In a landmark initiative aimed at transforming environmental challenges into community assets, the Central Mine Planning and Design Institute (CMPDI), a subsidiary of Coal India Limited (CIL), has mapped 437 vacant coal mines—both active and closed—for their water storage potential. This project was undertaken following the directions of the Prime Minister, with the goal of repurposing abandoned and underutilized coal mines into viable water sources.
According to the CMPDI study, these identified mines have the capacity to provide approximately 2,076 million kilolitres (or 207.6 crore kilolitres) of additional water annually.
Water Fit for Domestic and Agricultural Use After Moderate Treatment
Unlike mine water in many Western countries, which is typically acidic and unusable without extensive treatment, CMPDI’s analysis found that water from most Indian coal mines is suitable for domestic, industrial, and agricultural use with only moderate treatment.
Water quality tests were conducted based on standards set by the Central Pollution Control Board (CPCB) and BIS:10500 guidelines. In some regions, the treated mine water is clean enough to be used for bottled drinking water, offering new livelihood opportunities for self-help groups (SHGs).
22 Pilot Projects Launched in Six States
CMPDI has identified 22 pilot projects across six states, including Jharkhand, where treated mine water will be utilised for:
- Irrigation
- Community water supply
- Low-cost bottled water production
These projects aim to directly contribute to India’s commitments under the United Nations Sustainable Development Goals (SDGs), particularly those focused on clean water, sanitation, and climate action.
Coal Ministry Backs Expansion of the Initiative
During a recent review meeting, the Secretary of the Ministry of Coal praised CMPDI’s initiative and directed all coal companies to formulate concrete plans for mine water treatment and reuse.
“The potential of mine water as a community resource is immense. This initiative not only reduces environmental liabilities but also addresses local water scarcity and generates employment,” the Secretary noted.
A New Chapter in Sustainable Mining
This innovative approach is being hailed as a milestone for India’s coal sector, marking a shift towards sustainable and circular resource management. By turning former environmental liabilities into valuable assets, the coal industry is expected to play a pivotal role in enhancing local water security, improving community welfare, and reducing the ecological footprint of mining operations.
About CMPDI
CMPDI, a subsidiary of Coal India Limited, plays a key role in planning and designing coal mining operations in India. Recently, it identified over 400 vacant coal mines with potential for water storage, promoting sustainable water use. CMPDI also supports environmental management and resource development in the coal sector.
About Coal India
Coal India Limited, headquartered in Kolkata, operates under the administrative control of the Ministry of Coal, Government of India. The company plays a critical role in meeting India’s energy demands, and Mr. Panda’s appointment is expected to bring valuable insights from the fields of economics and journalism to its strategic deliberations.
