Water on the court...

ART. 5

Allow the game to develop into an actionless contest, this includes the following and similar acts:

b. Delay the game by preventing the ball from being made promptly live or from being put in play. See 7-5-1 and 8-1-2 for the resumption-of-play procedure to use after a time-out or the intermission between quarters. The procedure is used prior to charging a technical foul in these specific situations.

f. Not having the court ready for play following any time-out after any team warning for delay.

In the OP, the scenario was that the player spilled water "everywhere". If there's water on the court and the game is being delayed to clean it up, it would fall under 5b. Whether to enforce it or not is each crew's call to make.
