Water Storage Tanks for Parking Lots

Parking Decks provide a wide range of possibilities, because we could build something underground, or use the deck as a foundation for something considered above-ground. Most of what I see is concrete, integrated into the structure itself. It's a compelling argument, to use some part of the structure that isn't suitable for anything else.
