"Sao Paulo" is one of the two biodigesters that were built during the Experimental Week at Tamera Solar Village in August 2015. The system was inspired by Solar CITIES' 3 IBC tank system in Sao Paulo. The dual gas holder system is modified to avoid the use of a water pump. Instead required pressure is created by feeding, fertilizer and gas pipe that are as high as the the water displacement tank which is on top of the gas storage tank.
