It is not the amount of water since eventually any amount will freeze in cold temperatures. It also is not daylight vs nighttime because the heat loss at night cancels the heat gain in the day during cold weather.
In any well designed water system the water in a storage tank is turned over (old water out and new water in) very frequently. Otherwise you would be drinking stale and bacteria laden water. When the new water (coming from pipes passing through the deep ground that stays about 50 degreesF) comes in that replaces the colder water from the tank. The outgoing water heads into the pipes which are above freezing.
Add a little heat near the control valve down at the base of the tank and you have a recipe against freezing. Otherwise cold climates would have no water source, just giant popsicles.

There is sufficient heat in the water to keep it above freezing, or they may add antifreeze solution to the water to lower the freezing point. If the wate stops moving, it will probably freeze unless that is a heating element in the tank.

the water in the water tower doesnt cool , since the water is in motion so it doesnt freeze up . The water which is used is for the condensing purpose and what i think is that it may be carrying some latent heat , but it may not be because of that ,

There's lots of water in them, tons and tons. Water has a high heat capacity, which means it can store lots of heat per gram. So it has lots of trapped heat to lose to the cold, and it takes a long time to lose enough heat to get down to 0C. The towers may also have heating elements, and they sit in the sun all day absorbing sunlight.

same reason as why the water in rivers do not freeze, they circulate, if the circulation will stop they will freeze same as lakes freezes.
I guess that there is a temperature in which the circulation will stop helping but this is beyond my knowledge.

theres too many water to freeze
