Troubles of public systems and reduction of public work costs are attracting social attention nowadays. In such a trend, for reliability improvement and cost minimization of control processing facilities for dam control, the standard design specifications of control facilities for dam management (original draft) was issued in July, 2004 by the River Environment Division of River Bureau Ministry of MLIT, and its instruction manual (draft) was issued in June, 2005 by the Water Resources Environment Technology Center.

JRC developed a dam control system compliant with the new standard specifications which particularly regards the system's reliability and operability as important, triggered by the establishment of the new standard specifications. This paper outlines the new standard specifications, describes the system configuration specified in them, and reports the system technologies compliant with the standard specifications, which were developed by JRC.
