The Ministry of Jal Shakti has announced strengthened industrial pollution control measures under the Namami Gange Programme, moving from periodic inspections to continuous compliance monitoring. The approach combines annual inspections of polluting industries, independent technical assessments, and sector-specific pollution prevention charters to reduce industrial discharge into the Ganga and Yamuna rivers and their tributaries.
Key facts
- In 2025, 3,703 Grossly Polluting Industries (GPIs) were assessed across Ganga and Yamuna basins: 1,296 in Ganga basin and 2,407 in Yamuna basin
- Inspections covered 113 districts across six States and one Union Territory
- GPI compliance increased from 39% in 2017 to 70% overall in 2025, and to 86% in the Ganga basin alone
- Biological Oxygen Demand (BOD) pollution load in Ganga basin declined from 26 tonnes per day in 2017 to 7.16 tonnes per day in 2025, a 72.46% reduction
- Number of operational GPIs increased from 888 in 2017 to 3,154 in 2025
- 40 technical institutes nominated for the 2026 inspection cycle; 25 institutes participated in 2025
- 41 Common Effluent Treatment Plants (CETPs) assessed in 2025 across both basins, with 40 operational and combined capacity of 514.53 million litres per day
- Sugar sector freshwater consumption declined from 155 litres per tonne of cane in 2017 to 58 litres per tonne in 2025
- 60 recycled-fibre-based Pulp and Paper mills operate on Zero Liquid Discharge (ZLD)
- Approximately 719 million litres of groundwater saved daily; annual energy savings of 1,277.6 megawatts; estimated carbon reduction of 1,162.6 tonnes CO₂ equivalent annually
What changed: from reactive to preventive regulation
Industrial pollution control under Namami Gange has shifted from reactive enforcement to continuous self-improvement. Rather than inspecting industries only when problems arise, the Ministry now conducts mandatory annual inspections of all Grossly Polluting Industries in the Ganga basin. Inspections are detailed and scientific, examining consent-to-operate compliance, sampling water from treatment plant inlets and outlets, measuring pollutants like BOD (biological oxygen demand), COD (chemical oxygen demand), total suspended solids and total dissolved solids, checking for illegal bypasses, and examining recipient water bodies and groundwater quality. Inspection teams include independent experts from technical institutes, State Pollution Control Board officers and district officials, adding scientific credibility to findings.
Sector-specific charters for pollution prevention
The Ministry has developed water recycling and pollution prevention charters for five industries that together account for approximately 70 per cent of GPIs in the Ganga basin and 88 per cent of the pollution load: Pulp and Paper, Sugar, Distillery, Textile and Tannery sectors. These charters move beyond treating pollution after it forms to preventing pollution at source. They establish measurable targets for reducing freshwater consumption, minimising wastewater generation, upgrading treatment systems and promoting water reuse and recycling. For example, textile clusters are encouraged to adopt chemical management systems and eco-friendly dyes, while tannery clusters are recommended to implement cleaner production measures and improved primary effluent treatment.
Targeted action for high-pollution industries
In 2022, 246 industries identified as top pollution contributors were given priority action. The Ministry conducted 17 sector-specific workshops where 222 of these industries submitted pollution reduction action plans with short-, medium- and long-term goals. By 2023, 173 industries had achieved their short-term targets, 141 their medium-term targets and 126 their long-term targets. The pollution load from these priority industries declined by an estimated 65 per cent in 2022-23 compared with the previous year, dropping from 18.68 tonnes per day to 6.381 tonnes per day. As a result, 156 industries were removed from the priority list.
Strengthening collective treatment plants
Common Effluent Treatment Plants serve industrial clusters by providing shared wastewater treatment facilities. In 2025, 40 out of 41 CETPs assessed across the Ganga and Yamuna basins were operational, with a combined capacity of 514.53 million litres per day. However, only 27 were fully compliant with prescribed standards. The Ministry identified specific operational and technological gaps in each CETP and recommended targeted improvements such as better operation and maintenance, biological treatment upgrades, improved chemical practices and regular outlet water quality monitoring.
Resource efficiency and water conservation
The regulations have encouraged industries to view treated wastewater as a resource rather than waste. The Sugar sector has significantly reduced its freshwater consumption from 155 litres per tonne of cane in 2017 to 58 litres per tonne in 2025. The Pulp and Paper sector now operates 60 recycled-fibre mills on Zero Liquid Discharge, saving an estimated 928.89 million litres of groundwater daily. These improvements have come through technologies such as high-pressure boilers, condensate polishing units, tertiary treatment upgrades and wastewater recycling systems.
What this means for you
If you work in or own an industry near the Ganga or Yamuna rivers, your facility may now face mandatory annual inspections by independent technical teams. Compliance requirements are stricter and more transparent, with inspection reports submitted online. Non-compliant industries face Show Cause Notices and potential closure orders from State regulators. For industries adopting cleaner production and water recycling, the charters provide a roadmap for reducing operating costs while meeting pollution norms. Citizens living near industrial clusters should see gradual improvements in water quality in local tributaries and reduced incidence of pollution events. Students and researchers will find opportunities to participate as inspectors or advisors through the nominated technical institutes.
What happens next
The 2026 inspection cycle will be conducted with 40 nominated technical institutes. The Ministry continues to assess GPI compliance quarterly and will conduct sector-specific workshops for non-compliant industries. CETP assessments will continue to identify gaps and recommend improvements. The approach aims to establish a sustainable culture of responsible production, water conservation and pollution prevention as an integral part of environmental protection in the Ganga and Yamuna basins.
