Inspection and Test Plan for Method Statement: Hydrostatic Pressure Testing of Water Mains

AI-assisted inspection and test plan connected to a method statement, with PDF and Excel export.

Published 03 Jul 2026 Rev. 00 2 views
About this ITP: This ITP defines inspections, witness/hold points, acceptance criteria, and records for hydrostatic pressure testing of water mains.

More than a static template

Unlike a downloadable Word or PDF template, this ITP is an AI-assisted editable starting point directly connected to its method statement. Every inspection activity, hold point, and acceptance criterion is structured and ready to adapt to your project.

  • AI-assisted customization — Tailor inspection activities and acceptance criteria to your specific project scope.
  • Linked method statement — This ITP is connected to the corresponding method statement describing the work sequence.
  • Multiple export formats — Download as a formatted PDF or editable Excel spreadsheet.
  • Editable starting point, not a final document — Review and verify all content against your project specifications and standards before use.

What you can customize

When you save this ITP to your account, every inspection row becomes editable. You can add, remove, or modify:

  • Inspection activity — Description of what is being inspected.
  • Inspection type — Hold point (H), Witness point (W), Review (R), or Monitor (M).
  • Responsibility — Contractor, subcontractor, engineer, or client.
  • Frequency — How often the inspection occurs.
  • Acceptance criteria — Referenced standard or specification requirement.
  • Records — Forms, test reports, or checklists required as evidence.

Why this ITP is used

To ensure water mains meet structural integrity and tightness requirements before commissioning.

Who uses this inspection and test plan

Contractor testing team, QA/QC, HSE, and the Client/Engineer for witnessing and acceptance.

When this ITP is prepared and submitted

After installation and curing of restraints, prior to disinfection and commissioning.

Who receives or approves this ITP

Engineer/Client Representative

Inspection scope

Covers document review, setup inspection, flushing/air removal verification, staged pressurisation, hold test with leakage measurement, controlled depressurisation, and acceptance.

Typical hold, witness, and review points

HP1 – Pre-test setup; HP2 – Establish test pressure; HP3 – Acceptance review and certification.

Typical inspection records

Approved method/ITP, calibration certificates, pressure/temperature logs, make-up water logs, leakage calculations, permits, checklists, acceptance certificate.

Important approval note

This ITP is an AI-assisted editable starting point, not a pre-approved document. Before use on any project, all inspection activities, hold points, and acceptance criteria must be reviewed and approved by the relevant parties (superintendent, principal contractor, or client representative) in accordance with your contract and project quality plan.

Always verify acceptance criteria against your applicable drawings, specifications, and regulatory requirements. Hold points must be confirmed with the relevant authority before work proceeds past that point.

Inspection and test plan

Activity Inspection / Test Acceptance Criteria Responsibility Record
Test package review and approvals Method/ITP approved; calibrations in date; permits in place All documents approved prior to site works QA/QC Engineer / Engineer Approved MS/ITP; calibration certs; PTW; WIR
Pre-test site inspection (HP1 – Hold Point) Restraints, test ends, air valves, valves status, backfill, barricades, discharge plan Conformity with prerequisites; HP1 signed by Engineer Testing Supervisor / Engineer HP1 checklist; photos
Flushing and air removal verification Achieved flushing velocity; air expulsion at high points Clear water; no air observed at vents Testing Supervisor / QA/QC Flushing log; air removal checklist
Instrumentation set-up and calibration check Gauge/transducer ranges & accuracy; logger time sync Calibrations valid; instruments functional Testing Supervisor / QA/QC Calibration certs; instrument checklist
Staged pressurisation 50% and 75% holds pre-full pressure Stable trends; no leaks Testing Supervisor Logger data; supervisor notes
Establish test pressure (HP2 – Witness) Full test pressure achieved at highest point Within +0/−5% of specified test pressure Testing Supervisor / Engineer HP2 witness sheet; readings
Hold period and leakage measurement 2-hour hold (typ.); make-up volume measurement; continuous pressure/temperature logging No visible leaks; leakage within allowable per governing standard; pressure stability within specified band [Verify] Testing Supervisor / QA/QC Make-up log; pressure/temperature CSV; plots
Depressurisation and discharge control Controlled bleed-down; permitted discharge; dechlorination if required No surge events; discharge within permit limits Testing Supervisor / HSE Discharge log; permits
Acceptance and close-out (HP3 – Hold Point) Review results and calculations Meets acceptance criteria; test certificate signed Engineer / QA/QC Signed acceptance certificate; final report

Frequently asked questions

Approved method/ITP, valid calibrations, permits/consents, pre-test checklist, and section isolation drawings.

Maintain constant pressure during the hold and measure total make-up water with a calibrated device, then compare the rate to the allowable limit per the governing standard.

Only if the project standard allows a pressure-decay method with defined acceptance limits. Otherwise use the make-up water method per AWWA/EN. [Verify per project specifications]
