South Africa (SA) is facing a growing water challenge, with more than a third of treated water lost each day and household use far above global averages. Experts warn that, if current trends continue, demand could outstrip supply by 2030.
The Water Research Commission (WRC) has launched the “A Water Wise Nation” campaign to encourage citizens to use water more responsibly. The initiative focuses on changing behaviour, raising awareness of water scarcity, and promoting sustainable practices.
Dr Jennifer Balatedi Molwantwa, Chief Executive Officer of the WRC, said the greatest priority is tackling non-revenue water losses, caused by leaks in municipal infrastructure. “Local governments must ensure that water reaching communities is not wasted. Every litre lost is both a financial and environmental setback,” she said.
South Africans currently use an average of 320 litres per person per day, which is well above the global norm of 150–170 litres. Molwantwa stressed that households, businesses, and farmers all have a role to play in conserving water. Simple steps, such as fixing leaks, using water-efficient shower heads, reducing bath use, and reusing water in toilets, can make a significant difference.
The campaign also targets schools, aiming to teach children the value of water from an early age. At the same time, the WRC is promoting technologies such as pressurised irrigation, decentralized water reuse, and dual-flush systems. While SA has the tools to modernise its water systems, Molwantwa noted that slow adoption by municipalities and outdated procurement policies are holding back progress.
She clarified that a “Day Zero” scenario, where taps run dry, is not expected. However, if infrastructure issues are not addressed and losses rise above 40%, available water may not be enough to meet everyone’s needs, particularly during droughts or energy-related interruptions in treatment.
“The aim is that by 2029–2030, SA will be a water-wise nation,” Molwantwa said. “Both government and citizens must make smart choices, conserve where possible, and ensure sustainable water supply for the future.”
The WRC warns that without urgent action, the country risks a serious water shortfall within the next decade.
