Introduction
Living in Dubai, I quickly realised just how precious water is. Many of us rely on underground water tanks to store it, especially when the municipal supply isn’t always reliable. These tanks are an essential lifeline for homes, offices, and businesses. But over time, dirt, bacteria, and sediment can build up inside. This not only affects the water’s quality but can also cause serious health risks.
That’s why underground tank cleaning is so important. It’s not just about keeping things clean—it’s about making sure your water is safe and your tank lasts longer. In this article, I’ll walk you through why underground tank cleaning matters, how the cleaning process works, and how you can benefit from professional water tank cleaning services.
Why Underground Water Tank Cleaning Is Essential
I’ve learned that cleaning underground water tanks is often something we forget about, but it’s a key part of keeping our water supply safe and healthy here in Dubai. Over time, things like dirt, bacteria, and other contaminants can gather, affecting both the water quality and the tank’s performance. Here’s why it’s so important to clean your underground water tank regularly:
Preventing Health Hazards and Waterborne Diseases
Stagnant water in a dirty tank can quickly turn into a breeding ground for harmful bacteria, algae, and mould. These can contaminate your water and pose serious health risks. Regular cleaning helps clear out these harmful organisms, reducing the risk of waterborne diseases like cholera, dysentery, and gastroenteritis.
Improving Water Quality and Taste
If you don’t clean your tank, things like sediment, debris, and mineral build-up can make the water taste unpleasant and look cloudy. A clean tank ensures your water stays fresh, clear, and free of unwanted particles, improving both the taste and the overall quality of everyday use.
Extending the Lifespan of Your Tank
Just like any system, water tanks need upkeep to function properly. Regular cleaning helps remove debris and prevents rust or corrosion from forming. This means your tank will last longer and work more efficiently, providing you with a reliable source of clean water.
By regularly cleaning your underground water tank, you’re not just protecting your health but also ensuring that your water system stays in great condition for years to come.
Common Contaminants Found in Underground Water Tanks
When I first learned about underground water tanks, I didn’t realise how easily they could become contaminated. Over time, a variety of substances can build up in the tank, affecting the water’s quality if not cleaned regularly. Here are some of the most common contaminants that can be found in underground water tanks:
Sediment and Debris
Dirt, sand, and debris can gather at the bottom of the tank, often brought in from the water source or the surrounding environment. Rainstorms or strong winds can make this worse. While small amounts of sediment aren’t harmful, too much can cloud the water, block pipes, and affect the water flow.
Bacterial Growth and Algae Formation
Stagnant water in an underground tank is the perfect environment for bacteria to grow. Harmful bacteria like E. coli and Legionella can thrive if the tank isn’t cleaned regularly, leading to serious health risks. Algae can also form, especially if the water is exposed to sunlight or if organic matter builds up.
Chemical Residues and Mineral Deposits
Chemicals from things like cleaning products, pesticides, and fertilizers can seep into the tank, contaminating the water. On top of that, hard water can leave behind mineral deposits like calcium and magnesium, which form scale on the tank’s walls and floor. This not only affects water quality but can also reduce the tank’s efficiency.
Fungi and Mold
Excess moisture and organic material inside the tank can lead to the growth of fungi and mould. These can make the water smell bad, harm its quality, and even cause health problems if inhaled or consumed.
Rust and Corrosion
Metal tanks or those made from other materials that are prone to rust can suffer from corrosion, especially if sediment and debris are left to build up. Rust can contaminate the water, making it unsafe to drink and damaging the tank over time.
Regular underground tank cleaning is essential to prevent these contaminants from affecting your water. By cleaning your tank, you can keep your water safe, fresh, and ready for daily use.
The Underground Water Tank Cleaning Process
Cleaning an underground water tank is a multi-step process that requires precision and specialized tools to ensure the removal of contaminants and the restoration of water quality. Here’s an in-depth look at how professionals approach this important task:
Initial Inspection and Assessment
Before the cleaning begins, a thorough inspection is performed to assess the condition of the water tank. This includes:
- Checking the structural integrity of the tank to identify cracks, leaks, or damage that could affect the cleaning process or the water quality.
- Evaluating the water quality to determine the type of contaminants present and their potential health risks.
- Identifying the type of tank (e.g., concrete, fibreglass, metal) to ensure the appropriate cleaning techniques are used.
