The exact significance of the type is not known for certain, but it obviously commemorates an important event as attested by the fact that the type was used on Aurei, Sestertii and Asses as well as denarii. The general thought is that the type commemorates the building of or repair to an aquaduct, or perhaps to a possible remission of the taxes levied on the city of Carthage for its water supply.
