Newater Delhi


System for recycling wastewater in cities

Inspired by the severe water scarcity crises facing 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.

    After completing a bachelor’s degree in spatial design and a first internship in Manila in the Philippines, Marie went to India to join the Transcultural Design Master’s program. She finished her course with an internship in Shanghai, a city she considers to be a veritable laboratory for design research and experimentation. For Marie, it is vital to address the social aspects of environmental issues today. She draws her inspiration from nature’s organic shapes as well as from innovation and pared-down contemporary style. Today, Marie is working as an interior designer at Austerveil Architecture & Design in Shanghai, an agency with a strong focus on the environmental impact of its projects.more
