Last weeks rains in the greater Cape Town area have run into our dams and significantly filled dam levels however the Southern Cape is still experiencing lower than average dam levels. Now that the rainy season is steadily approaching many areas in the Western Cape,it is a truly a great time to build up a private fresh water supply. If our dams are able to capture and supply large regions of our country with fresh drinking water then harvesting the rain that falls on your roof instead of wasting it down the stormwater drain could significantly augment your families fresh water supply.
The following table shows the countries dam levels as of May 17 2010.
