<p>Owing to rapid urbanisation in most parts of the state, sewage is generated in Karnataka cities at the rate of 3356.5 MLD (million litres per day), of which only 45 per cent (1513.5 MLD) is treated, said a report.</p>.<p>The Central Monitoring Committee set up by the National Green Tribunal to study and suggest remedial measures to check river pollution in the state, stated this in its report submitted to the Green Bench.

Treated water is used mostly for recharge of lakes, industrial establishments, by horticulture departments and for gardening, said the report.</p>.<p>In the state, a total of 3,503 industries generate 1,339 MLD polluting water, of which 3,289 industries have set up effluent treatment plants having the capacity to treat 4,532 MLD polluted water.</p>.<p>Total 17 river stretches have been identified as 'pollutant stretch' in the state, in which Tunghabhandra river has been selected for model development of rejuvanation.</p>.<p><strong><a href="https://www.deccanherald.com/international/how-a-kerala-based-scientist-is-using-sewage-to-detect-covid-19-in-australia-955134.html" target="_blank">Read | How a Kerala-based scientist is using sewage to detect Covid-19 in Australia</a></strong></p>.<p>In the entire country, 48,004 MLD of sewage (from urban settlements) was being generated in 31 States/ UTs.
