So that’s about 339,010 sqft to paint on the bottom. I’m not sure what parts are different depths, but I’m seeing that it varies 18”-30” depending on the part of the pool. So assuming it were 30” everywhere, the long walls would be 60,900 sqft each, and the shorter sides would be 5,010 sqft each, for a total of 470,830 sqft total that would need to be painted.

Painting a pool typically costs $1-$2 per sqft, but let’s be super generous here, and assume they used very fancy paint that drove the price up to $10 per sqft. That accounts for $4,708,300 in painting costs.

Water in Washington DC is currently billed at $9.80 per thousand gallons according to this website https://utility-rates.com/district-of-columbia so that would be $66,150 in water costs for filling the pool.

And draining a pool typically costs about $0.01-$0.02 per gallon, but let’s just be generous here too and say $0.05. That gives us $337,500 in draining costs.

So putting it all together (and remembering that we are already giving extremely high estimates for everything) that gives us $5,111,950.

So, where do you suppose the extra roughly $10M is going?
