According to News24, the Gauteng Department of Health has dismissed claims the province’s tap water is unsafe to drink. Department spokesperson Motalatale Modiba said messages circulating on social media discouraging residents from drinking tap water were false and malicious.
However, in South Africa, according to the Green Drop Report 2022, 52 % of our sewage treatment works fall into risk categories. Sewage works are discharging inadequately treated sewage effluent into water courses that may eventually become the source water for our bulk drinking water treatment systems.
We have compiled some background information on Cholera: how it’s transmitted, what you can do to safeguard against infection and products that will help keep you safe from bacteria, viruses and other water contaminants in your home and businesses.
How Cholera Is Transmitted
Cholera is typically transmitted through contaminated water or food. The bacteria responsible for cholera, Vibrio cholera, can survive in water or food for up to several days, allowing it to be transmitted through the ingestion of contaminated material.
In areas with poor sanitation, cholera can spread quickly through the contamination of water sources with human waste. In addition to contaminated water, raw or undercooked food that comes from contaminated water sources, and unwashed fruit and vegetables, can also transmit cholera.
The disease is not typically transmitted through direct contact with an infected person, and it is not airborne. However, close contact with faecal matter from an infected person can pose a risk for transmission. Proper sanitation and hygiene practices, such as hand washing and proper food handling, can help prevent the spread of cholera.
How Does One Remove Cholera from Water?
- Boiling: Boiling water is the most effective way to kill cholera bacteria. You should bring the water to a rolling boil for at least one minute (7 minutes is advised) to ensure that all the bacteria are killed.
- Chlorination: Adding chlorine to water can also effectively kill cholera bacteria. You can use household bleach that contains 5-6% sodium hypochlorite to treat water. The recommended concentration for disinfecting water is 0.5 to 1.0 parts per million (ppm) of chlorine. You should let the treated water sit for at least 30 minutes before consuming it.
- Filtration: Certain types of filters can remove cholera bacteria from water. For example, ceramic, UV, activated carbon, ultrafiltration or Reverse Osmosis filters can be effective in removing bacteria and other contaminants.
It’s important to note that these methods only work to remove cholera bacteria from water. If the water is contaminated with other types of contaminants, such as chemicals or heavy metals, additional treatment may be necessary. Additionally, it’s important to ensure that the water source is properly protected from contamination to prevent the spread of cholera in the first place.

No Matter Your Water Purification Need, We Have The Solution!
With our decades of expertise and our wide range of modular, innovative products and technologies, there isn’t a water problem we cannot solve for you!
- Ceramic filters: These filters use a porous ceramic material to filter out contaminants, including bacteria like cholera. Ceramic filters can remove up to 99.99% of bacteria from water.
- Reverse osmosis filters: Reverse osmosis filters use a semipermeable membrane to remove contaminants from water. These filters can remove bacteria, viruses, and other contaminants, including cholera.
- Ultrafiltration filters: These filters use a membrane to filter out bacteria and other contaminants from water. Ultrafiltration filters can remove bacteria like cholera, as well as other pathogens and particles.
- Ultraviolet (UV) light filters: They can be effective in removing cholera from water.
- UV light works by damaging the DNA of bacteria, viruses, and other pathogens, including cholera, which then prevents them from reproducing and causing illness. UV water purifiers are designed to kill a wide range of microorganisms, including cholera, by exposing the water to UV light. The process is quick, efficient, and does not require any chemicals or additional treatment.
- However, it’s important to note that UV water purifiers only work to disinfect water and remove microorganisms. They do not remove other types of contaminants, such as chemicals or heavy metals, from the water.
- Also please note that the effectiveness of UV light in removing cholera bacteria from water can be reduced if the water contains high levels of sediment or other particles. The cholera bacteria can hide behind or within the particles, which can shield them from the UV light and prevent them from being effectively disinfected. It’s also important to note that the intensity of the UV light and the exposure time can also affect the effectiveness of the treatment.
It is, therefore, extremely important that you consult with us for the correct combination of water filters that can remove sediments, chemicals and metals and treat harmful organics like bacteria. The correct water filter ensures correct hygiene, health and taste for you and your family and business. See our recommended cholera-busting products here.
Two More Important Points
- Cholera is particularly unsafe for elderly and vulnerable people, it is very important to thoroughly wash all fresh fruit and vegetables with clean, safe water.
- Keep your kitchen properly sanitised:
- Wash your hands frequently: Regularly washing your hands with soap and water can help to prevent the spread of cholera. Be sure to wash your hands thoroughly before handling food, after using the restroom, and after handling any potentially contaminated materials.
- Keep surfaces clean: Use a disinfectant cleaner to wipe down kitchen surfaces, including countertops, cutting boards, and utensils. You should also regularly clean your kitchen sink and any other surfaces that come into contact with food or water.
- Cook food thoroughly: Cook all food, particularly seafood, meat, and poultry, to the appropriate temperature to ensure that any potential bacteria, including cholera, are killed.
- Practice good food hygiene: Proper food hygiene practices, such as keeping raw and cooked food separate, storing food at the appropriate temperature, and avoiding cross-contamination, can help to prevent the spread of cholera.
Use safe drinking water: Ensure that your drinking water is safe by using treated or boiled water.
H2O | BWT Products related to removing harmful contaminants like Cholera in your home and business.
Your GAC/KDF cartridge is not guaranteed to remove Cholera or other bacteria.
However, KDF is bacteriostatic – it prevents growth of bacteria inside the cartridge.
We recommend combining your GAC/KDF filter with an Ultraviolet or Ultrafiltration water Filter.
You can also add the inline BWT B-SAFE Bacteria-Safety Filter onto existing GAC/KDF systems.

Commercial Reverse Osmosis
The Woda-Pure removes bacteria like Cholera. It also removes chlorine and other harmful substances present in water, utilising ultrafiltration and activated carbon. All valuable minerals are retained in the water for the best taste and a full aroma in hot and cold drinks.
MCS400 or the MPC400
Both of these products provide ultrafiltration to remove bacteria like cholera. An added advantage is that they add magnesium to your water for better health and a bit of taste. You need to choose the MPC 400 if you are in a hard water area.
BWT B-Safe Bacteria -Safety Filter
- This small and simple filter provides highly efficient protection against legionella and bacteria like Cholera. The installation is uncomplicated and directly at the point of use.
