Technical Tour 3 – Harris Water Treatment Plant

Monday 12 August

Time: 9:00 to 12:00

PAX: 40

Closed toe shoe required

The R.C. Harris WTP is an architectural masterpiece, designed in a classical version of the Art Deco style and is the largest unified ensemble of Art Deco Buildings in Toronto. The facility is designated under Ontario’s Heritage Act “as being of historical and architectural value.” Inside and out, the plant features stepped or set-back profiles and a wealth of flattened, geometric and highly stylized ornament in stone, brick, and metal. The plant is an excellent large scale example of how the Art Deco Style (1925-40) could integrate Late Romanesque Revival and Modern Classical forms.

The site was declared a National Historic Civil Engineering Site and recognized as a Canadian Water Landmark by the American Water Works Association. In 2011, Canada Post introduced a series of five domestic-rate stamps show-casing some of Canada’s finest Art Deco masterpieces, including this plant.

The R.C. Harris Water Treatment Plant (WTP) is located in the Beaches neighbourhood of Toronto. It is surrounded by residential areas to the north, east, and west and Lake Ontario to the south. The plant treats water from Lake Ontario and supplies safe and high quality drinking water to Toronto and York Region. The R.C. Harris WTP produces roughly 33 percent of the City of Toronto’s drinking water.

The plant was constructed in the 1930s and commissioned in 1941. Dubbed “The Palace of Purification”, this facility is a conventional filtration plant which was initially rated at a capacity of 100 million gallons (455 million litres) per day. When the Municipality of Metropolitan Toronto was created in 1954, a wider service delivery area was established to continue to provide an adequate supply of drinking water to a growing population. The plant underwent a series of expansions to achieve the current rated treatment capacity of 950 million litres per day (ML/d). It is Toronto’s largest water treatment facility and produces roughly 33 percent of the City’s drinking water.

Technical Tour 9 – Woodward Water and Wastewater Treatment Plants

Friday 16 August

Time: 9:00-17:00

45 PAX

Closed toe shoes required

Museum tour & lunch included

Hamilton’s Woodward Ave. facility is uniquely home to Hamilton’s Water Treatment Plant, one of two Wastewater Treatment Plants in Hamilton and the Steam Museum.

 

Woodward Avenue Water Treatment Plant

The Woodward Drinking Water Subsystem supplies a significant portion of Hamilton’s population with drinking water including Stoney Creek, Dundas, Ancaster, Waterdown, and Glanbrook. In 2022, the population services was estimated at 536,917. In addition, the treatment system provides treated water to parts of Haldimand County (Caledonia, York, and Cayuga) and parts of Halton Region. The Woodward Water Treatment Facility has three raw water intake pipes. The raw water is available to be drawn from Lake Ontario at distances of 640m, 915m and 945m to begin the treatment process.

Water Treatment Process:

  • Chlorine is added at the raw water intakes for zebra mussel control.
  • Screening takes place at the low lift pumping station prior to the water being pumped to the water treatment plant.
  • At the pre-treatment stage Polyaluminum Chloride is added to the water to coagulate suspended solids. Additional chlorine is also added at this stage to ensure disinfection.
  • Clarification of the water is completed by flocculation & sedimentation.
  • Chlorine, ammonia, fluoride and orthophosphate (phosphoric acid) are added before the treated water is sent to the distribution system. Ammonia is added to convert chlorine to mono-chloramine to help maintain stable chlorine residuals in the distribution system. Fluoride is added to the drinking water to promote dental health and orthophosphate (phosphoric acid) is added to help reduce lead corrosion.
  • High lift pumps push the water from the Woodward Water Treatment Facility to the distribution system.

The water treatment plant has a rated capacity of 909,000 m3/day (200 million gallons per day) and operates between one-quarter and one-third of its capacity.

The current treatment plant is adjacent to Hamilton’s Original Waterworks facility, which opened in 1859. It is recognized as a National Historic Site and currently operated as the Hamilton Museum of Steam and Technology.

Woodward Avenue Wastewater Treatment Plant

The Woodward Avenue Wastewater Treatment Plant services a population of approximately 512,363 (96% of Hamilton). The treatment plant began operation in 1964 with the original facility consisting of a main pumping station, bar screens, grit removal, primary clarifiers, and a sludge digestion system. Biological secondary treatment was added in 1972 at a cost of $23 million with the addition of eight mechanically aerated basins and eight final clarifiers. As a part of the Woodward Upgrade Project, in October 2022, a new tertiary treatment system, chlorine contact tank, and plant effluent outfall were placed in service, from which point secondary effluent receives addition treatment through cloth media disk filters improving effluent quality by further reducing total suspended solids and phosphorus loadings before discharging into the Red Hill Creek. The Woodward Avenue Wastewater Treatment Plant is now home to the largest tertiary treatment facility in Canada with the largest Aqua MegaDisk® cloth media filter installation in North America.

Steam Museum

The Hamilton Museum of Steam & Technology, also known as the “Steam Museum”, is located adjacent to the water treatment plant.  This National Historic Site is recognized as a civil and power engineering landmark.  Today the museum preserves two massive steam-powered beam engines, which pumped water in Hamilton from 1859 to 1910, as well as a collection of artifacts relating to Hamilton’s industrial past.  The museum interprets Hamilton’s relationship with water, steam power, and industrialisation.
