-FINALIST of Waterless World Competition

 

The guiding principle of the ‘sponge-city’ is the focus of the design in the informal settlement ‘Sangam Vihar’ in New Delhi. The idea is to store water during the monsoon season and then slowly use it during the other seasons. The informally growing character of the settlement and the limited possibilities of its inhabitants to take additional economic risks require measures that can be constantly rebuilt. We therefore propose a modular system of rentable scaffolding that can be rented, expanded and deconstructed over time. The creation of a new roof area for the (rented) solar panels allows rainwater to be specifically drained and collected in water barrels. Dry toilets form a key principle for dealing with human excreta in the settlement: they can be brought to central collection points in previous building gaps in exchange for state-subsidised food vouchers. The material is temporarily stored for a maximum of one day until it is collected and taken to the surrounding agriculture as fertiliser. Their products are in turn taken to a central market in the neighbourhood, where they can be bought at a reduced price in exchange for the aforementioned food vouchers.
