One of the cities major water filtration plants is located in West Hill at the end of Manse Road. The Frank J. Horgan Filtration Plant sits well back from the road on well manicured lawns, providing 376 million litres of the cleanest water in North America. The Frank J. Horgan Filtration Plant is Toronto's newest water treatment facility. It was constructed from 1974 to 1979 at a cost of approximately $57 million on property acquired by the former Metro Toronto from the former City of Scarborough.
The plant, originally called the Easterly Plant, was named for Mr. Frank J. Horgan, Commissioner of Works for the former Metropolitan Toronto from 1980 to 1989.
To meet Toronto and Region of York's growing demands, a major expansion of the plant by 340 ML/d was completed in 2001. Frank J. Horgan Filtration Plant takes raw water from Lake Ontario and converts it into safe, potable water for final pumping into the system. This is a direct filtration plant, that is water proceeds to the filters directly from the flocculators, eliminating the settling process.
