LOUISVILLE, Ky. (WDRB) - Mike Mobley is boasting that he has the world's biggest residential swimming pool in the small city of El Campo, Texas.

It includes a 500 foot lazy river, rock-climbing wall, sunken bar, and a 21 foot water slide. The pool holds 600,000 gallons of water and includes a tree with rope swing.

It's become the talk of the town, which Mobley says is open to anyone who wants to take a splash anytime.

The total cost to build the pool is $3 million.

The costs don't end there. The Mobleys pay $1,200 a month in utility bills.
