YAMUNA RIVER PROJECT | SUPPLEMENTARY DRAIN, DELHI, INDIA
Design research hypothesis: Is it possible to recover the marsh through integrating it with the city and the hard urban infrastructures? (as opposed to ‘protecting and isolating it’)

MARSH IN DANGER
“Water in Delhi is an indicator of the last 150 years
ONE AND ONLY NATURAL MARSH PIECE IN DELHI CITY
of urban development , call for urgent recovery o f the Yamuna and its tributaries now.”
THREE MOST IMPORTANT NATURAL ECOSYSTEM 1. Yamuna River -

- Support floodplain ecosystem - Government cleaning funding $500,000,000

Take the lessons from standard sewage treatement process, design constructed wetland in different ways to meet the treatment requirements. Abandoned STP is designed into a public park that visitors could learn the treating process. Built-in constructed wetland gives second birth to those abandoned STP facilities by letting them do natural treatment work today. One serious of constructed wetland, in a more rural condition, are designed for future STP and is diverting treated effluent to supplementary drain. Public park are inserted along for drain access and future development.

INTERNVENTION 2: Loop to treat MARSH ECOSYSTEM REINTRODUCED
STPE 2 : REDISTRIBUTION
LOOP: infrastructure x ecological restoration After receiving steady clean water supply. Key plant species are introduced to help the restoration of marsh ecosystem. Not only riching the plant community from different stratas, but also creating sanctuaries for birds and wildlife, especially for migratory visitor. The elevated skywalk offers different observation points and a path that separates visitors from the ground level in order to minimize disturbance of the newly grown forest. Bird watching towers are inserted along the path for research purpose.

STPE 3 : RECONNECTION
ACCESS: stormwater management x public space New marsh edge will provide multi-functional public space with treated rainwater. Rainwater will be diverted to the infiltration pond and treated there. After treatment, clean effluent will be reused as irrigation water on site (for kitchen garden) for education purpose. Various space are provided as playground, outdoor education for children, plaza for public gathering during traditional festival. People are able to access marsh through wooden bridge or even cross marsh through elevated skywalks in woods.
