Free Commercial Pool Log Book Template

Parker Conley December 2025 8 min read

Every commercial pool operator in the United States is required to maintain daily water quality records. Health departments mandate these logs as proof that your pool is safe for swimmers, though specific requirements vary by jurisdiction since states and counties voluntarily adopt portions of the CDC's Model Aquatic Health Code (MAHC) or set their own standards. Whether you manage a hotel pool, apartment complex, fitness center, or HOA community pool, proper record-keeping protects both your swimmers and your business.

What Health Departments Require

While specific requirements vary by state and county, health departments universally require commercial pools to record water quality tests at least twice daily: once before opening and once during peak usage or at closing. Many jurisdictions require hourly testing during operating hours.

What's Included in Our Log Book

Our free log book template includes:

• 31 daily log sheets - One full month of records
• Water chemistry tracking - Free chlorine, pH, combined chlorine, alkalinity, cyanuric acid

• Chemical addition log - Track what you add and when
• Maintenance checklist - Daily and weekly task tracking
• Incident log section - Document any issues or closures
• Facility info page - Pool volume, equipment specs, emergency contacts

Why Proper Record-Keeping Matters

Pool chemical log sheets serve as your facility's insurance policy. In the event of a waterborne illness complaint or injury claim, your logs are the only proof that proper water quality was maintained. Incomplete or inaccurate logs can result in:

• Health department citations - Fines ranging from $100 to $10,000+ depending on jurisdiction
• Pool closure orders - Forced shutdown until compliance is demonstrated
• Liability exposure - Difficulty defending against injury claims
• Insurance issues - Policy cancellation or claim denial

Tips for Consistent Record-Keeping

1. Test at the Same Times Daily

Establish a routine testing schedule and stick to it. Consistent timing makes it easier to spot trends and ensures you never miss a required test.

2. Use Proper Testing Equipment

Invest in quality test kits or a digital photometer. Replace reagents before they expire, and calibrate electronic testers regularly.

3. Record Immediately

Write down results as soon as you get them. Don't rely on memory - even a few hours later, details can become fuzzy.

4. Keep Logs Accessible

Store your log book in a waterproof location near the pool equipment. Health inspectors may ask to see it during unannounced visits.

5. Train All Staff

Every person who tests the water should understand how to properly record results. Inconsistent handwriting or abbreviations can cause confusion.
