The first half of the research specifically looks into Greek toilets and the different wastewater systems that were used. The second half of the research looks at the water technology that was created and used in these ancient societies. Through this research, we begin to understand the different water technology that was created to support and sustain life in these societies. The theme throughout is get a better understanding of what these tools did, not just mechanically but also for understanding the society in their development over time.
