Why is this in the news?

The Press Information Bureau (PIB) released an official update on 06 August 2026 detailing the progress of the Namami Gange Programme (NMG-II) during 2025, highlighting the commissioning of 25 new Sewage Treatment Plants (STPs) under 70 sewerage infrastructure projects, the creation of 4,263 MLD sewage treatment capacity, and significant strides in biodiversity conservation, including the rescue and rehabilitation of aquatic species such as the Gangetic dolphin, turtles, and crocodiles. The report also underscores improvements in water quality across polluted river stretches and the ecological restoration of wetlands and riverine habitats.

Background

• The Ganga River, a transboundary river system, is the lifeline of over 40% of India’s population, supporting agriculture, industry, and cultural heritage across five states: Uttarakhand, Uttar Pradesh, Bihar, Jharkhand, and West Bengal.
• The Namami Gange Programme, launched in 2014 as a flagship initiative of the Government of India, is a comprehensive, integrated mission to clean and rejuvenate the Ganga River and its tributaries through a multi-sectoral approach.
• The programme operates under the National Mission for Clean Ganga (NMCG), an autonomous body under the Ministry of Jal Shakti.
• The programme’s objectives include reducing pollution, conserving and rejuvenating the Ganga’s ecosystem, and ensuring sustainable management of the river basin.
• The Central Pollution Control Board (CPCB) periodically monitors and reports on the status of polluted river stretches (PRS) in the Ganga basin, classifying them based on water quality parameters such as Dissolved Oxygen (DO), Biochemical Oxygen Demand (BOD), and faecal coliform levels.
• The programme integrates scientific research, community participation, and technological interventions to address both point and non-point sources of pollution in the Ganga basin.

What is the Namami Gange Programme?

• The Namami Gange Programme is a centrally sponsored scheme under the Ministry of Jal Shakti, Government of India, aimed at the comprehensive rejuvenation of the Ganga River and its tributaries through a multi-dimensional approach.
• The programme focuses on three core pillars: (1) Sewerage infrastructure development, (2) Industrial effluent monitoring and control, and (3) River surface cleaning and biodiversity conservation.
• Under the programme, 70 sewerage infrastructure projects were commissioned in 2025, including 25 new Sewage Treatment Plants (STPs), adding 4,263 MLD of sewage treatment capacity to the Ganga basin.
• The programme has established a robust monitoring framework, including the identification and prioritisation of polluted river stretches (PRS), with regular assessments by the CPCB to track improvements in water quality.
• Biodiversity conservation is a critical component, with initiatives such as the rescue and rehabilitation of aquatic species (e.g., Gangetic dolphins, turtles, and crocodiles), habitat restoration, and the establishment of biodiversity parks.
• The programme has documented 215 fish species in the Ganga River, including 206 native and 9 exotic species, and has undertaken ‘river ranching’ by releasing 2.05 crore fish seeds to enhance fish populations.
• The NMCG has collaborated with institutions such as the Wildlife Institute of India (WII) to establish the National River Research Centre in Dehradun and four aquatic animal rescue and rehabilitation centres, including India’s first dolphin rescue ambulance.
• The programme also prioritises the restoration and management of wetlands in the Ganga basin, aligning with the Wetland (Conservation and Management) Rules, 2017, to enhance ecological resilience and water purification services.
