If applicable, you will have to pay a small “excess/deductible” charge - and my receive a reconditioned iPad in exchange for your water-damaged device.

If you don’t have an AppleCare+ Plan, if the iPad is damaged, you will have no alternative other than than to consider repair - the cost of which may be uneconomic. An out-of-warranty repair, if available to you, typically costs c.60% of the “as new” price of the iPad.
