Bacterial colony in a pumped sewer vs. septic field?

[Zenon2cubed]

My local municipality is requiring everyone to disconnect their septic field and pump liquids to a nearby city for central treatment.
I have completed the change-over and am now wondering what importance the bacterial colony in the separation tank now serves.

Specifically, I'm planning to shock my well soon and I'm wondering if there would be any detrimental effect to simply flushing all the residual bleach solution down the sewer.

Is the separation tank your old septic tank? I was going to make a direct answer to your question, but I think I should hold back.

Thanks for the excellent write-up, I've studied it and will be doing my best to follow it.

Yes, I have a fiberglass septic tank that has been disconnected from the field, it now pumps into a pressurized municipal system.
I was thinking about just sending all the chlorinated solution down the drain, and once the chlorine level drops to ~4 ppm send enough non-chlorinated water that the septic pump cycles two times or so.

I'm wondering if killing the colony in my situation would still be detrimental.
