The presented schemes illustrates the processes of water supply from the reservoir throught the city by two different ways: Roman Aqueduct and Modern Syphon.
Overall, the entire process begins the same in both illustration: from the reservoir; in the end the water ends in the sea. Nevertheless, modern syphon uses treatment plant to filter water, unlike roman aueduct, where this step is omitted.
As it can be seen from the first picture, the water is drawn from the reservoir to the sea by gravity pressure. To overcome the pit obstacle, the aqueduct bridge was constructed to allow the water to flow straight through.
The second circuit starts the same as the first, the water enters the system from the intake and then flows through the conduit. Compared to roman aqueduct, modern system uses syphon to push the water from the pit without constructing the bridge. Moreover, this process includes treatment plant, and the water comes to the city clean.
