Where does Mumbai get its water from?

I’m in the middle of various changes in lifestyle which I’m trying to
make consciously. Today, I thought I needed a good dock to start out
from and could think of no better place than Mumbai. I’m now out
asking the question: Where does Mumbai get its water from?

Over the next few days when I get the time, I will re visit this topic
here. I will try and document this journey as much as possible.

I see this as possibly a first step in answering the question of
rethinking the way mega cities and at the micro level consume water so
that we can get water conservation measures out of the clean the
beaches and close the tap mode.
