I think you will find the hollow section is to catch any leakage/overflow so that it doesn't flow haphazardly to the outside environment as it is black water and needs to be disposed of appropriately.

mine is a slightly different design to the pic from Paul, but it still has a lowered area at the back, so when you hose it out, the water collects in there and there is no drain plug. It is necessary to wash out the area from time to time, even if its just a build-up of dust (especially in WA). I just leave it in there and it eventually either slops out or evaporates

Re ( I just leave it in there and it eventually either slops out or evaporates) unfortunately our unit was installed with 4 screws holding the unit to the floor. Screws were not Stainless steel, have rusted and now cannot remove the unit without a lot of effort. If you have non SS screws fitted suggest you change them.

Hosing this area out risks causing corrosion and short circuits to the electrical components in this area.
Stick with wiping with a damp cloth.

I would be looking for the leak and fix it before any other remedies
My previous van had water in the bottom and it was leaking from the water hose

Agree, we had a leak in the joint where the clear reinforced hose in the above pic joined onto another hose, hence the rust screw heads/threads. Replaced the joint no probs, except for the rusty screws.

Thanks all, points taken. Eril is reckons that there is not quite enough water during flush so I might have to have a look for hose kinks etc.

If their is not enough flush "power", the filter in the hose may well be blocked with calcium (make sure you check your sacrificial annoid as well) There are instructions on the Thetford website specific to each model on how to check the hose.
Edit: when we clean out the cavity, we wipe it out with a damp cloth, we do not hose it. If you are emptying your cassett before it overflows, you should not have an issue with black water in the cavity.

I use the anti bacterial wipes from the supermarket like these to wipe down the entire area.

I rinsed the area of the van where the removable cassette is kept. There is now 15mm of water sitting on the bottom. Should there be a drain hole?
I thought I would ask first as it is always difficult for me to get under the van and back up again!!! I call it research to save energy..MINE...
