“Essential water” is a project to reduce the consumption of water used for washing clothes, based on the use of excess humidity from the washed clothes and the laundry room environment, as well as the recycling of the grey water used in the washing process. To do this, it integrates a double system: on the one hand, the creation of new water from an atmospheric water generator, and on the other hand, a system for filtering the water used in the washing process. The device has a water tank holding up to 75 litres of water, which would provide enough water for several loads of a washing machine.

The project contributes to achieving the following Sustainable Development Goals: SDG 6 (Clean Water and Sanitation), SDG 11 (Sustainable Cities and Communities) and SDG 13 (Climate Action).
