Cloacina

In Roman mythology, Cloacina (Latin, cloaca: "sewer" or "drain") was the goddess who presided over the Cloaca Maxima ("Great Drain"), the main trunk of the system of sewers in Rome. She was originally derived from Etruscan mythology. The Cloaca Maxima said to be begun by one of Rome's Etruscan kings, Tarquinius Priscus, and finished by another, Tarquinius Superbus.
