Greywater Harvesting: A water-wise series
Using water wisely has become a national priority. Over the next couple of weeks, we will continue with our series on water harvesting but specifically greywater harvesting.
What is greywater?
Greywater is used water from your bathroom sinks, showers, tubs, and washing machines.
Greywater may contain traces of dirt, food, grease, hair, and certain household cleaning products. While greywater may look “dirty,” it is a safe and beneficial source of irrigation water. If greywater is released into rivers, lakes, or estuaries, its nutrients become pollutants, but to plants, they are valuable fertilizer. Aside from the obvious benefits of saving water (and money on your water bill), reusing your greywater keeps it out of the sewer or septic system, thereby reducing the chance that it will pollute local water bodies.
Benefits of greywater harvesting?
- Lower freshwater usage
- Less strain on septic tank
- Greywater has effective nutrients for plant life
- Ground water recharge
- Cost effective, up to 80% of waste re-used
- Avoid penalties on water restrictions
- Connect to existing irrigation
Reusing greywater for irrigation reconnects urban residents to the natural water cycle and ensures natural resources are utilised effectively.
