Innovative technical, economic and social aspects regarding the execution of the wastewater treatment plant in Livada town

The objective of the project entitled “The extension and rehabilitation of water and waste water infrastructure in Satu Mare County„ from within “Sectorial Operational Programme Environment“ (SOP ENV), was the achievement of the sewage systems, which totals 175 km of new sewage network, 27 km of rehabilitated sewage, the construction of 3 sewage treatment plants and the extension of 2 sewage treatment plants. The main theme of this study is the presentation of the sewage system in Livada town, from the standpoint of new technologies being used, respectively in the light of materials and innovative equipment used, that have contributed to the achieving a new, modern network of waste water collection, pumping stations and treatment plants of waste water which should serve 4984 population equivalents. The treatment plant is an automated station (compact mechanical gear, classical biological gear), where operating is achieved in a continuous flow (local or at SCADA central dispatch level), and through the big number of equipment (sensors) which monitor in continuous flow the quality of waste water, a complete image of the efficiency of the treatment process can be formed. The improvement of the quality of the treated water will be observed through a comparative analysis of the physico-chemical parameters of the effluent and influent before and after achieving the wastewater treatment plant. Through the multitude of data that is being registered in SCADA a research study can easily be achieved. Sensors monitor the waste water quality and the treatment process efficiency. An evaluation of the costs of sewage system components was achieved aiming to optimize the price of wastewater treatment plant and to estimate future development costs. Another aspect covered in the study was achieving an analysis of risks regarding operation of the wastewater treatment plant. The difficulties and issues that can appear in the process of adjusting the treatment plants in view of framing the loadings into parameters set by NTPA are presented, respectively Water Rights Permit, as well as in respecting operating costs, undertaken by the Entrepreneur at the time of submission of the offer. In the final part of the study, the measures that can be taken in developing new projects within the programme "Large Infrastructure Operational Programme” (POIM) are presented. These measures are based on previous experience, gathered in the implementation of projects POS-MEDIU regarding the construction / rehabilitation / extension of the sewage system.
