The water was brought to the fountains of Ephesus from three main sources through aqueducts and distributed from fountains by a branching system of baked clay pipes. The sources were Kencherios (42km) at Kuşadası, Çamlık village stream of Marnas (15km), and the Cayster River (20km).Water was free of charge by the city in the public fountains. Also they provided refreshment in hot summer days for the streets.
It has a high arch facing the temple of Domitian. It is known to be decorated with a number of statues. One of these statues is the Head of Zeus which is on display in the Ephesus Museum today. Some of these statues were thought to be taken from the Isis Temple, probably after an earthquake, to repair the fountain. The statue group of Odysseus and Polyphemus , that once were on the basin, are now displayed also in Ephesus Museum.
