A 2017 study found an antifungal at high concentration and drug-resistant bacteria in Hyderabad sewage. India proposed discharge limits for 121 antibiotics in 2020 and left them out of the 2021 final rule.
2020 draft versus 2021 final rule.
Status As of March 2026: the 2021 rule contained no antibiotic limits and none of 17 benchmarked companies measured at the pipe.

What happened
A team led by Christoph Lübbert reported in 2017 that Hyderabad sewage contained fluconazole at up to 236,950 micrograms per litre, and that more than 95 per cent of samples held carbapenemase-producing bacteria, according to Chemistry World.
In 2020 India's environment ministry published a draft with discharge limits for 121 antibiotics. The final rule of 2021 contained no antibiotic limits. AMR Insights reported that the industry association had asked for limits to be targets rather than binding standards.
A 2026 antimicrobial resistance benchmark found that all companies reporting compliance measured it in the receiving water after dilution, and that none of 17 companies measured at the pipe.

Recorded
- Hyderabad sewage contained fluconazole at up to 236,950 ug/L; more than 95 per cent of samples contained carbapenemase-producing bacteria.
- The 2020 draft set limits for 121 antibiotics; the 2021 final rule set none.
- None of 17 companies measured discharge at the pipe, as the WHO recommends; compliance was measured in the receiving water after dilution.

Record
- None on record No penalty and no antibiotic discharge limit were recorded in the sources reviewed.
- Insufficient Reported but not independently verified: a 2007 Nature report that effluent from a treatment plant serving about 90 bulk drug makers in Patancheru contained ciprofloxacin at 31 mg per litre.
- None on record The identities of the companies in the 2026 benchmark are not given in the sources reviewed.
