In Singapore, maintaining the cleanliness and safety of water storage systems is crucial due to the stringent guidelines set by the Public Utilities Board (PUB). These regulations help ensure high water quality, especially for potable water tanks. Drawing on our extensive industry experience, this guide will provide insights into effective water tank cleaning and maintenance practices to help you remain compliant and keep your system in optimal condition.
1. Annual Maintenance Requirements for Potable Water Tanks
Property owners with potable water storage tanks are required by law to have these tanks cleaned, inspected, and certified at least once every 12 months by a Licensed Plumber (LP). This includes:
- Inspection: Assessing the tank for any signs of wear, corrosion, or contamination.
- Cleaning and Disinfection: Removing contaminants and disinfecting to prevent waterborne diseases.
- Certification: Providing documentation to confirm the tank meets safety and hygiene standards.
2. Non-Potable Water Tanks: Rainwater, Sprinkler, and Hose Reel Systems
Non-potable tanks, such as those used for rainwater harvesting, sprinkler systems, and hose reels, do not fall under the same annual cleaning and certification requirements. However, regular maintenance is essential to ensure these systems are free from blockages and remain operational. Regular inspection can help identify any issues early, preventing potential system failures.
3. Skilled Cleaners and Maintenance Expertise
The role of experienced cleaners cannot be underestimated. Ensuring that the team cleaning your tank is skilled in techniques such as balancing water pressure across compartments is vital for long-term durability. Proper handling during cleaning helps prevent stress on tank walls and extends the life of your water storage tank.
