Water can only be as deep as the container it is in. On earth the deepest it can be would be measured at the deepest point in the Ocean. That point is the Mariana Trench, which is almost 36,000 ft (6.8 miles) deep. However, this is not a limit of the water. Only a limit of the earth.
The Challenger Deep in the Mariana Trench is the deepest point on Earth, reaching a depth of about 36,070 feet below sea level.
