Underground water tank cleaning is one of the most important steps to maintaining the quality of drinking water and protecting your family’s health.
Over time, sediments, mud, and bacteria accumulate at the bottom of the tank, leading to water contamination and unpleasant taste or odor.
In Saudi Arabia, where groundwater is a major source of domestic water use, there is an increasing need for regular tank cleaning using safe materials and modern techniques.
That’s where Clean Station, the leading water tank cleaning company in the Kingdom, comes in, offering complete professional solutions for cleaning and disinfecting underground and overhead tanks, ensuring water safety and quality.
Why Regular Underground Tank Cleaning Is Essential
Regular cleaning of your underground water tank is essential for maintaining water quality and protecting your family’s health. Over time, mud, sediments, and algae accumulate at the bottom of the tank, creating an ideal environment for bacteria and harmful microorganisms to thrive.
Neglecting regular cleaning not only leads to water contamination but can also damage your pumps, pipes, and the tank itself.
Key reasons why regular cleaning is essential:
- Removes sediments and algae that build up and pollute the water.
- Prevents the growth of bacteria and parasites that can cause stomach or skin diseases.
- Preserves the natural taste and odor of the water.
- Prevents blockages in pumps and pipes caused by accumulated debris.
- Extends the lifespan of the tank by preventing corrosion and deterioration.
Clean and disinfect your underground tank every 3 to 6 months using safe, approved materials to ensure pure, healthy water for your family all year round.
Professional Steps for Cleaning Underground Water Tanks in Saudi Arabia
Underground water tank cleaning is a precise process that requires specialized equipment and skilled technicians to remove all contaminants without damaging the tank or compromising water quality.
Since many homes and facilities in Saudi Arabia rely on groundwater, regular tank cleaning becomes a necessity rather than an option.
Clean Station offers professional underground tank cleaning and disinfection services, following Saudi Ministry of Health standards and global hygiene protocols.
Here are the professional steps followed by Clean Station’s team:
- Complete Tank Draining: The process starts by completely draining the tank using powerful pumps to remove all sediments and debris from the bottom.
- Initial Inspection: Once empty, the team inspects the tank walls and floor for cracks, leaks, or mold spots that might need special attention.
- Sediment and Algae Removal: Soft, non-abrasive cleaning tools are used to remove mud, algae, and contaminants without damaging the internal surface of the tank.
- Rinsing with Clean Water: After dirt removal, the tank is thoroughly washed with clean water several times to eliminate remaining organic materials.
- Disinfection with Approved Materials: Safe, Ministry-approved disinfectants such as diluted chlorine or eco-friendly bio-cleaners are applied to ensure full bacterial and fungal elimination.
- Final Rinse and Drying: The tank is rinsed again with pure water to remove any traces of disinfectant, then left to dry completely before refilling.
- Refilling with Fresh Water: Finally, the tank is refilled with clean, safe water and tested to confirm quality and purity.
To maintain water purity and prevent contamination, it’s recommended to clean and disinfect your underground tank every 3 to 6 months, especially after sandstorms or water supply interruptions.
Difference Between Cleaning Underground and Overhead Tanks
Although both cleaning processes share the same goal maintaining clean, safe, and high-quality water there are key differences between underground and overhead tanks in terms of cleaning methods, types of contaminants, and required equipment.
Understanding these distinctions helps ensure that each tank is treated properly for optimal hygiene and performance.
Main Differences Between Underground and Overhead Tank Cleaning:
- Ease of Access:
- Overhead tanks are easier to access since they’re located above ground or on rooftops.
- Underground tanks, on the other hand, are buried below ground and require specialized tools for safe entry and deep cleaning.
- Types of Contaminants:
- Underground tanks tend to accumulate mud, sediments, and minerals from groundwater sources.
- Overhead tanks are more exposed to dust, insects, and airborne particles due to their open environment.
- Level of Disinfection:
- Underground tanks need a more intensive disinfection process because high humidity fosters bacterial and fungal growth.
- Overhead tanks typically require lighter disinfection since they are well-ventilated and less likely to harbor organic buildup.
- Tools and Equipment:
- Cleaning underground tanks involves powerful drainage pumps, pressure washers, and safe internal lighting systems.
- Overhead tanks can be cleaned using manual brushes and high-pressure hoses.
- Cleaning Duration:
- Underground tank cleaning takes longer due to accessibility challenges and safety precautions.
- Overhead tank cleaning is usually quicker and more straightforward.
Clean Station assigns dedicated teams for each type of tank, using specialized tools and cleaning methods that ensure effective results without damaging the tank structure or water system.
Expert Tip from Clean Station:
If your property includes both types of tanks, it’s best to clean and disinfect them together to ensure that your entire water supply network remains clean and contaminant-free.
Disinfection Materials Used for Underground Tanks
The disinfection stage is one of the most crucial steps in underground tank cleaning, ensuring that the water remains free from bacteria, fungi, and parasites.
The choice of safe and effective materials is what distinguishes professional companies like Clean Station, which uses Ministry of Health–approved and internationally certified disinfectants.
Here are the main materials used in underground tank disinfection:
- Safe, Controlled Chlorine Solutions:
- Chlorine is one of the most effective agents for eliminating bacteria and viruses, but it must be used in precise, safe concentrations to avoid affecting the taste or safety of the water.
- Clean Station technicians follow international standards for chlorine dilution to ensure maximum sanitation without side effects.
- Biological Oxidizing Agents:
- These eco-friendly oxidizers break down algae, organic residues, and unpleasant odors inside the tank, leaving no harmful chemical traces.
- Non-Toxic Organic Solutions:
- Formulated from natural compounds, these disinfectants effectively kill microorganisms while preserving the water’s natural quality, making them ideal for drinking water systems.
- Ammonia- and Phosphate-Free Cleaners:
- Used in the pre-disinfection stage, these cleaners safely remove dirt and buildup without corroding the tank’s surfaces or contaminating the water.
- FDA and SFDA-Approved Sanitizing Solutions:
- Clean Station uses only products certified by the Saudi Food and Drug Authority to guarantee full compliance with health and environmental regulations.
All materials are biodegradable, non-toxic, and safe for both humans and pets. After each cleaning, Clean Station conducts a post-disinfection water quality test to ensure absolute purity and safety.
How Often Should You Clean Your Underground Tank?
The answer depends on the tank type, location, and water source, but here are the recommended intervals:
General Recommendation:
- Clean and disinfect the tank at least once every 6 months to remove buildup and eliminate bacteria.
For Areas with Salty or Hard Water:
- Clean every 3–4 months, since mineral-rich water accelerates sediment and algae formation.
After Maintenance or Long Periods of Inactivity:
- Always disinfect the tank immediately after repairs or refilling to prevent contamination.
For Commercial Buildings or Healthcare Facilities:
- Clean every 1–2 months, as these facilities have higher water consumption and stricter hygiene standards.
Sticking to a regular cleaning schedule not only preserves water purity but also extends the lifespan of your tank.
Clean Station offers affordable maintenance contracts that include inspection, cleaning, and preventive treatment, all performed by certified professionals.
