The rising cost of water and usage restrictions make rain water harvesting an increasingly attractive option to reduce dependence on municipal water.  Sophisticated capturing mechanisms can collect almost all of the available precipitation which can then be used for irrigation to drinking water depending on the level of purification the water is subjected to.   The volume of water one can expect to generate will depend on the following.

  • The average annual rainfall
  • The size of the roof
  • The type of roof – concrete, corrugated or tiled (thatch is not suitable)
  • Type of capturing mechanism
  • Space available for storage tanks

From the storage tanks the water is then either gravity fed or pumped on demand to where it is required.
