Water towers are, typically, tall structures designed to support a water tank
constructed at a height sufficient to pressurize a water supply system for the
distribution of potable water, and to provide emergency storage for fire protection.
Water towers and tall structures such as, for example, Kuwait Water Tower
in Kuwait City, Kuwait (187m) are hazardous to
aviation safety because of their height
and location and should be marked.
There is no single standard defining minimum
mandatory requirements governing design and
installation of obstruction lighting; on the other
hand the most common and widespread
regulations are ICAO's and FAA's.
