Mumbai’s a booming urban city with defined high-rise buildings and compact living spaces that house millions of residents. While this dense housing model completely supports efficient urban growth, it also brings along hidden infrastructure challenges, and one of the most critical is access to safe and clean water. Among the many water-related problems faced by apartment dwellers, water storage tank contamination remains a major challenge, yet no one often talks about it. From underground sumps to overhead tanks, contaminated storage systems can significantly degrade the quality of water by the time it reaches individual homes.
If left untreated or unaddressed, this problem not only will impact daily living but also poses serious health issues for residents. In this article, we will explore the causes of water storage tank contamination in Mumbai apartments and the steps that residents can take to make sure that they are getting safe drinking water.

Understanding Water Storage Systems in Mumbai Apartments
Many apartments in Mumbai completely rely on a tiered water system, where water is supplied by the Brihanmumbai Municipal Corporation (BMC) through pipelines. From there, it is pumped to individual flats. Although there are municipal water systems that undergo quality checks, the storage tank buildings are often get neglected, which effectively leads to stagnation, contamination, and subsequent water quality issues by the time it reaches your tap.
Why Tanks Get Contaminated
1. Irregular or Inadequate Cleaning
Even though the BMC has recommended that apartment owners clean their tanks at least twice a year, many societies do not follow through. Over time, algae, sediment, and other organic matter build up on the tank walls and floor, contaminating the stored water.
2. Structural Issues and Ingress of Dirt
Many older tanks are unsecured, cracked, or poorly sealed, and this allows dust, debris, insects, rodents, and other sewage to find their way into water storage spaces.
3. Monsoon-Related Problems
Seasonal rains also play an important role. Frequent monsoon waterlogging and pressure changes can introduce muddy water or turbidity into pipelines and tanks.
4. Human and Animal Activity
Instances have been reported where tanks or their vicinity are completely unsecured, hence allowing unauthorised people or animals to access them, and this raises serious contamination and public health concerns as well.
Health Risks of Storage Tank Contamination
When water is stored in apartment tanks, it becomes contaminated, and it can lead to a range of health issues for residents. Moreover, consuming such water can result in gastrointestinal infections, which include diarrhea, cholera, or stomach flu as well. Additionally, bathing or washing with contaminated water can cause skin and eye infections, while chemical pollutants from sewage or industrial runoff can pose additional long-term health risks. Moreover, biofilm buildup inside tanks creates a protective environment for bacteria and parasites, allowing them to multiply unchecked. While these risks are significant for everyone, children, the elderly, and individuals with weakened immune systems are particularly vulnerable and more likely to suffer severe consequences from contaminated water.
