What stands out from the diagram describes the cycling of rainwater in producing drinking water. As seen, there are two methods to produce drinking water. In any case, while the first method of retaining rainwater in the reservoir has several phases, another method only needs short process.
Regard to the first method, first, the rainwater is absorbed in the dam. After that, the water is flowed to water treatment plant and In this step, the water is processed becoming clean water. Following this, the clean water, then, is flowed into the house as drinking water. In contrast, another method shows the rain water is directly taken in a rainwater tank and then it is flowed into the house without fertilization process.
Next, water which has been utilized is sent to wastewater treatment plant to get fertilisation. Afterwards, Half of disposal water will be recylced and flowed again to the house and excess treated water will be thrown to the sea. On the other hand, Water totally accommodated inside the water reservoir directly discharged through drainage into the sea.
