USING WATER RESPONSIBLY,
THE WATER WISE WAY
Water Wise is the environmental brand of Rand Water, aiming to educate
South Africans on how to use water efficiently (water conservation), reduce
wasteful water use, prevent water pollution, pay for water, protect water
sources and implement business practises and principles that are water wise.
outh Africa is a naturally a semi-arid country that
receives less than half the annual average rainfall
Sreceived by the rest of the world. Rainfall is not
distributed evenly throughout the year or across the country.
South Africa is also classified as water scarce, based on
climatic conditions and water demands. Simply put, water
scarcity means there is not enough water to meet all the
demands of a region. There are a number of factors that
contribute to South Africa’s water crisis, including:
1. Non-revenue water (NRW): this is the water that
doesn’t reach the end user and is lost through leaks and
unbilled unmetered water. South Africa’s NRW loss is 41%,
whereas the global best practise is 15%.
2. South Africa’s water use: on average is approximately
235 litres of water per person per day versus the global
average use of 173 litres per person per day.
3. Ageing infrastructure: the country’s water network is
over 30 years old, and in many circumstances much older,
and while it is not suitable for the increased demand, it is
also not being maintained.
4. Overpopulation: by 2019, the country had already
exceeded the population numbers expected for 2030. The
current figure for South Africa is over 60 million.
5. Urbanisation: 63% of South Africans live in urban areas
and this is expected to reach 71% by 2030.
