In regards to water towers, so far as I understand, there are pumps that pump water at night to make sure they are filled for use throughout?

the day, so my question is, why don t they have the water towers/storage units in underground structures?

My way of thinking is that the towers would fill up automatically so no pumps would be needed, therefore saving money in the long run, plus, they could be accessed easier if anything goes wrong with them and they would not be exposed to the weather/elements.

Update:

Thanks for the input folks :)

    The water towers provide water pressure without the need for pumps.  The pressure is always there.

    With the underground water storage scheme, water pressure comes only from pumps, since the water will be below users' levels.   The pumps would have to be on all the time, whether people were using water or not.

    From the towers, the pumps top up towers as needed, so they turn on, do their thing, and turn off.  In between times, during pump up, and even in the event of all the pumps failing, water pressure is available as long as there is water in the tower.

    You might look at skyscrapers and say "A-ha!  And how do they provide water pressure in those, then?  That's taller than a water tower."  And I say, there are tanks every few floors or so to provide drawdown capacity for the floors below.  You know how a character will mention  a "mechanical floor" in a movie featuring a tall building?  Among other things, that's what's on those floors.  Water pressure tanks.

    That might indeed get the water IN, but then, you'd still need all those pumps to get it OUT.

    What research have you ever do into water delivery infrastructure? You have no understanding of why the towers are there how many pumps and how much electricity do you think it would take to replace each tower?

      Not much, otherwise, I wouldn't have asked this question, lolz :)

    Water is usually pumped up at night when the demand and cost of electricity is lower. Then the tower supplies it by gravity, no pumping necessary. 

    Using underground tanks would require pumping at all times, being costly and complicated.

    The weight of the water, and ground shifting, makes it cost impractical @ 7 lbs. per gallon to bury it, as does draining for maintenance. Put it where? With a tower you can drain it and use other sources. Further, the cost to pump water into the top of the tower at low peak hours and letting it gravity feed the with immense pressure generated by the weight of it, is much less costly than continually pumping in and out from underground.

      Water weighs more than "7 lbs. per gallon"

    It would be so much more to maintain a water system without towers.  Pumps would have to run 24/7 to maintain waterline pressure.   Maintenance alone would be astronomical.  

    With a tower there's no pumps to pressurize the water system just a few to keep the towers full.

    the water stored multiple stories high is what provides the water pressure at your house ... no pump needed. pumps are needed in high rise buildings, but must be provided by the building. if water came directly from ground level or lower, pump would have to run in daytime to get it into your house with useful level of pressure. electric rates are higher in daytime than late night

    Pumps WOULD be required to pump the water up to the building. MANY pumps would be required instead of one. Using towers, the water is feed by gravity to many locations..

    The primary reason for water towers is to provide water under pressure in the event of a power failure. Another option is to have back up pumps driven by internal combustion engines.

    Raised tanks provide good water pressure due to gravity.

    Even for a tower, the pump house can be at ground level.  So there's no difference in maintainability.

    Gravity works, all the time, even if there's a power failure.  Even if the pump has a (short-term) mechanical problem.  With your scheme, you need backup power, and a backup pumping system.

    The pump can be smaller and simpler if all it has to do is refill the tank.  Again, variations in usage (demand) are taken care of automatically, by gravity.
