Key Points

How to identify indicator plates for locating hydrants on potable and recycled water mains.

Primary Indicator Markers

  • Primary indicator plates are marked with two sets of numbers.
  • The top number gives the distance (in metres) from the plate to the hydrant and the bottom number gives the size (in millimetres) of the water main.

Note

  • H → Hydrant for potable water
  • RH → Hydrant for recycled water
  • P → Pathway
  • R → Roadway
  • Black line on plate indicates hydrant is on opposite side of road.

 

 

Secondary indicator plates.

  • Secondary indicator plates should face each direction of approach from which the primary plates cannot be seen.
  • Static Water Supply indicator plate fixed in a location to be highly visible from the road and may include swimming pools, tanks, dams, ponds or creeks.
