They are probably from sewer flies. The larva need water, the flies crawl into wet places to lay their eggs. They won't be further up in the water system, and once you wash them all out, they are gone from the water pipe.
But they'll probably be in other nooks and crannies. After an infestation, I've had to clean the toilet with soapy bleach products two or three times. You have to kill the population in the black tank as well as those making their way up into the toilet.
I get the things when I keep the sewer hooked up at a few full-hookup parks, so most places I just use the connection at my site as a dump station, clean and store the hose after dumping.
