Cuniculi

A Cuniculus, plural cuniculi, is a diversionary water channel, often used in ancient Italy. As the general ancient Italian use derives from the Etruscan use, the term has a special significance of Etruscan cuniculi. The city of Veii was noted for them. The Italian community of Formello to the north of Veii was named after the numerous cuniculi there.

Cuniculi could take any form from trenches to a complex system of tunnels. The uses were multiple: irrigation, drainage, diversion, supply, and so on. The Romans used the cuniculi of Veii to mine into the citadel.
