The Scarborough Pumping Station Rehabilitation Project is a seven-phased, fast-paced rehabilitation project including renovation to the existing Pumping Station, originally constructed in 1910. Originally an intake and treatment plant, the pumping station was repurposed decades ago to store and distribute clean drinking water supplied by the R.C. Harris Water Treatment plant approx. 4 kilometers west on the shore of Lake Ontario. The Scarborough Pumping Station currently supplies clean drinking water to a large portion of Scarborough as well as portions of Markham, ON.
The project includes demolition and partial repurposing of an existing 21,000 cubic meter underground concrete potable water storage reservoir, construction of a site cast, prestressed wire wound concrete 5 million liter surge tank, conversion of a wet well to a new dry pipe gallery, and a new connection to an existing 1050mm city watermain.
The project also includes architectural upgrades to the existing administration building and pressure districts, including minor aesthetic treatments, window and door replacements, roofing replacements, bridge/gantry crane replacements as well as a mobile catwalk addition to one of the existing 7T bridge cranes. What was originally the plants intake pipeline was previously converted to a drain to Lake Ontario, and upon completion the drain line will be rehabilitated with a new line, headwall and rip-rap spill pad at the shore of Lake Ontario. Upon completion, a large portion of what was originally underground reservoir will be backfilled and returned to green space, controlled by the Toronto Region Conservation Authority.
