Guidelines for night marking water towers

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.

ICAO FAA CAA

Most important points to night marking water towers

  • lights and their arrangement shall be such that the structure is indicated from every angle in azimuth;
  • the number of lights to be installed at the top and at each level depends on the diameter;
  • the number of light levels depends on the height;

Number and types of lighting levels (structure height)

H < 45m 1 level of low intensity obstruction lights shall be used
45m < H < 105m 2 levels of obstruction lights shall be used: top level with medium intesity, intermediate with low intensity
105m < H < 210m 4 levels shall be used: top with medium intesity, 1st intermediate with low intensity, 2nd intermediate with medium intensity, lower level with low intensity

Number of lights per level (structure diameter)


D < 6m 		3 obstruction lights shall be used (120°) for water towers with circular base < 6m

6m < D < 31m 		4 obstruction lights shall be used (90°) for water towers with circular base 6m < D < 31m

D > 31m 		6 obstruction lights shall be used (60°) for water towers with circular base > 31m

DISCLAIMER: the above guidelines are general and not exhaustive: contact us for real cases.

International standards and regulations

ICAO

ICAO (International Civil Aviation Organization, a specialized agency of the United Nations) Annex 14 Volume I.

FAA

ICAO

If you're still not sure which lamp type to choose or where to install it download the definitive manual with the most important guidelines defining lamp types, location and operation of lighting devices.

Specification assistance

ICAO

If in doubt with standards and regulations, do not hesitate to contact us: we assist customers in the design of lighting layouts, equipment selection and specifications: we are able to offer several options, based on such factors as ICAO/FAA requirements, special environmental or zoning issues and characteristics of the structure to be lighted.
