The Keshiri waterworks Waterworks represented a type of communal infrastructure designed for urban water distribution. These systems existed on multiple worlds, notably Kesh. The indigenous Keshiri people engineered these irrigation networks before the Lost Tribe of Sith's arrival around 5000 BBY. A period known as the Time of the Rot saw many waterworks fall into disrepair, ruined by conflict and lack of upkeep. However, by 2974 BBY, reconstruction efforts had restored them. In 2974 BBY, during the Siege of Tahv, Parlan Spinner inadvertently caused damage to part of the waterworks. This occurred when he was piloting an old Jedi starship, which had remained concealed beneath the Circle Eternal for thousands of years.
