2019 Pressure District 7 Water Supply Redundancy Study | City of Markham, ON, Canada
The Regional Municipality of York (York Region, or Region) supplies water to nine area municipalities, including the City of Markham (Markham)’s and the City of Richmond Hill (RH)’s water systems. In turn, Markham and RH deliver water to individual consumers. Markham’s PD7 water system is supplied by the Region’s system via a single transmission main from Elgin Mills Road East and Highway 404, from hereon referred to as the Elgin Mills watermain. As there is no redundancy to the area, the supply should not be interrupted. Owing to a lack of redundancy and future anticipated growth around 19 th Avenue and Highway 404, Markham has proposed a short-term solution to loop a 300 mm watermain with RH’s 300 mm watermain across Highway 404 close to Mobius Drive, from hereon referred to as the Mobius Drive watermain. This short-term solution would be in place until a long-term solution is developed, funded, and constructed by the Region. This study is to undertake a hydraulic analysis study
