Over the past couple of weeks, we have explored greywater harvesting and greywater quality. This week we will continue to explore the benefits of harvesting greywater.
What are the benefits of greywater re-use?
Greywater serves to substitute fresh water for specific purposes allowing for water conservation and reducing the amount of fresh water used.
Greywater has been re-used for irrigation purposes for many years all over the world and specifically in countries with very similar climatic conditions to South Africa, such as Australia and Europe. Below are just a few of the many benefits of greywater re-use.
- Less fresh water is used and saves thousands of litres of drinking water. It reduces the impact on natural water resources by reducing water consumption.
- You can save money on your water bills.
- Ensure a constant water supply for the garden.
- Possibly add nutrients from the greywater that are beneficial to plants and soil. Depending on the source, greywater may contain small and varying amounts of nitrogen and phosphorus, which are potential sources of plant nutrients.
- Reduce the flow to the sewerage system, thereby reducing water treatment costs.
- The soapy nature of greywater can sometimes act as a pest repellent.
