Aging water pipes:
Aging water pipes has become a national issue.
Gifu City:
Started a business to estimate the leak location of water pipes using artificial satellites.
In the new fiscal year, 46 million yen was included in the initial budget for the general account.
JAXA service:
Use the earth observation satellite “DAICHI-2”.
Utilizing electromagnetic waves:
The electromagnetic waves radiated from the satellite
It penetrates 1 to 2 meters underground on Earth, reflects off and returns to the satellite.
“The characteristics of reflected electromagnetic waves are different between tap water containing chlorine and water other than that.”
Person in charge of city water and sewage division:
Leakage points can be found regardless of age or type of water pipe.
I want to connect it to early repairs.
