Discuss the Namami Gange and National Mission for Clean Ganga (NMCG) programmes and the causes of mixed results from previous schemes. What quantum leaps can help preserve the river Ganga better than incremental inputs?

Introduction: Namami Gange, the integrated flagship approved in 2014, is implemented by the National Mission for Clean Ganga, the executive arm of the National Ganga Council. It marks a decisive shift from the narrow, sectoral Ganga Action Plan to a whole-basin mission.

Programme design: An initial outlay of about Rs 20,000 crore, later raised and extended to 2026, funds sewerage networks and Sewage Treatment Plants, industrial-effluent control, river-front and river-surface cleaning, afforestation, biodiversity conservation, and the Ganga Gram public-awareness pillar in riverside villages.

Why earlier schemes gave mixed results:

• Treatment capacity chronically lagged the rising volume of sewage flowing into the river.
• Fragmented Centre-state institutions and weak coordination across the five main riparian states.
• Poor operation and maintenance of built plants, plus low cost recovery and irregular electricity supply.
• Neglect of ecological flow and of diffuse non-point pollution from farms and small towns.

Quantum leaps: hybrid-annuity contracts that pay operators for measured performance over fifteen years; a one-city-one-operator model for sewage management; mandatory online effluent monitoring backed by real penalties; treated-water reuse by thermal and industrial users; restored floodplains and notified environmental flows; and decentralised treatment in small towns rather than reliance on a few mega-plants.

Conclusion: A river-basin, outcome-linked model that funds long-term maintenance, not just one-time construction, and treats the Ganga as a living ecological system can preserve the river far better than incremental, asset-heavy spending.
