‘Water supply remains secure’
Cape Town has witnessed a drier-than-usual winter in 2026, while large parts of the south-western Western Cape experienced their driest July on record as the global effects of El Niño are being felt.
City officials are trying to avoid a repeat of the 2017/18 Cape Town water crisis, and the looming threat of a ‘Day Zero.’
As such, Dr Zahid Badroodien, Cape Town’s MMC for Water and Sanitation, allayed fears that Capetonians would be hit with water restrictions.
“Our city’s water supply remains secure in the immediate term,” Badroodien said on Monday. “We currently do not anticipate any water shortages.”
However, he did warn that the stored water must support a wider region through the hotter and drier summer months, until the next winter rainfall season.
The Western Cape Water Supply System also supplies other municipalities and the agricultural sector. The City says it is monitoring dam levels, rainfall and water demand.
City urges residents to use water responsibly
Badroodien said the City is continuing with pressure management, leak detection and repairs.
Other measures include pipe replacements and treated effluent use as an alternative water supply. The City is also investing in groundwater abstraction, water reuse and other diversified sources.
“Our water security is a regional responsibility,” Badroodien added. “We are engaging other municipalities as well as other users of the Western Cape water supply system to ensure a coordinated approach.”
“We continue to ask our residents and businesses to please help us reduce our water footprint and our water demand by using water responsibly.”
