Rainwater harvesting CSR activities

A multi-year CSR partnership with ATC Tyres (through United Way, Mumbai), TATA Power, Krishna Mines, Cheran Spinning Mills and Bhuvaneshwari Cotton Mills — rejuvenating water bodies and recharging groundwater in the water-stressed Manur Block of Tirunelveli and parts of Karur District.

The project

What this project set out to do

Project mission

High-impact rainwater harvesting projects partnering with leading corporate entities to address critical water scarcity, enhance agricultural resilience and promote sustainable livelihoods — improving water security by rejuvenating traditional water bodies, increasing groundwater recharge, and empowering communities with the knowledge and infrastructure for effective water management.

Since 2018, Coodu Trust has partnered with several leading corporate entities — ATC Tyres (through United Way, Mumbai), TATA Power, Krishna Mines, Cheran Spinning Mills and Bhuvaneshwari Cotton Mills — to deliver rainwater harvesting projects under Corporate Social Responsibility mandates. Work focused on the water-stressed Manur Block in Tirunelveli District and parts of Karur District: the ATC Tyres project began across 1,200 hectares in 2018–19 and covered 18 villages, while Cheran Spinning Mills supported work in village water bodies in Kadavur Block, Karur.

The partnerships built a full spectrum of water infrastructure: 18 traditional tanks desilted — seven each under TATA Power and Krishna Mines, four more with ATC Tyres — plus 118 recharge shafts (67 ATC Tyres, 22 TATA Power, 21 Krishna Mines, 8 under the ATC Tyres climate adaptation project), 25 baby ponds, 90 metres of trench banding and 125 rooftop rainwater harvesting systems for households.

Planting ran alongside the civil works: 41,250 trees with ATC Tyres, 5,600 with Krishna Mines and 4,460 with TATA Power — Palmyrah, mango, sapota, tamarind, lemon and other horticultural species in tank areas and on farmers' land — followed by 8,450 Palmyrah seeds along tank bunds and a further 4,250 Palmyrah and native trees on bunds in 2024–25.

The key strategy was active community participation: forming local user groups — 13 with ATC Tyres, 7 with Krishna Mines, 5 with TATA Power, and Village Natural Resource Management Committees in 2024–25 — and running extensive capacity-building programmes so that farming communities, households and livestock keepers own and sustain the created assets for the long term.

Why this work matters

The challenge on the ground — and our answer

The challenge

Silted tanks and falling groundwater

In water-stressed blocks like Manur, traditional tanks lose their storage to silt and rain runs off instead of recharging aquifers — leaving farms without reliable water.

Our response

Rebuild the recharge infrastructure

18 traditional tanks desilted, 118 recharge shafts, 25 baby ponds and 90 metres of trench banding built — and the water table rose by 5–10 feet across the project villages, letting farmers take three crops a year instead of one or two.

The challenge

Assets that fail without local ownership

Water structures built for communities — rather than with them — often fall into disuse once the project team leaves, with no local structure to maintain them.

Our response

User groups and capacity building

25 user groups formed as local management structures — 13 across 13 villages with ATC Tyres, 7 across 5 villages with Krishna Mines and 5 with TATA Power — backed by capacity-building on rainwater harvesting, agriculture and animal husbandry.

Outcomes

What the project changed

Water table rose 5–10 feet

Measurable rise in groundwater levels across all three rainwater harvesting programmes in Manur Block — with improved water security for agriculture and livestock.

25–30% cultivable area expansion

Cultivable area increased by 30% in the ATC Tyres villages and 25–30% under TATA Power and Krishna Mines, enabling three cropping cycles a year instead of one or two.

Community ownership that lasts

25 user groups and capacity-building programmes ensured long-term sustainability of assets, while afforestation drives enhanced ecosystem resilience and biodiversity.
