  • Regular cleaning of domestic water tanks is essential to ensure potable water safety, as over time tanks can accumulate sediment, sludge, rust, and microbial buildup. Our comprehensive cleaning process involves isolating and draining the tank, removing sludge and sediment, manually scrubbing internal surfaces, performing high-pressure water jet cleaning, properly disposing of wastewater, and completing a final rinse before refilling.

    All confined space work is conducted in full compliance with Singapore’s Workplace Safety and Health (Confined Spaces) Regulations, including gas testing, ventilation setup, and safety supervision. We provide these services for MCST-managed condominiums, commercial buildings, industrial facilities, and landed residential properties.

  • Detailed internal condition checks to detect corrosion, cracks, leaks, or structural concerns.

    We provide clear documentation with photo evidence for property managers and MCST records.

    Inspections support preventive maintenance planning and regulatory compliance documentation.

  • After cleaning, water tanks are disinfected using approved disinfecting agents that are suitable for potable water systems. Our sterilisation process involves the application of an approved disinfectant solution, careful monitoring of the required contact time, final flushing and neutralisation where necessary, and conducting water quality safety checks. This ensures compliance with Singapore’s public health standards and helps minimise bacterial risks in stored water. Sterilisation is especially critical after repair works, new installations, contamination incidents, and as part of routine preventive maintenance.

  • In Singapore, building management bodies often require proper inspection records and maintenance documentation to ensure regulatory compliance and operational accountability. Our certification services include the issuance of inspection reports, cleaning and sterilisation completion documentation, detailed condition assessment summaries, and before-and-after photo records. This provides building owners and managing agents with comprehensive documentation for audit reference and compliance purposes.

  • We provide comprehensive installation services for new and replacement domestic water tanks across residential, commercial, and industrial properties. Our scope of work includes site assessment and preparation, removal of existing tanks (if required), installation of the new tank system, pipe connection works, valve and control setup, as well as full testing and commissioning. Each installation is completed with post-installation cleaning and sterilisation to ensure hygiene and system readiness. All works are carried out in accordance with Singapore building and safety standards, ensuring safe, compliant, and reliable operation.

  • Early detection and timely repair of water tank issues are essential to prevent costly system failures and water supply disruptions. Our repair services include leak rectification, internal coating repairs, structural crack repairs, valve replacement, float system adjustments, rust treatment, and access cover replacement. In addition to corrective works, we offer scheduled preventive maintenance programs to help buildings maintain proper hygiene standards, structural integrity, and reliable system performance over the long term.
