1. The Green Shower: Saving Water Before the Shower Begins  Team 2-2: Mike Noce (Captain) Karl Buhariwala Andy Ong Josh Atzert

2. Problem Background http://www.biblepicturegallery.com/free/Pics/Global.gif  On average 3000 gal of water is wasted by a family of 4 per year

3. Problem Background http://www.biblepicturegallery.com/free/Pics/Global.gif  On average 3000 gal of water is wasted by a family of 4 per year  Some repercussions may include salt water encroachment, and lowering of the water table

4. Problem Background http://www.biblepicturegallery.com/free/Pics/Global.gif  On average 3000 gal of water is wasted by a family of 4 per year  Some repercussions may include salt water encroachment, and lowering of the water table  Fresh water is essential for humans

5. Problem Statement http://www.greywater-systems.com/047902a0.jpg : Modified by Karl Buhariwala  Major source of water waste: water cooling down in the hot water pipe

6. Problem Statement  Major source of water waste: water cooling down in the hot water pipe  People drain this water before they start their shower http://www.greywater-systems.com/047902a0.jpg : Modified by Karl Buhariwala

7. Solutions  Small water heater in each bathroom

8. Solutions  Small water heater in each bathroom  Recycling system that uses water that goes down the drain

9. Solutions  Small water heater in each bathroom  Recycling system that uses water that goes down the drain  Temperature regulating water collection tank behind the wall

10. Water Heater  Heaters switched on before shower and off after http://www.eurouno.com.my/images/installguide_wh_1 5.jpg

11. Water Heater  Heaters switched on before shower and off after  Large amounts of electricity lost: 2 kWh /10 gal http://www.eurouno.com.my/images/installguide_wh_1 5.jpg

12. Water Heater  Heaters switched on before shower and off after  Large amounts of electricity lost: 2 kWh /10 gal  Piping and wiring could be quite costly http://www.eurouno.com.my/images/installguide_wh_1 5.jpg

13. Recycling System  Water can be reused throughout household

14. Recycling System  Water can be reused throughout household  Calls for a completely separate piping system dedicated to recycling

15. Recycling System  Water can be reused throughout household  Calls for a completely separate piping system dedicated to recycling  Could require pumps to be reused in multiple water systems

17. The Green Shower  A 600 in 3 water tank is placed behind the wall of the shower

18. The Green Shower  A 600 in 3 water tank is placed behind the wall of the shower  The cold water is collected in the tank

19. The Green Shower  A 600 in 3 water tank is placed behind the wall of the shower  The cold water is collected in the tank  The hot water raises the cold water to the desired temperature

20. The Green Shower  A 600 in 3 water tank is placed behind the wall of the shower  The cold water is collected in the tank  The hot water raises the cold water to the desired temperature  Conventional override kicks in

21. Diagram of Solution Adams

22. Criteria for Success  Solution must end up saving as much as water and energy as possible

23. Criteria for Success  Solution must end up saving as much as water and energy as possible  The changes that would be made to the conventional shower should be minimal

24. Cost

25. Recommendations for Future Work  Save as much water as possible http://www.cshp-bc.com/events/2005_Events/AGM05/thinking_man2.jpg

26. Recommendations for Future Work  Save as much water as possible  Cost efficiency http://www.cshp-bc.com/events/2005_Events/AGM05/thinking_man2.jpg

27. Recommendations for Future Work  Save as much water as possible  Cost efficiency  Develop Electronics http://www.cshp-bc.com/events/2005_Events/AGM05/thinking_man2.jpg

28. Summary  766 gallons of water is wasted each year per person and this can be saved

29. Summary  766 gallons of water is wasted each year per person and this can be saved  The Problem: Water wasted in a shower

30. Summary  766 gallons of water is wasted each year per person and this can be saved  The Problem: Water wasted in a shower  Solution: The Green Shower
