AWWA C600 Water Main Hydrostatic Test Report

Inspection template for documenting acceptance testing of a new water main in accordance with ANSI/AWWA C600, including a two-hour hydrostatic hold at test pressure, allowable leakage calculation, observed leakage, and inspector sign-off.

Test Identification

• Project name and test segment identified
  Record the project name, test location, pipe segment limits, and stationing or drawing reference.
• Test date and start time recorded
  Document when the hydrostatic test began.
• Inspector and contractor representatives identified
  Record names and roles of the inspector, contractor representative, and any witnessing authority.

Main and Test Segment Details

• Pipe material, diameter, and length recorded
  Document pipe material, nominal diameter, and total test length for the segment.
• Appurtenances and fittings included in test segment
  Select all items included in the test section.
• Test section isolated and restrained
  Verify the main is isolated, restrained, and ready for pressure testing without unintended movement.

Pre-Test Readiness and Safety

• Test equipment calibrated and suitable for test pressure
  Verify gauges, pumps, hoses, and fittings are in serviceable condition and appropriate for the required pressure range.
• Test pressure gauge reading recorded
  Record the stabilized gauge reading used for the test.
• Work area controlled and safe for inspection
  Verify access control, traffic control, and PPE are in place; no unsafe conditions are present during pressurization.

Hydrostatic Test Execution

• Test pressure maintained for required two-hour hold
  Confirm the main was held at the specified test pressure for a continuous two-hour period in accordance with the acceptance procedure.
• Start and end pressure recorded
  Document the pressure at the start and end of the hold period, including any observed fluctuations.
• Observed leakage during hold
  Record the measured leakage observed during the test hold period.

Leakage Calculation and Acceptance

• Allowable leakage calculated and documented
  Record the allowable leakage calculation used for the test, including the basis and any formula inputs.
• Observed leakage within allowable limit
  Confirm the measured leakage did not exceed the allowable leakage for the test segment.
• Test result accepted
  Mark whether the water main hydrostatic test is accepted based on pressure hold and leakage criteria.

Deficiencies, Corrective Actions, and Sign-Off

• Deficiencies or non-conformances documented
  Record any leaks, pressure loss, equipment issues, or other non-conformances observed during the test.
• Corrective actions completed or scheduled
  Describe repairs, retesting requirements, or follow-up actions needed before acceptance.
• Inspector signature
  Inspector signs to confirm the record is complete and accurate.
