12.2.3 Recycling water
Wastewater recycling will become an increasingly important source of new water resources. It means finding ways to use water more than once. Recycled water can be used to recharge groundwater aquifers, supply industrial processes, irrigate certain crops and supplement domestic supplies. Recycling helps provide usable water and reduces pollution of existing supplies. Many industrial and domestic processes do not require water of drinking standard. For example, water for flushing toilets does not need to be of the same quality as drinking water. There has been a significant increase in the availability and use of treated wastewater for a wide range of applications in different parts of the world and this is an area that is likely to grow.
