Under Namami Gange Programme, as of October 2025, a total of 513 projects have been sanctioned at a cost of ₹ 42,019 crore, out of which 344 projects have been completed. The majority of the projects pertain to creation of sewage infrastructure as the untreated domestic/industrial wastewater is the main source of pollution in the river. Under the Programme, a total of 216 number of sewerage infrastructure projects costing ₹ 34,809 crores have been taken up for remediation of polluted river areas with treatment capacity of 6,561 Million Liters per Day (MLD). Of which, 138 STP projects with a capacity of 3,806 MLD have been completed and made operational.

Central Pollution Control Board (CPCB), carries out manual water quality monitoring of the river Ganga at 112 locations across five Ganga main-stem States- Uttarakhand-19; Uttar Pradesh-41; Bihar-33; Jharkhand-04; and West Bengal-15.

As per CPCB report on Polluted River Stretch (PRS) 2025 following information about Ganga main stem pollution is available:

Ganga Main Stem – State-wise Comparison (2018 vs 2025)

State	2018 Polluted Stretch	Priority (2018)	2025 Polluted Stretch	Priority (2025)	Trend/Observation
Uttarakhand	Haridwar→Sultanpur	IV	No PRS	—	Improved and PRS stretch removed
Uttar Pradesh	Kannauj →Varanasi	IV	Bijnor → Tarighat	IV / V	Partially improved
Bihar	Buxar to Bhagalpur	V	Bhagalpur D/S → Khalgaon D/S	V	Marginal pollution remains
Jharkhand	No PRS	—	No PRS	—	—
West Bengal	Triveni →Diamond Harbour	III	Baharampore →Diamond Harbour	V	improved

 

Based on the water quality data (median values) of the river Ganga for the year 2025 (January to August), the following observations are made.

1. pH & Dissolved Oxygen (DO) are the most critical parameters of river health. The pH & DO of River Ganga meet the required norms for bathing criteria at all the locations of River Ganga.
2. Water quality of river Ganga is conforming with the bathing criteria w.r.t. Bio-chemical Oxygen Demand (BOD) in the entire stretch of river Ganga in Uttarakhand, Jharkhand, Bihar & West Bengal, except the following locations/stretches:

• Farrukhabad to Purana Rajapur, Kanpur.
• Dalmau, Raibareilly.
• D/s Mirzapur to Tarighat, Ghazipur (except two locations namely U/s Varanasi, After confluence Gomti & U/s Ghazipur) in Uttar Pradesh.

As per the biomonitoring conducted during 2024-25 at 50 locations along river Ganga and its tributaries and 26 locations along River Yamuna and its tributaries, the biological water quality (BWQ) predominantly ranged from ‘Good’ to ‘Moderate’. The presence of diverse benthic macro-invertebrate species indicates the ecological potential of the rivers to sustain aquatic life.

The population of dolphins in the river Ganga has shown a marked increase over the past decade. From an estimated baseline of 2500 to 3000 individuals in 2009, the population rose to approximately 3500 in 2015 and further to around 6327 individuals as per the nationwide survey conducted during 2021-2023. This represents more than a twofold increase since 2009. In the Ganga basin the 2021-2023 assessment across 17 tributaries confirmed dolphin presence in multiple rivers where they were previously unrecorded, such as the Rupnarayan, Girwa, Kauriyala, Baba, Rapti, Bagmati, Mahananda, Ken, Betwa, and Sind.

Cleaning of river is a continuous process and Government of India is supplementing the efforts of the State Government in addressing the challenges of pollution in river Ganga and its tributaries (including river Yamuna) by providing financial and technical assistance under Namami Gange Programme.

The budgetary allocations (Revised Estimates) for the Namami Gange Programme during last 5 years [from financial year (FY) 2020-21 to FY 2024-25] are ₹ 11,100 crore. However, no State-wise allocation is made under the Namami Gange Programme.

The amount disbursed for implementation of State specific projects/interventions under the Namami Gange Programme during last five years (i.e. FY 2020-21 to FY 2024-25) and in current financial year till 30 November 2025, compiled State-wise, is enclosed at Annexure.

The information was provided by THE MINISTER OF STATE FOR JAL SHAKTI SHRI RAJ BHUSHAN CHOUDHARY in a written reply to a question in Rajya Sabha today.
