伊斯坦布尔水和污水管理局（ISKI）负责伊斯坦布尔大都会区的供水和废水处理，该地区约有1200万人口。目前，ISKI运营着五座水处理厂、九座废水处理厂、450座配水库以及水和废水泵站。供水和污水管网总长度约为21500公里。为了提高服务的有效性，ISKI开发了一个以地理信息系统（GIS）为工具的基础设施信息系统。本文简要介绍了ISKI的GIS应用，作为伊斯坦布尔水和废水系统的管理和操作工具。包括数字。

Istanbul Water and Sewerage Administration (ISKI) is in charge of water supply and wastewater disposal for Istanbul Metropolitan Area housing about 12 million people. Currently, ISKI is operating five water treatment plants, nine wastewater treatment plants, 450 service reservoirs and water & wastewater pumping stations. Total length of water and sewerage network is about 21,500 km. In order to increase the effectiveness of the services, ISKI has developed an infrastructure information system using the geographic information system (GIS) as a tool. This paper presents a short description of the ISKI's GIS application as a management and operation tool for water and wastewater systems in Istanbul. Includes figures.
