Water Treatment Process

Windsor Utilities Commission, an industry leader throughout North America, is home to a superior water treatment facility that utilizes one of the top processes for purifying water — Ozonation. Using Ozone as a purifier is regarded as the best water treatment process there is. The water in Windsor is so pure that in studies conducted on bottles of water from local grocers, the tap water in Windsor outperformed in every area.

What is Ozonation?

Ozone is one of the strongest oxidizing agents that is readily available. It is used to reduce colour, eliminate organic waste, reduce odour, and reduce total organic carbon in water.

OZONE is generated by passing oxygen gas inside the ozone generator; this process is called Corona Discharge. Ozone is injected into the water through diffusers and the ozone gas reacts instantly to eliminate anything that could cause a disease within the raw water.

After the ozone is finished treating the water, any excess ozone is eliminated by treating it with a chemical called calcium thiosulphate.

The treated water then moves into tanks where additional chemicals are added to gather small particulates, forming heavier particles. The water containing these heavier particles then moves into a settling tank where the heavy particles settle to the bottom and the clean water is then sent to filters that do a final clean-up of the water.

The final treatment step is to add chlorine to the water (Chlorination); this helps to maintain the integrity of the water, even when it is going through old pipes.

What is Chlorination?

Chlorination is a water treatment process that destroys disease-causing bacteria, nuisance bacteria, parasites, and other organisms; it also removes soluble iron, manganese, and hydrogen sulfide from our water. We use the process of chlorination because it prevents disease-causing bacteria from infecting us, our pets, and other animals. Some of the diseases it protects against include typhoid fever, paratyphoid fever, bacillary dysentery, and infectious hepatitis, as well as many others.

Chlorine also:

  • removes unpleasant tastes and odours that come from algae and decaying natural vegetation in water distribution systems
  • controls microorganisms such as slime bacteria, molds, algae, and fungi that tend to grow on the walls in transmission mains and treatment basins
  • eliminates or reduces organic coloration
  • destroys hydrogen sulfide and removes ammonia and other compounds that have unpleasant tastes and impede disinfection.

After this process has been completed, the clean water is sent out to the residents of Windsor.

The Albert H. Weeks Water Treatment Plant supplies approximately 125 million Litres of water to City residents per day — and even more than that in the summer?
