EAUTARCIE is more than a simple technical option: it is a leap towards free-spirited open-mindedness. It expresses a political standpoint that tackles present-day consumer-society, the «all-to-the-bin» logic and its analogous «all-to-the-sewer» philosophy. It is a way out of our «throw away» society of institutionalized irresponsibility.

About the word EAUTARCIE (pronounced «Oh-Tar-See»): in French, ‘EAU' means water, ‘AUTARCIE' means AUTARKY, or a self-sufficient system independent of outside influences: EAUTARCIE, is therefore a neologism. The word was first coined by Philippe Gauthier and Manu Simon in 1997 in their film production «Eautarcie: Le civisme hors la loi» (Eautarcie: Civic Stances Outlawed), about the first set-up built along these lines.

The EAUTARCIE website's pages could easily fill a book. The Site Map – Glossary – FAQs – Downloads will help the reader find all practical information sought. But to understand the technical solutions proposed, it is best to read the chapters as you would a book. Reading individual pages out of context can instil further interrogations that are answered in other chapters. In fact, most frequently asked questions from my readers reflect a superficial reading of the website. As to sanitary engineering specialists, I can only urge them to a full reading of all pages, to avoid too hasty a judgment and faulty conclusions about the philosophy propounded on the EAUTARCIE website.

How to Become Independent of Public Water Supply and Wastewater Networks

Prospects on Keeping Climate Change in Check

The Objectives Behind EAUTARCIE

To get an overview of EAUTARCIE’s Guiding Principles, click here.

The EAUTARCIE system constitutes a set of complementary techniques for sustainable water management worldwide. When examining the various proposals contained within this website, the reader will discover that the way to keeping climate change in check inescapably involves the concomitant management of water and biomass. Ultimately, the elimination of water problems worldwide is the natural outcome of this approach. The implementation of a global water/biomass management program depends on political and economical decision-makers. The individual has very little say in the matter.

Our first goal is to provide information to those who have the power to decide of the outcome of our beautiful blue planet. With all the environmental gloom and doom that is spread around by the media, EAUTARCIE aspires to be a message of hope. Beyond the growing inventory of environmental problems, it is distressing to observe the absence of concrete solutions to our dilemma. We therefore proclaim: humanity can shift away from the present destructive course. The new path is set, but it is time to make the correct decisions, on a global scale as well as an individual level.

The practical elements within the EAUTARCIE website are intended to help individuals make the correct decisions. On the road to a sustainable world, what is wonderful with the solutions herein proposed is that they do not put in question our modern comforts, and they are simpler, more reliable and less expensive than current compulsory techniques. They also provide better health safeguards. However, they have a «major drawback»: they call in question the centralized management of systems that are controlled by monopolies, and are less profitable techniques for those industries that depend on pollution de-pollution. Furthermore, by not adopting the new path, some players are tempted to control water as a commodity and a means of increasing their power. It should be noted that by resorting to corrective «repair» techniques that are in fact destructive, current legislation worldwide is the key obstacle to extending preventive problem-solving techniques that go to the root of the problem. Indeed, most techniques propounded on the EAUTARCIE website are shrugged off as marginal or even prohibited.

It is urgent to stop such techniques as the massive destruction of the biomass contained in our urban wastewater, the valorization of biomass for energy production (wood pellets, biomethane, biofuels, etc.) and speculation-based agricultural production.

The techniques proposed herein, like rainwater harvesting for whole-house reuse (PLUVALOR system), can be set-up in any home, whereas others, like grey water treatment (TRAISELECT system) are appropriate for dwellings that have a garden (or "backyard") covering at least 100 m². Nevertheless, the EAUTARCIE concepts are even transposable to urban areas. In a future we hope is not too far off, entire city neighbourhoods will be built as per the EAUTARCIE system. It can easily be shown that by integrating sustainable water management, such neighbourhoods will cease to pollute water and will have little impact on our water reserves. Up to now, the few attempts that have been made in this direction by individuals and groups of individuals have been categorically refused by regulating authorities. Even for small-scale experimental projects.

The techniques presented herein are the result of 20 years of scientific university research, field-tested in Europe and Africa. This website's purpose is to inform, without any commercial pretence.

What You Can Expect from EAUTARCIE

If your home's horizontal roof area exceeds 30 to 40 m² per occupant, your expectations can be as follows:

To become independent of the public water supply network.

To obtain naturally mild freshwater for all domestic uses, at a cost varying between 0,50 and 1,00 € per cubic meter (1 cubic meter=1000 litres), when considering amortization of the initial set-up.

To obtain drinking water which's quality is comparable to the best bottled mineral water sold on the market, at a cost between 0,02 and 0,08 € a litre.

To treat your household grey water in your garden (or backyard) with a small underground system. The quality of the treated water that is then infiltrated into the soil or discharged into a waterway will be close to that of potable water, and very often of equal quality.

To obtain high-quality compost to regenerate the soil of your garden. This compost will absorb all your garden and kitchen waste, thus reducing the volume of your household garbage for municipal pick-up, by 40%.

To save between 500 and 2 500 € on your household wastewater system, if you live in a neighbourhood where single-home on-site sewage facilities are the standard (e.g. septic tank and leach field).

To have a clear conscience with respect to future generations.

By applying EAUTARCIE, your home will have little impact on the site : no water will be taken up from water reserves and no water will be polluted by the home. The water that falls on your roof will be restored to the soil in a state that is close to that of potable water. Finally, you will be restoring the nitrogen and phosphorus from your dejecta back into the food production cycle.
