The Drop by Drop system is set up to mimic how nature cleans dirty water

Inspired by a Hindi saying “drop by drop, we’ll fill an ocean”, a designer is trying to solve the problem of clean water scarcity with a miniature rainforest. Inspired by natural phenomena, Royal College of Arts post-grad student Pratik Gosh built a filtration system that relies on trees to turn dirty water into something potentially potable.

The Drop by Drop system is a terrarium where leafy plants thrive inside the glass enclosure. It’s vacuum sealed so pressure can be regulated and no moisture escapes. The system works through what two Russian scientists describe as ‘biotic pumps’. This explains how the millions of trees in the Amazon contribute to the water circulation in the surrounding area. In essence, as water travels through plants and their leaves, it’s easier for it to evaporate. Consequently, the temperature layers created by the moisture further draw out more water from the plants.

The plant fibers also act as natural filters. When water travels inside the plant, it is passed through very tiny holes, leaving behind the impurities. Add that to the evaporation that turns the water into air and the result is very pure water. This biotic pump theory explains why rainforests are effective at speeding up the conversion of impure water on the surface into condensation. To use Drop by Drop, a person can just water the plants using dirty water and wait.

In this tiny version of a rainforest, condensation is captured and siphoned off drop by drop. According to the creator, it takes about 12 hours for the set-up to yield a glass of water. While this seems too slow for real world impact, the potential is in scaling the project. According to Fastcodesign, the Drop by Drop setup is actually just a proof of concept for the creator, a working prototype from which a solution begins.
