There are 97 towns along the main stem of river Ganga. The waste water generated from these 97 towns is approximately 3000 Million Litres per Day (MLD), the State-wise details are given as under:

 

State	Sum of sewerage generation from 97 towns along the Ganga (in MLD)	No of towns in the state
West Bengal	1413.8	39
Uttar Pradesh	961.6	20
Bihar	481.7	20
Uttarakhand	84.7	16
Jharkhand	12.8	2
Total	2954.6	97

As informed by Central Pollution Control Board (CPCB), as per estimate made during 2020-21, 1080 Grossly Polluting Industries (GPIs) operating in river Ganga main stem States have potential to discharge about 280.18 MLD of waste water with pollution load in terms of Biochemical Oxygen Demand (BOD) of 9.69 TPD into river Ganga & its tributaries. State-wise information is as under:

 

State	No. of GPIs	Wastewater discharge (MLD)	BOD Load (TPD)
Uttarakhand	55	52.42	1.44
Uttar Pradesh	913	139.41	4.58
Bihar	53	9.87	0.43
Jharkhand	5	0.14	0.002
West Bengal	54	78.34	3.23
Total	1080	280.18	9.69

MLD: Million liters per day; TPD: Tones per day

Government of India is supplementing the efforts of the State Governments in addressing the challenges of pollution in river Ganga and its tributaries by providing financial and technical assistance under Namami Gange Programme. Under this Programme, a diverse set of interventions for cleaning and rejuvenation of river Ganga have been taken up including waste water treatment, solid waste management, river front management (ghats and crematoria), maintaining continuous flow, rural sanitation, afforestation, biodiversity conservation and Public Participation etc. A total of 374 projects are taken up at a sanctioned cost of Rs.31098 crore, out of which, 210 projects are completed. The projects are also taken up along the main stem towns of river Ganga as well as on 15 tributaries namely Yamuna, Kosi, Saryu, Ramganga, Kali (West), Kali (East), Gomti, Son, Barakar, Hindon, BurhiGandak, Banka, Damodar, Rispana-Bindal and Chambal.

Till date 161 sewerage infrastructure projects have been sanctioned to abate the pollution from main stem towns (97 no.) of river Ganga and tributaries. These 161 sewerage infrastructure projects have been sanctioned to create / rehabilitate 5,015 MLD sewage treatment capacity along with laying of 5134 km of sewerage network. Out of these 161 projects, 92 projects are completed and rest of the projects is at various stages of implementation. With the completed projects, 1643 MLD Sewage Treatment Plant (STP) capacity has been created/rehabilitated and 4156 km sewer network has been laid. In addition, other initiatives like in-situ treatment of drains through bioremediation, fecal sludge management have also been taken up.

 

The number of STPs installed in the entire stretch of Ganga under the National Mission for Clean Ganga (NMCG) since 2016 till June 2022, year wise is given below:

 

SI No.	Year	No. of STP	Capacity in MLD
1	2016	8	123.9
2	2017	6	30.45
3	2018	7	190.06
4	2019	9	56.15
5	2020	19	141.55
6	2021	9	124.39
7	2022	10	169.3
Total		68	835.80

 

Under the Namami Gange Programme, CPCB is carrying out monitoring for assessment of River Ganga water quality at 30 locations in Uttar Pradesh through the Uttar Pradesh Pollution Control Board (UPPCB). River water quality is assessed for primary water quality criteria notified for outdoor bathing in terms of Bio-chemical Oxygen Demand (≤3mg/L). Sampling was carried out on fortnightly basis and the data of year 2021 (January to December) was analysed using statistical tool median which is a measure of central tendency.

Out of 30 locations monitored, river Ganga is meeting the primary water quality criteria for bathing at 16 locations with respect to BOD in Uttar Pradesh in the stretch from (i) Madhya Ganga Barrage (Bijnor) to Kannauj D/S (ii) Kadaghat (Prayagraj) to U/S, Vindhyachal (Mirzapur) and (iii) U/s Varanasi (Assighat). The BOD at rest of the 14 locations is in the range of 3.1 mg/l to 4.2 mg/l with marginal exceedance.

 

This information was given by the Minister of State, Shri Bishweswar Tudu in a written reply in Rajya Sabha today.
