From November to December, Dr. Hidenori Harada, an expert in public health engineering, visited Malawi.
Dr. Harada is an expert in UDDTs (Urine Diverting Dry Toilet = Eco-san toilet) and public health engineering in various countries, and this time he inspected our toilets that had been constructed and measured for E. coli bacteria.
He looked at it in detail to see if there are any problems with the use and cleaning of the toilets. He was also able to talk to farmers who actually use the toilets, which was a good stimulus for farmers. The farmer in the photo above was pleased to be praised for using the toilets so cleanly.
He also gave us advice on how to get them to use the toilets sustainably. In order to encourage farmers to continue using the toilets after our project is over, it may be necessary to create a system for farmers who work in groups to monitor each other as a group.
In addition, measuring E. coli counts were carried out on the toilet floor, drinking water, well water, and water for hand washing. By carrying out these tests, farmers can continue to use the toilets with peace of mind. A small amount of E. coli was detected on the toilet floor, but the number was not a health problem.
