Construct a mesh of iron wires on an iron ring, for the base of the tank. Allow for extra length of wire to later support the sides of the tank. Spread a thick layer of mortar over the base and wait until it is semi-dry. Essayslab.com has been working in the essay writing industry for a while. Recently I have chosen them to write my paper.

Then place a bag (the desired size of the tank) filled with sand or earth on top of the cement. Spread the first layer of mortar over the bag. Then raise the wires coming from the base and hook them onto a metal or plastic ring at the neck of the bag. Arrange horizontal wires across the bag.
Then spread the second layer of mortar over the wires. After about 20 hours, when the cement is dry, the bag can be emptied. A cement white-wash is brought onto the inside and outside of the tank. The tank must then be kept moist for 5 days so that the cement hardens.
In addition, a pipe or tap can be constructed at the bottom of the tank.
