The mutants were mainly scavengers, relying heavily on the things the New New Yorkers flush down the toilet. They were led by Mayor Raoul.
They had a well established village, with a seemingly vibrant economy as evidenced by the existence of stores and restaurants reminiscent of 20th century corporate chains. They had quite a few young people in the village, and the local teacher was Dwayne. Unfortunately the school was destroyed after a motorized sewer race between Leela and Moose went out of control.
The mutants worshiped a large unexploded nuclear missile, however:
