DA Form 4374: Water Supplementary Operating Log Guide

DA Form 4374: Water Supplementary Operating Log Guide – DA Form 4374, titled Repairs and Utilities Operating Log (Water—Supplementary), serves as a supplementary daily or periodic log for water supply and treatment operations at Army installations. It complements the general water operating log (such as DA Form 4141) by capturing additional metrics needed for comprehensive monitoring, reporting, troubleshooting, and compliance.

It helps document variables like chemical usage, specific treatment processes, supplementary readings, maintenance notes, or unusual conditions not covered in primary logs. This supports efficient, safe, and regulatory-compliant water system management.

Purpose and Importance in Army Facilities Management

The form ensures accurate record-keeping for water utilities, which is critical for:

  • Regulatory Compliance — Meeting federal, state, local, and DoD/EPA standards for potable water quality and system operations.
  • Operational Efficiency — Tracking trends in water production, treatment effectiveness, and resource consumption.
  • Maintenance and Troubleshooting — Recording anomalies, repairs, or supplementary data for predictive maintenance.
  • Reporting — Feeding into monthly operating reports (MORs), annual summaries, and audits.

Proper use supports Army goals for reliable, cost-effective, and environmentally sound utility services under facilities engineering programs.

DA Form 4374 is prescribed in AR 420-49, Utility Services (28 April 1997, with historical context). This regulation consolidates policies for water supply, wastewater, and other utilities.

Key related documents include:

  • AR 420-1, Army Facilities Management — Current overarching guidance on utility services, water supply, and recordkeeping.
  • UFC 3-230-02, Operation and Maintenance: Water Supply Systems — Provides technical details on logs, monthly reports, and supplementary data for water treatment plants.
  • DA Form 4141 (Water—General) as the primary companion log.

Installations must maintain records for surveillance, treatment, and distribution systems.

How to Fill Out DA Form 4374?

While specific block-by-block instructions are in associated technical manuals or local SOPs, typical entries include:

  • Date, Time, and Shift — For each log entry.
  • Operational Parameters — Supplementary readings such as chemical dosages, filter performance, or secondary meter data.
  • Water Quality Metrics — Additional test results or treatment notes.
  • Maintenance/Repairs — Notes on issues, actions taken, or equipment status.
  • Operator Signature — Certification by qualified utility plant personnel.

Operators must be properly certified. Data from this form feeds into broader reporting requirements. Always follow your installation’s Director of Public Works (DPW) procedures and current UFC/AR guidance.

Tip for Users: Digital tools or integrated facilities management systems may supplement or replace paper forms at modern installations, but the core data requirements remain.

Best Practices for Water Utilities Logging

  • Perform daily entries and compile into monthly reports for trend analysis.
  • Cross-reference with general logs (e.g., DA Form 4141) and lab results.
  • Retain records per Army retention policies for audits and compliance.
  • Integrate with Installation Utility Management Plans and emergency response procedures.
  • Train personnel on accurate, timely documentation to support safety and efficiency.

Where to Obtain DA Form 4374?

Visit the official Army Publishing Directorate (APD) website or your installation’s DPW/forms repository for the latest version. Search for “DA Form 4374” on armypubs.army.mil or contact your local public works office.

Ensure you use the current edition aligned with AR 420-1 and UFC standards.

Conclusion: Supporting Reliable Army Water Systems

DA Form 4374 plays a vital supporting role in Army water utilities management. Accurate logging ensures compliance, operational excellence, and resource stewardship at U.S. military installations. Facilities and public works teams should stay updated with AR 420-1, UFC 3-230-02, and local policies for optimal results.

For installation-specific guidance, consult your DPW or garrison utilities manager. Proper use of this form contributes directly to mission readiness and the health/safety of Army communities.
