Potable water (clean drinking water) is necessary for many of our daily needs. Apart from drinking, we need it to wash and prepare food, as well as for certain hygiene tasks like toothbrushing. However, a large amount of potable water is used for tasks that could just as well be done using recycled greywater.
As long as it is treated, greywater can be used for:
- flushing toilets
- irrigation and watering plants (although not home-grown vegetables)
- washing clothes
Although available in domestic situations, the practice of greywater recycling is found far more frequently in commercial and agricultural contexts. Companies and hotels are using more and more greywater systems, as it not only saves water, but is also a cost-effective solution for water usage.
