Is now a good time for your household to stockpile emergency water supplies?

The South African National Bottled Water Association is urging residents to maintain emergency drinking water supplies as municipal networks face ongoing strain. This guidance comes as experts warn that a strong El Niño event will bring below-normal rainfall and increased heat through early 2027.

Why it matters

Widespread water outages and recent reports of tap water contamination have highlighted the vulnerability of national supply chains. Storing emergency water serves as a vital safeguard for families dealing with infrastructure instability and climate-driven drought.

The National Bottled Water Association recommends storing 4 litres per person daily, totalling 48 litres for a family of four over three days. A 2025 WaterCAN survey identified E. coli in household water supplies across 8 municipalities.

The players

South African National Bottled Water Association

This is a trade body that represents the bottled water industry and provides guidance on hydration standards and storage practices.

South African Weather Service

The national institution is responsible for monitoring climate patterns, weather forecasting, and issuing severe weather warnings.

WaterCAN

This is a civil society initiative that focuses on water quality monitoring and public advocacy for the protection of water resources.

The details

Households are encouraged to rotate their stored bottled water, ensuring the oldest inventory is used first to maintain quality. Supplies should be kept in cool, dark, and chemical-free environments to prevent degradation of the water quality.

2015/16 saw the occurrence of a previous strong El Niño event.
A citizen-science survey was conducted by WaterCAN in 2025.
Tap water contamination was reported in eastern Tshwane in October 2026.
The strong El Niño weather pattern is expected to continue until early 2027.

Seasonal Patterns

The current weather forecast follows a pattern set by the 2015/16 El Niño event which significantly impacted national rainfall. This period marks a continued departure from historical norms as the country experiences extended periods of below-normal precipitation.

Residents in affected areas like Johannesburg and Nelson Mandela Bay should prioritise storing at least 12 litres of water per person to cover a three-day window. Ensure that stored containers are kept in dark, cool areas to protect against contamination.

The takeaway

Maintaining a basic emergency water supply is a prudent step for any household to mitigate the risks posed by unpredictable municipal outages. By following storage rotation practices, families can ensure they have access to safe drinking water when central systems fail.
