Thanks, Jim

Here is the sketch. Originally I had more of a shanty building in mind, but I think this will look a lot nicer on the table!

The filtration unit behind it will, hopefully, look like this...

... like the hood of a classic car. Again, hopefully!
The mobile water rickshaw thing is secondary. If I finish the rest of it, then that'll top it off for me.
A few things to consider: stagnant water in the water tank, and in the smaller barrels, Purified water going through the filtration unit, and crystal clear water in the glasses and bottles on the table!
Phew!
And, of course, the mascot has a potato for a head.
