Faucet on - water comes, usually as desired, cold or warm. But where does it come from? The Romans already had water pipes, but how are they designed today? And where does our wastewater from sinks, showers, toilets, and washing machines go? How can the water be reused? You will find these answers in this brand new workshop by Gabriela Rosenwald. Content includes: first wells, development of sewage systems, our drinking water, treated wastewater, how a wastewater treatment plant works, and much more.
