Water is a vital substance for survival and health. Our own bodies are made up of 55 percent water, while 70 percent of the earth’s surface is covered by water. Out of the 70 percent of Earth’s entire water, only 3 percent of that is freshwater. Making up that 3 percent there is less than 0.3 percent of freshwater which is easily accessible to us. In perspective, that 0.3 percent is spread over 195 countries, leaving 2.3 billion people to suffer from a lack of access to clean drinking water (UN). Without action these statistics will only increase by 2050 when global demand for freshwater is expected to be one-third greater than it is now. Finding alternatives to current water filtration methods will be at the forefront of architecture and design for the predicted water-stressed countries.

 Drip.Drop positions itself in the interstice of localizing water filtration in our communities. With this body of research, we showcase the future of bio-based water treatment solutions through the use of Chitosan- the second most abundant biopolymer on the planet. Drip.Drop set out to examine and imagine a system able to separate pollutants from our effluent water, and to lessen the impact of the waste we inject in our waterways.
