The City of Ottawa sources its drinking water from the Ottawa River and employs a comprehensive multi-step purification process to ensure water safety. Initially, water enters the treatment plant where large objects are removed.
8.Distribution
cleans water is pumped through more then 3,000 km of water
mains-roughly the distance between Ottawa and Calgary.
Approximately 250 million stress of of water is stored each day in
7. Testing
More than 100,000 tests are performed each year to make sure your tap water is safe. Water quality is tested at each
treatment stages and at more then 50 locations across the city
6.pH Correction
The water's pH is adjusted to protest water pipes and household plumbing from corrosion
5. Primary Disinfection
Chlorine is added to gets rid of any remaining microorganisms
4. Filtration
water then flows through several filters removing 99.99% of fine particles
3.Sedimentation
Heavy particles sink to the bottom of the setting tanks and clear water is collected from the top. Approximately 95% of the impurities are removed at this stages
2.Coagulation & Flocculation: Small impurities such as organic matter, algae, and bacteria are captured
1. Ottawa River water enters the treatment plant through a
large intake pipe with a screen that removes objects such as weeds or fish
its a long process to make sure the water we drink is free
of bacteria that can harm us
