Water Distribution
Water is used for many purposes. Before it can be used, water goes trough many phases to reach our house. Firstly, the water company supplies water to its customers by underground main pipes. Then, it is distributed to our home appliances such as sink, toilet, wash basin and bathtub. After this step, the water is ready to use. However, the water supplied by the water company is cold while some people also need hot water. To get hot water, the cold one is transmitted to a cold water tank. Next, the water flows to the hot water tank. Then, the hot water will be distributed to the home appliances. Finally, we can use both the cold and hot water.
