If you do not have access to a piped supply of safe water, you will need to treat your water before you use it for drinking or food preparation to ensure that it is safe.
Q: How can I make sure that the water I’m drinking is safe?
A: If the water is very dirty, it may be necessary to pre-treat it
by filtering it or decanting it to remove any visible debris. You
will then need to purify the water – one of the simplest and most
effective ways is to use water purification tablets.
