Toronto Water is the municipal division of the City of Toronto under Infrastructure and Development Services responsible for the water supply network, and stormwater and wastewater management in Toronto, Ontario, Canada, as well as parts of Peel and York Regions. History Early days Water treatment was originally established in order to provide safe drinking water. In the 19th century, the water off the city's shores was severely polluted by the dumping of waste from residences and businesses. Before 1842, Toronto's water supply was manually pumped from Lake Ontario, streams and wells. Water carters would take the water and distribute it to customers across the city. Private water supply From 1843 to 1873, water was privately provided by Furniss Works or Toronto Water Works, a subsidiary of Toronto Gas Light and Water Company, which was owned by Montreal businessman Albert Furniss.

Flocculation
In colloidal chemistry, flocculation is a process by which colloidal particles come out of Suspension (chemistry), suspension to sediment in the form of floc or flake, either spontaneously or due to the addition of a clarifying agent. The action differs from Precipitation (chemistry), precipitation in that, prior to flocculation, colloids are merely suspended, under the form of a stable dispersion (where the internal phase (solid) is dispersed throughout the external phase (fluid) through mechanical agitation) and are not truly dissolved in Solution (chemistry), solution. Coagulation (water treatment), Coagulation and flocculation are important processes in fermentation and water treatment with coagulation aimed to destabilize and aggregate particles through chemical interactions between the coagulant and colloids, and flocculation to sediment the destabilized particles by causing their aggregation into floc.

Part V of the ''Act'' allows for the designation of heritage conservation districts. Amendments to the legislation Until 2005, a designation of a property under the ''Act'' allowed a municipality to delay, but not ultimately prevent, the demolition of a heritage property.

Old Toronto
Old Toronto is the part of Toronto, Ontario, Canada, that corresponds to the boundaries of the City of Toronto prior to 1998. It was incorporated as a city in 1834, after being known as the town of York, and being part of York County. Toronto periodically grew in size by annexing adjacent land and municipalities.

Chloramination
Chloramination is the treatment of drinking water with a chloramine disinfectant. Both chlorine and small amounts of ammonia are added to the water one at a time which react together to form chloramine (also called combined chlorine), a long lasting disinfectant. Chloramine disinfection is used in both small and large water treatment plants. Use In the United States, the maintenance of what is called a "residual" of disinfectant that stays in the water distribution system while it is delivered to people's homes is required by the Environmental Protection Agency (EPA). The EPA regulations give two choices for disinfectant residual — chlorine or chloramine. Many major water agencies are changing to chloramine to better meet current and anticipated federal drinking water regulations and to protect the public health. Chlorine versus chloramine There are many similarities between chlorine and chloramine. Both provide effective residual disinfection with minimal risk to publ ...
