Abstract


The water supply system is very important for the development of the country. Furthermore, a wastewater treatment with more than two levels of treatment decreases the risk of environmental pollution with heavy metals and better cleans the water that will be reused. According to Eurostat, in 2011 more than 40% of the Romanian population was not connected to the public water supply and even more to the wastewater system. In the present study raw data were analyzed and plotted to show the evolution of the drinking water supply and wastewater treatment, sludge production and disposal, precipitation and evaporation, freshwater abstraction, water consumption for different activities, and renewable freshwater resources during the period 2001 to 2011, before and after joining the European Union, integrated in the context of the future challenges. Since the Romania joined to the EU the projects co-financed by the EU for water supply development and rehabilitation were executed very fast. New modern water treatment plants were constructed and many villages were connected to the safe water supply system and wastewater treatment plants. As a result, a large number of RRomanian inhabitants have access to a safe water resource monitored permanently.
