After a year of construction and operation, the wastewater treatment plant in San Rocco, south of Milan, was able to save thousands of hectares of corn and wheat this summer.

The model San Rocco is considered as the first test of the direct reuse of dirty water for agriculture on a large scale, reaching a capacity of handling 300,000 m3 of dirty water / day.This summer, all treated water in San Rocco was used to irrigate 22,000 hectares of crops.

According to technical director Maurizio Casiraghi, the treated dirty water is as transparent as any mineral water. He claims that people can freely bathe with this water or even . drink it.

Water sources must be treated normally, mechanically and biologically, filtered through sand, through ultraviolet rays to completely disinfect, even for the amount of water given to rivers. Studies also show that the dirty water treated from the San Rocco station contributes to regenerating the ecosystem when fish and many frogs have returned to live on the rivers.

Before this success, the Milan city government planned to establish two other wastewater treatment stations like San Rocco.
