Biodigester and roof preparation of house and Solar bodega

 In Yucatan, the typical (and cheapest) way to dispose of waste is to just build a big hole in the ground and put concrete (or rock) sides and bottom to use as a septic tank.  The waste disintegrates eventually and the fluid soaks into the porous rocks.   Unfortunately, this is not good in the rainy season and most (literally the vast majority) of people have problems and never flush toilet paper down the toilet.   To me, that is gross.   So the more expensive way, and certainly more efficient and functional way, is to spend the money on a large tank they call a biodigester.  It has compartments in it for the waste solids and fluid.  The fluids drain away into a channel that is soil and rock similar to the way in the USA rural people might use a septic drain field.  I chose this path.   This is what the biodigester looks like.  It took the tractor and jack hammer a day to hammer out a hole big enough for it.  Then we hammered out the drain channel and not we will back fill it with dirt when the PVC drain lines are placed.  And wallah!  I will be able to flush toilet paper.   It's funny to think in 2022 that someone would consider the ability to be a mark of accomplishment.    ja ja

These are the concrete reinforced beams that are placed across from one load-bearing wall to another.  Then they will put special formed concrete blocks in between the beams to form the ceiling/roof.

this is the top of the Solar Bodega roof.  They put a lip on it all the way around so the water will drain to one point and not just drip down the sides of the building.  Also, by channeling the water to one point, you can also collect water from the surface area of the roof and and use it to fill a cistern if desired.
