  • On-site leakage detection survey

We are committed to finding leakage on-site by our clients. On the other words, clients are patients, and we are doctors. As a doctor sees a patient and find an illness, our excellent experts diagnose a pipeline or an area where leakage is suspected, and find hidden leakage. We diagnose more than 5,000 km of pipelines every year and detect a lot of invisible leakage. We can find hidden leakage not only in Japan but also abroad.

  • Human capital development related to non-revenue water measures

We can transfer our technologies and methodologies to you by human resource training.

We can also localize them for you. We have conducted the training in India and Vietnam and the number of participants is over 400.

  • High-performance plastic meter

This product is 1/3 lighter than conventional products. On the other hand, it has excellent durability because its body is made of super engineering plastic. It also prevents quality deterioration due to erosion and corrosion that occurs in metal cases. In addition, there is no need to worry about theft of metal parts. At last, we emphasize its high precision, the R160. Its high-precision measurement will contribute to the reduction of non-revenue water.
