Water Conservation

“the price we paid was the price men have always paid for achieving a paradise in this life — we went soft, we lost our edge.”
-Frank Herbert Dune

SurviveLA was planning on discussing rainwater collection today, but we realized that we would be getting ahead of ourselves without first discussing what we call BOC, or boring old conservation. So before delving into greywater and rainwater harvesting it’s time to assess where your household is in terms of water consumption and see if that level can be reduced. It’s generally far easier and less expensive to conserve resources than it is to resort to the latest techno-eco-gadgetry.

So let’s count down the major sources of domestic water use (according to percentages calculated by the American Water Works Association Research Foundation) and consider how to conserve:

58.7% Outdoor Water
Clearly, the place to start with water conservation is outdoors, in designing a landscape that doesn’t need supplemental irrigation. Our rule around the SurviveLA compound is, once again, if you gotta water it you gotta be able to eat it. The vegetables that we grow are irrigated with a water-saving drip irrigation system that we’ll describe in detail in a later post. We have no lawn, and other than the vegetable garden, all the other plants are either natives or from the Mediterranean, many of which are also edible. Reusing greywater from your shower and washing machine can also reduce the amount of outdoor water usage. Above all remember that lawns are the wasteful and evil thought-spawn of generations of golf-obsessed Republicans. Replace them with edible landscaping, or decomposed granite.

10.8% Toilet
All toilets should be low-flush, and todays low-flush toilets are considerably better than the first generation. A low-flush toilet uses less than 1.6 gallons of water compared to 3.5 to 5 gallons for an old toilet, which many municipalities will give you a substantial rebate for getting rid of. If you live in an apartment or don’t have the energy to dump the old crapper, it’s possible to fill a plastic water bottle with stones and put it in the tank to displace and thereby reduce the amount of water used to flush. Don’t use a brick for this purpose since it can kick around and damage the flushing mechanism.

And remember the charming slogan, if it’s yellow let it mellow, if it’s brown flush it down. The mellow yellow strategy can save hundreds of gallons a year. This idea can be automated with a so-called dual flush toilet. These toilets, common in Europe, have two buttons–one for pee-pee and one for poop. Most dual flush toilets use the standard low-flush rate of 1.6 gallons when you hit the #2 button, but use only .8 gallons when you hit the #1 button.

And don’t use the toilet as a trash can. Not only does this waste water, but it puts an additional burden on sewage treatment plants. Having visited a sewage plant in person, SurviveLA can personally attest to the depressing sight of witnessing hundreds of plastic tampon applicators afloat in a vast sea of poo.

8.7% Clothes Washer
Wash only a full load. Run the waste water outside to irrigate your landscaping using either a surge tank, or directly.

Adventurous homesteaders, willing to put in the extra labor, may wish to consider a James Washer, an electricity free hand washer, commonly found in off-grid households, where you put some hot water in and agitate the clothes for a few minutes with a lever on the side. A hand wringer is used to dry the clothes before hanging them on a clothesline. A simple drain line can be hooked up to a hose and run out to the garden.

6.8% Shower
Shower less and celebrate your body odor–pretend you are the type of person Andy Warhol used to lovingly refer to as Eurotrash. Barring lifestyle changes, install a low-flow shower head. Also consider a shower head with a cutoff valve to allow stopping the water while soaping up. Use a bucket to catch the water that flows before it heats up. Use this water for plants or to “bucket flush” the toilet.

It’s cheating somewhat, but take your showers at the gym and let someone else pay for the water.

6.3% faucet
Turn off the water until needed when brushing teeth or shaving.

5.5% leaks
This is a no-brainer, but something everyone seems to forget. Fix leaks immediately! The knowledgeable folks at your local hardware store (not the idiots at Home Depot!) can tell you how.

.6% dishwasher
Run your energy efficient dishwasher only with full loads. And incidentally, a study conducted by the University of Bonn in Germany concluded that dishwashers use half the energy, one sixth the water, and less soap than hand washing.

One last sobering statistic to remember–the average American uses between 80 and 100 gallons per person per day, with the higher consumption coming from folks living in the dry Southwest. The average African uses 5 gallons a day.
