When commissioning a cold water system, what indicates readiness for handover?

• A. Documentation is filed but no tests performed.
• B. System shows acceptable pressure and flow but no documentation.
• C. All required handover documentation is provided, and the system passes tests for pressure, flow, leaks, and contamination controls.
• D. Only a visual inspection is completed.

Answer: (C)

Readiness for handover means the system isn’t just working, it’s also verifiably compliant and ready for ongoing operation. That requires two things: complete, organized handover documentation and proven performance through formal tests.

The best choice reflects that. It says all required handover documentation is provided and the system has passed tests for pressure, flow, leaks, and contamination controls. That combination shows the project has been properly checked, records are in place for future maintenance, and the system meets the design and safety requirements. The pressure and flow tests confirm the system can deliver what it’s supposed to under real conditions. Leaks tests ensure there are no hidden faults that could cause water loss or damage. Contamination-control tests verify the water remains safe and within accepted quality limits, which is crucial for any cold water supply.

Other options fall short because they skip essential parts of the handover readiness. Documentation without tests means you have no verified proof the system performs as designed. Tests without documentation leave you with results but no official records to rely on for maintenance, warranties, or future compliance. A visual inspection alone checks appearance but does not prove performance, safety, or water quality.

So, providing the full set of handover documents plus passing all relevant performance and safety tests is what truly indicates readiness for handover.
