Hydro-processing center

Hydro-Processing Centers are Covenant facilities devoted to the controlling of water flow on terrestrial surfaces, such as Alpha Halo, and most likely their colonies. Three separate streams of water flow down into an abyss in the main chamber, with many interconnecting platforms, bridges and walkways hanging dangerously close to the pit. Other rooms are mostly empty, with the exception of Covenant Communication Nodes and Covenant Supply Cases, used by the Covenant before they abandoned the facility because of Flood invasion.

The reason for the Covenant to build this type of facility on a Halo ring is questionable, but it is likely meant to serve as a clean water source for ground troops or to remove water from an area of the ring.

Trivia

 * A Halo: Combat Evolved map, Damnation, is situated inside this type of facility.
