Water Treatment Plant Information

The Swift Current Water Treatment Plant serves water to the City and several outlying residents in the Swift Current RM. The water source is the Duncairn Dam which supplies water to the Swift Current Dam. The plant, which is located at the Swift Current Dam, treats and pumps water into the distribution system via South Hill Reservoir.

The Process

Pre-treatment

The process of the water treatment plant involves multiple physical and chemical treatments. The first section of this process is the pre-treatment of the water. Two chemicals are used here. The first is Potassium Permanganate which removes manganese, and reduces tastes and odours. This is followed by Powder Activated Carbon. The carbon removes some disinfection by-products and treats seasonal tastes and odours.

Primary Treatment

Pre-treatment is followed by Actiflo clarifiers for primary treatment. Primary treatment is coagulation and ballasted flocculation. The Aluminum sulfate is added to help particles in the water to collect and stick together. This process is called coagulation. Carbon Dioxide is added to reduce the pH of the water, allowing the aluminum sulfate to be more efficient. This is quickly followed by ballasted flocculation when a polymer and Microsand are added to make the coagulated particles heavier.

3

Filtration

After the Actiflo clarifiers the pH of the water is adjusted up with sodium hydroxide to a neutral pH of 7.0 and filtered. The filters take out any particles that were not taken out during primary treatment.

Disinfection and Fluoridation

After filtration, chlorine is added for disinfection. Fluoride is added for dental hygiene. This is followed by ultraviolet disinfection which will inactivate any living cell that has not been killed by the chlorine.

Distribution

After the water is disinfected, it is pumped in South Hill Reservoir. South Hill holds around 6,800,000 liters of water. From South Hill Reservoir the water is pumped into the water distribution system and North Hill Reservoir. North Hill Reservoir also holds 6,800,000 liters.

Winter average usage is around 6 million liters of water per day. Summer usage is around 12-15 million liters per day with peak times reaching above 22 million liters of water.

The max flow rating for the plant is 30 million liters per day.

Latest Upgrades

2012 – Extensive remodeling done. Actiflo clarifiers with pH adjustment and Ultraviolet (UV) disinfection were added. Along with a new laboratory and chemical storage facilities.

Treated Water

Raw Water Source and Supply Source - Duncairn Dam Supply - adequate for 2019 2019’s treated water pumped was average, comparable to 2013 and 2015 treated water pumped. July of 2017 was the highest treated water pumped since July of 2006. July was hot and dry, with half of the days having temperatures over 30 degrees.
