This paper focuses on the South Peel Water System, located in the Region of Peel within the Greater Toronto Area (GTA) in the province of Ontario, Canada. Both of the water treatment plants in the South Peel system are conventional treatment plants. The Lakeview WTP, originally constructed in 1951, has a capacity of 560 ML/d (147 MGD). The Lorne Park WTP, originally constructed in 1976 and expanded in 2002, has a capacity of 340 ML/d (90 MGD). Peel's Water and Wastewater Master Plan identifies the requirements for additional capacity to service increased water demands in the Region. The expansion of the Lakeview WTP was identified in the Master Plan as a requirement to accommodate future population growth in Peel. Along with the expansion of the Lakeview WTP, upgrades to the existing systems at the both plants are necessary. These upgrades are required for the plants to continue to meet and/or exceed current drinking water regulations established by the provincial government. The Ontario Ministry of the Environment (MOE) introduced new Ontario Drinking Water Standards in August 2000 (with some minor modifications in January 2001). Based on a review of federal and provincial legislation, as well as directions set by the U.S. Environmental Protection Agency, the Region of Peel has established water quality parameters for the expansion of the plant that will exceed the requirements established by the provincial government. The need for increased capacity at the Lakeview plant also means that the upgrades to the existing plant will be part of the same construction schedule. Includes table.
