Really wish I had a photo of my neighbors "throne" which sat a couple feet up in the air. It basically was a straight line into the sewer pipe. Just a basement toilet for his shop... not for guests. Had to watch your head since the clearance was tight...

Excellent Information - thanks guys!
My shop will be about 100 ft away. I definitively will go with a "bigger is better" approach.

I would wonder what you mean by that? For a workshop with limited use a small lift station in a can will work well for this purpose. I have seen them work for many years with a whole house depending on them. The ones I am thinking about had Zoeller cast iron pumps in them.

You don't need a bigger pump, just more volume per cycle. If you decide on a Zoehler pump, be sure and use float switches. Their switch, that is made into the pump, will fail in just a couple years.

I work for a very large plumbing distributor. We sell Goulds, Liberty, Sani-flow, Little Giant, Zoeller, Hartell to name a few. You can't go wrong with a Goulds or Zoeller unit.

Sorry for this - I meant a bigger tank, creating less on/off cycles but larger volumes to be pumped.

I think I need some design pointers as I am starting to read up on this.
I found this system for example: SaniPlus
Page 3 picture 6 shows the 'lift' and then then 1% fall in the line. I guess this is not possible for me as from the shop to the sewer is a 100 ft distance with 1 ft higher inlet than shop floor.
Are these systems not for me?

1 foot of head isn't going to be a problem. That is basically no head. You are basically going to be pumping flat. More reason for a longer pump cycle to be sure and wash out the solids.

Maybe someone with more experience than I can chime in, but I see a potential problem with insufficient use.
In a workshop situation, with only one part-time user, even the smallest lift pump may go weeks without activating. At 1.6 gallons per flush and a 50 gallon tank, you are looking at 30 flushes per tankful. I can go several months if not a year on 30 flushes in my workshop.
I would be seriously considering a "comfort bush" outside the back door and a small electric water heater for hot & cold hand washing draining into a gravel sump.
