WHAT'S HAPPENING?

 
  1. The situation with the Hartbeespoort Dam:

    The Hartbeespoort Dam was built in 1923 for irrigation purposes. It soon became a water source for primary consumption and also an attractive recreational destination for many watersports enthusiasts, anglers and local and international tourists.

    Due to rapid urban development and industrial growth in the Hartbeespoort Dam catchment area, the volumes of water and the loads of plant nutrients (phosphates and nitrogen) reaching the dam have increased. This trend may continue in the future as the urban areas in the catchment are expected to grow steadily.

    This nutrients are commonly found in fertilisers, industrial wastewater, sewage effluent and products such as soap and washing powders. Although present in very low concentrations in the dam water and sediment, these plant nutrients cause excessive growth of algae and waterweeds such as hyacinth. This condition is described as eutrophication.



  2. Cholera Risks - From well serviced areas

    The current cholera epidemic has again reminded us of the importance of effective sanitation services and the need to prevent faecal contamination of our water resources. Because the cholera bacterium is waterborne, rivers contaminated with human faeces transmit the disease from one community to another, contributing to the rapid spread of the disease.

    The communities most at risk from the disease are, therefore, those with poor or no sanitation services and those who rely on untreated water directly from rivers for their drinking water and for washing purposes. The Department of Water Affairs and Forestry has consequently focussed on providing water and sanitation services to these communities.

    However, the risks associated with cholera are not limited to poorly serviced areas, and any settlement where there is faecel contamination of water resources is a risk.
