Lack of public dustbins was the main reason for Bengaluru’s fall in the rankings. The city’s failure to declare it open defecation free was another reason for its poor performance. 

The areas of evaluation for Swachh Survekshan are waste collection, sweeping and transportation, solid waste processing and disposal, information,  education and behaviour change, capacity building - SBM e-learning portal and open defecation free or toilets.

The Bruhat Bengaluru Mahanagara Palike Commissioner, Manjunath Prasad, told The New Indian Express, “One should not consider the drop in rank from 38 to 210. Most cities out of the 434 have a population of 50,000 to 1 lakh and up to 10 lakh. It is not fair to compare cities with a population of 50,000 to 1 lakh with Bengaluru whose population is 1.2 crore.”

Manjunath Prasad explained that the survey was scored for 2,000 points with 40% weight given to waste collection, sweeping and transportation, 20% to solid waste processing and disposal, 30% to open defecation free or toilets and 5% each to information, education and behaviour change and capacity building - SBM e-learning portal.

The drop is attributed to the fact that there was mismanagement of waste disposal infrastructure and the weak implementation of initiatives such as waste segregation, garbage collection and penalising citizens who dump garbage on the streets.

The BBMP has developed a roadmap to improve their ratings next year. BBMP joint commissioner (health) Sarfaraz Khan has said that they will build 36,000 toilets across the city as well as improve solid waste management.
