QUESTION
Frequency of cleaning the borewell for silt

Hello,

We cleaned our borewell in 2016 for silt deposition problems due to which we got a rotten stinking smell in tap waters. I would like to know what is the exact frequency of cleaning borewell for a silt problem? I am again getting rotten smell in my borewell now. Previously it was cleaned in 2016. It's a 300 feet borewell.

Thanking you
