The importance of water to South Africa In South Africa, the basic right to get enough water is written in its Constitution. It is written that ?everyone has the right to have access to sufficient water and food?. Only a few countries in the world enshrine this right in their Constitutions. Nevertheless, a lot of works need to be done to fulfill this right. Watson (2008) has highlighted that approximately 15 million people were not supported by safe water. Furthermore, more than 20 million people did not get adequate sanitation services in 1990. In addition, an extra population of nearly 10 million people who got access to a safe water source since then.

In addition, January is the month which has the largest rainfall during the whole year. Furthermore, the average of rainfall during these five months reaches about 90mm. However, during May to November only have a little rainfall, so Johannesburg will have a long period of arid time. The average of rainfall during this period is below 10mm per month and it is only one ninth compared with rainy seasons. 2.4 Water Pollution The water provision in Johannesburg is increasingly under pressure. Furthermore, eutrophication is a very serious issue.

Conclusion

Many people thought that the recycled water was made from sewage water still contain some dangerous substances. This would harm their health and cause illness. 6 Recommendations Comparing the two methods, big dams seems cost a lot of money and also they will cause a very serious environment impact. In contrast, wastewater recycling costs less than big dams and it is more environmental-friendly. So wastewater recycling is more suitable for Johannesburg. 7 Conclusion To sum up, in order to find a suitable method to provide water in Johannesburg, two methods have been introduced. Both of the two methods might be feasible to adopt in Johannesburg and both methods have its own advantages and disadvantages. However, environment impact may be the most important factor which needs to be seriously considered. So the most suitable method is wastewater recycling in Johannesburg. Because it is a more environmental-friendly method. (1403 words) Reference: David,W. (2011). Water supply and sanitation in South Africa.
