Frequently Asked Questions
Everything you need to know about overhead water tank cleaning.
Why is overhead tank cleaning important for health?
Overhead tank cleaning is essential because water stored for long periods collects dirt, sediment, algae, bacteria, and harmful pathogens. Without regular cleaning, this contaminated water is used for drinking, cooking, and bathing — causing serious health problems such as stomach infections, skin issues, and water-borne diseases. Professional cleaning removes all harmful elements and ensures your water remains safe and hygienic.
How often should overhead tank cleaning be done?
Ideally, overhead tank cleaning should be done once every six months for residential properties. For apartments, commercial buildings, hospitals, and hotels, cleaning should be done every three to four months depending on water usage and contamination levels. Regular cleaning prevents sludge buildup, bacterial growth, and foul odors.
Is overhead tank cleaning really necessary?
Yes, absolutely. Without regular cleaning, bacteria multiply rapidly inside the tank and contaminate all stored water. Over time, this leads to serious illness for your family. Even if your water looks clear, invisible bacteria and pathogens can still be present. Professional cleaning is the only way to ensure 100% safe water.
How long does the cleaning process take?
The entire overhead tank cleaning process typically takes between 45 to 90 minutes, depending on the size of the tank, level of contamination, and ease of access. Larger commercial or industrial tanks may require slightly more time, but the process is always planned to minimize inconvenience while ensuring complete hygiene.
Can I use the water immediately after cleaning?
Yes. After professional overhead tank cleaning, the water is completely safe for use. The process includes thorough washing and disinfection using food-grade, eco-friendly chemicals that eliminate bacteria without leaving harmful residues. Once the tank is rinsed and refilled, the water can be safely used for drinking, cooking, bathing, and all household activities.
Is the process safe for plastic and Sintex tanks?
Yes. We use only tank-safe chemicals and appropriate pressure settings for every tank material — including plastic, Sintex, concrete, stainless steel, and fiber tanks. Our technicians are trained to adjust the cleaning method based on the tank type to ensure no damage occurs during the process.
What happens if tank cleaning is ignored for a long time?
If cleaning is ignored, thick layers of sludge, rust, algae, and bacteria develop inside the tank. This contamination spreads into pipelines and household taps, making water unsafe for consumption. This can result in frequent illnesses, unpleasant taste and smell, damage to plumbing systems, and reduced lifespan of the tank itself.
