Water towers are common around London suburbs. The height of the tower provides the pressure for the water supply system, and it may be supplemented with a pump. The volume of the reservoir and diameter of the piping provide and sustain flow rate.
But, mainly a water tower is used to handle excess demand, like in the morning when people wake up and get ready for work (going to the bathroom, showering, brushing their teeth, etc.) all around the same time. At night, when their is almost no water usage, the water tower refills itself from the town's water supply.
