Inspired by the severe water scarcity experienced by numerous Indian cities, Newater Delhi proposes a new strategy to recycle water from the city’s buildings using micro-algae.
The system uses large cellular trays, installed on a bamboo structure that attaches to the building. These trays are home to micro-algae that feed on the waste water collected and distributed by water tanks on the building’s roof, removing harmful bacteria. Working with the sunlight, the micro-algae purifies the water, enabling its re-use, while also providing thermal insulation. The Newater Delhi recovery and irrigation process offers a low technology solution that increases the efficiency of water preservation and enables its sustainable consumption.
