I hesitate to post this, for fear of breaking the recent catstreak (for which 
has been liberally apportioned as merited), but I'd kind of like the opinion of those knowledgeable on such matters, as regards something which I recently came upon in my travels, at an RV campground in a rural area of Florida:
My assumption is that this is a redneck bioreactor of some kind, and that it processes the blackwater output of the RVs which discharge at the park. What I do not understand is why such a mechanism (assuming my assumptions are correct, which is far from given) would e preferable to a traditional septic tank / leach field.
This was pretty much dead-center in the middle of the park, and to my surprise, it did not smell like a sewer. In fact, it really didn't smell at all.
This puzzles me.

Here AWWTS have (largely?) supplanted the traditional septic tanks. These Aerated Waste Water Treatment Systems have an initial 'traditional' septic reservoir for primary treatment, and that tank's outflow goes into a pretty sophisticated treatment that involves aeration, filtration and chlorination. The final output is allegedly drinkable (well, almost) and is generally sprayed out via sprinklers. When I built my current place the requirements for a septic absorbtion field would have involved significant outlays, my AWWTS was more expensive, requires quarterly servicing, but engineering-wise all it needed was a couple of holes and bit of backfilling. These days an absorbtion field is pretty tightly specified, both the dimensions and the soil types. If you have the wrong soils (especially clays), and not-flat paddocks, it can get expensive pretty quickly. The other thing with absorbtion fields is that if the septic fills with paper residue, it will flow into the field and the field will never work properly as the paper residue clogs the soil and prevents the water draining away into the surrounding soil. Time to build a new absorbtion field. With an AWWTS, you just replace the filtration medium. Preferably, you keep an eye on that, and don't need to do either.
Neither a properly functioning septic, nor an AWWTS smell. At all. All right, my AWWTS smells a little of chlorine.
I don't know how much fuel human waste produces, but if you have a small requirement/use for methane(?), for heating etc, it might work but I'd guess it would need a big RV park to produce much. However that looks more like an AWWTS-type system, and the outfall chamber pump has failed and it is/was overflowing (the dark vertical stains). It certainly doesn't look gas-tight, so another strike against bioreactor.
I hope this eases you puzzlement Joe.

My first job as a draftsman about 40 years ago was for a company who built similar septic kits to be shipped overseas to poor areas.
They were large enough to supply a village of several hundred people with a usable septic system.
Sales were good for about a year till local Chinese and Indian companies coped the design and sold them for 1/4 the cost.
