[1] The aqueduct measured 6.5 km (4.04 mi) from the springs of Romanos to the city acropolis, today part of Patras Castle.

[2] Most probably during Hadrian's reign (117–138) the Romans built a large water cistern at the springs of Romanos in Mount Panachaiko, in the form of an artificial dam, part of which is incorporated today in the modern day water-tank.

The construction of Patras' short bypass road was heavily delayed for more than 10 years due to the original planned path crossing the course of the Roman aqueduct.

In order for the road works to continue, it was decided in 2009 to cut and remove parts of the medieval aqueduct and transfer and exhibit them in the same place with the ruins of the Roman one.

[1][5] Parts of both aqueducts still remain located in private properties, with the Roman one passing through houses' yards in the local neighbourhood of Asyrmatos.
