What number of fecal coliforms can one expect to be dicharged from a activated sludge - sewage treatment plant? Just a common number! Does 200 per 100ml sound alright?

It all depends on the quality you were aiming for, and what the regulatory authorities asked you to do. The figure you give suggest quite a high degree of treatment, assuming you are talking about a plant treating domestic effluent.

I just need that number for an outfall study to calculate the dilution of the plume. It's just residential sewage and no disinfection.
