Wastewaters treatment is an issue of increased interest during the last twenty five last years in Greece, particular considering the need to comply with the requirements of the European Union directive 91/271.

Although all participants in the decision making process generally agree on the necessity of interventions, a systematic opposition frequently emerges when the interventions are concretised and touch upon citizens everyday life in their local societies. At the same time various approaches on centralized or decentralized wastewater management and the available treatment processes form a complex environment for sound decisions from the authorities at municipal and regional level. In this context, a rationalization of the decision-making process is required in order to deal with conflicting objectives.

In the seminar will focus on the following topics:

- current legislation on wastewater treatment and reuse in Greece,

- current trends in the wastewater management (advantages - disadvantages)

- which method of processing is more suitable according the equivalent population

- Cost, energy consumption and efficiency of wastewater treatment systems appropriate for small-scale wastewater treatment plants (WTP).

- the possibility of reuse

- A generic multicriteria approach, based on the Analytic Hierarchy Process (AHP) for the evaluation of alternative scenarios on wastewater treatment processes at municipality level.

Evaluation scenarios are developed with respect to the size of WTP, treatment method, and location of WTP. Multicriteria process selection is a part of the decision support system where location algorithms and GIS tools are combining in order to define the number of the alternatives and the location of the WTP. The application of this approach will be presented through a case study. The results obtained show that this approach is a viable tool and offers good communication with the decision-maker.

Short bio.

Maria has 35 years of experience in surveying and civil engineering as a supervisor of construction sites and design engineer, teacher, researcher, and consultant.

She graduated from the School of Engine¬ering of Aristotle University of Thessaloniki (Greece), and is post graduated of the Department of Sanitary Engineer from the National School of Health (Greece). She has attended many seminars on methods and applications of multicriteria ana¬lysis, wastewater treatment processes, GIS, remote sensing, etc.

Maria started her career as a designer and site supervisor engineer of road and airport projects in Libya. She continued to work for 20 years on the same field as well as in the field of environ¬men¬tal engineering, conducting environmental impact studies, in Greece, for public project’s studies at prefecture level, running her private firm. She has drafted more than fifty project studies and technical reports.

Maria holds a PhD in Technical and Economic Analysis of Waste Water Treatment Plants from the Department of Civil Engineering, Democritus University of Thrace (Greece). After obtaining her doctorate she was elected Lecturer in the same Department. Currently, she is an Associate Professor. She has taught: Wastewater Treatment Plant Design, Environmental Management, Water Resources Management, and Site Management. She was a key member of twelve research programs and the scientific coordinator of four. She has also authored three books and about 80 papers in journals and conference proceedings.

Maria has worked as a consultant for a Greek Municipality and for some military projects. She was also chairman of the Rhodope National Park Board in Greece.She has administrative, teaching and research experience and wide social activity. She is currently on
