Water is life or how we came to install PAUL at OPC

First, we conducted a groundwater analysis, which showed that the main function of the water filtration system should be to exclude bacteriological contamination, as we found E. coli in the samples. In contrast, the dissolved parameters (e.g., salinity or dis-solved organic carbon) were at low levels and therefore not critical. We measured some level of arsenic in some of the samples, but on-site colorimetric tests did not confirm arsenic contamination. These advanced water analyses, conducted in our case by the Kwame Nkrumah University of Science and Technology (KNUST) water laboratory in Kumasi, help tremendously in planning water treatment systems in decentralized locations.

In the next step, we conducted technology and market research and selected the GDM technology with the PAUL as perfectly suited for the decentralized, small, and technically straightforward application we were looking for. Another challenge was the large distance between the borehole and the place of use (kitchen, garden). After discussions with some GDM experts at KNUST, we decided to install the water tower as close as possible to the kitchen to keep the freshwater pipes as short as possible. The next step was more detailed planning and procurement of all necessary materials. Once all the materials were available at the site, we discussed the whole project with a local mason who helped us build the tower. We integrated two wooden beams in the center, on which we placed the PAUL once the plastering was completed. Pipe laying and plumbing was another skill we had to learn. The straightforward approach, which produced tangible results very quickly, was very gratifying and lifted the spirit of the entire team involved in the project considerably.

Results and outlook

Since commissioning the PAUL ultrafiltration module, we have filtered about 21,000 liters of water in nine months, which corresponds to about 1,400 packs of pure water or about CHF 700. Since the cost of the entire system was about CHF 2,000, we expect to recover the investment cost for the entire system in about two years. In addition, we save costs for the transport of pure water to the ecovillage and have non - monetary side effects such as facilitation of everyday life and general improvement of hygienic conditions in the village. However, one of the main benefits is that we do not contribute to environmental pollution with plastic bags, a very important point for us as an ecovillage!!!

The surrounding community members can now conveniently get water at our tank without walking long distances to the nearest well and without having to fetch the water from the well with buckets, a significant improvement in their daily lives! This improves the harmony between our ecovillage and the surrounding families. In addition, the people who walk through the ecovillage to get to their fields can now put filtered drinking water in their jerry cans and help protect the environment!

The next upgrade to our water system will be to automate the entire system. First, we will place another tank („main distribution tank“) on top of a three-story building we are currently constructing near the borehole. This tank, as well as the borehole pump at a depth of 40 m, will be equipped with floating sensors that communicate with each other. All the water we consume at OPC then initially passes through the main distribution tank. As soon as we consume water at any consumption point on the site, the water level in the main distribution tank drops, which activates the float sensor to tell the borehole pump to pump water. In this way, we can avoid having to run to the borehole to activate the pump as soon as someone needs a larger amount of water at a specific consumption point on the site, which will once again make work and life much easier.

„Freedom is just another word for nothing left to lose“ (Janis Joplin); so, through the power of our collective virtue and merit that we have created and will create by participating in this project, may every living being find everlasting peace and happiness, and thus come to the realization that, in fact, and truth, there is nothing to lose. This is freedom. „OPC - Freeeeeeee!!!“ - this is our local shout in the streets of Busua ;)
