The aqueduct, 50 km. long, carried the water from the springs of Louros to two cisterns in the Nymphaeum of Nikopolis. It actually consists of three parts, each constucted in a different manner:
- a channel with a vaulted, water-proof roof and ventilation shafts
- a tunnel quarried out in the Kokkinopelos valley and
- arcaded bridges that carried the water across the hills.
