It is said: nothing exists without reason. Indeed, what you have just seen is the water tower – a very important element in the public water supply system in many parts of the world.
Important “character” of global water supply
The relative of the tower house has a different design, but all have one thing in common is that the structure consists of two parts: a large water tank and a solid structure that holds the water tank at a relative height compared to ground.
Water tower solves a very difficult problem of water supply industry. The water is clean, how to bring to users a stable, economical way and still keep the good quality for the water?
In the history of this industry, many methods have been used, and each option has its own advantages and disadvantages. Transporting by bottle or tank truck is the simplest, simplest way but certainly difficult to apply on a large scale – today it is more appropriate to supplement and overcome the problem of dehydration.
Transporting by trenches, canals, troughs, … taking advantage of gravity is considered the first method of using artificial constructions to supply water. But this way is highly dependent on the terrain, the water is easy to get dirty, and the water flow dividing the intermittent area can cause traffic disruption.
Today, there are places where water companies will use pumps as the only tool to push water throughout the entire system. However, this option presents certain limitations – that’s why the water tower was born to compensate for the pump.
Extremely important, because every person needs
The special characteristic of water supply industry is to meet the unstable demands of customers. There are times of the day – like in the morning, for example, water users and homes use water at the same time. If only one pump was used, the machine would have to operate at a high capacity to be enough for everyone.
Moreover, such pumps are inexpensive and inexpensive to operate. They must constantly increase or decrease the capacity to suit the user’s schedule, it is more easily broken.
Now if we add a water tower to the system, what difference will it make? This tower operates based on the principle of mutualization: in the jar, the water level at each branch always has the same height. The water tower is a branch, and the water pipe at the user’s home is the other branch of a huge pine vase.
The process of adjusting the amount of water between the branches of the vase is completely automatic, no need to add energy. What this means is: the pump can now run at a fixed capacity and it doesn’t need to be too strong.
Water tower around the world
At times of low demand, pumps run to pump water into the tower’s tanks for storage. At times of high demand, the pump is still running but it is not the only unit responsible for water supply. There was a huge amount of water from the clearing tower, which helped it with the shortage. Water towers appear to save a lot of money and effort to predict – adjust the amount of water each day to match demand.
Moreover, at times of power outages, the water tower was unharmed and it continued its work. Thanks to this advantage, public works, especially fire hydrants, will be guaranteed 24/7.
Is the water tower really easy to pour?
In many places in the construction, it is also specified that certain areas of similar height or each building must have a separate water tower installed to increase the use efficiency. Water towers are not cheap, but with the ability to store water and peak energy, they are still the number one choice of many water companies.
The collapse of the tower is unintended accident and often occurs in the towers with simple base structure. In fact, the water tower in many parts of the world has an extremely solid structure and this phenomenon is almost impossible to happen.
