(Query received over email from Ganesh Ms)
Dear Sir/Madam,
I have seen your video in youtube on barrel biosand filter and require guidance on how to filter muddy open well water to drinkable quality. Can your organisation help me in this regard?
The well is 20 ft deep and we need to filter contaminants and muddy water (Koramangala was once a lake; as you know, the muddy water is due to clay mud)
