The era in which we are living seems to leave us ever more fascinated with technology, this great human endeavor that has the power to free us from the yoke of nature or that makes human beings an extension of the creator. And yet, with water, we seem to maintain an astonishing relationship: we project on water a desire, an ideal of purity and natural virginity far removed from technical complications and other social contamination. We could be tempted to say, “Cover these impure waters so that we may not see them,” to paraphrase the famous repost of Tartuffe to Dorine. In reality, the clear, pure water that apparently arrives so naturally and drinkable in the heart of the city only comes at the cost of increasingly sophisticated and expensive technology. Water is a hairy1 object that is tightly woven into social, environmental, economic, and political complexity.
In fact, water has been invisible in our city for a long time. It is a black stain on our urban development policy, repulsed by our imaginations and our concerns as citizens. And like many other elements that we don’t want to see realistically, it risks resurfacing, like the return of the repulsed, to manifest itself ever more painfully from crisis to crisis. Which is why the headlong rush towards more technology – in the name of progress – resolves some questions while posing more, and never exhausts the need to render the management of this precious resource more visible and more conscious, therefore more collective, more common... Let’s say it another way: technology and society can only exist in a complex combination of integrated interdependence. Water, like climate, is a fact of nature, but also a social, economic and political fact that merits better understanding if we wish to keep it as a common good.»

Through the development of the water point, our aims moved from creating just a meeting place, to test how far we could go in purifying urban water or even making it fit for human consumption. We started investigating drinking water standards (according to EU, WHO, ISO guidelines), probes, filter systems and measuring devices and forged alliances with chemist and DIY water-engineers.»
As part of EauPropre I ProperWater the low tech water purification system would be connected to the rain harvesting pavilion. This led to some technical specification: the system had to be mobile and compact, had to work with changing flow rates, and be able to filter rain-water at the simple request of passers-by/visitors, without having to make them wait too long.
Therefore (and much to our regret) the following plans had to be abandoned. These methods were too slow, too uncertain or required electricity or constant care.
We decided to list them here below, just for the fun of it:»
The Proper Water Filter system
The filter set-up that survived drinking quality tests is a combination of pre-filtration already taking place in the storage tank, and a collection of four micro-filtration (membranes with pores of 5 and 0.1µm) and ultra-filtration (membranes with pores between 0.1 and 0.01µm) filter heads that last for about six months.»
