Sure if there's a mix of homes with and without salt water. However i think you're wishful if everyone is surviving on bottles. You can only help your neighbor if you went to the store and bought water. And that supply would go quickly.

You can desalinate it with a solar still rather easily..

You only need a kids paddling pool, a bucket, a (clean!) tarp and a brick.
