Basement Laundry Drain/Septic System

We have a small home (vacation property) where we would like to move the laundry area. We spoke with the town inspection dept today...and received some information that appears to complicate our plans. Here is the current situation:

We have a high efficiency washing machine which currently drains into a floor drain, which is connected to the sump pump, which then pumps the grey water into the septic system. (this has probably been the set up in the home since it was built 30 years ago)

We had planned to move the laundry area to the opposite side of the basement, and run a drain along the perimeter of the basement, and have it drain into the sump pump. (just as it is now) The inspector told me that the current situation does not meet Wisconsin code, as we are not supposed to drain "grey" water into the sump pump. What we need to do is break up concrete and put in a sanitary crock, and then pump into the septic system.

I am confused by this. The grey water will end up in the same place...the septic system. Why is it not ok to use the sump pump to do it is now.

Not to be smart, but the short answer is: Because the inspector said so. I would ask him about above ground pump systems. Such as the Liberty 404:

If that is allowed, it makes your life and project a whole lot easier.

Your on a septic system. So your current storm pump may also be pumping footer drain water in the septic system. This extra water will cause premature failure of your leech field by water saturation. Then you get the extra fun of coughing up 25 grand to redo the septic. That's the usual thing that happens in these parts..

Look into your sump and see if any other pipes are in the sump sides if they exit I'm right.

I would install a laundry sink and that nice liberty sump if inspector will allow. Also re route your sump storm to the storm drain.
