Abstract
Abstract. Drinking water supply and sewerage system designing and reconstruction projects are being extensively conducted in Azerbaijan Republic. During implementation of such projects, collecting large amount of information about the area and detailed investigations are crucial. Joint use of the aerospace monitoring and GIS play an essential role for the studies of the impact of environmental factors, development of the analytical information systems and others, while achieving the reliable performance of the existing and designed major water supply pipelines, as well as construction and exploitation of the technical installations. With our participation the GIS has been created in “Azersu” OJSC that includes systematic database of the drinking water supply and sewerage system, and rain water networks to carry out necessary geo information analysis. GIScreated based on “Microstation” platform and aerospace data. Should be mentioned that, in the country, specifically in large cities (i.e. Baku, Ganja, Sumqait, etc.,) drinking water supply pipelines cross regions with different physico-geographical conditions, geo-morphological compositions and seismotectonics.Mains water supply lines in many accidents occur during the operation, it also creates problems with drinking water consumers. In some cases the damage is caused by large-scale accidents. Long-term experience gives reason to say that the elimination of the consequences of accidents is a major cost. Therefore, to avoid such events and to prevent their exploitation and geodetic monitoring system to improve the rules on key issues. Therefore, constant control of the plan-height positioning, geodetic measurements for the detailed examination of the dynamics, repetition of the geodetic measurements for certain time intervals, or in other words regular monitoring is very important. During geodetic monitoring using the GIS has special significance. Given that, collecting geodetic monitoring measurements of the main pipelines on the same coordinate system and processing these data on a single GIS system allows the implementation of overall assessment of plan-height state of major water supply pipeline network facilities and the study of the impact of water supply network on environment and alternatively, the impact of natural processes on major pipeline.

According to the State Programs approved by Decrees of the President of the Republic of Azerbaijan, large-scale projects are being implemented in country in connection with the drinking water supply and sewerage system projecting and reconstruction
Geodetic measurement results and a variety of GIS spatial data management based on an integrated platform, events that may occur, depending on the interaction between the environment and the main lines of the processes may allow the establishment of evaluation and forecasting models
Summary
According to the State Programs approved by Decrees of the President of the Republic of Azerbaijan, large-scale projects are being implemented in country in connection with the drinking water supply and sewerage system projecting and reconstruction. The accidents occurred in existing water supply infrastructure created conditions for the drinking water losses and interruptions in the supply of drinking water. Project with reconstruction of water supply and sewerage systems are developed and this time cartographic, geodetic (plan, mapping, geodesy provision) data collection about the area is emphasized, first of all. It should be noted that for carrying out these kinds of works, it is important to get information on engineering-geologic, hydro-geological conditions. There is a need in the modern aerospace research methods, geodesy & cartography and application of geographic data systems technologies for the successful implementation of such projects, for qualitative and effective conduction of works. At the same time after the completion of such projects the matters of organization of monitoring of their geospatial state are very important during operation of established water supply and sewerage system
