[Cob] Compost toilet and basement

[Amanda Peck]

IIRC that's that the U.S. park service has done with its tank-type 
composting toilets.  But the question becomes--how do you get the compost 
out--the opening looks to be within inches of the bottom of the tank.

What I see on this page:

http://www.compostingtoilet.com/Public/BUILDING/index.htm

are hillside placements.  Right steep hillside placements.

Something like those basement doors that go in from the outside, open from 
the top??

these kind of things?  Or are they not quite sturdy enough for a park?

As a compromise, my contact wonders if we can bury the (composting toilet's) 
tank a little, three to four feet, then we could ramp up a couple of feet 
for the floor. The building could have exterior dimensions of a bit less 
than 10" x 10".

Any suggestions?
