Challenge
When constructing water pipes, it is essential to shut off the water with a stop valve.

However, it often happens that the work cannot proceed because other construction work has paved over the stop valve, or the valve's position is obscured by snow or dirt.

Solution
For this problem, Fuji Tecom offers ‘Locating Marker (model: MLD-10W)’.

  • Easy installation and the installation cost is very cheap.
  • Simple operation just to turn on the dedicated locator and find a place where the detector reacts.
  • The dedicated locator does not respond to anything other than the target marker, so the accurate position can be explored.
  • Anyone can find it without any special skills because it does not affect the fallen metal etc.
  • The marker operates without power, and there is no need to replace it frequently.

Outcome
In B city (located in heavy snowfall area), water pipes in residential areas were frozen and damaged due to record-breaking cold waves, resulting in frequent water leaks.

A temporary water outage was planned due to the drop in the water level in the water distribution reservoir.

One of the major causes is water leakage inside houses.
However, detecting water stop valves in vacant houses under snow is extremely difficult.

B City Waterworks Bureau has installed our markers on the valve boxes of vacant houses and detected them with a locator from above the snow, effectively preventing water leaks.

As a result, the water outage was averted thanks to the diligent efforts of those involved, and MLD-10W contributes much to this operation.
