This month at Water Wise

 "Welcome to Summer"

It seems we have skipped spring and jumped straight into summer! The country has seen temperatures sky-rocket, with places like Upington hitting highs of 37°C. Johannesburg has been seeing highs of between 25°C and 27°C. We have had some rain in Gauteng, but unfortunately it is not enough, and forecasts predict heavy rains towards the end of the summer season only. This means we need to be extra careful of conserving our water, especially during the hot, dry period to come. Always be Water Wise!

Water Wise Tip of the Month:
As temperatures soar, and rainfall remains evasive, we need to look at ways of saving as much water in the home and garden as possible. This month, think about re-using greywater for watering your garden, washing down paving, and cleaning your car. Greywater can be used straight from the source, as long as there is no chance it contains any bacteria, and is not stored for longer than 24 hours. Only use greywater from bathrooms basins, showers, and baths.

Weather for September/October

Weather logo
Given the current strain on water resources in the south-western parts of the country and seemingly no significant rainfall activities during spring, it is recommended that the current drought measures continue for the foreseeable future. Forecasts however do indicate that there is an increased chance for above-normal rainfall between spring and late spring (Oct-Nov-Dec) over the north-eastern parts of the country. Conditions over the Indian Ocean promote this forecast; however, there are indications that these conditions may start to moderate during late spring. Weather

Water Wise Events

This month, Water Wise celebrates WeedBuster Week! This environmental celebration was initiated by the Department of Environmental Affairs, and is linked to various invasive plant control initiatives around the world. The aim of this campaign is to increase public awareness on the issue of invasive alien plants to promote community ownership of the problem and to encourage management and containment of invasive plants across the country.  WeedBuster Week is usually celebrated in the second week of October every year. Invasive alien plants, which are non-native plants that spread and displace indigenous plants, cause billions of Rands of damage to South Africa's economy every year, and pose a threat to water security, biodiversity, the productive use of land, and the ecological functioning of natural ecosystems. Please visit the Invasive Species South Africa website for more.
