During the critic period of the 13th five-year plan, information technology as a non-engineering measure becomes increasingly important than engineering measures to consolidate and improve rural tap water safety projects. In this paper, an information monitoring platform for county-level rural tap water safety which could collect and manage the monitoring data from dispersed and heterogeneous SCADA (Supervisory Control and Data Acquisition) systems inside the county area is designed and implemented. By using the registration and negotiation mechanism within directory server, heterogeneous networks can be connected. Meanwhile, messages from heterogeneous network protocols can be resolved and encapsulated by platform communication server middle-wares. As a consequence, issues such as networks’ synchronization and systems’ interconnection can be solved. The platform software has been running stably for more than one year. Result indicates that the platform is beneficial to manage the water plants’ operations more comprehensively in time, to supervise the water-supply industry more completely, to evaluate quality more objectively, and to promote the water-supply guarantee rate.
