South Africa can be decribed as an arid country. Our rainfall varies considerably throughout the various regions. Rainwater is a free and untapped resource of water and when harvested corrcetly it can significantly reduce the water consupmtion of a business or household.
In areas with very high rainfall, rainwater harvesting is is an option to significantly reduce the use of municipal watr option. Instead of letting the water run down the roof and gutter it can be harvested and stored effectively and used as an alternative to the municipal supply. Our article on The beneficial impact that urban rainwater harvesting can have on a coastal towns in Kwa-Zulu Natal show just how big the oppertunity can be for rainharvesting in these areas
In dryer regions rainwater harvesting is a still a very good option and a protection against periods of drough. The design of systems in dryer regions differ significantky form areas with high rainfall. Here the focus is on maximising recovery during the short period of rain and increasing storage space so that water can be used contnaully in the dryer season.
Installing a rainwater system can also protect consumers against the variablity of supply. Recent events in South Africa where there were periods of sever water and power interruptions have highlighted the benefit of having localised water stored withing an house or commercial premises.
Water has always been cheap and plentiful in our country, but is is going to change. Therefore it is now the ideal time to investigate and consider doing rainwater harvesting.
