2. Presentation Preview Background to water treatment Background to water treatment Project fundamentals Project fundamentals The significance of our project The significance of our project Design Design –Project Statement –Alternatives –Implementation

3. Background: Wastewater treatment Wastewater Treatment Plant Influent Sludge Effluent Watercourse Dilution Typical wastewater system Typical wastewater system

4. Background: Water Treatment Raw Water Water Treatment Plant Potable Water Sludge “Indirect wastewater reuse” “Indirect wastewater reuse” Raw Water Source

5. Project Fundamentals Influent Wastewater Reuse Plant Sludge Potable Water “Direct wastewater reuse” “Direct wastewater reuse” No watercourse natural purification No watercourse natural purification WWTP and WTP condense into one plant WWTP and WTP condense into one plant

6. The Importance of Reuse Water shortages are increasing Water shortages are increasing –Groundwater, surface water, desalination Water conservation is necessary Water conservation is necessary

7. Project Statement To research and design a wastewater reuse plant that produces potable water that meets potable water quality standards. To research and design a wastewater reuse plant that produces potable water that meets potable water quality standards.

8. Project objectives Meet a need somewhere Meet a need somewhere Focus on environmental impacts Focus on environmental impacts Utilize cutting-edge technology Utilize cutting-edge technology Expand knowledge of water chemistry Expand knowledge of water chemistry
