Water Timer(idea)

Math Project: Codename Showerhead Average time spent in shower (BBC): 8 minutes (16.4 gallons per minute) Average Gallons per minute (BBC): 2.05 Gallons per minute With the Shower Timer, which shuts off water after 5 minutes plus time needed for hot water to come up, you can save 6.15 gallons! 16.4-10.25 Average Dollars per Gallon: $0.01143 Money saved per shower: $0.072 per shower What: Shower Timer that Shuts off water after 5 minutes plus time needed for hot water Digital Made of Plastic with electronics inside Can choose heat with a knob Beeps every 1 minute and counts down in last ten seconds Who: Average family can buy $25 Must have plumber install due to have to be attached to pipes How: Shuts off water after 5 minutes no override Can be turned off earlier but not later Where: In shower Why: To save water and money Measurements: Base-4 inches, Width-3 inches, Height-3 inches, Surface Area-66 inches squared, Volume- 36 inches cubed

Step 1: Materials

•Tape measure •Circuit board •Wires •1 tube •tin foil •knife •Wood •Timer • Top to oil holder

Step 2: Measurements for Structure

Measure and trace your wood so you have 2 traced out 3x3 pieces of wood for the side, and then trace again for 4 pieces of 4x3 pieces of wood. Then when you got your pieces cut them out.

Step 3: Construction 1

When you have cut out all of our pieces, attach the circuit board to 1 4x3 piece of wood and then attach all of your pieces together. To make a rectangular prism. Put in your timer and wires and make sure that all are hooked up together properly. Make sure that there are no holes or gaps.

Step 4: Construction 2

Now cut a hole in the 4x3 piece of wood so the timer piece of the handle can be shown and used easily, and also to prevent water from leaking in after attaching metal top. Then, make 2 holes on the side with the 2 3x3 pieces of wood. This is so you can attach it with your shower instead of using the normal handles. Then eventually you have a shower timer.

    Did u mean we pay 16.4 dollars per gallon? Or was that cents? We pay 15.30 a month for 2 cubic feet of water which works out to be that's about .02 a gallon. We use a 2 gallon pan fill it half way full bring it to a boil and only use 2 gallons of water and still have a bunch left over. Your toilet uses more a day then your shower.
    Think about it if you have a family of 4 and your toilet uses 1.6 gallons and each person goes 4 times a day that's 30 or so gallons a day just in toilet waste water. Then all the water you use in a dish washer plus running sinks watering the yard, washing the car, and waste such as leaving it run when your brushing your teeth. Honestly there are a huge number of other places you could cut the water consumption compared to the sanitary benefits of a shower. You ever been to jail? Those are 5 minute timers and its hard to get wet, soaped let the soap sit and work then rinse off plus rinsing your hair. A women takes 5 minutes to rinse hair if its long and thick. Plus your using fissile fuel to make the electric to operate that water miser. Its just not feasible to have one to be honest, teaching good water habits is a better approach.
