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

Problem Background  On average 3000 gal of water is wasted by a family of 4 per year

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

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

Problem Statement : Modified by Karl Buhariwala  Major source of water waste: water cooling down in the hot water pipe

Problem Statement  Major source of water waste: water cooling down in the hot water pipe  People drain this water before they start their shower : Modified by Karl Buhariwala

Solutions  Small water heater in each bathroom

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

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

Water Heater  Heaters switched on before shower and off after 5.jpg

Water Heater  Heaters switched on before shower and off after  Large amounts of electricity lost: 2 kWh /10 gal 5.jpg

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 5.jpg

Recycling System  Water can be reused throughout household

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

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

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

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 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

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
