Profit or loss? Urban redesign series - Water systems

Redesigning Mumbai's Stormwater and Drainage, toward a better management system for urban areas.

Why should we restore our water system?

It's plain to see, and reported often enough that our cities are falling apart. Unsustainable, and sometimes horrific development patterns and bad architectural designs are creating a monster mess creating cities with infrastructure falling apart as quickly as they grow.

Our ecosystems continue to deteriorate at a rapid pace, and cannot support life, creating a toxic backlash to the human community.

What are the problems that we have seen?

Loss of historic wetlands
Disruption of water flows
Deterioration in water quality and toxic chemical buildup and accumulation in sealife
Vast quantities of freshwater wasted and fouled
Mangrove and beach ecosystems affected by continuous and ever growing garbage buildup
Health risks for surrounding communities, in this case the entire city

 A possible vision

Turning our nallas back into walkable or navigable streams, rivers and canals for human use, through an ecological design approach.

We propose to change our wasted and polluted spaces into productive, ecologically and economically viable areas through the framework of landscape restoration, ecodesign techniques, and sustainable development principles.

Through this work, we can bring together communities and stakeholders into an open forum, making them aware again of their impacts on the environment.
Hopefully this will lead to a nurturing and revival of citizen's relationship with their land and people.
 
What kinds of lands are we talking about?

The issues we see are systemic, and creating solutions cannot be done on a  piecemeal basis. One cannot fix one section of drain and hope the problem will be solved, just as covering street drains does not solve the problem of foul and smelly gutters. Out of sight, out of mind, but still part of reality, unfortunately.

  Thus we propose to reconnect the land to the water, and work across the matrix, on:

Stormwater drains
Public parks
Mangrove lands
Reserve mangrove forest/Beaches



Operational benefits from a redesign

Reduction in urban flooding
More walkable / navigable green spaces
Healthier downstream ecosystems/ food web security
Reduction in health risks for immediate and surrounding community
