We heat our home during the colder months using a 7KW wood burner. All our wood is from our, or our friends farms.
Our camping shower is heated using a back pipe in the sun. Our home water heating uses an anaerobic compost pile to generate 60C+ temperatures. We are currently in the experimentation phase with this and have had some early successes using horse stable bedding as the composting substrate.
We have two bathtubs making worm compost 24/7. We use our humanure as a food base for the worms, and add green material when we have a surplus (after vegetable harvests and weeding for example)
Our chicken/ducks coops have an open base so all their night time droppings land on a pile of dry straw or sawdust which is periodically composted. The poultry runs are deep mulched with straw. Every month or two we clear the runs and make a large compost using the scratched up straw mixed with the bird poo.
Importing Organic Matter
In order to make compost on a small farm scale we need large amounts of organic matter. We import horse manure/stable bedding from a friends stables, wood chip and sawdust, straw and olive leaves from the local olive press. Many of these are waste products at other establishments, which we turn in to resources at our farm.
Our toilets have a single bucket with no separation of liquid and solid. Fine sawdust is added as a carbon material. We collect our sawdust from a local sawmill. Sometimes we will leave the contents in its own pile to compost for a a few months before adding to fruit trees and sometimes we will put the contents directly into the worm composter as a base for the worms.
We heat our food with a gas hob. In the future we hope to produce our own biogas. We also have an earthen oven which is used on occasion.
We collect our drinking water every week or two from a local spring. We will soon be building a large rainwater tank to collect water from the roof of our house for drinking and possibly home use. Our first aim is to stop taking well water for home use and a future goal is to stop taking it for irrigation too. Irrigation however will be a challenge as we need hundreds of thousands of litres a year if we are to irrigate a commercial market garden.
The water for our showers is from our well. We currently treat it with chlorine as the water contains E-coli. As mentioned above we may be able to use rainwater collected from various roofs to use for drinking water as well as general home water.
Grey Water Treatment
Our shower grey water runs straight in to a mulch pit growing mint and various other plants. Mint grows incredibly well in the grey water systems. Our home grey water runs through a compost/worm filter first and then on to a wicking bed containing mint and other plants. The remaining water is drained to productive trees and plants.
All our home electricity is supplied by a 1200W 24v solar system. For moving water we have a 150W solar pump.
