DA Form 5457: Potable Water Container Inspection Guide – Ensuring safe drinking water in the field is a critical mission for U.S. Army units. DA Form 5457, officially titled Potable Water Container Inspection, is the primary document used by Preventive Medicine (PVNTMED) inspectors and Field Sanitation Teams to verify that water storage and transport containers meet strict safety standards.
This article explains the purpose of the form, how to complete it, key inspection criteria, and why it matters for operational readiness and soldier health.
What Is DA Form 5457?
DA Form 5457 (November 2005) is a standardized checklist for inspecting various types of potable water containers. It is authorized for use under TB MED 577 (Sanitary Control and Surveillance of Field Water Supplies), with the Office of The Surgeon General as the proponent.
The form covers:
- Section I: Water Trailer Inspection Criteria
- Section II: Water Tank Truck Inspection Criteria
- Section III: Fabric Tank/Drum Inspection Criteria
- Section IV: Container Location (Field Use) Inspection Criteria
It documents container condition, site setup, water quality indicators (such as chlorine residual), and inspector findings. A completed and signed DA Form 5457 (typically valid for up to 6 months when signed by PVNTMED) allows units to perform routine monthly inspections themselves.

Why Proper Potable Water Container Inspection Matters?
Contaminated water can quickly lead to gastrointestinal illness, dehydration, and reduced combat effectiveness. DA Form 5457 helps prevent:
- Bacterial, viral, or chemical contamination
- Cross-connection with non-potable sources
- Equipment failure that could compromise water safety
PVNTMED teams and unit personnel use this form to maintain compliance with Army water sanitation standards, protecting troops in garrison, training, and deployed environments.
Key Inspection Criteria on DA Form 5457
1. Water Trailers (e.g., “Water Buffalos”)
- Exterior: Marked “POTABLE WATER ONLY,” clean and in good repair.
- Manhole Covers: Gaskets intact, locking mechanisms functional, pressure relief valve operates.
- Dispensing Spigots: All function, T-handle operates easily, protective box and locks intact.
- Drain: Plug installed hand-tight, no cracks exposing fiberglass.
- Interior: Clean, no rust (for stainless steel/aluminum), no excessive cracks/chips (for fiberglass).
2. Water Tank Trucks
Similar checks apply, with emphasis on:
- Hose coupling threads undamaged
- Dust caps attached
- Tank interior free of rust and properly maintained (steel/aluminum not painted inside)
3. Fabric Tanks/Drums
- Exterior clean and marked properly
- Plugs/patches secure
- Valve assembly (check-valve adapter, coupler, dust cap) in good condition
4. Field Location (Site Conditions)
- Manholes/parts closed
- Soakage pits under spigots
- No pollution sources nearby
- Adequate chlorine residual documented (in ppm)
- Water source clearly identified
Inspectors mark YES/NO for each item and provide comments/recommendations. The form requires the printed name, grade, and signature of the PVNTMED inspector.

Units should prepare containers (cleaning per local guidance) before requesting PVNTMED certification.
Best Practices and Compliance
- Perform inspections before use and routinely (monthly for trailers with current PVNTMED sign-off).
- Maintain records for audits and continuity.
- Train Field Sanitation Team members on basic checks while relying on PVNTMED for formal certification.
- Address deficiencies immediately — do not use non-compliant containers.
For full technical guidance, refer to TB MED 577 (available via official Army channels).
DA Form 5457 is an essential tool in the Army’s preventive medicine program. Proper use ensures that every soldier has access to safe, potable water — a fundamental requirement for mission success and force health protection.
