Water is a crucial element for everyone. We use it to wash ourselves and our clothes, to do the dishes and flush our toilets. But how often do we think about what happens to all the water we pollute? Within Nomad City we want to take back the responsibility of the water we use. Therefore we installed a helophyte filter system. Within this tank we planted a group of plants that are known for their ability to absorb waste materials from water as their nutrients. This way we can filter the grey water from our kitchen sink and shower before we let it run back into the natural environment. For more info on how to build this system, check out or Nomad City Database.
