The answer is simple - there is no functioning city level garbage collection/disposal system. Outside of a handful of cities, there is no system to regularly collect garbage and dispose it properly. This is due to the sheer size and population of the cities combined with government and citizen apathy, lack of manpower, lack of funds, lack of knowledge etc. Lets see how it works generally in cities - millions of homes do their daily cleaning, there is no where to dump this garbage, so it is thrown street side or somewhere in a nearby small dump (https://scroll.in/article/802978/as-garbage-continues-to-pile-up-in-east-delhi-a-lesson-on-how-to-better-manage-our-waste https://scroll.in/article/802978/as-garbage-continues-to-pil...), then it is not collected for weeks, finally when it is collected it is thrown in a bigger dump (https://www.newsweek.com/trash-mountain-india-could-taller-taj-mahal-next-year-1442227 https://www.newsweek.com/trash-mountain-india-could-taller-t...). Only Indore that I know of (https://www.outlookindia.com/national/how-indore-became-the-cleanest-city-in-india-for-the-sixth-time-news-227284 https://www.outlookindia.com/national/how-indore-became-the-...) is doing proper garbage collection and disposal. p.s. my knowledge may not be fully up-to-date.
