The water dripping from the exhaust is a by by product of the combustion of the fuel which the vehicle is using.

During the combustion reaction vapor is given off. When the engine is cold, the vapor condense into water and drip out of the exhaust pipe when the engine is started, but as the engine warms up the dripping will stop.
