Legionnaires’ disease is a serious form of pneumonia caused by bacteria that thrive in stagnant or improperly heated water systems.

Regular temperature checks and flushing regimes are the primary defense against bacterial growth.

These PDF forms range from simple temperature monitoring sheets to detailed maintenance logs that track descaling and cleaning activities.

Below is a detailed guide to the 5 unique layouts included in this free download.

1. Legionella Log Sheet Template-1

Best for: Comprehensive water management.

This template is designed for tracking multiple control measures in one place.

Maintenance Tracking: It includes a dedicated column for “Clean & De-scaling”, which is essential for showerheads and taps where scale buildup can harbor bacteria.
Combined Time/Date: The first column captures “Date & Time”, keeping the entry compact.
Full Monitoring: It tracks “Cold Water Temp,” “Hot Water Temp,” and “Water Flush”, covering the three main pillars of Legionella control.

Best for: Routine temperature and flush checks.

This is a cleaner, simplified log designed for daily or weekly monitoring.

Header Info: It features a field for “MONTH” at the top, helping you organize your records chronologically.
Focus on Flow: It removes the cleaning columns to focus strictly on the water itself: “Cold Water Temp,” “Hot Water Temp,” and “Water Flush”.
Notes Section: A simple “Notes” column allows for recording observations like “Low pressure” or “Discolored water.”

Best for: Verified safety inspections.

This template adds a layer of accountability to your water safety program.

Verification: The key feature is the “Checked By” column. This requires the technician or supervisor to sign or initial every single entry, verifying that the check actually happened.

Context: It includes a specific “Details” column right after Location. This allows you to specify exactly which outlet is being tested (e.g., “Tap 3, Left Sink”).
Full Compliance: It tracks “Cleaning and Descaling” alongside the standard Temperature and Flush checks.
Clear Layout: The table is spacious, making it easy to write detailed findings during an inspection.

Best for: Standard monthly water flushing.

This is a straightforward log for landlords or managers who need to prove regular turnover of water in the system.

Standard Metrics: It tracks the core data points: “Date,” “Time,” “Location,” and specific columns for “Cold Water Temp” and “Hot Water Temp”.
Flush Confirmation: The “Water Flush” column is prominent, serving as a checklist for little-used outlets.
Footer Tracking: It features a “Month:” field at the bottom, making it easy to file in a compliance binder.
