Using Greywater from your Washing Machine

With our current bad drought conditions it makes no sense to pour perfectly good water down the sewer. So we just joined the greywater underground with our illegal washing machine surge tank, and the installation was a piece of cake.

We built our washing machine surge tank based on the design in Art Ludwig’s book Create an Oasis with Greywater. The purpose of the surge tank is to prevent the built-in pump in the washing machine from burning out, which might happen if you tried to pump the water through pipes. The tank also slows down the flow of water going out to the garden, allowing more time for it to percolate into the soil. In addition the tank lets the water cool a bit, should we run a load in hot water.

For the tank we picked up a used and cleaned 55 gallon plastic drum with two “bung holes”, and plumbed it based on a design from Aquabarrel.com. The folks at Aquabarrel offer kits or a DIY video. We put our barrel together ourselves with a couple of common pvc fittings from the hardware store and omitted the overflow pipe, since our washing machine load will never exceed 55 gallons. The basic idea behind the Aquabarrel design is to turn the barrel upside down and use the preexisting threaded bung holes to connect up a garden hose. It took just a few minutes to complete, and our washing machine surge tank was ready to use. We highly recommend the Aquabarrel design, and you could combine a washing machine surge tank with a rain barrel with the addition of the overflow pipe and a fitting for the gutter.

When we do a load of laundry the waste water that collects in the barrel flows immediately out the garden hose and down towards the front slope of our little compound. Ludwig warns against keeping grewater around as it will quickly turn septic. We use Oasis Biocompatible detergent which is manufactured specifically for greywater systems. Regular “eco” detergents, while not harmful to aquatic plants, often contain substances that will kill terrestrial plants so you must use a greywater specific detergent.

Our next step will be to figure out some plantings that will take advantage of our laundry schedule, and to construct some simple earthworks and mulch basins to accommodate the water flow. Right now we just let the water percolate into the front slope, and our rosemary and Mexican sage look a lot healthier for it.

Chicken Guantanamo

So you want your own backyard hens? Some time ago Homegrown Revolution reader Toby asked about what it takes to keep chickens. While we’re far from being experts we thought we’d share what we’ve learned so far and welcome comments and suggestions from poultry keeping readers to add to and amend our advice. In our opinion the first step in keeping a backyard flock is to figure out where you’re going to house them.

We’ll get into more detail over the next few months, but for now we thought a few pictures might help explain what we’ve come up with. The two main purposes of chicken housing are to protect them from predators and to protect your garden from destruction by your chickens. The more room and foraging area your chickens have the happier they will be. Give them access to your whole yard however, and they will munch and scratch down every plant they find edible behaving, as the Petaluma Urban Homesteaders put it, “like a pack of delinquent teenagers”.

Our chicken housing consists of three zones. Zone one is the hen house–that aluminum structure on the right in the photo above. It contains a roost for the chickens to sleep on at night and a nesting box for the hens to lay their eggs in.

Zone two is a secure run covered in 1/2 inch hardware cloth–the area left of and below the aluminium sided hen house. We used hardware cloth because chicken wire will not prevent raccoons from reaching in and eating a chicken through the fence (we can’t help but admire the fact that chicken wire isn’t really good for keeping chickens). And as our doberman has been known to tree large families of raccoons, we took no chances and ran the hardware cloth across the entire bottom of the run buried a foot underground to keep these critters from burrowing underneath. The run also gives our hens access to dirt as well as a way for us not to have to be around to lock them up in the hen house when it gets dark.
Zone three is a mobile structure made of PVC pipe covered with bird netting and butted up against the coop and secure run so that the hens can move between all three zones. We used to let the hens free range around the yard, but a recent near miss with a hawk, the general devastation of our herb bed, and chicken poo all over the back porch where they took to roosting on lazy afternoons, convinced us to restrict their movements at least while unsupervised. This PVC structure can be shifted around a bit to let the hens work different parts of our small backyard. It will keep out hawks but it’s not raccoon proof, so the girls must be back in zone two’s more secure run (nicknamed “chicken Guantanamo”) when it starts to get dark or we’re not around.

The PVC structure replaces a more permanent enlarged run we built out of scrap wood we found under the 101 freeway. As you can see from the photo below, this structure was an aesthetic disaster, with all the appeal of a dirty mid-town mini mall. We took one look at it after it was complete and decided to demolish it the next day. If only all those mini mall developers in the 80s would have come to the same conclusion.
We’ll describe our hen house, run and “zone three” in more detail once we know everything works out. So far, we’ve got eggs and no raccoon, skunk, owl or hawk casualties. For those looking for detailed plans check out Judy Pangman’s book Chicken Coops: 45 Building Plans for Housing Your Flock. We loosely based our coop and run on one of the designs in Pangman’s book. Stay tuned for more details including our ongoing attempt to stay one step ahead of those bad-assed LA raccoons.

The one-hour program consists of short films on a variety of topics including urban gardening, environmental awareness and community activism. In keeping with the grassroots nature of many of these organizations, emphasis is on issues awareness, practical information exchange and hands-on participation.

And on the Seventh Day Petals Fell in Petaluma

The ducks of Petaluma Urban Homestead

A big thanks to Suzanne and Paul of Petaluma Urban Homestead for giving us a tour of their bit of heaven on earth. Root Simple forgot to bring the camera so you’ll have to check out their blog to see what they are up to. They make a damn good hard cider by the way.

We also had the privilege of meeting the inspiring Trathen Heckman of Daily Acts, publisher of the journal Ripples. If that wasn’t enough, Suzanne took us to an open house at the Center for Regenerative Design to see the wonders of permaculture applied to the breathtaking northern California landscape.

We’re back and fired up to work on our own humble plot here in Los Angeles which is looking a little neglected after a busy fall. More soon . . .

Breaking News

Today at approximately 11:50 AM, after a morning of god-awful screeching, our Rhode Island Red, Stewpot–who is in the foreground of the picture above–laid her first egg–that is, our very first homestead egg.

Go Stewpot!

Of course this event would happen when Mr. Homestead is out of town & in possession of the camera. The lay site was a difficult to access cranny behind the coop. It may not have been photograph-able anyway, but I will report that the egg was deposited quite attractively in a shallow bowl of yellow and brown leaves. I got it while it was still warm, having come out to see what this most recent and particularly loud round of screeching was all about. Stewpot walked away from her egg with nary a look back. The egg was amazing in the hand–warm and heavy and almost pulsing with life.

To mark this historic day, I did what I could to record the blessed egg: I scanned it alongside a Trader Joe’s grade A brown for comparison, which resulted in the mysterious, murky image you see below.

Stewpot’s egg is smaller than the commerical egg, but it is her first. Her egg looks the same color at first, but close up it is covered with tiny brown speckles, whereas the Joe’s egg is more monotone.
