During our trip to Nuevo Ayacucho, Peru in October 2021, we were able to gain valuable insights. With proximity to the sea and great water scarcity, this place reflects exactly our described problem. To support these people, we are now using our knowledge of market conditions to find the best solution for our local partners in an innovation phase. The goal is to install a central water purification system on site to supply the almost 2000 people with clean water. In our current work, we think openly and honestly about the possibility of whether and how such a project could be useful or not.
