Rise Chennai
Within Chennai city the project proposal from Deltares included the following components:
- Muthucharam Mambalam
The current Mambalam drain is the last physical remnant of a former reservoir tank, and one of the few remaining traces of the city's original tank waterscape within the city's centre. By turning it from a stagnant, seasonal, drain into a flowing, perennial, canal, we believe it carries the potential to become a thriving and central part of the city. The project we propose for the Mambalam canal aims to improve the resilience of Chennai’s water network by opening up and redesigning the canal profile, its bridges and surrounding urban developments; mitigating flood risk, improving water quality, groundwater recharge, waste management and reducing water use.
- Neithal Muttukadu
The Muttukadu basin is a fast-developing area on Chennai’s southern edge. The project aims at reconnecting fishery-based livelihoods with economic opportunities tied to the revitalization of green and blue infrastructures. Starting with the degraded forest lands further inland, and building on the presence of erys (water tanks) in the perimeter of the business area nearby (SIPCOT, a Specialized Economic Zone), the project introduces water harvesting measures in order to close the water cycle locally. This revitalized waterscape then acts as a catalyst to clean up the canal, re-naturalize its banks, restore backwater sloughs, integrate decentralized wastewater treatment, and ultimately create a new vital ecology based on ecotourism that links the basin’s mouth back to the forest lands on higher ground. Nature-based sand nourishments protect the coast near the basin’s mouth and that of businesses, residents and ecologies inside.
