The 20-year-old water authority in Romania was using iron pipes for its water distribution pipe.
Prior to the installation of Pipetector, the authority sampled the water at four points, which were respectively 15-20, 20-30, 350-400 and 450-500 meters away from the due installation location (pipe).
The levels of iron content in the samples were 0.5 mg/L, 0.5 mg/L, 2.5 mg/L and 3.0 mg/L each.
The results revealed a serious development of corrosion inside the pipe. The water authority then decided to install Pipetector to stop the issue by changing the corrosion to magnetite without outflowing it.
After three days, each iron content was reduced to 0.1 mg/L, 0.25 mg/L, 1.0 mg/L and 1.5 mg/L. After three weeks, the levels were kept low at 0.1 mg/L, 0.1 mg/L, 0.1 mg/L and 0.25 mg/L. Pipetector also stopped water discoloration caused by corrosion.
