摘要

The similarities in climate and geology offer water resource managers in Cape Town and Perth an opportunity to learn from each other's experiences. While Cape Town relies mostly on surface water for supply, Perth uses 50% groundwater for its domestic and industrial use. It is proposed that certain aspects of Perth's water supply infrastructure could successfully be transposed for the exploitation of Cape Towns' groundwater resources. In Perth private boreholes is used to tap a shallow phreatic aquifer for garden irrigation. The Government of Western Australia encourages this practice. Cape Town has an opportunity to use water from the Cape Flats Aquifer in a similar manner. In this paper the use of the Cape Flats Aquifer for private garden irrigation is evaluated. By encouraging private landowners to develop private wells, large savings could be made in the amount of treated bulk water supply required by Cape Town. The Cape Flats Aquifer has been potential to meet a large part of the city's garden irrigation requirements. Though the impact of pollution on water quality remains uncertain and a concern, the general quality of water in the aquifer is adequate for irrigation requirements. If the use of private garden boreholes is to be successful, education of the public will be vital. It is envisaged that the City of Cape Town and the Department of Water Affairs and Forestry in partnership with private, education and research institutions take the lead in such education and the development of appropriate legislation and guidelines.
