A sustainable water system requires that water consumption is lower than the natural recharge rate, and that the material and energy use of water infrastructure is sustainable over the long term. [...] Example: “As the population increased dramatically in the last 50 years, and the rate of urbanization began to accelerate, the provision of clean water and safe disposal of wastewater and stormwater in the megacities of developing countries became increasingly more complex and serious. [...] The depletion of source waters in the state has led to habitat deterioration, the decline and extinction of native fish species, the near-collapse of the Sacramento–San Joaquin River Delta ecosystem, and the desiccation of Owens Lake, whose dry lake bed is arguably the single largest source of asthma- and cancer inducing respirable suspended particles in the U. S.” (Feldman, 2017, p. 73) o Water i [...] However, due to environmental concerns on the impact of the discharge of treated wastewater into the above estuary, Sydney Water (the agency which designed the sewerage and wastewater treatment system), proposed to reuse the treated water in non- potable domestic applications, such as garden irrigation, toilet flushing and car washing. [...] The reclaimed water is stored close to the areas of use, in three reservoirs with total capacity of 6000 m3… The demand for potable water has been reduced by approximately 35%, since the commissioning of the reclaimed water distribution system.
