Building an eco-friendly campsite

In the following article, we’ll walk you through the building process for our eco-friendly campsite. We have completed two super comfy and easy-to-service compost toilets aka “the temple of poo”, two “yin-yang” shaped outdoor showers, a spacious washing station, and a social “chill-out space\”. It is eco-friendly because every drop of water is being put back into the cycle and re-used. It all turned out quite as we envisioned it and – even after a year – we’re still very happy with the outcome. When we decided to organize the “natural building workshop” in September 2020 we knew that we had a few weeks of hard work ahead of us to build a comfortable camping area to accommodate the needs of 12-15 students. It was quite a challenge, having to build all that within the hot month of August! And we had to start from scratch: There were only olive trees, a small meadow, and a ruin. But with the help of our volunteers, especially René, Markus, and Nina, we started to transform the area quickly into something else. First, we installed a small outdoor carpentry from where we’d build all the components for the dry toilets, the showers, and the washing station. Compost toilets aka “Temple of Poo” Our first priority for the compost toilets was durability and comfort. We wanted to create a structure that would last over time and could comfortably accommodate two people at the same time (in different compartments, of course 🙂 ). Also, it should be easy to service and clean in an efficient manner. The location we chose for the compost toilet would have to contribute to this latest aspect. We found a perfect spot that was close enough to the tent space and offered two different altitude levels. The reason for building the structure across two levels is that on the upper level you’ll have convenient access to the toilet spaces while on the lower level you’ll get easy access to the maintenance area with all the bins and containers. This way, comfortable usage is guaranteed for both the visitors of the toilets and the maintenance crew (us 🙂 ) to do the weekly cleaning routine. As soon as the site was chosen, we started with the foundations for the main pillars. In this case, we used a cement / gravel mix mainly because our focus was on durability and also because there is a high risk of erosion around a terraced ground that consists mainly of sandy soil. After the foundations had dried, we started constructing the wooden structure and raised the nine main pillars. Luckily, we were able to reclaim both doors and windows from a derelict house which are giving the building a unique touch. In the end, we oiled the whole wooden structure (Douglas fir) with linseed oil to protect it better from rain. One of the main reasons why the compost toilet works so well without generating unpleasant odours was the separation of liquids and solids in the toilet. A urine separator ensures that the faeces do not get the excess moisture and can therefore dry quickly without generating unpleasant odours. Another huge plus is that we can safely compost the precious “humanure” (feces) and use the urine diluted with water as a high-nitrogen liquid fertilizer for our olive trees. Yin & Yang Showers One of our first ideas was to build two intertwined outdoor showers in the shape of a drop or the Yin and Yang symbol (which can only be seen from a bird’s perspective). However, we soon realised that some modifications had to be made to the original shape to make it functional and to be able to enter and leave the “maze”. Following the permaculture principle, “Each element performs many functions” (at least three), we had set our minds to a solution that would allow us to reuse the greywater from the showers and circulate it through our land as long as possible. From a permaculture perspective, the showers are not only cleaning our guests, they also inspire us with their beauty and most importantly, they’re also helping us to irrigate our citrus trees. We knew that this would require some sort of cleaning process before we could use it for irrigation. Read on and discover the step-by-step process of constructing the showers and the reed bed to filter the water until the moment when we finally could wash the sweat and dust off of our happy faces when the showers were finished. It all started with a hole of about 4m in diameter. In the middle of the two showers, we installed a drainage system and a pipe that would transport the greywater towards the reed bed. We laid out a 4x4m pond liner (black waterproof plastic) to collect all the water from the two showers. Then we topped it up with gravel until the ground level was reached. Once the water collection system was almost done, we proceeded with the installation of posts to support the walls of the showers. Since the pond liner couldn’t be pierced or damaged, we had to construct a stand-alone wooden structure where the walls could be attached to. After the structure was finished we covered the boards with gravel. For the shower walls, we chose the local variety of cane, as it grows abundantly in this area and is available freely all year round. Each of the canes was cut to a certain height (around 2m) and a couple of holes were drilled in the ends of the cane.  Then, a wire rope was inserted through the holes to give consistency to the wall and to join cane to cane. Once the walls were done, the only thing left to do was to connect the shower heads with the pipes coming from the ground. For usability and comfort, Nina has built a small wooden bench for each of the shower compartments. Washing station & Laundry Last but not least, we also needed a place
