In Bnei Braq someone started a "cold water gmach" and put out on the street a number of bottles of cold water and cups, for use by the overheated public.

It is only 3 bottles, but the person behind it probably goes out and refills them every now and then.
As I mentioned, such gmachs have been seen before. In RBS, there is someone who puts out a cooler of water for the public during the hot summer Shabbos days. I am confident that this happens in other places as well.
Entirely new or not, it is a big chessed and very thoughtful of the person behind it.
Keep cool, and drink a lot
