Commissioning and Acceptance Testing for Data Center Water Tanks

Commission and accept a data center water tank with a defined sequence: review the factory 1500 V holiday-test record, verify bolt torque and joint prep, perform a controlled fill test against a leakage criterion, document the hydro test where required, and close a punch list before handover. A well-documented commissioning gives the owner a clean baseline and the inspector a clear acceptance path for both fire and potable duty.

Before the Water Goes In

Commissioning starts with records, not water. Review the factory 100% 1500 V holiday-test record tied to your panel numbers, confirm bolt torque and joint cleanliness, and verify the roof and appurtenances are fitted. Catching a missing test record here prevents accepting an unverified lining.

The Fill and Leakage Test

A controlled fill test watches the shell as the level rises, checking joints and the floor for weeping against an agreed leakage criterion. Bolted tanks are expected to be leak-tight at the sealant joints; any weep is addressed at the joint, not by coating the whole shell.

• Fill in controlled stages.
• Watch joints and floor.
• Weep addressed at the joint.

Hydro Test and Punch List

Where the design calls for a hydrostatic test, it is performed and documented. The punch list closes out appurtenances, access, labeling and any minor items before handover. For potable duty, the hygiene and NSF 61 lining documentation is confirmed at this stage.

• Hydro test if required.
• Close punch list.
• Confirm potable lining docs.

Documentation and Baseline

Handover should include the coating test record, torque log, fill/leakage result, as-built drawings and the inspection sign-off. Large tanks show the discipline this requires: the Italy Sardinia 30,549 m3 process-water tank (2025, enamel roof) and the Indonesia Cilincing 21,088 m3 potable tank (2024, aluminum dome) are delivered at scales where QA rigor is non-negotiable.

• Italy Sardinia 2025: 30,549 m3, enamel roof.
• Indonesia Cilincing 2024: 21,088 m3, aluminum dome.
• QA rigor scales with volume.

Company Expertise

Center Enamel operates under ISO 9001 QA with 100% 1500 V holiday testing and documented handover, so a data center tank commissioning produces the coating record, torque log and test results an owner and inspector expect.

Frequently Asked Questions

What is checked before filling?

The 1500 V holiday-test record by panel, bolt torque, joint cleanliness and roof fit - records first, water second.

How is leakage judged?

A controlled fill test watches joints and floor against an agreed leakage criterion; weeps are fixed at the joint.

Is a hydro test always required?

Where the design or code calls for it, yes; it is performed and documented as part of acceptance.

What documents should handover include?

Coating test record, torque log, fill/leakage result, as-builts and inspection sign-off.

How is potable duty confirmed?

The NSF 61 lining documentation and hygiene measures are confirmed at commissioning.

Are large tanks commissioned differently?

The same sequence, with more rigor - as seen on the 30,549 m3 Italy Sardinia and 21,088 m3 Indonesia Cilincing tanks.

Conclusion

Commissioning is the owner's first and best protection: review the coating test record, verify the bolts and joints, fill against a leakage criterion, close the punch list, and keep the documentation. A disciplined handover turns a built tank into an accepted, baselined asset for both fire and potable duty.
