Quite right, but excavation and hauling the dirt off-site is very expensive. And the way they're building subdivisions these days, you can't even fit a Bobcat through the side yard gates any more.
I've seen underground storage systems so huge and elaborate that they are integrated with water features - even waterfalls and ponds. They are appropriate (in scale and cost) for some commercial places that want to make a statement - like corporate HQs or upscale office buildings. Or for someone who just wants to keep up with the Joneses, I guess.
Well, I imagine they're also appropriate where the need for water outweighs the cost. Even an underground storage cistern is cheaper than digging a well in arid regions. And in most regions, digging a well gets more expensive every year. The water table here is 400 feet lower than it used to be.
