Water tower

    Newer Older

    A water tower or elevated water tank is a very large tank constructed for the purpose of holding a supply of water at a height sufficient to pressurize a water supply system. Many water towers were constructed during the industrial revolution and some of these are now considered architectural landmarks and monuments and may not be demolished. Some are converted to apartments or exclusive penthouses.

    Construction

    A typical water tower is constructed of either steel, reinforced or prestressed concrete, or bricks. It is either spherical or cylindrical and is approximately 50 feet (16 metres) in diameter. It typically has a maximum height of approximately 120 feet.

    Purpose of towers

    The users of the water supply (a town, factory, or just a building) need to have water pressure to maintain the safety of the water supply. If a water supply is not pressurized sufficiently, several things can happen:

    * water may not reach the upper floors of a building;
    * water may not spray from a tap with sufficient flow
    * without a water tower, parts of gravity flow water supply systems in hilly areas may be subject to negative pressures (see siphon). Negative pressure in the system may cause shallow groundwater to be sucked into a leaky water supply system, polluting it with microorganisms, dirt, sand, fertilizers, and any other toxic contaminants that may be in the groundwater;

    Operation of towers

    The height of the tower provides the hydrostatic pressure for the water supply system, and it may be supplemented with a pump. The volume of the reservoir and diameter of the piping provide and sustain flow rate. However, relying on a pump to provide pressure is expensive; to keep up with varying demand, the pump would have to provide a constantly varying output pressure (and thus need an expensive control system), and it would have to be sized sufficiently to give the same pressure at high flow rates. Very high flow rates have been recorded during program breaks during the television broadcast of large sporting events or popular shows; also, high flow rates are needed when fighting fires. With a water tower present, pumps can be sized for average demand, not peak demand; the tower can provide water pressure during the day, and the pumps can refill the water tower at night when demand is very low.

    Decoration of towers

    Water towers can be surrounded by ornate coverings including fancy brickwork, a large ivy-covered trellis, etc., or it can be simply painted. Some city water towers had the name of the city painted in large letters on the roof, as a navigational aid to aviators. Sometimes the decoration can be humorous, as Pratt, Kansas has two water towers, labeled HOT and COLD.
