The construction of the student-house PAKASHKA-SACHA offered several challenges. The access-road construction in this very hilly terrain was the first. The location of the house was determined after several camping stops in the forest. Water connection was another hurdle. There is water on the property. However, some of it is difficult to access and therefore costly to unite. Therefore, we decided to connect to the local water network. To cope with the unreliability of the water supply, several water reserve tanks were built to provide us with a bridging reserve of over 5000 liters.

Since the center PAKASHKA-SACHA is an educational project, with the goal of protecting our environment, the ecological aspect was of course taken into account in all areas. This in the construction method, choice of materials etc.. And of course also in the sewage disposal. 

Ecuador is almost like Switzerland a water castle. A privileged starting position that is unfortunately not responsibly appreciated and protected here in Ecuador. Water pollution is an everyday problem here. Most rivers are completely polluted. The concept of sewage treatment plants is here a rather foreign word. Reasons are of course finances but also unawareness of how valuable the good water is. 

Therefore we have built an autonomous water purification system. It consists of 7 tanks. Sludge tank, fermentation tank, stone filter, gravel filter, sand filter, carbon filter and plant filter. 

The final result is clean, pure water that can be fed back into our streams. Since the whole plant is built on a slope, the water flows independently and no energy sources for water pumps etc. are necessary. Economical water consumption and the use of organically degradable cleaning agents are additional measures to protect our environment.
