I was walking past an unnamed bylane in my neighborhood, known to be rather dirty and untidy usually; I was pleasantly surprised to find this common and effective approach to prevent garbage dumping.
Upon inquiry, I learnt that area residents and worshippers at a chapel nearby worked with the local ward councilor to implement it. I plan to observe how long it lasts and replicate it elsewhere!

Encouragingly, this lane has been garbage free for nearly 15 consecutive months – Providential, eh?
