AWWA C600 Water Main Hydrostatic Test Report

It captures the information needed to document acceptance testing of a new water main, including the test segment, pipe details, test pressure, two-hour hold, leakage observations, and final result. It is designed for field use so the inspector can record what was tested, what was observed, and whether the segment met the acceptance criteria. It also leaves room for deficiencies and corrective actions when the test does not pass.

Use it after installation and before the water main is placed into service, when the segment has been isolated, restrained, and prepared for hydrostatic testing. It is appropriate for acceptance testing of new mains and extensions where the project specification or utility standard requires a documented pressure test. It is not a general maintenance checklist or a leak repair log.

The report is typically completed by the inspector, utility representative, or contractor quality lead who is present for the test and can verify the readings firsthand. The contractor representative should be identified on the form, and the person signing off should be the one who observed the test or reviewed the documented evidence. If your utility requires witness testing, the witness should be named in the identification section.

It is usually completed for each test segment, not as a recurring calendar inspection. Every new section of water main that is isolated for acceptance testing should have its own report so the test date, pressure, leakage calculation, and result are tied to a specific segment. If a segment is retested after repairs, create a new record or clearly note the retest event.

Yes, it is structured around the core elements commonly documented for AWWA C600 hydrostatic acceptance testing: segment identification, test setup, pressure hold, leakage measurement, and acceptance decision. It helps you capture the evidence needed to show that the test was performed under the required conditions. If your utility, engineer, or AHJ adds stricter requirements, customize the fields to match those project specifications.

The most common issues are missing segment limits, incomplete pipe and fitting details, uncalibrated or unverified gauges, and unclear start/end pressure records. Another frequent problem is documenting observed leakage without showing the allowable leakage calculation used to judge acceptance. This template keeps those items together so the pass/fail decision is traceable.

Yes, and it should be. Different materials, diameters, lengths, and utility standards may change the test setup, allowable leakage calculation, or supporting notes you need to capture. Add custom fields for disinfection status, flushing, restraint verification, or witness signatures if your project requires them.

It works well as a mobile field form because the sections follow the order of the actual test: identification, readiness, execution, calculation, and sign-off. You can attach gauge photos, leak photos, calibration records, and corrective action notes directly to the report. That makes it easier to review, export, and archive with the project closeout package.
