Residents and businesses urged to ensure water is safe for consumption
Those who receive water from trucks need to ensure that the trucks are clean and well-maintained.
With essential water infrastructure upgrades underway in large parts of Gauteng, residents and businesses have seen their taps run dry, causing them to rush out to source, and store, water to meet their daily needs.
In doing so, all water users such as consumers, retailers, restaurants, manufacturers and households must ensure their drinking water is safe.
“While these upgrades are necessary for long-term water security, the temporary disruptions may lead to residents sourcing and storing water independently out of anxiety or desperation.

“’However, without proper measures to ensure safety, these actions may bring unexpected potential risk to families.
“With the right intervention, the integrity of the water you’re sourcing and storing will make it suitable for consumption,” said Marina Sander, compliance expert and food safety testing provider for AssureCloud.”
Her job is to provide SANS 241 water testing, a legislative requirement for water suppliers that indicate their water is suitable for drinking.
Her guidance on the correct procedure for sourcing, assessing the quality of, and storing water over the next few weeks while upgrades are underway includes assessing the water you have sourced.
“Wherever you are sourcing water from, inspect the vessel it is contained in for damages or tampering to the lid or packaging, then assess the appearance of the water, as well as how it smells,” she said.

Water with a strong or unusual odour may indicate contamination.
Common smells include chlorine, anything similar to rotten eggs, or a musty odour.
The water should be clear. Brown, yellow, or cloudy water can signal the presence of rust, sediment, or microorganisms.
Any change in the taste of water, such as a metallic or sour flavour, could be a warning sign of contaminants.
She urges people to take control of their water, and if they suspect contamination, several methods can be used to ensure safe drinking.
“Boil water for at least one minute (three minutes at higher altitudes) to kill harmful bacteria, viruses, and parasites.
“Chlorine tablets can also be used and they are available at pharmacies and outdoor supply stores.
“Use chlorine tablets to disinfect water. Sander urges people to follow the manufacturer’s instructions for proper dosage and adhere to the timeframe.”

She added that ultraviolet light can be used to kill microorganisms.
“They are available as portable devices or installed units. Ensure the water is clear before using UV light, as particles can shield microorganisms from the UV rays,” she said.
Bleach can be used in case of an emergency.
Sander recommends the use of regular unscented household bleach (5-6% chlorine) for emergency disinfection.
Eight drops should be added (about 0.5 ml) of bleach per gallon (3.8 litres) of water, stir well, and let it stand for at least 30 minutes before use.
Those who receive water from trucks need to ensure that the trucks are clean and well-maintained.
“Residents can request water quality certificates from the supplier (if a private supplier), focusing on both microbiological and chemical parameters.”

Another recommended method is to transfer water promptly to clean, designated storage containers and ensure your hands are clean so that you don’t unintentionally pass contaminants into the vessel.
For water storage, containers with tight lids to prevent contamination can be used.
Water can be stored in a cool, shaded area (ideally below 15-20°C for cold water and above 60°C for hot water).
Regular inspection of water tanks and storage containers is recommended for cleanliness and signs of deterioration.
There should be monitoring for any signs of bacterial growth pathogens like E. coli and coliforms, which can cause gastrointestinal illnesses.
“By following these recommendations and staying informed through official updates, residents and businesses can manage their water needs and get through this period with confidence.
“We urge people to prioritise water safety to ensure a healthy and secure water supply for your household or business,” said Sander.
