Water storage tanks are essential for industrial operations, especially for those in rural areas where access to clean water may be limited. These tanks require regular maintenance to ensure they function effectively and provide clean water for daily use. 

However, it can be challenging to determine when your water storage tank needs attention, and identifying these signs can result in contaminated water. This article will discuss some signs that you need water tank cleaning services. 

1. Poor Water Quality

The water quality stored in your tank is a crucial indicator of whether your tank needs attention. If you notice any changes in the water quality, such as a foul smell or unusual taste, it could indicate that your tank needs cleaning. 

Contaminants can build up over time, leading to a change in the water’s taste and smell. Sometimes, the water may appear cloudy or have a brownish tint. This is a clear indication that your tank needs immediate attention.

2. Reduced Water Pressure

Reduced water pressure is another sign that your water storage tank needs attention. If you notice a decrease in water pressure when using taps or showers in your home, it could be a sign that your tank is malfunctioning. 

Moreover, reduced water pressure could be due to a clogged filter or a blocked valve, which can restrict water flow. In some cases, the water pressure may gradually decrease over time, making it more challenging to identify the issue. You can call for regular maintenance of your tank can help prevent such problems.

3. Leaks

Leaks are a common problem with water storage tanks and can be caused by various factors. A leak can occur due to a damaged tank or faulty valves and fittings. Leaks can be identified by puddles of water around the tank or damp walls and floors. 

If you notice any leaks, you must address them immediately to prevent further damage. Ignoring leaks can lead to significant water loss, which can be costly and detrimental to your water supply.

4. Build-up of Sediment

The sediment build-up is another sign that your water storage tank needs attention. Sediment can accumulate at the bottom of your tank over time, reducing water quality and clogged filters. The build-up of sediment can also cause damage to the tank’s interior, leading to leaks and other issues. Regular tank cleaning can help prevent sediment build-up and prolong its lifespan.

5. Age of the Tank

Most tanks have a 10-15 years lifespan, after which they may start to deteriorate. Older tanks are more susceptible to cracks, leaks, and other issues, affecting water quality and supply. If your tank is approaching its lifespan, it may be time to consider replacing it with a new one.

6. Insects and Animals

Insects and animals can also indicate that your water storage tank needs attention. Insects such as mosquitoes can breed in stagnant water, while animals such as rats can gnaw through the tank’s exterior, leading to leaks and other issues. If you notice any signs of insect or animal infestation, it is essential to call for water tank cleaning services to prevent water supply contamination.

7. Discoloured Water

Discolored water is another sign that your water storage tank needs attention. If you notice that the water is brown or yellowish, it could indicate rust or corrosion in the tank. Rust and corrosion can lead to leaks and other issues, affecting water quality and supply. Regular cleaning of your tank can help prevent rust and corrosion, extending its life. 


Identifying these signs early can help prevent further damage and ensure your water supply remains clean and reliable. Regular water tank cleaning and maintenance can help prevent these issues, ensuring you have access to clean water for years.
