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.

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.

It’s always been fun to stick it to the Man

The folks from Dough on the Go! were over the other night and reached into a box of slides we found years ago at a thrift store and never looked at. That box turned up these images showing a previous generation enjoying the “water of life” coming out of what appears to be two different home built stills. Homegrown Revolution applauds the DIY spirit (so to speak) and these images seem an appropriate way to begin the dreaded holiday season.

Our Rocket Stove

 
  • Editor’s note: we have a new design for a portable rocket stove here.

Low-tech is the new high-tech, and the best example of the low-tech revolution is the miraculous rocket stove–a stove that makes it possible to cook with small twigs–no logs needed! Best of all rocket stoves are easy to build. We liked the idea so much that we decided to build a permanent one just off our back deck for entertaining and as a backup to our gas stove should an emergency take out our utilities.

The rocket stove was developed for use in poor nations where wood used for cooking has led to the vast, wholesale, deforestation of large swaths of the earth’s surface. Rocket stoves can be built out of metal or masonry and consist of a L shaped tube, at the bottom of which you place your wood. The chimney effect creates a highly efficient, largely smoke-free burn. There’s no need to cut down a tree to cook your dinner–all you need is a few small branches or twigs.

Before we built the rocket stove we considered making a cob oven, a mud domed wood fired oven in which you can cook bread and pizza. There’s a trend in the eco-world to build cob ovens and we felt a certain pressure to keep up with the eco-Joneses. We started to build the base for one and then began to think about how often we would actually build a fire, especially considering that it has to burn for several hours before a cob oven gets hot enough to cook in. Also, where would we get the logs? And how good is it to burn such a fire and contribute to Los Angeles’ already smog choked air?

Staring at the bricks we had scavenged to build the base of cob oven, we realized that we could re-purpose them for a permanent backyard rocket stove that we would actually use. Furthermore we realized that our rocket stove could burn some of the palm fronds that regularly tumble down from the iconic palm trees that line our old L.A. street.

Here’s the materials we used:

36 bricks
4-inch galvanized steel stove pipe elbow
4-inch stove pipe
ash (scavenged from park BBQs)
1 tin can
50 pound bag of premixed concrete for the base
mortar mix
grill (scavenged)

The first step was to make a small foundation for the rocket stove. We fashioned a 18 by 18-inch by 4-inch slab with 2 x 4 lumber and a bag of premixed cement. Folks in cold places will need to make a deeper foundation to avoid frost heave.

Next we built a brick cube, leaving a small hole for the bottom of the stovepipe. For advice on how to build with brick we recommend taking a look at this. As you can see our masonry could use some more practice, but the results are not too bad–we like to think of our stove as being a bit “rustic”. You can avoid the hassle of brickwork by making a simpler rocket stove–check out these two instructional videos, one for a metal model, and another version using bricks. We chose brick largely for aesthetic reasons and we’re satisfied with the results.

Drawing from Capturing Heat

The next step is to put the pipe together fitting the elbow up into the longer pipe, and sized so that the top of the pipe is just below the bottom of the grill. Check out our earlier post for a video that can help with this part of the assembly. Serendipitously, on a bike ride, we found a grill in the middle of Sunset Boulevard that fit the opening in our brick rocket stove exactly.

You pour the ash into the completed brick cube to fill the space between the pipe and the inside wall. The ash acts as insulation to increase the efficiency of the stove. You could also use vermiculite but note that sand or soil will not work. Insulation works because of small pockets of air between particles, hence the need for ash or vermiculite, which are also non-combustible. We used a piece of scrap sheet metal with a 4-inch circular hole cut in it to keep the ash from spilling out the gap between the pipe and the squarish opening at the bottom.

Lastly you use a tin can sliced down the side and flattened out to form a shelf which you insert into the elbow at the bottom of the stove. Note the drawing above for the shape of the shelf. You put your twigs and kindling on this shelf and start the stove up with newspaper underneath the shelf. As the twigs burn you push them in over the edge to keep the fire going.

Our first test run of the stove was very successful–we boiled a pot of water and cooked some eggs in a a pan. The fire burned cleanly with little smoke except during start up. For more info on rocket stoves check out the Aprovecho Research Center.

And please people don’t burn wood inside and watch out for embers. Make sure you put the fire out completely when you are done cooking!

It Quacks Like a Duck


The Happy Ducks of the Petaluma Urban Homestead

It seems a new lifestyle is taking shape, in part born of the ashes of the World Trade Center, the aftermath of Katrina, and the endless resource wars our country feels the need to fight. There’s a great desire out there to “do something” and a refreshing DIY spirit of self-sufficiency is beginning to emerge. Two of the indicators of this new lifestyle seem to be the mixture of poultry and bicycles, a combo that we seem to share with a surprisingly diverse group of people, including our bike activist friends at C.I.C.L.E. and our bike safety instructor Chris Ziegler.

A surprise phone call we received this week, after some musings of our appeared in Ripples Magazine, added one more bike/poultry fetishist to the list. The voice at the other end of the line was an old comrade of ours, one of the proprietors of Petaluma Urban Homestead, who we know from Mr. Homegrown Revolution’s post grad school sojourn in the dull city of San Diego. In the ten years since we lost contact it turns out that our lives have taken similar paths, including the appreciation of Xtracycles and poultry.

Except that the folks at Petaluma Urban Homestead have had the brilliance of exploring the world of ducks in addition to chickens. The Petalumans correctly describe the garden destroying power of chickens as “like having teenagers around”. As much as we enjoy our chickens we can confirm this. On their blog the Petalumans describe some of the virtues of the less destructive duck:

Bill Mollison once said something like, “You don’t have a snail problem. You have a dearth of ducks”. Well, he’s certainly correct. Our neighbors are now bringing us their snails and asking if they can borrow our ducks for a day. Even the kids at the local elementary school garden collect snails for us. It’s a family event to come through our back gate and feed the ducks what they’ve gathered.

We’ve added the Petalumans to our comrade list to the right so that you can keep up with their activities, which include a recent honey harvest from their backyard beehive. In the meantime we’ll get around to describing our theories of chicken housing and the construction of what we call “Chicken Guantanamo” soon.
