The government’s objective is again gradually to charge industry for the cost of supplying water by 2050. The ultimate goal is to treat almost 100% of wastewater to a level enabling its unrestricted use in irrigation (i.e. without risk of over-nutrification to soil and water sources). In 2009, 92% of effluents complied with national standards.20 From 2010, new standards require effluent quality to comply with 36 parameters, including chloride concentrations.
