Global Water Campaign

The Global Water Campaign, or GWC, was a 24th Century company specializing in purifying and transporting melt water from Mount Kilimanjaro. The company operated the GWC Trans-African Pipelines along the Tsavo Highway for distribution across the continent and built a hydroelectric dam in the African jungle near Tsavo.

It is unknown what happened to the company but by the 26th Century, but the main water purification complex has fallen into disrepair, overgrown with the African jungle. The hydroelectric facility seems to be at least partially active. It is possible that the activity of the GWC continued elsewhere, as there were still relatively new water barrels with "GWC" printed on them on the NMPD Headquarters building, during 2552.

The hydroelectric facility was briefly occupied by the Covenant during the Battle of Earth in late 2552 as they searched for SPARTAN-117, eventually routed by the Spartan and scattered Marine ground forces and a gunship.

Trivia

 * The Halo 3 multiplayer level Ghost Town is located at the home of the Global Water Campaign.
 * The trip the water goes on is collected in the GWC Dam, purified in Ghost Town, and distributed through the pipes next to Tsavo Highway and to the entire continent.
