"Tunywe maji salama"

Translation: We should drink safe water

[filixlan]

Maji safi is also more used in Tanzania

[filixlan]

You could choose a more different word from "safe" than "trustworthy"...

[SimonandNe]

I thought this construction was used more in the sense of "Let's drink" and to make it imperative would need something like lazima before it. Can anyone clarify from practical experience?
