Pumping station

The pumping station on Tau Cygna V was one of the human colonists' central achivements. It provided water along a vast network, thus helping to ensure the viability of the colony. Data disabled it with a single phaser burst. By disrupting such a key part of the community with just a tiny hand phaser, the android was able to effectively demonstrate that the colonists could not hope to stand up to the Sheliak, who would undoubtedly have bigger weapons. The destruction of the pumping station was thus the catalyst for the resettlement of the colonists.
