Overview
Effluent processing all over the world requires large amounts of energy and/or chemicals to treat the waste water, or the waste water is improperly filtered before being returned to the environment. There are a number of solutions to lessen the waste water load while at the same time producing a net benefit. Systems that include the collection of urine to be used as fertilizer and methane digesters that create fuel from feces [see 'Biogas' section at bottom of the just-linked article] are a couple of such solutions. Another solution — constructed wetland filtration systems for homes, communities, and industrial sectors — are efficient in both processing ability and energy requirements.
These artificial wetlands provide a near zero energy input way to treat local effluent with no negative side effects. The process is free of both chemicals and odours, provides habitat for wildlife, increases the diversity and aesthetics of any site, and, depending on the toxicity of the inflowing effluent, can potentially create a yield, such as fodder for livestock.

Just outside of Arusha, Tanzania, is ‘Kesho Leo’– a sustainable home for vulnerable women and children operated by FoodWaterShelter. The principles of permaculture underpin the daily lives of the Kesho Leo residents. It is currently the home of seven families, each headed by a Tanzanian mama who cares for up to five children, including orphans. In addition to the daily essentials, Kesho Leo provides the many other aspects that a ‘home’ needs; access to family and social support, access to education and health, and very importantly – access to community.
Permaculture meeting the needs of the Kesho Leo residents
Revolving around the community and education aspects of Kesho Leo are the permaculture systems that strive to provide all of the food, water and energy needs of the residents. Basic needs of water, sanitation and power are provided through rainwater harvesting, innovative batch compost toilet systems, and solar power.
Comments (7)Permaculture Resiliency Project with the San Bushmen in the Kalahari Vergenoeg, Namibia

In a land of contrast, mystery and years of imperialism, a small village of over 300 people on the edge of the Kalahari in Namibia germinated a new permaculture resiliency project in January of 2012. In talking with the headman of the village, he shared that their people, the San Bushmen, have lived in harmony with the land as hunter gatherers for eons. They are often cited as the first peoples of Africa and very likely all of humanity may have descended from their ranks many millennia ago.
The village elder sadly shared that colonialism has destroyed the San migratory way of life — a hunter gatherer tradition that was sustainable for thousands of years. He told us that they were no longer allowed to roam freely and trophy hunters destroyed the vast herds of game that formed their principal supply of food. Both Black and White farmers alike built up huge herds of cattle that destroyed the ecology of the Kalahari and subsequently the foods that had been their staple diet. They soon found they had to work for the farmers to be able to feed their families and hence a cycle of poverty and separation from their cultural roots ensued.

— the remnants of a now defunct railway.
Alternately barren and spectacular, the southwest United States has piqued the imagination of Americans and people across the world for generations. The site of gold rushes, Native American homelands, and a culture of lawlessness that has yet to fade completely, much of the land was degraded and destroyed long before Hollywood discovered how to cash in on retelling stories from its checkered past. Films may glorify the breadth and scope of the iconic terrain, but the essence and character of the Southwest ecology has been drastically altered; it little resembles what it once was.
Comments (6)Urine: Closing the NPK Loop
Conservation, Rehabilitation, Waste Systems & Recycling, Waste Water — by Mark Feineigle November 27, 2011
The Stockholm Environment Institute conducted experiments and collected data that shows the usefulness of a resource every one of us has access to — urine. When utilized as a fertilizer, urine can provide an alternative to chemical fertilizers. The impacts ripple far beyond the nutrient value of the urine; in developing regions, diverting a urine waste stream to fertilizer has a significant economic value. These benefits can easily be recognized at the individual level, and scale all the way up to industrial operations.
Jordan Valley Permaculture Project Update: Post IPC Happenings

An aerial view of the site
Although the landscape here could be seen as a model for scarcity, what there is an abundance of is rocks. The baked dusty earth barely passes for soil and during the summer there isn’t rain here for over six months. With valuable agricultural resources seemingly at a minimum, rocks can be incredibly valuable in the design of a sustainable human settlement. In the case of the Permaculture Research Institute of Jordan’s site (PRIJ), rocks have formed the main building blocks of the swales that form the back bones of this small farm. They surround the heavily mulched planting pits for the many varieties of trees here and they also can be used for another useful function which litres of my sweat has been testament to! They make up the substrate of the grey water system into which reeds are planted that feed on the water flowing through from the sinks and showers in the washing block.

