What's the best way to remove water in my gas tank?

What is your question?

So I was having a no starting issue I have found out that someone put about a gallon to a gallon a half of water in my gas tank that had about 7 gallons of gas in it. I'm wondering what do I need to do to make my car okay I just had a motor put in it four months ago. Please help. I'm sick that some punk kids in my neighborhood would do something so s*****. They also smashed my windshield and broke a back window and left their footprints all over the hood of my car.

What makes this problem better or worse?

The car won't start.
