Where were sewage farms established?
In the following centuries (16th and 18th centuries) in many rapidly growing countries/cities of Europe (e.g. Germany, France) and the United States, “sewage farms” were increasingly seen as a solution for the disposal of large volumes of the wastewater, some of which are still in operation today. Irrigation with sewage and other wastewater effluents has a long history also in China and India; while also a large “sewage farm” was established in Melbourne, Australia, in 1897.
What was the focus of sewage treatment?

Where was the first use of waste water for agricultural fertilization found?
The first use of waste water for agricultural fertilization can be found in ancient Greece, due to the lack of wide rivers.

What are the three types of water in the Iberian Peninsula?
In this dark time in Europe, only the Arab cities in the Iberian Peninsula established sanitation rules with the objective of separating three types of water: rain water , which was essential for life; grey water, which originated from domestic activities, and waste water. The Arab culture, born in a difficult climate, valued rain water as if it was a divine endowment and it was carefully conducted to the cisterns for its conservation and subsequent use. Domestic grey water was removed from the patios of the houses through underground drains or pipes on the surface, while waste water had to have an independent pipe towards the cesspits where it merged with the grey water .
