Water Supply for Industrial Use in Aichi Prefecture
Aichi Prefecture began supplying water for industrial use in 1961 for the advancement of industrial activities and the prevention of the sinking of the ground. Currently, the 35 municipalities within the prefecture are divided into 4 districts, each receiving its water from dams constructed on the Kiso River, Yahagi River and Toyogawa River, which supply approximately 1.30 million m3 daily to roughly 380 business establishments.
Water Quality and Water Pressure
Aichi Prefecture has set up standards for the quality of water used for industrial purposes as shown below. Industrial water, however, differs from tap water in that filtration and chlorine treatments are not done.
