Focus on water restoration in Chengalpattu
Mission Blue-Green Chengalpattu: The Chengalpattu district in Tamil Nadu is now leading a significant environmental mission named Mission Blue-Green Chengalpattu. This initiative targets the rejuvenation of over 200 minor irrigation tanks out of the 500 existing in the region.
The District Rural Development Agency (DRDA) is spearheading this mission, aiming to improve local water infrastructure and prepare for seasonal rainfall.
Community and NGO collaboration
The DRDA has extended its support to voluntary organisations for reviving 388 more tanks. This collaborative effort is expected to create a wider ecological impact by involving non-governmental stakeholders in tank restoration work.
A key partner in this mission is the Environmentalist Foundation of India (EFI), which has taken responsibility for restoring 100 water tanks using eco-friendly methods.
Sustainable water management techniques
The restoration approach by EFI includes the root-zone plant filtration method. This eco-technique uses aquatic plants to treat wastewater and promote groundwater recharge, ensuring a long-term water conservation impact.
This method does not rely on chemical-based treatments, making it cost-effective, sustainable, and environmentally safe.
Static GK fact: Root-zone filtration is also called constructed wetland treatment and is used widely in Germany, Sweden, and India for natural water purification.
Timely action before northeast monsoon
With the northeast monsoon approaching, the DRDA is aiming to complete most of the restoration work by early October 2025. The idea is to ensure that these tanks can capture and store rainwater, reduce flooding, and recharge the aquifers.
This timeline is critical, as Tamil Nadu receives the majority of its rainfall between October and December, making tank readiness a crucial priority.
Static GK fact: Tamil Nadu is the only major state in India that is monsoon-dependent primarily on the northeast monsoon, unlike most other states that rely on the southwest monsoon.
Long-term benefits for agriculture and ecology
Once restored, these tanks are expected to increase local water availability for agriculture, improve groundwater levels, and provide habitats for birds and aquatic species. This aligns with broader state goals of climate resilience and sustainable rural development.
Static GK Tip: Minor irrigation tanks have been a traditional water management system in South India for centuries, especially in Tamil Nadu, Karnataka, and Andhra Pradesh.
