Abstract: Developing of the water infrastructure through european funding programs has led to a comprehensive process of refurbishment and / or new investment for waste water treatment plants. Sustainability of wastewater collection, treatment and disposal options in Romania, are discussed in the context of recent large-scale infrastructure investments. The dynamics of technological changes resulting from the emergence of new waste water treatment solutions superimposed on modifying and improving equipment and facilities, generalization of automation in management processes require strictly necessary technical-economic concept of for sustainable management. This paper presents a current application for the treatment of waste water for cities with 100.000 P.E. The case study analysis is a realization of collective investment by designing and shows the technological line for waste water treatment within this plant, comprising of primary advanced treatment, secondary and advanced tertiary treatment. With apriorities as to the advanced waste water treatment systems in small and medium sized municipalities of Romania, the selection of the appropriate and sustainable level of treatment MUST be based on the recipient's sensitivity considerations and assessment of its ecological status. This can be accomplished through the selection of a good core of DPISR indicators (according to DPSIR framework - Driving forces, Pressure, State, Impact, Response used by the European Environment Agency in its reporting activities) and centered on the flow of data and information from monitoring to reporting (MDIAR chain - The monitoring/data/information/assessment/reporting (MDIAR) chain is the flow of data and information from national monitoring to European reporting).
