 Abstract: The ongoing pandemic of viral infections due to the novel coronavirus disease (COVID-19) is known to have affected about 17.19 million people globally and approximately 1.58 million people in India as of July 30, 2020. The pandemic being quite persistent in nature, timely planning for novel and adaptive interventions are required for dealing with it, with a view to detecting the early signs of infection, as well as, controlling the spread of the outbreak towards the uninfected population residing at comparatively safer zones. Although inter-personal physical contacts have been the dominant of transmission for the SARS-CoV-2 (COVID-19), evidence of gastrointestinal symptoms caused by SARS-CoV-2 infections, accompanied by the detection of viral RNA in the faeces of infected individuals, with high probability of their presence in wastewater samples, makes an important case for thorough characterization and quantification of the pathogenic materials present in  the municipal sludge generated in urban centres.  This becomes even more important in the case of metro-cities and dense urban centres, where the chance of the medical wastes from the COVID hospital facilities coming into the municipal sewage stream is highly likely. However, the pathogens in the municipal sewage stream become concentrated in the sludge, providing an opportunity to treat the separated sludge from the wastewater stream using a technology of irradiation called ‘sludge hygienisation’ to curb the outbreak of the virus.  The present work provides an assessment of the sludge hygienisation technology for its suitability as an option to eradicate the viral particles accumulated in the sludge samples from urban environments. Such an intervention would prove to be instrumental in containing the present and future outbreaks, ensuring that the community healthcare systems are saved from being pushed to the limits owing to the increasing pressure on the infrastructure.
