Don't Pay for Water. Save Money.

It takes a lot of water to stay alive.  It shouldn't take a lot of money.  For those not fortunate enough to get their water from a well, the law provides a convenient and free method of boosting your retirement nest egg.  Specifically, regarding places of employment, OSHA Standard number 1910.141(b)(1)(iii) states,

"Potable drinking water dispensers shall be designed, constructed, and serviced so that sanitary conditions are maintained, shall be capable of being closed, and shall be equipped with a tap."

You can also get your water from precipitation, runoff and streamflow,

 before it ends up in the ocean to repeat the water cycle.

As long as you have a job in the U.S., you have access to clean tap water.  Every day when you go to work, fill a water jug for home hydration and start saving. Remember to take extra for the weekend!

Your cost savings will depend on how much money you wasted before changing your water habits.  Assume a typical male and female couple living together collectively drinks 5.2 liters (1.374 gallons) per day to stay alive at a cost of $0.02 per gallon.  This comes out to only $0.027 per day, but over the course of a whole year, this quickly adds up to a total of $10.03.  Like all investments, the earlier you start, the bigger you save.  If you can keep this up for 40 years till retirement, you'll have an extra $401.20 to your name.  Not bad for a simple life changing tip.
