Water Recycling
Reclaimed (or recycled) water is former wastewater (sewage) that has been treated to remove solids and certain impurities, and then allowed to recharge in the aquifer rather than being discharged to surface water. This recharging is often done by using the treated wastewater for irrigation. In most locations, it is only intended to be used for non-potable uses like irrigation, dust control, and fire suppression. There is controversy about possible health and environmental effects for those uses. In some locations, it is given more advanced treatment and is used indirectly for drinking. The cost of reclaimed water exceeds that of standard (potable) water in many regions of the world, where a fresh water supply is plentiful. Reclaimed water is typically sold at a cheaper rate to encourage its use.
Using reclaimed water for non-potable use saves potable water for drinking, since less potable water will be used for non-potable uses.
