

Construction Details:
Reasonably large diameter RCPs installed in 1960s to drain new Malvern "model community."

Archival Material:

Wimpey Morningside takes its name from the builders' marks on pipe segments throughout the storm conduit -- two conduits actually, "Wimpey Morningside" and "Wimpey Malvern," which come together before running east into the ravine of Morningside Creek.

There's actually some interesting history to this. In the 1950s, the Canadian Mortgage and Housing Corporation expropriated the land that became the Malvern neighbourhood to build a new, 'model' community, the construction of which took much of the late 1960s and early 1970s.1 Wimpey, a huge international construction concern from the UK, would have been contracted to build not only the sewers, but likely the majority of the neighbourhood. The contemporary successor of this company, Taylor Wimpey, still operates in the GTA under the Monarch Homes brand. The photograph at right, dating from 1966, may very well depict the excavation of the Wimpey Morningside drain.

The drain itself is distinguished by several unusual features. Up the Malvern pipe, a small drop is equipped with a trashrack across the top of the drop, an unusual feature since if the drain actually does carry enough debris to make it necessary it would need to be cleaned manually on a regular basis. In the Morningside arm, a large slide chamber is broken up by a set of massive churnblocks, again a feature more normally seen outside an outfall rather than a kilometer inside a drain.
