RIVER REJUVENATION AND POLLUTION ABATEMENT

1. At a Glance

• River rejuvenation in India is delivered through two parallel central schemes: Namami Gange (Ganga basin) and the National River Conservation Plan (NRCP) (non-Ganga rivers), both under the Ministry of Jal Shakti, Department of Water Resources, River Development & Ganga Rejuvenation (DoWR, RD&GR) [S1][S2][S3].
• Pollution abatement hinges on Sewage Treatment Plants (STPs), river-front works, industrial effluent control and biodiversity conservation, with the Central Pollution Control Board (CPCB) acting as the data authority on Polluted River Stretches (PRS) [S1].
• Examinable because it cuts across GS-III (environment, infrastructure), GS-II (centrally sponsored schemes, federalism) and is a recurring Prelims target (scheme names, budget figures, implementing agency).

2. Why in the News

• PIB release dated 02 Feb 2026 (Ministry of Jal Shakti): under Namami Gange, 218 sewerage projects worth ₹35,698 crore with 6,610 MLD STP capacity sanctioned; 138 projects (3,977 MLD) completed [S1].
• CPCB Polluted River Stretches reports — 2018 vs 2025: improvement recorded in the main stem of river Ganga; pH and Dissolved Oxygen (DO) meet bathing-criteria norms at all monitored locations (Jan–Aug 2025 data) [S1].
• April 2026: Jal Shakti Minister C.R. Patil inaugurated the National River Research Centre at the Wildlife Institute of India (WII), Dehradun [S2 search result].

3. Background & Evolution

• 1985 — Ganga Action Plan (GAP-I) launched by PM Rajiv Gandhi; first major centrally funded river-cleaning effort.
• 1995 — National River Conservation Plan (NRCP) carved out to extend pollution-abatement work to non-Ganga rivers [S2].
• 2009 — National Ganga River Basin Authority (NGRBA) constituted; Ganga declared National River.
• 2011 — National Mission for Clean Ganga (NMCG) registered as a society.
• June 2014 — Namami Gange approved as Flagship Programme with ₹20,000 crore outlay (to March 2021) [S2].
• 2016 — NMCG notified as an Authority under the Environment (Protection) Act, 1986.
• 2019 — Ministry of Jal Shakti formed by merging water-related departments [S2].
• 2022 — Namami Gange Mission-II approved with ₹22,500 crore outlay till March 2026 [S1 search result].

4. Core Static Facts

• Nodal Ministry: Ministry of Jal Shakti → DoWR, RD&GR [S1].
• Implementing body (Ganga): National Mission for Clean Ganga (NMCG), an Authority under EPA 1986.
• Implementing body (non-Ganga): NRCD (National River Conservation Directorate).
• Monitoring agency: CPCB — manual water-quality monitoring of Ganga at 112 locations across 5 main-stem states (Uttarakhand, UP, Bihar, Jharkhand, West Bengal) [S1 search].
• Namami Gange — sanctioned projects (Feb 2026 PIB): 218 sewerage projects, ₹35,698 crore, 6,610 MLD; 138 completed at 3,977 MLD [S1].
• Namami Gange Mission-II outlay: ₹22,500 crore (till 2026) [S1 search].
• NRCP coverage: 34 rivers, 77 towns, 16 States, sanctioned cost ₹5,870.54 crore, STP capacity 2,522.03 MLD created [S2].
• Statutory base: Water (Prevention & Control of Pollution) Act, 1974; Environment (Protection) Act, 1986; River Ganga (Rejuvenation, Protection and Management) Authorities Order, 2016.
• Cost-sharing: NRCP is a Centrally Sponsored Scheme (cost shared with States); Namami Gange is a Central Sector Scheme (100% central) [S2].

5. Multi-Dimensional Analysis

Environmental - Improvement in Ganga main-stem water quality (CPCB 2018 vs 2025); DO ≥ 5 mg/L and pH 6.5–8.5 norms met for bathing criteria (Jan–Aug 2025) [S1]. - BOD remains the principal failing parameter in tributaries (Yamuna, Kali, Hindon). - Beyond sewage: afforestation, ghat development, biodiversity (Gangetic dolphin, Hilsa).

Administrative / Federal - Hybrid Annuity Model (HAM) for STPs — 40% capex on construction milestones, 60% paid over 15-year O&M to ensure performance. - States are executing agencies; One City–One Operator model adopted to fix accountability. - Coordination gaps with State Pollution Control Boards remain a bottleneck.

Legal / Constitutional - Water is in State List (Entry 17); inter-state rivers under Union List (Entry 56). - Right to clean water read into Article 21 (M.C. Mehta v. Union of India, 1988 — Ganga pollution case). - NGT has continuing mandamus over Yamuna/Ganga pollution.

Scientific / Technological - GIS-based Ganga Tracker, drone surveillance, real-time effluent monitoring (OCEMS) on Grossly Polluting Industries (GPIs). - National River Research Centre at WII for river-ecology R&D.

Economic - Sewage treatment also yields reuse water for industry/agriculture; UP's Mathura refinery sources treated water from STPs (circular-economy precedent).

8. Mains Relevance

• GS-III: Environment & pollution, conservation, infrastructure.
• GS-II: Centrally Sponsored vs Central Sector schemes; centre-state coordination.
• Syllabus heading: "Conservation, environmental pollution and degradation"; "Government policies and interventions".
• Likely stems: 1. "Despite a decade of Namami Gange, river pollution abatement in India remains uneven. Examine the structural and federal bottlenecks." (GS-III, 250 words) 2. "Discuss the role of the National Mission for Clean Ganga as a model for inter-state river basin governance." (GS-II) 3. "Evaluate the Hybrid Annuity Model for STPs as an instrument of pollution abatement in India." (GS-III)

10. Common Errors / Trap Areas

• Wrong ministry: Namami Gange is under Jal Shakti, NOT MoEFCC.
• Scheme classification: Namami Gange = Central Sector (100% central); NRCP = Centrally Sponsored.
• NMCG's legal basis: notified under EP Act 1986, not Water Act 1974.
• Year confusion: GAP = 1985, NRCP = 1995, Namami Gange = 2014, Jal Shakti Ministry = 2019.
• Coverage: NRCP excludes Ganga basin rivers; do not assume it covers all Indian rivers.
