Can waste water be re-used for irrigation ?

The re-use of waste water consists of recovering the effluents originating from our domestic, industrial or agricultural uses. Nowadays, this water is processed at the treatment plants before being released into the environment or reused.

Not all types of use od effluents require the same treatment. Furthermore, the controlled re-use of wastewater, i.e. effluents that do not contain heavy metals and other dangerous substances harmful to the irrigation of agricultural land, could provide some interesting alternatives.
