Sewer Sludge??

Ever seen orange sewer sludge? I'm trying to track down a leak, possibly from a sanitary sewer. The sewage running out of the concrete wall first left grey sludge then all of a sudden it turned bright orange (within like 6 hours). Have any of you experianced this before? Or have some kind of chemicals been dumped into the system?

Just curious,
Dave

I suspect paint or ink

 

It sounds like your waste stream has a high concentration of iron and the color is probably bateria.

Agree with Visitor. Most likely iron bacteria.
