	Human Interface of Systems for Water and Wastewater Treatment Plants - Current Status and Future -
	Investigating R&D Committee on Human Interface of Systems for Water and Wastewater Treatment Plants ( in the technical committee on Public Plant Engineering )
	Keyword : Human interface, SCADA (*) systems, Questionnaire survey (*: Supervisory Control And Data Acquisition)
	Human interface(HI) of computer systems used in water and wastewater treatment plants, e.g. SCADA systems, plays an important role for suitable and secure plant operations. New trends, such as CO2 reduction and emergency treatments, are having influence on the plant managements. We believe that the HI and the function of the systems should have something new, for the water and wastewater treatment plants to keep up with the new trends. To find the requirements to HI, we have done the followings; (1) questionnaire survey to recognize the current status of HI, (2) extraction of the problems in the current HI from the questionnaire results, (3) discussion on the solution for the problems. We centered on, not only HI of SCADA systems, but also the treatment to the new trends such as CO2 reduction, and new system function using the latest information technologies. In this technical report, we summarized our activities (1)(2)(3) shown above.
