# Navy Shower Analysis

December 5th, 2008 at 10:47 am

Curious to know what effect my navy showers would have on our water bill, I went into heavy-duty analysis mode.

* Got a five gallon bucket and measured the amount of water that runs from our shower head in one minute.
* Timed an average navy shower. Used the measurement to calculate the gallons of water used in an average navy shower.
* Guessed at the amount of time showering with a non-navy shower. Calculated the number of gallons used for that.
* Calculated the number of gallons used for a month of navy showers and a month of non-navy showers. Subtracted the navy shower gallons from the non-navy shower gallons to get the number of gallons saved per month of navy showers.
* Used the 7.481 gallons per cubic feet figure found in the Tightwad Gazette book to convert the gallons into cubic feet.

At this point I got out the most recent water bill, which covers two months, and made this startling discovery:
* Of the \$87.51 bill, \$57.20 are flat charges. No amount of decreased water usage will change them.
* In 56 days (per the bill), the amount charged for consumption was \$30.31. That's 54 cents per day.

Further calculations revealed that taking navy showers, at least in my part of the world, will decrease my water bill by about 0.83 per month, or about \$1.66 per bill.

I guess this experiment was not a stunning success. Nevertheless, I'm going to continue with navy showers. They help keep me in the frugal mindset.

I also plan to estimate the dollar savings of turning the heat down during the day while I'm home.

You're right Petunia; that was a thrill!

Bummer.

I don't mind Navy showers in spring or summer. I will do it to conserve water, regardless of cost. (Not that I did it every day; experimented).

But in winter, I am out. Hehe! Luckily here it is only 3 months out of the year it will be too cold (for me), probably.

It sounds like my "turn the hot water heater off at night" experiment. I checked kilowatts before and then checked them the next morning before turning it back on. I did the same the next night but this time left the h/w/h on. I repeated the experiment twice and the results were totally inconsistent with anything. Once it used MORE when I turned it off overnight. I then decided I was not scientific enough, because I hadn't paid attention to how many computers and/or tvs had been left on in each case, so I abandoned the whole experiment! I leave it on now, but I turn off the computers more. LOL

Monkeymama - Yes, I'm shivering as I'm waiting to jump in the shower. . . but if I time getting out with the heat coming on in the morning. . . or if I take my shower after DH takes his. . . or if I have a cup of coffee first, I do better. LOL.
