1. Water Biology What is the role of the water treatment facility? Elimination of biological activity in water Chlorination as a means of disinfecting water Dechlorination of water – one method

2. Our Local Treatment Facility: Where is it located? Where does the “raw” water come from?

3. Our Local Treatment Facility: What is in the “raw” water?

4. Our Local Treatment Facility: How much water is treated/day? Or /year? – Millions and millions of gallons or litres! Does it run 24 hours a day? – 24 hours a day/7 days a week

5. How is our drinking water produced?

6. Operation Water Biology Series of lab tests to demonstrate the water treatment process Tests will include: – Chlorination, ammonia, chloramine plus the uses and problems associated with each – Natural reduction and oxidation of iron and ammonia – Ways people can put bacteria to work – biological filters – Filter simulated well water – produced by you!
