Clean and safe drinking water is a must. One of the best ways to make sure your water is safe is by cleaning your water tank regularly. Over time, tanks collect debris, sediments, and bacteria, which can affect water quality and even cause health problems.
Whether it’s a ground tank, an underground reservoir, or a rooftop water tank, keeping it clean is vital for both hygiene and safety.
In this guide, I’ll explain the costs. I’ll cover what affects the price and the typical charges for different tank sizes and types. Whether you need a one-time clean or ongoing water tank servicing, understanding the price will help you choose the right service for your needs. You can read more about some unique techniques to clean water tanks.
Factors Influencing Water Tank Cleaning Costs
The cost can vary due to several factors. Understanding these factors will help you get a fair estimate and ensure you’re getting value for your money. Here are the key elements that influence the prices:
Tank Size and Capacity
The size of your water tank plays a big role in determining the cost. Larger tanks require more time and effort to clean. Tanks are usually measured in gallons (USG), and cleaning smaller tanks (500–1,000 USG) will cost less than cleaning bigger ones, like those with a 5,000 USG capacity. The bigger the tank, the more labour and cleaning materials are needed.
500–1,000 USG tanks: AED 600–700
5,000 USG tanks: AED 900–1,200
Tank Location
Where your tank is located affects the cost. Tanks in hard-to-reach spots, like rooftops or underground, need extra equipment and safety measures, which can raise the price. Tanks that are easy to access, like those on the ground, are generally cheaper to clean.
Easy Access: Lower cleaning costs
Difficult Access (rooftops, underground): Higher cleaning costs
Tank Type
The type of water tank you have also impacts the cost. Domestic ground or underground tanks are easier to clean compared to rooftop or overhead tanks, which require specialised equipment and safety measures. For example, rooftop tanks need cleaning from high up, often adding extra charges for tools like scaffolding or ladders.
Ground/Underground Tanks: More affordable
Rooftop/Overhead Tanks: Higher due to accessibility and safety concerns
Condition of the Tank
If your water tank hasn’t been cleaned for a while or has a lot of sediment buildup, the cleaning process will take longer and require more effort. A tank in poor condition might need extra services like disinfection, which can increase the overall cost.
Clean Tanks: Lower cost for standard cleaning
Dirty Tanks: Higher cost for more intensive cleaning
Additional Services
Some cleaning services offer extras, like disinfection, water testing, or sealing to prevent future contamination. These extra services can add to the total cost. For instance, disinfecting your tank to kill bacteria or harmful pathogens might increase the price by a few hundred dirhams.
Standard Cleaning: Includes draining and scrubbing
Disinfection and Water Testing: Additional charges may apply
By understanding these factors, you’ll be able to get a clearer picture of the price. Always ask the service provider for details about your tank’s condition and location to get a more accurate quote for your cleaning service.
Average Water Tank Cleaning Prices in Dubai
The cost can differ depending on the size, location, and condition of your tank. However, here are the average prices you can expect, based on common tank sizes and types:
Domestic Ground or Underground Tanks
For standard domestic tanks, such as ground and underground tanks, the price is usually based on the size and the number of cleaners needed to do the job properly.
500–1,000 USG Tanks: AED 600–700
These smaller tanks typically require two cleaners to finish the job and are the most affordable option.
5,000 USG Tanks: AED 900–1,200
Larger tanks generally need three cleaners and may involve more thorough cleaning due to their size and potential sediment buildup.
Rooftop and Overhead Water Tanks
Rooftop and overhead water tanks are trickier to access, requiring more time, equipment, and safety measures. Because of this, cleaning costs for these tanks are usually higher.
Rooftop Tanks: AED 1,000–1,500
These tanks may need extra equipment like scaffolding, ladders, or cranes to safely access and clean, which raises the overall cost.
Overhead Tanks: AED 1,200–1,700
Overhead tanks also need specialised equipment and may take longer to clean, especially if they are in poor condition, leading to higher prices.
Additional Costs
Besides basic cleaning, some service providers offer extra services such as disinfection, water testing, or even repairs. These services can add extra charges:
Disinfection and Sanitisation: AED 150–300
Disinfecting your tank to eliminate bacteria and harmful organisms can add a small extra cost, depending on the service package you select.
Water Testing: AED 100–200
Some companies offer water testing to ensure your water is safe to drink. This can also increase the total cleaning price.
