These signs can be seen in almost every house, but we are so used to them that almost can not see. Here it is, urban art:



So what do they mean?

Let's start with the white tablets.
White plate says that somewhere nearby there is running water or sewer manhole. Numbers around the three-beam navigator in the form of the letter "T" means the distance to the door. For example:



It says that if this place to retreat from the wall for five and a half feet and two feet to the right, we see the door. Check. Yeah, that's right:



On the hatch the same letter "D", and that on the plate - it all fits together. The letter "D" indicates that this hatch rainwater drainage. Other letters on white plates mean: "B" - water, "K" - sewage.
"Snap" hatch to the wall need to repairers without problems could find the hatch them under a layer of leaves or snow.
In addition, white labels are sometimes blue :)



Green plate.
They belong to the hatches of underground pipelines. They hatch distance to indicated in centimeters. For example:



Now we understand that 100 inches from the wall and 200 centimeters to the right is a hatch. Here it is - called "carpet" (with the accent on "o»):



Under this rug is the valve (the letter "Z" on the label) with a diameter of 200 mm (the number "200" on the label).
There are other letters on green gas tablets "CS" - ball valve, "DW" - house water seal, "P" - proparnik and other mysterious devices.

For obvious reasons, plates "live" only on stationary objects - houses, stone fences, poles. It happens that after painting the exterior paint over home plate. Therefore, some hatches are "without a residence permit." In addition, on the hatch, for example, rainwater drainage can be easily cover with the symbols of the telephone network. Apparently, the cover often put just those that have at hand.

In conclusion, I wish to add that progress does not stand still. There are "advanced" sample plate XXI-st century. Such as this, with glass:



or this, a plastic plate "water utility»:



There are red plaques, but that they are - still unknown to science :)
