Discuss the role of sector-specific Charters and CETPs in moving from pollution control to pollution prevention in India's river basins.

Pollution control cleans effluent at the end of the pipe. Pollution prevention cuts waste at its source through cleaner processes and water reuse. Under Namami Gange, sector-specific Charters and Common Effluent Treatment Plants (CETPs) lead this shift. Annual inspections of Grossly Polluting Industries (GPIs), supported by CPCB, back them up [1].

Sector-specific Charters: prevention at source

• Targeted sectors: Pulp & Paper, Sugar, Distillery, Textile and Tannery make up about 70% of GPIs and 88% of the Ganga basin's pollution load [1].
• Process change, not just treatment: the Charters require lower freshwater use, less wastewater, upgraded ETP/RO systems and water recycling. The end goal is no untreated discharge [1].
• Business case: using less water and fewer chemicals lowers input costs, so industry gains from complying [1].
• Regulatory teeth: third-party institutes check each unit against its SPCB Consent to Operate and record geo-tagged evidence [1]. Defaulters face closure under Section 5, EP Act, 1986 [2].

CETPs: making compliance affordable for clusters

• Reaching MSMEs: a GPI is a unit with a BOD load of 100 kg/day or more, or one that handles hazardous substances [3]. Smaller units fall outside the annual inspections, but a shared plant can treat their combined effluent.
• Cluster examples: Jajmau (20 MLD, Kanpur tanneries) and Mathura (6.25 MLD) are complete. Banther (4.5 MLD) is still pending [4].
• Economies of scale: a shared plant lowers the treatment cost for each unit.

Outcomes and gaps

• Ganga-basin GPI compliance rose from 39% (2017) to 86% (2025). BOD load fell 72.46%, but effluent volume fell only 21.24% [1]. The gains came mostly from better treatment, not less discharge, so prevention is still incomplete.
• CETPs are themselves end-of-pipe plants. CAG found that only 17 of 120 required CETP adequacy checks had been done [5]. An overloaded CETP can hide non-compliance.
• Enforcement capacity is thin. CPCB carried out only 63% of the GPI compliance checks it was required to do in 2011–17 [6].
• Programme funding was assured only until March 2026 [4].

Charters change the question from "how much is treated" to "how much is generated", and CETPs bring small clusters into the same discipline. Next steps should be OCEMS for every GPI, public compliance data for each unit, binding recycling targets in the Charters, and assured CETP funding beyond Phase-II. Together, these can turn a regulatory success into lasting prevention, in line with Article 48A and SDG 6.3.
