Namami Gange Programme and Ganga Rejuvenation Plan

Environment & Ecology › Environmental Institutions and Schemes in India · Topic 19.12

Namami Gange is the Government of India's flagship programme, announced in 2014 and approved in May 2015 as an integrated conservation mission, with an outlay of Rs 20,000 crore for the period 2015 to 2020, to achieve the twin objectives of effective abatement of pollution and conservation and rejuvenation of the river Ganga. It followed the Ganga Action Plan, launched on 14 June 1986 by Rajiv Gandhi, and its second phase from 1993, which spent large sums on sewage interception and treatment but fell short because of poor operation and maintenance. Namami Gange is implemented by the National Mission for Clean Ganga (NMCG), with states and local bodies. Its main pillars are sewage treatment infrastructure, river-front development including ghats and crematoria, river surface cleaning, biodiversity and afforestation, industrial effluent monitoring, rural sanitation and public awareness. It uses new models such as the Hybrid Annuity Model for sewage plants, in which the private operator is paid for performance for 15 years, and One City One Operator, along with Ganga Gram villages, the Arth Ganga idea of linking the economy with the river, and the Ganga Praharis. The programme was extended to 2026 with a budget of about Rs 22,500 crore. Targets include 'aviral' (continuous flow) and 'nirmal' (clean) Ganga, but water-quality improvement has been uneven, and issues include sewage gaps, industrial discharge and low flows.

Where Does It Fit?

This topic starts the river cleaning section of the macro, which continues with the Ganga’s administrative bodies, the National River Conservation Plan and sanitation schemes. Previous topic: National Solar Mission. Next topic: National Mission for Clean Ganga and Ganga Task Force.

What Are the Pillars of Namami Gange?

Pillar	Content
Sewage treatment infrastructure	New and rehabilitated sewage treatment plants, sewer networks and Common Effluent Treatment Plants
River-front development	Ghats, crematoria and other facilities along the river
River surface cleaning	Skimming of floating waste and trash
Biodiversity	Conservation of fish, dolphins and turtles
Afforestation	Planting along the river
Industrial effluent monitoring	Real-time monitoring of polluting industries
Public awareness	Ganga Praharis, Ganga Gram, campaigns and participation

Which Models and Results Stand Out?

Hybrid Annuity Model: private firms build and run the plants for 15 years, with 40 percent paid during construction and the rest as annuity
One City One Operator: a single operator for sewage infrastructure in a city
Arth Ganga: idea launched in 2019 to link economic activity with river conservation
Ganga Gram: villages on the banks developed with sanitation
Open defecation: Ganga bank villages were declared open defecation free
Sewage capacity: hundreds of projects sanctioned and many completed
Water quality: improvement in some stretches, but pollution remains in the middle and lower Ganga
Challenges: gaps in sewer networks, drains, industry and low flow

What Else Should You Remember?

Ganga Action Plan I: launched 14 June 1986 with 100 percent central funding
Ganga Action Plan II: from 1993, merged into the National River Conservation Plan
National Ganga River Basin Authority: created in 2009 under Environment (Protection) Act
National Mission for Clean Ganga: implementation arm
National Ganga Council: replaced NGRBA in 2016, chaired by the PM
Namami Gange 2.0: extended to March 2026
Funding: 100 percent central funding for the programme
Ganga basin: the basin covers 11 states, with 5 main stem states: Uttarakhand, Uttar Pradesh, Bihar, Jharkhand and West Bengal
Ganga length: about 2,525 km
Haridwar to Kolkata: most polluted stretches include Kanpur and Varanasi
Kanpur tanneries: the Jajmau area faces tannery effluent
Varanasi: ghats and crematoria were redeveloped
Ganga Praharis: volunteers who monitor the river
Ganga Vahini: boat patrols
Eco Task Force: Territorial Army battalions deployed for afforestation and bank protection
Aviral Dhara: uninterrupted flow
Nirmal Dhara: unpolluted flow
Environmental flows: notification of 2018 requires minimum flow in the river
Ganga dolphin: National Aquatic Animal
NGT orders: Tribunal orders repeatedly on Ganga cleaning
CAG and parliamentary reports: noted slow spending and delays
Link to previous: see National Solar Mission
Link to next: see National Mission for Clean Ganga and Ganga Task Force
Link to dolphin: see Ganges Dolphin Project
Caution: funds, targets and water quality data change, so check NMCG
Exam hint: remember GAP 1986, Namami Gange 2014/2015, Rs 20,000 crore, NMCG and HAM
Industrial effluent: grossly polluting industries along the Ganga are directed to install online monitoring and zero liquid discharge
Sewage gap: the basin cities generate far more sewage than treatment capacity, so projects target the biggest drains first
Biodiversity centres: rescue and conservation centres for gharial, turtles and dolphin research are supported
Ghat development: ghats and crematoria are improved to reduce direct pollution
Local participation: Ganga Praharis, schools and city groups take part in cleaning and awareness
Rural sanitation: villages on the banks were made open defecation free under the Swachh Bharat Mission
Wetlands and floodplains: protection of floodplains and wetlands supports flows and groundwater recharge
Monitoring: real-time water quality monitoring stations report to a public dashboard
Aviral and nirmal: the programme speaks of aviral (uninterrupted) and nirmal (unpolluted) flow of the Ganga, a goal that needs both environmental flows and clean water

Why Does It Matter for the Exam?

GAP: 1986
Namami Gange: 2015, Rs 20,000 crore
Agency: NMCG
Current affairs link: Arth Ganga
Common errors: giving the Ganga Action Plan launch year as 1996

As an analytical point, Namami Gange moved from building plants to ensuring that they run, by paying operators for performance. Real success also needs sewerage to reach the plants, industries to treat waste and enough water left in the river.

Frequently Asked Questions

What is the Namami Gange Programme?

Namami Gange is a flagship programme announced in 2014 and approved in 2015, with an outlay of Rs 20,000 crore, to clean and rejuvenate the Ganga. It focuses on sewage treatment, river-front development, river surface cleaning, afforestation, biodiversity, industrial effluent monitoring and awareness, and is implemented by the National Mission for Clean Ganga.

Why did the Ganga Action Plan fall short?

The Ganga Action Plan, launched in 1986, built sewage interception and treatment plants but many plants were poorly operated or lay idle for lack of power and maintenance. Cities kept growing, industries kept discharging effluent, and flows fell, so water quality did not improve as expected, which shaped the design of Namami Gange.

What is the Hybrid Annuity Model in Namami Gange?

Under the Hybrid Annuity Model, a private operator builds a sewage treatment plant and runs it for 15 years. The Government pays 40 percent of the cost during construction and the rest as annual payments linked to performance, which ensures the plant works well. It addresses the poor operation and maintenance seen in earlier programmes.

What is Arth Ganga?

Arth Ganga is a concept presented by the Prime Minister in 2019 at Kanpur, which aims to link the economy with the river by promoting sustainable livelihoods, zero budget natural farming along the banks, monetisation of sludge and wastewater, public participation and river-based tourism, so that the river's health and local incomes improve together.

What are the challenges in cleaning the Ganga?

Challenges include incomplete sewer networks, cities generating more sewage than treatment capacity, discharge from industries such as tanneries, agricultural runoff, religious and cremation practices, and low flow due to dams and withdrawals. Environmental flow norms, strong enforcement and public participation are needed alongside infrastructure.
