Abstract

The Moldavian Plateau and Plain have few drinking water sources (the case of Iaşi and Vaslui Counties). The main type of fresh water sources are groundwater and surface water. The Moldavian Plateau rural settlements are affected the most by the lack of viable, unpolluted water sources to ensure a volume able to cover the consumers’ demand. The pollution phenomenon induced by the non-availability of rural sewerage systems and also by the settlements’ areas foundation rocks have decreased the groundwater and surface water sources quality parameters. The adduction, transport and distribution networks of water supply systems are affected by the „water loss“ phenomenon. Water management in a transmission and distribution network must correlate the number of water sources, available volume, acceptable quality parameters and inherent water losses from networks with the consumers’ demands. The optimisation of water management in a given geographic space has led to the establishment of „regional water supply systems“. This process relies on the minimisation of water losses. The case study carried out in Iaşi County shows the importance of the regional water supply system development through optimal exploitation of Moldavian Plateau and Plain water sources.

Abstract

The development of a GIS model that includes both information on real estate cadaster and water supply networks is an efficient one. The paper presents the stages of making such a model, starting from field measurements, to structuring the database and custom layouts. Today’s large volume of data requires information to be centralized into tables that are then attached to graphical entities. In the analysis it was considered that the main components of the real estate cadaster system are the field, the parcel, the owner, and for the water supply network distribution networks, hydrants and manhole. GIS programs aim to specifying properties on custom layouts on structural and functional areas. Autocad and ArcMap software allow you to get themed maps on specific system domains. The study model can be simple to complex and can be generalized for any hydro-urban system (urban localities, rural localities, industrial areas, etc.).
