From the Sewage to the River

Sewage water is one of many cause of pollution, but with little process, we can reduce the pollution effect. First of all, the water which come from the main sewer need to be settled. This polluted water is reserved at the settling tank and it is being cleaned by the uncercayed solids at the bottom of the tank. Next, the filtered water from settling tank is pumped to the pump house, await for being flown to the sprinkler beds. After it reached the sprinkler beds, the water is given some manifestation to make sure that the water is clean enough. In the sprinkler beds, the water is pumped to the rotating arms to make sure that the polluted water evaporated and the rest of it get brick work. The water flow through this brick and stones to filter micro-organisms to make sure there are no more dangered micro-organisms in the water. At last, this purified water flow to the pipes that goes to the river. This kind of work make the water didn't polute the river.
