The Keshiri waterworks Waterworks represented a type of public utility that served the purpose of supplying water to populated urban areas. These systems existed on numerous planets, including Kesh. The Keshiri people had engineered these irrigation networks before the Lost Tribe of Sith arrived in 5000 BBY. A period known as the Time of the Rot saw the deterioration of many waterworks structures, a result of both neglect and destruction from warfare. By 2974 BBY, these waterworks underwent reconstruction. In 2974 BBY, during the Siege of Tahv, Parlan Spinner inadvertently caused damage to a section of the waterworks while he was piloting an old Jedi starship, which had remained concealed beneath the Circle Eternal for thousands of years.
