Five key sewerage infrastructure projects made operational for Ganga and Yamuna in Namami Gange Mission Phase II

1. At a Glance

• Namami Gange Mission-II operationalised 5 sewerage infrastructure projects in Q3 FY 2025-26 across the Ganga and Yamuna basins, taking cumulative commissioned STP capacity to 3,976 MLD and total STPs to 173 [S1][S2].
• Implemented by the National Mission for Clean Ganga (NMCG) under the Ministry of Jal Shakti; UPSC-relevant for GS-III (Environment, Pollution Abatement) and GS-II (Centrally Sponsored Schemes) [S1][S3].

2. Why in the News

• PIB release dated 09 January 2026: 5 sewerage projects commissioned in Q3 FY 2025-26 in Bihar (Patna) and Uttar Pradesh (Varanasi, Agra) under Namami Gange Phase II [S1].
• Cumulative FY 2025-26 tally rose to 9 operational projects (Q1-Q2 had added Udham Singh Nagar, Moradabad, Maheshtala, Jangipur) [S1].

3. Background & Evolution

• 2014: Namami Gange Programme launched as a flagship Central Sector Scheme with ₹20,000 cr outlay (Phase I, 2014-2021) [S3].
• 2015: NMCG registered under the Societies Registration Act 1860; later anchored under Environment (Protection) Act, 1986 via the River Ganga (Rejuvenation, Protection and Management) Authorities Order, 2016 [S3].
• 2022: Cabinet approved Namami Gange Mission-II with budget ₹22,500 crore till 2026 [S4].
• 2026 target: cumulative 7,000 MLD sewerage treatment capacity [S5].
• 218 sewerage projects worth ₹35,698 crore sanctioned for 6,610 MLD treatment capacity [S2].

4. Core Static Facts

• Parent Ministry: Ministry of Jal Shakti → Department of Water Resources, RD & GR [S1].
• Nodal agency: National Mission for Clean Ganga (NMCG) [S1].
• Statutory base: Environment (Protection) Act, 1986 + 2016 Authorities Order [S3].
• Phase II outlay: ₹22,500 crore; extended up to 31 March 2026 [S2][S4].
• Cumulative STPs operational (Jan 2026): 173 STPs / 3,976 MLD [S1][S2].
• Sanctioned: 218 STP projects / 6,610 MLD / ₹35,698 cr [S2].
• Q3 FY 2025-26 — 5 commissioned projects [S1][S2]:
• Patna Kankarbagh STP (Bihar) — capacity scaled 15 → 30 MLD (Ganga basin).
• Varanasi Assi–BHU STP (UP) — 55 MLD, sanctioned cost ₹308 crore (Ganga basin).
• Agra (UP) — 31 MLD STP under Pollution Abatement Works, Agra (Yamuna basin).
• Agra (UP) — 35 MLD STP under Pollution Abatement Works, Agra (Yamuna basin).
• Fifth project: additional component under the Ganga/Yamuna basin works in Q3 (per PIB release dated 09 Jan 2026) [S1].
• Q1-Q2 FY 2025-26: Udham Singh Nagar (Uttarakhand), Moradabad (UP), Maheshtala (WB), Jangipur (WB) [S1].

5. Multi-Dimensional Analysis

• Environmental: Reduces untreated municipal sewage discharge into Ganga/Yamuna — the largest pollution load source; advances Sustainable Development Goal 6 (Clean Water & Sanitation) [S2].
• Administrative: Uses Hybrid Annuity Model (HAM) for STPs — 40% capex on milestones, 60% as annuities tied to O&M performance over 15 years; concentrates implementation in 5 main-stem states (Uttarakhand, UP, Bihar, Jharkhand, WB) plus Delhi/Haryana for Yamuna [S2].
• Economic: ₹35,698 cr sanctioned creates urban sanitation infrastructure backbone; co-benefits to tourism (Varanasi, Agra) and groundwater recharge [S2].
• Federal: Centrally-funded but executed via state-level SPVs / Urban Local Bodies; Empowered Task Force on Ganga chaired by Union Jal Shakti Minister coordinates [S3].
• Scientific: STPs deploy SBR / MBBR tertiary treatment to meet NGT-mandated discharge norms (BOD <10 mg/L, TSS <10 mg/L) [S5].

8. Mains Relevance

• GS-III: Environment & Pollution → Conservation of Rivers; Government Budgeting in environmental missions.
• GS-II: Welfare schemes / Centrally Sponsored Schemes; Federal coordination.
• Probable stems:
• "Critically examine the progress of Namami Gange Mission-II in achieving its 2026 STP capacity targets." (GS-III)
• "Discuss the role of the Hybrid Annuity Model in financing urban sewerage infrastructure in India." (GS-III)
• "Evaluate the institutional architecture of the National Mission for Clean Ganga in the federal context." (GS-II)

10. Common Errors / Trap Areas

• Wrong ministry: NMCG sits under Jal Shakti, not MoEFCC.
• Confusing Phase I (₹20,000 cr) with Phase II (₹22,500 cr).
• NMCG is the executing authority; National Ganga Council is the apex policy body (PM-led).
• 2026 target is 7,000 MLD cumulative, not annual.
• The Assi–BHU STP is in Varanasi (UP), not Bihar; Kankarbagh STP is in Patna (Bihar).
• Phase II sanctioned 218 projects (sewerage) — do not conflate with all 450+ programme projects.
