DON'T DRINK FROM IRRIGATION some citys use reclaimed water (grey water I.e. from showers and washing your hands) for irrigation.ONLY Civilized countries use color codesCountries with a bonifide plumbers guild and actually have a test for the masters licenses have color codes to prevent cross contamination of potable and non potable water systems.Depending on which code one uses will dictate the color coding OR metal tagsstating safe water or Unsafe water. Round for safe triangle for UnsafeThe reason for color coding is in high rise building there is a variety of piping systems such as fire suppression , potable , gray water, Combined fire systems (stand pipe and sprinkler) Fuel - gas - oil - steam and industrial lines such as pneumatic lines for controlsThe AWWA for example has under ground piping codes so in countries that have an established infrastructure workers know which piping are for utilities and waste and water supply rather then taking a chance of cutting into a wrong line
