'Unfiltered Water' Warnings Are Fake, Hollers BMC
By A Draft Colaba Correspondent
In a city as dynamic and densely populated as Mumbai, where civic infrastructure is perpetually under scrutiny, any disruption in essential services sparks immediate concern. Recently, a wave of misinformation regarding the city's water supply caused alarm among residents, prompting the Brihanmumbai Municipal Corporation (BMC) to intervene and set the record straight. The municipal body has urged citizens to dismiss baseless claims suggesting that untreated water is being supplied to households due to a filtration system failure.
Recognising the potential for widespread panic, the BMC promptly issued a clarification, unequivocally stating that there has been no malfunction in the city's water filtration system. In an official statement, the civic body reassured residents that Mumbai's water treatment plants are functioning optimally and that there is no deviation from the standard filtration and purification processes.
The BMC emphasised that all water supplied to the city undergoes stringent quality checks, ensuring it meets safety standards before reaching households. They further clarified that any advisories regarding water quality or precautionary measures would be communicated through official channels, not through unverified social media forwards.
This response highlights the municipality’s commitment to maintaining public trust while reinforcing the importance of relying on credible sources for critical information.
Mumbai receives its water from several lakes and reservoirs, including Tulsi, Vihar, Upper Vaitarna, Bhatsa, Tansa, and Modak Sagar, located in and around the city. The water from these sources undergoes an extensive multi-stage purification process before being supplied to residents.
At the water treatment plants, raw water is first treated with coagulants like alum (aluminium sulfate), which helps in binding dirt, silt, and other suspended particles together. This process forms larger particles called "flocs," making it easier to remove impurities in the next stage.
The water is then moved to sedimentation tanks, where the heavier flocs settle at the bottom, leaving clearer water on top. This is a natural process that significantly reduces the amount of solid particles in the water.
The clearer water then passes through multiple layers of sand, gravel, and charcoal filters. These filters remove finer impurities, bacteria, and other microorganisms. Mumbai’s filtration system is designed to comply with World Health Organisation (WHO) standards for safe drinking water.
To ensure the water is free from disease-causing microbes, it is disinfected using chlorine or ozone. Chlorination is the most commonly used method, effectively eliminating bacteria, viruses, and parasites while maintaining a residual disinfectant level to prevent recontamination.
The pH level of the water is monitored and adjusted to ensure it remains within safe limits for consumption. In some cases, fluoridation is carried out to help prevent dental health issues.:
Once treated, the water is stored in massive reservoirs before being pumped through a network of pipelines to reach households across Mumbai. The BMC regularly tests water samples from various locations to ensure that water quality is maintained until it reaches consumers.
The BMC follows strict guidelines to ensure that the city's water supply meets WHO standards for drinking water. These guidelines cover:
Microbiological safety: The absence of harmful bacteria like E. coli and cholera-causing pathogens.
Chemical safety: Ensuring that water does not contain toxic substances like lead, mercury, or excessive fluoride.
Acceptable turbidity levels: Water must be clear, without excessive suspended particles.
Residual chlorine levels: A small amount of chlorine is maintained in the water to prevent bacterial regrowth in pipelines.
Regular testing is conducted in over 100 locations across Mumbai to verify compliance with these standards.
While the BMC’s clarification has put to rest the current rumours, it also underscores a recurring issue—how quickly misinformation spreads and the potential consequences of acting upon unverified claims.
In the wake of such incidents, the BMC’s proactive approach serves as a reminder of the need for responsible communication. Residents are urged to verify information before forwarding messages, especially when such claims pertain to essential services. Relying on official sources—such as government websites, verified social media handles, and reputable news outlets—can prevent unnecessary panic and ensure that accurate information reaches the public.
As Mumbai continues to grow and its infrastructure becomes more complex, it is imperative that residents remain discerning about the information they consume and share. Awareness campaigns, community engagement, and digital literacy initiatives can go a long way in curbing the spread of falsehoods.
For now, Mumbaikars can breathe easy, knowing that their drinking water is safe. However, as the city moves forward, both authorities and residents must work together to ensure that facts, not fiction, dictate public discourse.

With the advent of digital communication and instant messaging platforms, misinformation travels faster than ever before. Over the past few days, messages have been widely circulated on social media and WhatsApp groups, warning Mumbaikars that the BMC’s water filtration system is out of order. These messages claimed that untreated water was being supplied and advised people to boil and cool water before consumption as a precautionary measure. The messages also suggested that the system would take several days to be fixed, fuelling anxiety and prompting many to take unnecessary measures.

Mumbai, a city that relies heavily on its civic machinery to function seamlessly, has witnessed similar instances in the past, where false alarms about public services have led to widespread panic. Be it rumours of impending water shortages, power outages, or fuel crises, misinformation tends to gain traction quickly, causing unnecessary disruptions to daily life.

While the BMC’s clarification has put to rest the current rumours, it also underscores a recurring issue—how quickly misinformation spreads and the potential consequences of acting upon unverified claims.
Mumbai’s history is replete with instances where false messages have caused undue panic. From viral messages predicting fuel shortages leading to long queues at petrol pumps to exaggerated claims about natural disasters triggering mass hysteria, the city has seen its share of baseless alarms. In many cases, these rumours have not only inconvenienced residents but also placed undue pressure on the civic administration.Even in the realm of public health, misinformation has played a damaging role. During the peak of the COVID-19 pandemic, false claims about vaccine efficacy and government directives led to confusion, requiring repeated clarifications from authorities.
In the wake of such incidents, the BMC’s proactive approach serves as a reminder of the need for responsible communication. Residents are urged to verify information before forwarding messages, especially when such claims pertain to essential services. Relying on official sources—such as government websites, verified social media handles, and reputable news outlets—can prevent unnecessary panic and ensure that accurate information reaches the public.
Moreover, the role of media and civic authorities in combating misinformation cannot be overstated. Timely intervention and transparent communication are key in maintaining public confidence and preventing disruption. The BMC’s swift response to this water supply rumour is an example of effective governance, demonstrating that fact-based communication can counteract the dangers of misinformation.While the BMC has reassured residents that Mumbai’s water supply remains safe, the incident serves as a wake-up call for a larger issue—how easily misinformation can shape public perception and behaviour.
As Mumbai continues to grow and its infrastructure becomes more complex, it is imperative that residents remain discerning about the information they consume and share. Awareness campaigns, community engagement, and digital literacy initiatives can go a long way in curbing the spread of falsehoods.
For now, Mumbaikars can breathe easy, knowing that their drinking water is safe. However, as the city moves forward, both authorities and residents must work together to ensure that facts, not fiction, dictate public discourse.
