Water Experts Stress Urgent Conservation as El Niño Raises Drought Risk

El Niño Heightens Water Scarcity Fears

Concerns are mounting over the impact of an anticipated long El Niño period, with weather patterns likely bringing higher temperatures and reduced rainfall. These conditions could worsen the country’s ongoing water supply issues, which are already affecting a number of communities.

Ferrial Adam from WaterCAN has called for residents to conserve water proactively, warning that heightened demand and persistent system constraints could push infrastructure beyond its limits, even if dam levels appear healthy now.

The Need for Stricter Water Restrictions

Adam emphasized that more than just personal responsibility is needed during these uncertain times. She has urged municipalities and the government to consider implementing robust water restrictions and ramp up public awareness campaigns. “We need more awareness around this, especially considering the hot summer we are expecting,” Adam noted.

She further explained, “It doesn’t matter if dams are full this year. If this is a prolonged El Niño, we could face a bigger disaster next year. Our systems are constrained. The infrastructure is damaged and fragile and as it gets hotter, reservoirs get emptier because half of them are leaking.”

Local Challenges in Tshwane Highlight Infrastructure Strain

Tshwane has emerged as a focal point of concern, with the city’s bulk water network described as under continuous strain. Despite some progress noted by Mayor Nasiphi Moya in rehabilitating water in Bronkhorstspruit, critical supply regions continue to face significant challenges.

• Garsfontein is maintaining improved water storage
• Elardus Park and Eersterust have healthy storage levels
• Mamelodi R1 reservoir remains empty
• Mamelodi R3 is critically low
• Parkmore and Derdepoort are experiencing low storage

Mayor Moya’s recent updates highlight both the successes and ongoing vulnerabilities within the system.

Water Supply Struggles Linked to Infrastructure and Demand

Lindela Mashigo, spokesperson for the City of Tshwane, has reported ongoing collaboration between the City and bulk supplier Magalies Water to alleviate water supply difficulties. The Wallmansthal reservoir, serving areas like Derdepark, Hoewes, and Baviaanspoort, has encountered declining storage levels over the past week.

These declines are attributed to both inconsistent supply from the Roodeplaat water treatment plant and high municipal demand, compounded by broader challenges upstream of the city’s system. Such vulnerabilities illustrate how water infrastructure can be especially susceptible during periods of elevated demand and climatic stress.

Preparation and Awareness Key to Mitigating Risks

As El Niño threatens to intensify heat and dry spells across the region, experts and officials are united in their call for early action, not only to weather the current crisis but to prepare for potentially more severe shortages in the coming year.

Residents are encouraged to:

• Reduce non-essential water usage
• Fix household leaks promptly
• Follow municipal updates on water restrictions and supply statuses
• Participate in community awareness campaigns

General uncertainty caused by weather patterns like El Niño makes water-wise behaviour increasingly important. South Africans have previously faced challenges such as drought, infrastructure limitations, and intermittent service interruptions. Preparing now, with a focus on conservation and maintenance, can significantly ease the burden on the water grid and help communities remain resilient during environmental extremes.

The Broader Importance of Water Conservation

Aside from the pressures brought on by El Niño, South Africa’s aging water infrastructure and growing urban populations underscore the fundamental necessity of wise water use year-round. By making smarter choices at home, work, and within municipalities, every citizen contributes to the collective effort in safeguarding this vital resource for the future.

With the threat of a lengthy drought looming, the message is clear: water conservation is not just a short-term emergency measure but an essential practice for long-term sustainability.
