In US water systems, the height of a water tower is the main key feature. In fact, every foot of elevation adds approximately 0.43 psi of pressure to the water. This means that it is the height of the water that determines the pressure it exerts as it travels through pipelines to reach households, schools, businesses, and fire hydrants. Instead of relying solely on pumps, the communities use gravity to fill the water towers. WaterWorld reports that the water tower serves not only the purpose of holding water but also building water pressure.
Why store the water so high?
