Some bottled water aren't safe to drink, this is why it is advisable to treat your water yourself because health is important.
While in Ondo, there were some houses who wouldn't want another fetcher to go into their well but theirs only and it keeps their water clean. I don't drink well water because of my experience with typhoid and it is why I am being careful today.
Clean water is good for the health.
