Water and Wastewater Management


Given Chennai’s frequent water challenges, the city is focusing on rainwater harvesting and recycling wastewater:

  • Rainwater harvesting has been made mandatory for all buildings.

  • Desalination plants and water restoration projects are being strengthened.

  • Lake rejuvenation projects, like the restoration of Adyar and Cooum rivers, help maintain water ecosystems.

Community Involvement

One of the strongest aspects of Chennai’s green movement is citizen participation.
Local groups, schools, and environmental NGOs play a big role in:

  • Beach clean-ups (like the famous Marina Beach Clean Drive)

  • Awareness campaigns on plastic reduction

  • “Zero Waste” events and eco-friendly festivals

These community-led initiatives show how small changes by individuals can make a big difference.
