1 A Tour of Denver Water Daniel Cromer Kellene McKinney Kristen Potter Lynn Pruisner Alex Ream Pam Morse, TA Introduction to Chemical Engineering Group 6April 11, 2007

2 WaterA Universal Product 70% of the earth is covered with water.

3 WaterA Universal Product 70% of human body mass is water.

4 WaterA Universal Product The average consumption is 168 gallons per day per person.

5 WaterA Universal Product Water is necessaryeveryone needs it!

6 The Water Business Collection Purification Distribution Future Planning

7 Source Water Collection Mountain Snowmelt* Streams & Rivers Dams Reservoirs Recycled Water

8 Purification From Mountain Top to Tap Removing Contaminants Potable & Nonpotable Water Standards Turbidity ( )

9 Distribution Complex Network of Pipes Deliver to Homes Businesses Industry Fire Hydrants

10 Denver Water Denver Metro Area Water Service provided by

11 A Brief History of Denver Water Colorados Oldest and Largest Established 1918 when Denver Union Water System was purchased for $14 Million

12 Fun Facts about Denver Water 2,631 miles of pipeline 34 Underground Reservoirs Fill INVESCO Field 2x per day Serves 25% Colorado Population 15,000 Fire Hydrants

13 Denver Water People Controls Engineer* Electrical and Civil Engineers* Water Treatment Technician Water System Operator Dillon Reservoir Caretaker Ground Laborers Human Resource Specialist

14 Denver Water Facilities Main Plants Marston, Moffat, Foothills Recycle Plants Commerce City Completed 2004$180 Million

15 What is a Recycle Plant? Process Lower Quality Source Efficient Production for Nonpotable Uses Reuse Metro Wastewater Mediates Drought Problems Popular Worldwide

16 Denver Water Recycle Plant The Purple Pipes Saves Money and Potable Water Customers: Xcel, Denver Zoo, Golf Courses Model Recycle Plant for Cutting-Edge Water Treatment

17 Analysis Lab On-site and Fully Equipped Accessible SamplesAny Stage Organic and Inorganic Analysis

18 Control Room 24/7/ Computer Controlled Full Monitoring: Data, Trends, Video Security

19 Location and Layout Commerce City, CO Near Large Industries Platte River Linear Flow

20 Recycle Plant Process Collection Bio Process Coagulate Flocculation Sedimentation Filter Disinfect Storage

21 Recycle Plant Process Collection Bio Process Coagulate Flocculation Sedimentation Filter Disinfect Storage Source Water Metro Wastewater Collected pH Balanced with NaOH Ammonium Hydroxide added as nutrient for bacteria

22 Recycle Plant Process Collection Bio Process Coagulate Flocculation Sedimentation Filter Disinfect Storage Biological Filters Bio-Bacteria Sodium & Ammonia Nitrates Watch what you put in! Disturbed biomass shuts down the plant for a week while they replenish themselves.

23 Recycle Plant Process Collection Bio Process Coagulate Flocculation Sedimentation Filter Disinfect Storage Mixing/Particle Removal AlumCoagulant Coagulates small particles Open to the air Often have fish and or ducks in the water

24 Recycle Plant Process Collection Bio Process Coagulate Flocculation Sedimentation Filter Disinfect Storage This process rids the water of most large particles including the alum. Inside and covered Flocculation

25 Recycle Plant Process Collection Bio Process Coagulate Flocculation Sedimentation Filter Disinfect Storage Remove any large particles that made it through flocculation. (Fish, Light Particles) Everything was covered in a layer of rust. (Not everything filtered) Sedimentation

26 Recycle Plant Process Collection Bio Process Coagulate Flocculation Sedimentation Filter Disinfect Storage Filters Filters out the very small particles left in the water to make extremely clear water (turbidity < 0.5) Made of anthracite (a very hard pure form of coal) Troughs spread the water out so that the filter is used evenly

27 Recycle Plant Process Collection Bio Process Coagulate Flocculation Sedimentation Filter Disinfect Storage Disinfect and Store Chlorine disinfects water Stored in large (300 x 23 ft) round storage tanks. 11 million gallons Stored under parks or other large open spaces Pumped out to customers

28 Impressive Plant Beautiful architecture Everything color coated Cleanliness a priority Separate buildings keep things organized and cost efficient

29 Future Planning Changing Quality Standards High Security/Safety Bad Chemicals: Unsafe water in Denver homes and establishments

30 Future Planning Limited Potable Water Multiple Water Mains Conservation and Education Note: Use only what you need!

31 Constant Expansion 2007 Pump Station, Distribution Pipes, Storage Facilities 2010 Additional Water Mains

32 Conclusion Potable or nonpotable, the water is clean! Thank you! Acknowledgements Denver Water Pam Morse CHEN 1300 University of Colorado
