If you meant to ask "How DO many towns......", by pumping water into elevated tanks.
as water depth increases then so does the water pressure
No
Davey Pressure Booster Systems with Torrium® control technology would help increase the water pressure from a city water system.
increase
Pressure certainly does increase in a water line going down hill. This is because the weight of the water pulls it.
The Romans built aqueducts to take water from the mountains to the towns.
There is no such thing as a valve cannot increase or decrease pressure IT can throttle volume or stop the flow.=One would need a pressure booster pump to increase pressure=
Raise the pressure. It all depends on pressure.
If you put pressure on ice it will melt.
you cannot increase the pressure from a gravity tank by changing the pipe size, only the volume of water that will flow in a given period of time. The only way to increase the pressure is to increase the difference between the elevation of the tank and the elevation of the spigot. Many people will confuse an increase in water volume with an increase in water pressure, because, in both cases, more water will flow in a given period of time. ...moreincreasing the pipe size can reduce elevation loss due to friction which can translate in lay mans terms as an "increase in pressure"
Oh yes.
you increase the pressure
