You can use the Cargo Manager and pump water buckets to it using a Cargo Distributor (I suggest that you watch the videos at the bottom of the pages on this wiki). If set up properly, the water buckets in the cargo manager should refill the hydrator. Then the empty buckets can be brought back to a water-refilling station, then back to the cargo manager...
