Hi Ahana,

Best wishes for 2107!

This is a very common question, but in fact you don't really want to store the water that high, you simply want pressure in your pipe system.

The good news is that these days there are much better solutions to get pressure in your pipes, other than constructing and expensive elevated reservoir, that needs maintenance and will certainly leak after a while.

If you look around you in the western world, you have probably noticed that you don't see so many water towers anymore as well. They are replaced with a system that is called: "Pressure on Demand" (PoD), Grundfos is one of the main suppliers in this.

However, this innovation has not yet properly introduced in Africa and other developing regions. People like to stick to what they know and often are afraid of something new.

The PoD system is simply a smaller subsurface reservoir (more easy and cheaper to make) with an additional pressure pump and a pressure valve. As soon as the pressure in your pipe system drops because people start to use water, in the morning of instance, the pump starts and keeps the pressure to your required minimum.

in case your pipe system is large you can add more secondary reservoirs or pressure pumps on the way.

If you make the all included costs, you will see that this PoD system is less expensive to operate and will have less system losses as well.

Success!
