For eight consecutive years, Indore held the top spot in India’s annual cleanliness rankings.
On 11 November 2026, that run ended in New Delhi, where President Droupadi Murmu presented Navi Mumbai’s Mayor, Sujata Patil, with the cleanest city award at the 10th Swachh Survekshan Awards. Navi Mumbai finished first in the Super Swachh League among 4,751 cities, ahead of Surat and Vijayawada.
The result has revived a comparison with Mumbai, the city next door, and a common misconception that needs clearing up.
A twin city, but not a suburb
Many people assume Navi Mumbai is simply part of Mumbai, which is not the case.
It was planned as a satellite city across Thane Creek after Greater Mumbai’s population doubled from three million to nearly six million between 1951 and 1971, and the City and Industrial Development Corporation (CIDCO) was formed in 1971 to build it on marshland and former village land.

The Navi Mumbai Municipal Corporation (NMMC) began functioning only in 1992, governs the nodes from Airoli to Belapur, and is headed by its own mayor and municipal commissioner, while Mumbai is run by the Brihanmumbai Municipal Corporation (BMC).
Navi Mumbai grew out of Mumbai’s need for space but was never carved out of the older city, so the award belongs to the NMMC alone, and its significance is clearest against the city it displaced.
What Indore got right first
To see what Navi Mumbai had to beat, start with Indore’s long reign, which rested on unglamorous sequencing. Its corporation began a door-to-door collection pilot in two of 85 wards in January 2016 and reached 100% coverage by the end of that year, according to a Global Methane Initiative case study.
Households now separate waste into six streams, a GPS-tracked fleet reports to a central command centre, and fines for non-segregation and littering back the system, as the city’s former collector has written.

Its bio-CNG plant also turns wet waste into fuel for city buses. Indore remains a strong performer, finishing second in the new Mentor City category behind Ahmedabad, so overtaking it required more than a copy of its model.
How Navi Mumbai pulled ahead
Navi Mumbai, which placed third behind Indore and Surat in the previous edition, built comparable discipline and added layers of its own. Its Integrated Command and Control Centre tracks garbage vehicles by GPS, and residents file complaints and follow their resolution through the MyNMMC app and a Citizen Grievance Portal.
The city has held the Seven-Star Garbage-Free City rating and Water Plus certification, treats 100% of its sewage, and has curbed plastic while drawing students and youth into cleanliness drives.
Waste and Recycling magazine describes its Textile Recovery Facility at Belapur, built with the Union Ministry of Textiles’ Textile Committee, as the country’s first municipal facility of its kind, though housing societies were slow to adopt the bins and segregation at source remains inconsistent.

Commissioner Dr Kailas Shinde credits technology and public participation, and the NMMC dates the climb to three to four years of sustained effort under the motto Nischay Kela, Number Pahila, meaning determined to be number one. The same measures tell a different story in Mumbai.
Where Mumbai stands
In the 2024-25 survey, Greater Mumbai was listed eighth among the 10 lowest-scoring cities with populations above 10 lakh, according to Deccan Herald.
The BMC handles more than 6,500 tonnes of waste a day, around 5,900 tonnes of it going to the Kanjurmarg landfill, and Free Press Journal reports that limited public participation and the lack of 100% segregation have slowed its goal of a zero-garbage city by 2030.
Air quality adds to the strain. Newslaundry counted only seven days of ‘good’ air across the five winters from 2021 to 2026, and the BMC identifies construction dust as a major contributor, with around 3,200 active construction sites.

The BMC counts 231 good or satisfactory air days up to 22 October 2026, against 218 in 2025, so the trend is mixed. Each of these problems has a counterpart in Navi Mumbai’s methods.
What Mumbai can borrow
Three practices stand out, and each answers a gap described above. The first is enforced source segregation, since the BMC has yet to reach 100% segregation. Indore piloted collection ward by ward and backed it with fines, and the Solid Waste Management Rules 2026 now require four-way segregation nationwide, with bulk waste generators processing waste on site.
The second is live monitoring, which matters at the scale of the BMC’s 6,500 tonnes a day, and both Indore and Navi Mumbai track collection vehicles from command centres.
The third is recycled water for dust. The NMMC has made tertiary treated water mandatory at construction sites and uses it in dust-suppression vehicles and road washing, a practical answer to the dust that the BMC names as a major contributor to pollution.
Mumbai’s scale will make the task harder, and experts quoted by Newstrack call the ranking only a first step, with year-round upkeep the real test. The NMMC is already preparing a Sugandhi Shahar Abhiyan, or Fragrant City Campaign, to build on the win.
