Siphon Your Bathwater

So it’s back to greywater today with a tip on siphoning your bathtub water. The concept goes like this. When you take a shower keep the plug in. Yes it’s a bit gross at first, but you get used to it. When you are finished, submerge a length of tubing in the bath water. Hold your finger over one end and pass it to an accomplice waiting outside in the garden. As long as your bathtub is higher than the part of your garden being watered, you will have created a siphon and the water will drain out of the tub.

Now if this sounds like a pain in the ass, or if you have no accomplices there is (or perhaps was as the website does not seem to be working) a siphon device on the market for just this purpose. Called the “Ban Beater” this siphon pump was being sold in the UK as a result of the draught that struck south-east England this year. However, this greywater siphoning tool is on the expensive side and it’s hard to justify spending a lot of money just to save a few cents worth of water, especially when the siphon devices themselves are produced with plastic and other petrochemical products. Devices like these suddenly become popular when governments institute water rationing as did the British earlier this year. There are less expensive siphoning devices available in hardware and auto parts stores made for siphoning gas, but SuviveLA has not tested them yet.

If siphoning is too much effort for ya, it’s time to move on to more permanent solutions involving rerouting your plumbing that we’ll get into in subsequent posts.

Greywater Precautions

Before we continue our greywater series, we have a few precautions to lay down. The dangers of greywater have been exaggerated in the past and it’s important to remember that nobody in the US has ever gotten sick from exposure to greywater. The plumbing codes in this country are overly cautious in their restrictions on greywater use, as the Man, quite simply, wants you to throw perfectly good water down the sewer. On the other hand, a lot of hippie types have been a little too loose with greywater and nasty bugs like e-coli, pictured on the right, remind us we need to be careful. So here are SurviveLA’s rules to follow when using greywater:

  • Do not apply greywater to crops that you will eat raw, such as strawberries, carrots or lettuce. Using greywater on any vegetables is somewhat dodgy in general for heath reasons, but greywater is fine for edible plants such as fruit trees where the crop is far from the ground and the risk of direct contamination by contact with contaminated water is low.
  • Do not apply greywater to lawns (lawns are evil anyways) or to the foliage of any plant as this can cause a microorganism growth party. Remember that greywater is treated by moving through soil.
  • Greywater tends to be alkaline, so avoid using greywater on acid loving plants such as citrus, ferns and other forest plants (pretty much anything that grows in the shade).
  • Occasionally irrigate your plants with fresh water to prevent the buildup of salts from soaps and detergents.
  • Do not distribute greywater with a sprinkler as you don’t want the potential bad stuff becoming airborne.
  • Do not use the water from your washing machine if you are washing diapers (gross!).
  • Do not allow greywater to stand as it will quickly become the perfect habitat for anaerobic bacteria which will quickly turn it into a stinky, mosquito and fly infested pool of blackwater. Plan a system that will, ideally, use your greywater immediately.
  • Use only detergents and soaps designed for greywater systems such as Oasis Biocompatible Cleaning Products.

Bucket Flushing

SurviveLA is researching greywater systems and today we’ve got our first tip on recycling your water. First a definition. Greywater is the waste water that comes out of your shower, sinks, and washing machine. Blackwater is the icky stuff that comes out of your toilet and because of the risk of contamination it should not be reused. For now we’ll lump the kitchen sink in with the toilet since food scraps, particularly for meat eaters can quickly turn your greywater into rancid blackwater.

Greywater systems range from the simple to the complex and we’ll start with the cheap and easy — bucket flushing. Simply keep a bucket next to the shower and collect the water that you run before the shower gets hot. Since you haven’t even stepped into the shower this water is pure water, and not even technically greywater. You can use this water on plants or to flush the toilet manually by pouring it directly in the bowl.

It’s also possible to disconnect the bathroom sink from the sewer system and send the water into a bucket that you keep under the sink. This water is greywater since it’s contaminated with soap and toothpaste, so don’t let it sit around for long or it will get stinky. If you disconnect your bathroom sink, make sure that you keep water in the trap (that u-shaped pipe), otherwise unpleasant sewer odors will fill your bathroom. Alternately, you can cap the sewer pipe or install a diverter valve.

One last warning. Apparently around twenty-five kids drown in buckets every year in the US, so don’t leave buckets unattended if you have little ones, though the danger is mostly from larger five gallon buckets.

So flush the SurviveLA way — bucket flush!

Street Signs and Solar Ovens

If SurviveLA put together a museum show it would, pretty much, look like an exhibit currently at the Craft and Folk Art Museum entitled “Street Signs and Solar Ovens: Socialcraft in Los Angeles” which is on view until December 31st. Curated by the Journal of Aesthetics and Protest, this timely show focuses on objects that demonstrate creative, low-tech solutions to the environmental and political mess we find ourselves in.

We were particularly struck by the display case full of soda cans transformed by LA survivalist Christopher Nyerges into a variety of uses including lamps and stoves (see SurviveLA’s earlier post on creating a Pepsi can stove). Nyerges also contributed two improvised solar ovens, one made out of a discarded pizza box.

Other highlights include a functioning still by Alison Wiese, the stunning knitted clothing of Lisa Auerbach, items from the Path to Freedom urban homestead and contributions from the fine folks at C.I.C.L.E.

So, get on your bike, head down to the Craft and Folk Art Museum, and see this provocative show!

Suntracker

Brief linkage today. While Homegrown Revolution doesn’t like to overdo the technology thing, we think this natural light collecting skylight device called the Suntracker One has promise. Similar in principle to the Solatube, the Suntracker, as the name implies, has an additional feature that the Solatube lacks — it tracks the sun with a built-in electronic brain and mirrors. Both the Solatube and the Suntracker direct the light down a tube, thus replacing the heinous blocks of fluorescent fixtures that typically light most commercial buildings with a more aesthetically pleasing natural light. Solatubes are available for residential use, but the Suntracker is oriented towards larger commercial applications.
