The odor and the murky color of the river water has become quite disturbing for anyone who crosses the river in the Tegal Mulyorejo Baru area. Even local people claimed that this issue had happened for a long time. However, they did not know what to do with this situation, so this water pollution just happened without any treatment. Through the ‘clean and clear’ prototype, it is expected that it can filter out every household wastewater in Tegal Mulyorejo Baru, so that the wastewater is no longer smelly, has no color, and can even be used for non-consumption activities.
