Proposal details
This ECA application is for the spill containment systems and stormwater management for two new Hydro Ottawa transformers and associated site redevelopment.
The flow from each oil spill containment will be conveyed to a proposed oil water separator via 250 millimetre diameter pipes.
The effluent from the oil water separator will be discharged to a perimeter ditch along the south property line of the development, which eventually outlets to the existing 600 millimetre diameter municipal storm sewers in Mer Bleue Road via the Mer Bleue roadside ditch.
An additional perimeter ditch is proposed at the north property line. Both ditches have been designed to incorporate additional surface ponding storage to permit retention of received runoff and control release to the Mer Bleue outlet to pre-development levels.
