Cooling tower water treatment and legionella sampling

Chemistry converts; microbiology does not. Let the controller run the chemistry and log it, and keep the sampling calendar because the lab certificate is the compliance record.

the interval is set by law or a statutory code and stays on the calendar
Online water treatment controller for chemistry; laboratory analysis for microbiology

asset class
Condition that replaces the interval
Partly. Conductivity, pH, biocide residual and blowdown can be controlled and logged continuously; microbiological sampling stays on its interval because a lab result is the evidence the regulator wants.
Reading that proves it
Conductivity, pH, oxidising biocide residual, dip slide or TVC result, legionella sample result
Why the interval stays
Cooling tower registration and periodic legionella sampling are required under state public health regulations in Australia and under HSG274 (COSHH) in the UK; monthly sampling is the usual minimum.
Evidence an auditor accepts
Water treatment log with the daily chemistry and the monthly laboratory results per tower
First move
Log the controller readings into the same register as the lab results so an inspector sees the chemistry that preceded each sample.