In northern Jordan during the summer of 2009, I was on a mission to document a modern-day Roman-era cistern resurgence. I met with Engineer and Permaculture Project Manager Sameeh Al-Nuimat at the Care International office outside Amman. He was great. He has rural hardworking roots, loves native plants and traditional ways, is very enthusiastic and knowledgeable about whole-system design, and decided we’d begin the day by having an Arabic breakfast with everyone in the office. We all grouped around a very small, low table piled high with hummus, pita, olives, falafel etc, and ate with our hands. What a wonderful way to bring everyone together as the day begins!

Roving, roving. I’m now staying in Central Tokyo, at my usual home with the Ota family.
This morning I reached for the broom, I got a surprise. Professor Ota came running out "No No!"
He bent down, fiddled with something on the floor, and out it sprang — the floor-sweeping robot.

Editor’s Note: As many of you will have noticed, Alex has been making some great practical updates on the work going on at the Strawberry Fields Eco-Lodge. The following article is another good example. I thought I’d mention that if you want to soak in some excellent experience at this site, Steve Cran will be leading a great course beginning July 1, 2011 that you might want to attend if you can.
The heat chimney for the solar fridge
The solar fridge is a new system which we have now managed to get set up after months of pondering, trying, adjusting, tweaking and trying again. We think we have finally got it kicking and pretty well integrated into the other functions of the kitchen area, so we can demonstrate permaculture principals with it pretty nicely.
The system is based on an old design for desert/dry-land cool storages which makes use of a heat chimney to create an up-draft which then sucks cool air in to the storage chamber from below. This air may pass through a long tunnel in its way to the storage chamber and hence be cooled by the ground on the way to the chamber. In order to enhance the cooling of the air on the way to the chamber, if possible, water, by evaporating will take in thermal energy, causing the temperature of the air to fall further. The main logistical issue to deal with, as usual, in building the system, was getting the theory to work in practice using available materials. Most of the construction work on this project was done by one of our long term volunteers, Duncan Colquin from Herefordshire, England, so a big thanks to him.

“What’s that smell?” asks Chris.
“I don’t know. It’s really familiar. It smells like… cat food,” I reply.
“It smells like shit,” he says.

Editor’s Note: This article was written in mid-December, when Queensland’s rains were nothing like that witnessed of late, and which have caused the catastrophic flooding in many towns and cities across the state. I mention this to ensure people realise Nicola was not being insensitive with timing of a Queensland- and water-based article. Our thoughts go out to all who have suffered in the recent deluges.
Pit-falls, projects and laughs from our Permaculture journey
If women knew diggers looked this good I think swales would pop up like weeds
around the globe. Gee whiz. Beats a four-tonne excavator in my books
– even if it had a swivel bucket.
Chris woke up the other day and declared, “I think I can dig those swales by hand.”
“Super,” I said, “go for it!”
Comments (13)Compost Power Hot Shower Report, Ethiopia
Aid Projects, Commercial Farm Projects, Community Projects, Compost, Conservation, Demonstration Sites, Education Centres, Energy Systems, Rehabilitation, Waste Systems & Recycling, Waste Water, Water Harvesting — by Alex McCausland December 18, 2010
We recently submitted a short report on our hot-fast-composting system, which gave some detail on the theory and practice of producing compost in as short a time as 21 days. But Permaculture principals tell us that we should always be looking to yield as many useful products and functions from any process or element as possible and it is obvious that one bi-product of hot-composting is heat. If you get it really right, a heap should reach 80°C, which is literally too hot to touch. Feeling is believing. Once we were getting to that stage with our compost competency I began pondering how we could effectively catch and store some of that heat so that it can be used for a hot shower.
I finally realised that lots of mucking about with coils and heat exchange loops, lagging and insulation etc. could be avoided if we simply have the hot water tank inside the compost heap. Jean Pain, the old French Roi de Compost did something like this in his place, but took it a lot further, even to the point of having a biogas digester inside a cooling jacket inside a giant compost heap. He was able to heat his house and get compost and biogas all out of the one system. Ours is simpler, but the good thing about that is that you don’t have to be a practical genius to do it.

Permaculture is a connecting system between disciplines and elements in a matrix of design, and swales are a mainframe element. The efficiency of swales is that they can interrupt water surface flow high in a landscape where it is then infiltrated relatively quickly, on contour, and moves incredibly slowly through the landscape soil and subsoil profiles. This becomes a great advantage to the potential productivity of any property, especially a property that is designed to be diverse and interactive with many ecosystem elements. When you design a property this way, a mainframe approach as a consultant designer is:
