Water is a part of everyday life, but we often forget where it comes from before it flows out of our taps. For many homes across Sharjah, that source is a water tank. Over time, these tanks can become a breeding ground for biofilm – a slimy layer caused by algae and sludge buildup. When this happens, the water’s quality drops, and the health risks rise. If you’ve just discovered this problem, acting quickly can make all the difference.

Understanding Water Tank Algae and Sludge
Water tank algae and sludge form when dust, heat, and moisture allow microorganisms to thrive inside the tank. Algae grow on the tank walls where sunlight hits, while sludge forms at the bottom from dirt, rust, or decaying organic material. Together, they create what experts call biofilm – a sticky layer that traps bacteria and contaminants.
- Common signs of this problem include:
- Greenish film or discoloration on tank surfaces
- Foul or earthy smell in stored water
- Slippery tank walls during cleaning
- Reduced water flow from blockages in filters or taps
Ignoring these signs can lead to serious water contamination, affecting not just the taste but also the safety of the water used daily.
Why You Should Act Immediately
When biofilm forms, bacteria multiply faster inside the tank. This can cause illnesses like stomach infections, skin irritation, and other allergic reactions, especially in children or older family members. The longer the issue remains, the harder it becomes to clean the tank properly.
- Leaving water tank algae and sludge untreated can also:
- Corrode the tank material and fittings
- Damage water filters and pipes
- Make cleaning more expensive later
- Force frequent refilling or maintenance
- Acting quickly helps you avoid all of this while maintaining safe, usable water for your family.
First Steps to Take After Discovering Biofilm
Once you notice biofilm or sludge, follow these steps before calling for professional help:
- Stop Water Usage: Prevent contaminated water from entering your household supply.
- Switch Off the Pump: Turn off the motor or pump to avoid spreading the contamination.
- Inspect Safely: Use a flashlight to look for slime, discoloration, or solid buildup.
- Avoid DIY Chemicals: Many household cleaners are not made for water tank surfaces and may leave harmful residues.
- Call a Certified Cleaning Service: Professional cleaners use safe disinfectants and food-grade sanitizers that remove biofilm completely.

Preventing Future Algae and Sludge Growth
Cleaning the tank once isn’t enough. Here are simple habits that help delay future buildup:
- Keep the tank lid tightly closed to block dust and insects
- Schedule regular cleaning every 4-6 months
- Avoid installing the tank under direct sunlight when possible
- Check overflow and inlet pipes for leaks or cracks
- Test the water occasionally to ensure safe quality
You can also refer to local guidelines on water safety from the Sharjah Municipality or other official sources like the World Health Organization. These agencies provide valuable recommendations for household water hygiene.
Why Clean Water Storage Matters
Biofilm buildup doesn’t only affect water taste – it impacts your family’s health and appliances too. Many people don’t realize their water heaters, washing machines, or filters can accumulate debris when tanks are dirty. Over time, this shortens appliance life and increases maintenance costs.
Clean storage is also essential during Sharjah’s summer months, when heat encourages faster bacterial growth. Keeping your tank algae-free saves money, protects your health, and maintains water pressure throughout the household.
When to Call the Experts
Sometimes visual signs of contamination appear mild, but that doesn’t mean your tank is safe. If your water has an odd smell or if it’s been over six months since the last cleaning, it’s time to book a professional inspection.
