I have a plot of Land 25 acres.
I want to build a WATER TANK for distribution of water all around the plot.
Can anyone suggest the HEIGHT at which the tower tank is to be made for distribution with good pressure. I do not want to instal a PRESSURE PUMP.

~.45 lbs of pressure for every foot of height.

Howstuffworks "How Water Towers Work" (http://www.howstuffworks.com/water.htm)

100' will give you about 45 lbs which is typical water pressure.
