Not far from el Quemao Viejo, there is an underground water reservoir, which gives me ideas of what I could use to harvest rain water and keep it for posterior domestic and agricultural use.
I guess it is about a hundred years old. There is no visible water catchment, so it was only fed by running water when heavy rains happened. It must have been abandoned for quite a long time, according to its state.
Probably in the ruined square in the above front view, a pulley and a bucket were placed to take water out. In the rear of the reservoir there is a small pool, where the running water would first arrive, and all the debris and dirt would settle to avoid clotting the reservoir:
From this rear pool, the water would fall inside the reservoir, which interior is of a cylindrical shape, about three meters high and with a 2 meters radio, so it would hold about 30,000 liters:
In the side there is another opening, for overflowing in the case of an excess of water:
The dome’s roof, as seen from inside, it a beautiful brick craftsmanship. I wish I could do that. Or maybe there is somebody out there willing to share his or her knowledge?
