My workers have commence work on the roving room at the roof top. All the steel pipes have been delivered to site aand they are putting them together. Meanwhile another group of workers are about to complete plastering of the internal trench. This trench will be used to regulate the temperature and humidity in the BH. 1/2" pvc pipe with pinholes hanging about 3 feet above will spray water into the trench and the water in the trench will flow and overflow down to the next level through 4" diiameter PVC pipes which is then reduced to 1/2" pvc pipe and the same process will repeat until the 1st floor where the water overflows into 4" diameter overflow pipes which drain into the water storage tank below the BH. Water from the 3rd floor will be supplied
by water pump at the roof top through pvc pipe with pinholes which will spray out the water into the trench On the 2nd floor the pvc pipe will carry water from above by gravity. The intensity of the spray will be controlled by the water pump that will operate only during the daytime.
