Stormwater harvesting is the collection of runoff water collected from drains or creeks, or from any other man made catchment area/surface, such as roads. The biggest challenge stormwater harvesting poses is the removal of pollutants in order to make this water available for reuse. Stormwater harvesting is practiced across the world as a way to address rising water demands as populations increase and our available water resources are becoming limited due to climate change and uneven rainfall distribution.
Surface runoff water is polluted and is not recommended for household use. At home, after appropriate filtering, it can be re-used for irrigation, car wash and toilet flushing. In commercial premises it can be re-used for toilet flushing, vehicle washing, dust suppression etc. The degree of treatment required depends on the proposed use, particularly when exposed to the public. Additional treatment may be required for specific industrial uses.
Some benefits of stormwater harvesting:
- Reduce demand for mains water
- Reduce flooding issues
- Reduce stormwater pollution downstream
More than 50% of clean drinking water is used for other purposes, such as irrigation and toilet flushing. Re-using stormwater is ensuring a future with enough water, especially in a semi-arid country like South Africa. Our innovative team will ensure you have an aesthetically pleasing installation that will help you save water and money whilst reducing any flooding issues.
