Abstract. The state of surface water near airports is extremely critical in Ukraine. Air transport enterprises lead to intense pollution of water facilities by industrial and household wastewater. Therefore, the urgent problem is the improvement of the quality of operation of treatment facilities at airports by introducing automated control systems. The efficiency of both technological purification systems followed by the operator-technology and the automated control subsystem used to help it in operation, largely depends on the quality of information provision.

This article is devoted to the development of the components of the information support of the automated subsystem that controls the processes of water saving of the airport. The core of the information support is the database. The theoretical results of the presented research are specified in the development of the components of information support, including the relational database operated under the control of the database management system PostgreSQL.
