The Green Shower: Saving Water Before the Shower Begins

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

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

3. Problem Background • 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 http://www.biblepicturegallery.com/free/Pics/Global.gif

4. Problem Background • 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 http://www.biblepicturegallery.com/free/Pics/Global.gif

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

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_15.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_15.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_15.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 in3 water tank is placed behind the wall of the shower

18. The Green Shower • A 600 in3 water tank is placed behind the wall of the shower • The cold water is collected in the tank

19. The Green Shower • A 600 in3 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 in3 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
