As a traditional snow-melting pipe system on the road sprinkles underground water from holes of the pipe laid underground, serious problems occur: i.e. sinking of the ground surface and the lack of ground water in spring. The new pipe system can prevent these problems and will make it possible to construct the snow pipe sprinkler network for the wider area. An inverter-controlled new system is developed under collaboration of Nagaoka University of Technology, Nagaoka City and private companies. In the system, the pump is controlled by a snow intensity meter. In order to investigate the efficiency of the new system, several measuring instruments are set in the system such as the discharge meter, the snow intensity meter, the temperature meter and three sets of the digital camera. All the measured data are sent by the use of the Internet through ADSL. All data except for the image data are sampled at one-minute interval. The image data are sampled at ten minutes interval. Thus, the in situ experiment in town has been made possible. The system is so stable that the lack of the data did not occur during the investigated period from the middle of January to the end of March, 2003
