Where is the country's first four-storey sewage treatment plant for a municipality built under Namami Gange?

The Namami Gange Programme was launched in that year as an integrated conservation mission with the twin objectives of effective abatement of pollution and the conservation and rejuvenation of the National River Ganga.

This technology was brought to India through the programme and improves upon the activated sludge process and the sequential batch reactor by adding fixed artificial media and plant roots, which gives it a smaller footprint, lower power use and nutrient removal.

The nationwide drive opened on 20 October 2026 and continues to 8 November 2026, a window chosen so that it covers the days before the festival, when firecrackers are bought, as well as the days after it, when air quality usually stays poor.

Citizens have been asked to celebrate a clean and green Diwali in line with this mission, whose approach is to change everyday habits rather than wait for large interventions, and the pledge items follow from it directly: no firecrackers, earthen diyas and energy-efficient lights, no single-use plastic, waste segregated at…

The campaign is nationwide, but the cities covered under the National Clean Air Programme, numbering 130, have been singled out for special attention, because that is where the burden on air quality is heaviest and where a cracker-free festival makes the greatest difference.