The goal of this inspection is to understand the specific needs of the tank and to ensure the cleaning process will be effective and safe.
Draining the Tank
The first major step in cleaning the underground water tank is draining the existing water. This is done in a controlled and systematic manner:
- A submersible pump or similar equipment is used to remove the water from the tank. The water is typically pumped into a safe drainage system to avoid contamination of surrounding areas.
- Water disposal is carried out by environmental regulations to ensure no harm is done to the environment or local water systems.
Draining the tank is essential because it provides full access to the tank’s interior and ensures that any contaminants, such as sediment and bacteria, are effectively removed.
Removing Sediment and Debris
Once the tank is emptied of water, the cleaning crew focuses on removing any accumulated sediment, dirt, and debris that may have settled at the bottom. This debris often consists of:
- Sand and silt from water enter the tank.
- Leaves, twigs, and other organic material may have made their way into the tank through cracks or vents.
- Rust and corrosion from the tank’s structure if the tank is made of metal.
Professional cleaning equipment such as vacuum pumps or manual tools are used to thoroughly clean the tank’s floor and walls. The goal is to remove all large particles that could block pipes or damage the tank’s components. This step also prevents the growth of harmful bacteria that thrive in stagnant debris.
Scrubbing the Tank Interior
After debris removal, the interior surfaces of the tank are scrubbed to eliminate any remaining grime or deposits. This step is critical in ensuring the tank is thoroughly cleaned and free from contaminants.
- Stiff brushes and scrapers are used to scrub away dirt, algae, and any stubborn stains that have formed on the walls and floor of the tank.
- For tanks with mineral buildup, like calcium or magnesium deposits, special descaling agents are applied to dissolve these mineral deposits effectively.
Scrubbing not only ensures the removal of visible dirt but also helps dislodge any contaminants that may have adhered to the surface of the tank, preparing it for disinfection.
Disinfection of the Tank
Once the tank is scrubbed, disinfection is performed to kill any remaining harmful microorganisms such as bacteria, fungi, or viruses. The disinfection process involves:
- Applying an appropriate disinfectant, such as chlorine or other eco-friendly options, to the interior surfaces of the tank. The disinfectant is left to sit for a specific amount of time to ensure thorough sterilization.
- Special care is taken to sanitize the tank’s pipes and vents to prevent contamination from spreading into the water supply.
This step is vital to prevent future bacterial or fungal growth and to ensure that the water stored in the tank is safe for consumption. After disinfection, the tank is typically left to dry for a short period before the next step.
Rinsing and Flushin
Following disinfection, the tank is thoroughly rinsed with clean water to remove any residual disinfectant and debris. This step is crucial to ensure that no chemicals or cleaning agents remain in the tank that could potentially contaminate the water supply.
- The tank’s walls and floor are flushed with water to ensure any remnants of the cleaning agents are completely washed away.
- Additionally, the pipes and drainage system are flushed to ensure there are no remaining contaminants that could affect the quality of the water.
Rinsing ensures that the tank is clean and free of harmful substances, leaving it ready to store fresh water.
Final Inspection and Quality Assurance
Once the cleaning process is complete, a final inspection is conducted to ensure the tank is entirely clean, sanitized, and in good condition.
- The tank is checked for any remaining debris, stains, or mineral buildup.
- The tank’s structure is examined to ensure no damage has occurred during the cleaning process and that it is secure and watertight.
- If necessary, water quality tests are conducted to ensure that the water meets the required standards for consumption.
If everything passes the inspection, the tank is deemed ready for use again.
Refilling the Tank
After a thorough inspection and approval, the tank is refilled with fresh water. This is typically done through the existing water supply system.
- The water is allowed to settle to ensure that no debris or contaminants from the refilling process enter the tank.
- Once the tank is full, the system is checked for proper flow and function, ensuring that the water is stored efficiently and securely.
Maintenance Tips and Recommendations
Upon completion of the cleaning, most professional services offer maintenance tips to keep the tank in good condition. Recommendations may include:
- Scheduling regular cleaning every 6 to 12 months.
- Keeping the tank sealed and ensuring no external debris can enter.
- Checking for leaks and damage periodically.
- Installing filters to reduce sediment and debris buildup.
These tips help maintain the quality of the water and extend the lifespan of your underground water tank.
