Standards for Chlorination and Water Quality

Honolulu pool water quality requirements implement state public-health standards and local operational rules for pools and spas. Typical requirements include maintaining free chlorine or combined chlorine within set ranges, pH control, filtration performance, and continuous monitoring and recordkeeping. For Honolulu Parks public pools, follow operational guidance from the City department responsible for public pools and the State Department of Health for sanitary standards and inspection criteria.

Maintain pH and free chlorine within recommended ranges and log readings daily.

Testing Frequency & Methods

Testing frequency and methods vary by use (public municipal pools, commercial pools, hotel pools, residential common-pool facilities). Operators should maintain written test logs, use approved test kits or laboratory confirmation for certain parameters, and retain records for inspection.

  • Daily testing for free chlorine and pH is commonly required; specific intervals are determined by the enforcing rule or permit.
  • Recordkeeping: retain daily logs on-site and produce them to inspectors on request; retention periods are set by the applicable regulation or guidance.
  • Use approved reagents or electronic analysers; calibration and maintenance records should be available.
