Water tanks are widely used across various industries for transporting water and other liquids to their designated locations or filling stations. The construction and materials used for these tanks depend on the type of liquid being transported and the specific needs of the customers.
Common materials used for building water tanks include aluminium, carbon steel, stainless steel, and fibreglass-reinforced plastic, as they can effectively transport and store water and other liquids for an extended period of time.
Water tanks are used daily, and without proper maintenance, they can malfunction and become unusable, leading to costly disruptions in daily operations. In this guide, we will discuss preventive maintenance tips for water tanks to ensure that they remain in optimal condition and that the water within remains hygienic and safe for consumption.
Regular Inspection
The first step in maintaining your water tank is scheduling regular inspections. These inspections will help identify any potential issues or damage to the tank, such as cracks, leaks, or corrosion. Inspecting your water tanks at least twice a year is recommended, with one comprehensive inspection conducted by a professional.
During the inspection, check for the following:
- Structural Integrity: Inspect the tank’s exterior and interior for any signs of damage, such as cracks, bulging, or corrosion. Pay close attention to the seams and joints of the tank, as these are common areas for leaks to develop.
- Roof and Vents: Ensure that the roof of the tank is in good condition and free from any debris, such as leaves or dirt. Check that the vents are clear and functioning correctly to prevent water contamination by pests or foreign objects.
- Pipes and Fittings: Inspect all pipes and fittings connected to the tank for any signs of leaks, corrosion, or damage. Make sure all connections are secure and tight to prevent any water loss.
Cleaning and Disinfection
Over time, sediment, algae, and other debris can accumulate at the bottom of the tank, leading to the growth of bacteria and other microorganisms. Regular cleaning and disinfection of your water tank are crucial to maintain the quality of the water and prevent any health risks.
Firstly, drain the tank entirely and use a high-pressure hose to clean the interior of the tank, removing any sediment and debris. For stubborn dirt, use a non-toxic, non-abrasive cleaning agent to scrub the interior surfaces of the tank. Ensure that the tank is thoroughly rinsed to remove any traces of the cleaning agent before refilling.
After cleaning, disinfect the tank using a chlorine-based solution. The recommended concentration is 50 ppm (parts per million) of available chlorine.
Fill the tank with water and allow the solution to sit for a minimum of 12 hours to ensure complete disinfection. Afterwards, drain the tank and refill it with clean water.
Monitor Water Quality
Regular testing of the water quality in your tank is essential to ensure that it remains safe for consumption. Test for the following parameters:
- pH Levels: The pH of the water should be between 6.5 and 8.5 to prevent corrosion and scale formation in the tank.
- Total Dissolved Solids (TDS): High TDS levels can indicate the presence of contaminants in the water, such as heavy metals, salts, or minerals. The acceptable TDS level for drinking water is below 500 ppm.
- Microbial Contamination: Test for the presence of harmful bacteria, such as E. coli or coliform, to ensure that the water is safe for consumption.
Fix Leaks and Repair Damage
If you notice any leaks or damage to your water tank during the inspection, it is crucial to address these issues promptly. Small cracks or leaks can be sealed using a waterproof sealant or epoxy.
For more extensive damage, it may be necessary to consult a professional for repairs or even consider replacing the tank altogether.
Conclusion
Preventive maintenance of water tanks is crucial to ensure their longevity and maintain the quality of the water stored within. By following this guide, you can take proactive steps to keep your water tank in optimal condition and ensure that the water remains safe and hygienic for consumption.
Regular inspections, cleaning and disinfection, water quality monitoring, and addressing any damage promptly are all essential components of a comprehensive preventive maintenance plan for water tanks.
