According to a survey based on solid waste management practices in towns across the country the places which topped the list were Alappuzha in Kerala, Panaji and Mysuru. A latest rating by Centre for Science and Environment said that Alappuzha, Panaji and Mysuru are three of the cleanest cities in India, with municipal waste management systems that actually work. The country's capital Delhi has appeared at the bottom of the list of 14 along with Chandigarh and Bengaluru. The survey found that the cities, figured at the bottom, like Delhi, Chandigarh and Bengaluru have managed to remain clean, but only by sweeping their garbage under the carpet. 53 cities with a population of above 10 lakhs each and 22capitals that do not have that much population were selected for the survey. Mysuru, Chandigarh, Tiruchirapalli, New Delhi Municipal Council, Visakhapatnam, Surat, Rajkot, Gangtok, Pimpri Chindwad and Greater Mumbai had emerged as the top 10 cities in terms of sanitation and hygiene in the government survey. But this particular survey was, however, limited to 14 cities, It tried to find out what actually makes these cities clean and how the best practices would act as a guide for future policy.
