With the rainy season hopefully just around the corner, you might consider harvesting your own rain water.
South Africa is a water-scarce country, and the water resources are under tremendous pressure from a growing population, on-going pollution, wetland destruction and climate change. The water that we do have, in particular, in the Magaliesburg districts, is either polluted with acid mine water or sewage, and then there is the constant threat of mining in the area, which will place added stress on our water resources. It is predicted that Gauteng will be facing a water shortage as early as this year still, as demand is increasing faster than the costly water transfer schemes can be built. The second phase of the Lesotho Highlands Water Transfer Scheme will only bring relief to Gauteng by 2019.
As has been experienced in many municipal areas, neither the supply nor quality of water can be guaranteed. A viable option to save clean water could be rain water harvesting from your roof. Rain water tanks provide a renewable supply of natural, soft, clear and odourless water without harming the environment. The rain water collection capacity from your roof is: 1mm of rain = l litre of water per m² of roof area (allow a wastage of 15%).
Tanks should be located on the corners of your house. They should be covered to prevent evaporation and mosquitoes from breeding. Install a filter to catch leaves and twigs flowing from the roof. The tap should be raised, so you can fit a bucket under it to prevent sediment from the bottom of the tank from clogging.
