I wouldn't say water is abundant. It is perceived as abundant because we see so much of it, but let me share some statistics.
"Water covers about 71% of the earth's surface. 97% of the earth's water is found in the oceans (too salty for drinking, growing crops, and most industrial uses except cooling). 3% of the earth's water is fresh. 2.5% of the earth's fresh water is unavailable. 0.5% of the earth's water is available fresh water" — usbr.gov
