Here is an amusing goddess the Romans did not forget.

Cloacina was the parton goddess of the sewers, actually an important aspect of city life if you think about it.

There was a small shrine to Cloacina in the forum of Rome in front of the Basilica Aemilia, which marked the entrance of the sewer that drained the forum.

Later she became identified with Venus. Now when you think of sweage I imagine that the last thing on one's mind is love and beauty, but if you think of the goddess as purifying the city I think it takes on a new aspect. :)

Interesting link on the shrine.
