Description
The Rosehill Reservoir is an integral part of Toronto’s water system. Completed in 1874, it holds 270 million litres (71 million gallons) of drinking water and serves 675,000 people across downtown and midtown Toronto. Clean drinking water from the Toronto Island and the R. C. Harris Water Treatment Plants is pumped here and stored in two large underground tanks for distribution. The reservoir was built when the City was constructing a piped water system capable of delivering clean drinking water and eradicating diseases like cholera, diphtheria, and typhoid. Toronto suffered numerous epidemics in the 19th and early 20th centuries as the growing city struggled to provide proper sanitation. Thousands died. The Rosehill Reservoir was originally open to the air and set among landscaped grounds known as Reservoir Park. The reservoir was enlarged and covered in 1966 and extensively renovated starting in 2018; the storage tanks, valve house, and access house were restored, and the mechanical and electrical systems upgraded. The Rosehill Reservoir is the oldest and remains the largest of the 10 ground-level water storage facilities in Toronto’s water system.
