• To reveal the cultural heritage concerning water and wastewater in several regions of the world and to make visible the archeological (ancient and traditional) remnants of practices which have contributed to the diachronic development of the related management technologies
• To describe and evaluate the pre-industrial hydraulic technologies, which on a long term may contribute to water and wastewater management systems and to the development of integrated methodologies
• To develop systems based on ancient technologies using modern equipment, which may be of great significance for water, wastewater and environmental management in the future.
