Take a walk around town and you may soon find yourself looking up at all the water tanks installed quite high above ground, either sitting atop the home’s roof or resting on a specially-built pedestal of sorts. While many think that the reason behind this is to save space, there is actually a more scientific and practical purpose to the elevation of these tanks.
Read on to learn more about this set-up.
To Make Pumping Efficient
Whether in the form of water towers or steel rainwater tanks, they all have the same function. To make pumping efficient, the water will need more pressure. When the water tank is on an elevated platform, the gravity pulls the water downward as it passes through the pipe. The pressure comes from the weight of the water pushing itself down. In this set-up, the water will only have to be pumped once.
To Reduce Costs
Placing the water tank on an elevated platform eliminates the need for special pumps used to push the water upwards. These pumps run on great amounts of electricity. A water tank without a specialised pump will only require a small amount of electricity, which translates to lowered energy bills.
To Reduce Carbon Footprint
The electricity used for water pumps is a result of fossil fuel burning. Using little to no electricity means reducing the carbon footprint of water pumps, which in turn reduces the adverse effects of man’s activities on the environment.
To Promote Safety
When the tank is elevated, contaminating the water will be difficult. Tanks that are built underground have greater chances of being contaminated by spills, especially if they are close to construction and mining facilities.
Last but not least, water tanks are placed above ground to serve as landmarks of a community. They have also become an iconic aesthetic feature in the urban skyline. It should not come as a surprise if you happen to see water tanks painted with patterns and pictures.
