The City of Markham’s water distribution system is supplied through the Region of York transmission network with water derived from the City of Toronto and the Region of Peel. Accordingly, the City does not engage in treatment or disinfection operations as raw source water from Lake Ontario is treated by the supplying utilities prior to reaching the City’s system. Moreover, it is understood that the City of Toronto and Peel Region (as well as York Region, where necessary) typically use chloramination for secondary disinfection as it is less volatile (more stable) than chlorination alone, therefore maintaining a long-lasting disinfectant residual. This is particularly important in distribution systems, such as the York Region-Markham system, which may be subject to high water age from long residence times and potentially low turnover via processing through numerous storage facilities. To protect consumers from microbiological risk, the City monitors a wide range of water quality param

This project is for the City of Vaughan to develop an Integrated Urban Water Master Plan Environmental Assessment Study (MPEA) to assess existing and planned urban water systems and establish a long-term strategy to provide safe, reliable and sustainable services to support revised growth projections, intensification and updates to Provincial, Regional and other City Master Plans. Population forecasts for York Region in the revised Provincial Growth Plan (2017) for the Greater Golden Horseshoe (Growth Plan), estimated residential and employment population is expected to reach 1.79 and 0.9 million respectively by 2041. Residential and employment populations were approximately 1.18 and 0.59 million respectively in 2016. It is anticipated the City of Vaughan will absorb a large proportion of this population increase. Additional to growth forecasts, the updated Growth Plan provides revised policies regarding land development, resource management and protection, and public money investmen
