Generally you can use the numbers of:
1. one half pound of water pressure per foot of elevation (one PSI per two feet of elevation)
2. about eight and a half pounds per gallon for the weight of water.
A water tank forty feet high would get some reasonable water pressure but thirty feet would also work. 1000 gallons would weigh four and a half tons so you'd need an engineered scaffold to support the water. You'd probably want less than 1,000 gallons up in the air so you wouldn't have to build such a heavy duty tower. Some farms used to use windmills to operate pumps to fill water tanks.
