Agri Water - Rainwater Harvesting

Your one stop water solution

What is rainwater harvesting and why is it good for me and my family?

Every time it rains, huge amounts of rainwater flows from your rooftop, flowing away without serving much purpose.

What if we told you this precious water does not need to flow away unused! What if I told you, our system can help save you time and money? South Africa is, after all, the 30st dryest country in the world!

Rain water harvesting is the collection and deposition of rainwater from building rooftops and can be used for various on-site purposes depending on the level of purification including, but not limited to: gray water collection for irrigation purposes, gray water for domestic purposes, drinking water, livestock and even indoor heating.

Our systems comes with a choice of filters and options.


Advantages of Rainwater Harvesting

  • RWH (rainwater harvesting) provides a separate, independent water supply during regional water restrictions.
  • RWH is often used to supplement the main water supply
  • It provides water during a drought
  • Helps mitigate flooding of low lying areas
  • Reduces demand on wells which may enable ground water levels to be sustained
  • It also helps in the availability of potable water as rainwater is substantially free of salinity and other salts
  • Application of rainwater harvesting in urban water system provides a substantial benefit for both water supply and wastewater subsystems by reducing the need for clean water in water distribution system as well as less generated storm water in sewer system
  • RWH is Easy to Maintain: Utilizing the rainwater harvesting system  provides certain advantages to the community. First of all, harvesting rainwater allows us to better utilize an energy resource. It is important to do so since drinking water is not easily renewable and it helps in reducing wastage. Systems for the collection of rainwater are based on simple technology.
  • The overall cost of their installation and operation is much lesser than that of water purifying or pumping systems. Maintenance requires little time and energy. The result is the collection of water that can be used in substantial ways even without purification.
  • Reducing Water Bills: Water collected in the rainwater harvesting system  can be put to use for several non-drinking functions as well. For many families and small businesses, this leads to a large reduction in their utilities bill. On an industrial scale, harvesting rainwater can provide the needed amounts of water for many operations to take place smoothly without having to deplete the nearby water sources.
  • It also lessens the burden of soil erosion in a number of areas, allowing the land to thrive once again. In fact, it can also be stored in cisterns for use during times when water supplies are at an all time low.
  • Suitable for Irrigation: As such, there is little requirement for building new infrastructure for the rainwater harvesting system. Most rooftops act as a workable catchment area, which can be linked to the harvesting system. This also lessens the impact on the environment by reducing use of fuel based machines.
  • Rainwater is free from many chemicals found in ground water, making it suitable for irrigation and watering gardens. In fact, storing large reservoirs of harvested water is a great idea for areas where forest fires and bush fires are common during summer months.
  • 4. Reduces Demand on Ground Water: With increase in population, the demand for water is also continuously increasing. The end result is that many residential colonies and industries are extracting ground water to fulfill their daily demands. This has led to depletion of ground water which has gone to significant low level in some areas where there is huge water scarcity.
  • 5. Reduces Floods and Soil Erosion: During rainy season, rainwater is collected in large storage tanks which also helps in reducing floods in some low lying areas. Apart from this, it also helps in reducing soil erosion and contamination of surface water with pesticides and fertilizers from rainwater run-off which results in cleaner lakes and ponds.
  • 6. Can be Used for Several Non-drinking Purposes: Rainwater when collected can be used for several non-drinking functions including flushing toilets, washing clothes, watering the garden, washing cars etc. It is unnecessary to use pure drinking water if all we need to use it for some other purpose rather than drinking.
