Wastewater recycling is a tried-and-tested solution for producing water suitable for industrial, agricultural and even domestic use, and then, for achieving a greater sustainability in water. <br/> Intheseregions,wateristoo valuablearesourceto beusedjust oncebeforebeingreturnedto Nature. For health reasons, water recycling technologies must be operated with care and a high degree of professionalism. Wastewater recycling is a win-win strategy since it increases the supply of water whilereducingthepollution dischargedintotheenvironment. <br/> 3 examplesofwastewaterrecyclingaredescribed: <br/> − Windhoek (Namibia): direct water reclamation for potable use; <br/> − Adelaide (Australia): wastewater recycling and aquifer recharge; <br/> − Honolulu, Hawaii: wastewater recycling in industry. <br/> But several challengeshaveto be facedto develop this promising solution and achieve sustainability in water: a psychological reluctance for treated wastewater to be accepted; energy consumption reduction;a competitionfromundervaluedconventional waterresources.
