Treating Your Water
Why We Treat the Water
- To eliminate bacteria and microorganisms that may cause illness.
- To remove chemicals, metals and solids of concern from the water.
- To eliminate color, taste, and odour.
How We Treat the Water
We use multiple barriers in treating potable water to ensure the safety of your drinking water supply.
These barriers are:
Raw Material Intake: Withdraws water from the Red Deer River and removes sticks, branches and weeds through the screening process.
Low Lift Pump house: Water is transferred into the treatment plant and chemicals such as potassium permanganate and powder activated carbon are added for taste and odour control.
Clarification: A three step process which involves Coagulation, Flocculation and Sedimentation to remove larger partials from the water.
Filtration: Dual media filters are used to remove fine particulate matter from the water.
Chlorine Disinfection: Chlorine gas is used to reduce the bacteria and virus populations to safe levels.
UV Disinfection: Uses ultraviolet light to inactivate pathogens such as Giardia, and Cryptosporidium that maybe resistant to Chlorine disinfection. Inactivation prevents pathogens from reproducing.
Fluoridation: Fluoride is added to the water to help prevent tooth decay.
Water Stabilization: Caustic soda is added to adjust the treated water to an optimal pH to help control scale formation within the distribution system.
Chloramination: A small amount of Ammonia is added to form chloramine residual in the water. This provides a longer lasting disinfection in the distribution system.
