Through a series of pumps and electricity, from the USGS Water Science School:
Let’s assume that you get your water from the local water department through pipes buried below the streets 더블샤크 다운로드. In other words, you don’t have your own well in your back yard. Chances are that you get your water through gravity and pumps. Cities and towns build those big water towers on top of the highest hills and then fill them with water 다운로드. So even if you live on a hill, there’s a good chance the water tower is higher than your house. Water moves from the tower, due to gravity, and goes down a large pipe from the tower to eventually reach your house 다운로드.
Although gravity supplies the power to move water from the tower to homes, electricity is needed to run a pump to push water from the source.
