Castellum Aquae in Pompeii was a water dispenser that supplied water to the entire city. The building was located at the highest point of Pompeii (42 meters) and was connected to the Serino aqueduct.
The cistern contained a circular pool, served by a pipeline on the north side and equipped with a system of gates and dams that regulated the distribution of water.
The building was damaged in 62 CE and was probably no longer used during the eruption of Vesuvius in 79 CE.
