Solborg: A Camphill “Ecovillage”

Solborg is a Camphill Village located in southern Norway. Camphill was established in 1940 and from then until now has constructed "ecovillage style" communities throughout the world with a special emphasis on allowing residents with disabilities. Although not officially recognized by GEN as an ecovillage, it still reflects similar traits that make up the traditional composition of them. They believe society marginalizes disabled citizens and believe living at Camphill eneables them a chance to be productive and self sufficient.


In terms of waste, water and sewage Solborg carries out a few different attributes to ensure conservative, sustainable, and low impact usage of its resources. Waste for the most part is composted and later used for nutritious soil. They use horse to transport wastes to mitigate carbon emissions from motorized vehicles. Recycling is often done as well. I would assume they are connected to the local municipal services, but am unclear.


Sewage is typically treated with "ponds, reedbeds and "Flow Form" water cascades. There are many types of Flowforms, "but the central concept is that it is a vessel which brings streaming water into a flow pattern similar to that of liquid in the heart. See Picture.

Ecovillage of the Week I: Ithaca (EVI) - Recycling, Water, Waste, Sewage

Recycling, aside from their rigor of reusing, is done simultaneously with day-to-day activities. Carts full of metals, glass, compost, paper, plastic and trash are collected. It is often times moved in one trip, revealing EVI's efforts of re-usage and minimalistic consumption. Anyhow composting is successfully practiced with brown matter being put over green. When it heats up it turns to rich, odorless humus. This can be used later as nutrients for crops.

There is a common dumpster where 160 of the residents deposit their trash in a 108-cubic-foot dumpster. This is a quarter of what the typical U.S. housing development generates per week. For the recyclables, there is a shed that has bins for each item. They are collected by the local Municipal service. It is diversely successful. Lastly there is a "reuse room" where residents can donate clothing, shoes, toys and other goods. It's all so well planned!

Sewage and water at Ithaca, like anywhere else, are of utmost importance. Water is perceived as a dire necessity and conservation is extremely crucial. Water use is limited daily, while many residents have composting toilets or toilets that use minimal water in comparison to conventional toilets. Plants that are grown there are intended to use little water, while the watering of them primarily occurs in the evening, to inhibit rapid evaporation. Rainwater is avidly collected, where gutters transfer it to the pond or rain barrels collect it. It is also transferred to an underground cistern, to be drawn from for later usage. It's used for watering plants and quenching the thirst of animals.

Sewage treatment is still linked to the local municipalities system mostly because an alternative treatment system is out of EVI's current price range. They would like to see a "Living Machine" implemented however it may be pricey so they think a wetlands or reed bed system may be more likely. In the meantime, houses are equipped with dual piping systems that separate gray water from black water. The next step is to build a filtration system to cleanse the gray water.

It's Alive! The Living Machine at Findhorn Ecovillage & Recycling

Findhorn uses the Living Machine. The machine treats sewage water from the 300 residents living there. In addition to that, it serves as a brilliant example for many students and visitors to observe and study. Many can enjoy seeing the creative processes in action that make the Living Machine possible.

Findhorn currently uses the machine to undergo Phase I water treatment. They plan to install a Phase II treatment system in the near future to get off the "water grid" or mains they use now. This system will reuse the water for all purposes and distribute it accordingly. The final goal is to someday be completely self sufficient with their water resources.

As for recycling, Findhorn has a rather extensive system. They recycle paper, glass, batteries, metal and even have a clothing drive. They do not have plastic listed as being recycled, however the document may be a bit outdated. It is unclear what they do about non recyclable items, but I assume they are connected to the Findhorn's municipal trash service.

The Living Machine

The Living Machine; What exactly is it? The Living Machine have been defined as a "decentralized waste water treatment system that mimics processes found in wetland environments" and provides tertiary sewage treatment to allow dirty water to be used for irrigation, bathing and toilets. It is a remarkably innovative technology that seeks to lessen the usage of water as well as the energy put into water treatment. It breaks away from centralized sewage treatment by using natural, biological principles to treat water.

The machine itself is backed by mechanical operations and computer systems, which allow a self regulating pseudo-environment. The machine works in succession. First a series of tanks are meticulously arranged by design. Each tank "contains an ecosystem built up with materials gathered from the wild or other Living Machines" (Bang 165). The components of the ecosystem consist of microorganisms, invertebrates, fish, plankton, shrubs, flowers and mollusks. All of them provide a critical role in the overall purification process of the water treatment.

The machine is responsible for organizing and developing its own ecosystem. Then each organism is carefully assigned its tank or specific area, depending upon which biological function it will perform and carry out. The organisms literally "live off pollutants" and as the sewage enters each tank, it gradually becomes cleaner and cleaner until the end (Bang 167).

The end is when the organisms known as the "scrubbers" process and clean the water one last time to prepare it for irrigation and sometimes drinking. Living Machines can process anywhere from 2,500 - 200,000 gallons of water! It also conserves water. A zoo in the Netherlands cut its water production by 84% (Worrell 3). This helped to lower water bills and increase revenue for separate usages.

The Living Machine is a highly researched, relatively new approach towards sewage treatment, but it's popularity and development are increasing. Not only is it a more environmentally friendly approach to confronting the impediment of sewage, but it is aesthetically appealing to people of all ages. In fact it may be hard to tell you are in one! Only time will reveal the succession of this spawning, technologically innovative achievement. More posts to come!
