A Closer Look at Waterborne Diseases: Why Water Tank Cleaning is a Must


Water is the essence of life. It not only sustains our physical health but also forms a vital part of our daily routines, from cooking and cleaning to drinking. Yet, how often do we stop to consider the quality of the water we consume and utilize every day? The alarming rise in waterborne diseases globally has made it more crucial than ever to take this question seriously.

Waterborne diseases, caused by microorganisms that are transmitted through contaminated water, affect millions of people worldwide. The World Health Organization estimates that over 2 billion people are at risk of these diseases, leading to approximately 3.4 million deaths each year. A significant factor contributing to this grim reality is the contamination of water stored in tanks, both in residential and commercial setups.

Unclean water tanks can become a breeding ground for pathogens, leading to the spread of diseases like cholera, typhoid, and dysentery. Regular cleaning of these tanks is not just a matter of cleanliness but a vital step towards safeguarding health. In this blog, we will take a closer look at waterborne diseases and explore why water tank cleaning is a must to prevent them. Join us as we delve into the hidden dangers lurking in unclean water and learn how to protect ourselves and our communities.

Understanding Waterborne Diseases

Definition and Types

Waterborne diseases are illnesses caused by pathogenic microorganisms that are transmitted through contaminated water. These diseases can be viral, bacterial, or parasitic in nature, and they are a major public health concern across the globe.

Here are some common examples of waterborne diseases:

1. Cholera: Caused by the bacterium Vibrio cholerae, cholera leads to severe diarrhea and dehydration. It often spreads through untreated sewage in the water.

2. Typhoid Fever: Typhoid is caused by the bacteria Salmonella typhi, transmitted through contaminated food or water. It results in high fever, weakness, and abdominal pain.

3. Dysentery: Both bacterial and amoebic dysentery are spread through water contaminated with fecal matter. They cause abdominal cramping, fever, and bloody stools.

These examples represent only a fraction of the waterborne diseases that threaten human health. Their transmission is often directly linked to the quality of water in storage tanks and supply systems.

Symptoms and Treatment

Recognizing the symptoms of waterborne diseases can facilitate early intervention and treatment. Common symptoms include diarrhea, nausea, vomiting, abdominal cramps, and fever. Some diseases may also cause more severe problems, such as kidney or liver failure if left untreated.

Treatment often involves rehydration and, in some cases, antibiotics or other medications. Preventing these diseases, however, is the most effective way to protect against them. Regular water tank cleaning plays a pivotal role in this prevention, ensuring that water remains uncontaminated and safe to use.

The Role of Water Tanks in Spreading Diseases

How Contamination Occurs

Water tanks are essential for storing water in both residential and commercial settings. While they provide a convenient source of water, they can also become hubs for contamination if not maintained properly. Here’s how contamination often occurs:

Algal Growth: Sunlight and nutrients can lead to algal blooms within tanks. These algae can harbor bacteria and other pathogens.

Bacterial Growth: Stagnant water and residues can encourage the growth of harmful bacteria like E. coli, leading to potential health risks.

External Contaminants: Open or improperly sealed tanks can allow insects, debris, and other pollutants to enter, contaminating the water.

Corrosion and Material Breakdown: Aging tanks or those made from inferior materials may corrode or break down, releasing harmful substances into the water.

These factors create an environment conducive to the growth of pathogens, which can lead to waterborne diseases.

Importance of Water Tank Cleaning

Cleaning Techniques and Procedures

Cleaning water tanks is a specialized task that requires attention to detail and proper techniques. Below are some common methods and tools used for water tank cleaning:

1. Draining and Scrubbing: Empty the tank and scrub the interior surfaces with brushes or pressure washers, using approved disinfectants.

2. Vacuuming: Utilize specialized vacuum cleaners to remove sludge and sediment at the bottom of the tank.

3. Disinfection: Use safe and approved chemicals like chlorine to disinfect the tank. It’s essential to follow guidelines for the right concentration to avoid over- or under-disinfection.

4. Professional Cleaning: Consider hiring professionals for larger or more complex tanks. They will have specialized equipment and knowledge to ensure thorough cleaning.

5. Inspection: A visual inspection or even using underwater cameras can help ensure that all areas are clean and in good condition.

Regular Maintenance and Inspection

Regular cleaning is only part of the solution. Here’s why ongoing maintenance and inspection are also crucial:

Scheduled Cleaning: Establish a regular cleaning schedule, depending on the usage and local regulations. For many tanks, biannual cleaning may be advisable.

Regular Inspections: Frequent inspections can catch early signs of contamination, cracks, or other problems, ensuring timely intervention.

Use of Quality Materials: Ensure that the tank’s material is of good quality and resistant to corrosion and algae growth.

Sealing and Security: Ensure that the tank is properly sealed to prevent the entry of external contaminants.

Regulatory Compliance and Social Responsibility

Clean water is not just a personal concern; it is a matter of public health and community welfare. Both individuals and organizations must consider legal obligations and social responsibilities when it comes to water tank cleaning and maintenance.

Regulatory Compliance

1. Local Regulations: Many jurisdictions have specific laws and guidelines for water tank cleaning. These may include frequency, methods, and record-keeping requirements.

2. Health and Safety Standards: Following accepted health and safety protocols ensures that the water remains potable and does not pose health risks.

3. Environmental Considerations: Proper disposal of waste and chemicals used in cleaning must comply with environmental regulations to avoid secondary contamination of soil or other water sources.

Social Responsibility

1. Community Health: Clean water tanks benefit not only individual households but the broader community. Waterborne diseases can spread quickly, so community-wide diligence is essential.

2. Educational Outreach: Sharing knowledge about waterborne diseases and the importance of water tank cleaning can foster a culture of responsibility and care.

3. Corporate Responsibility: Businesses and large complexes must prioritize water tank cleaning as part of their corporate social responsibility initiatives, ensuring the health and safety of both employees and customers.


The journey of water from source to tap is one filled with potential pitfalls and dangers, and the final storage in water tanks is a critical stage that demands our attention. The unseen world of microorganisms lurking in improperly maintained water tanks can lead to diseases that have devastating impacts on individuals and communities.

Waterborne diseases are not relics of the past; they are current and pressing threats that claim millions of lives annually. They remind us that clean water is not a luxury but a vital necessity. Regular water tank cleaning is not a choice but an essential preventative measure.

By understanding the nature of waterborne diseases, recognizing the role of water tanks in their spread, and implementing diligent cleaning and maintenance practices, we can make significant strides in protecting public health.

In our homes, our schools, our workplaces, and our communities, the responsibility for clean water lies with each of us. Let us embrace this responsibility with the seriousness it deserves and ensure that the water we consume is not just clear but clean, safe, and life-sustaining.

Water is life’s most essential resource. Let’s treat it with the respect and care it warrants, for ourselves and for future generations.
