Cooling Tower Inspection Logger
ASHRAE 188-minded tower rounds — drift, biofilm, basin, fill, fans, treatment status and Legionella program items; offline + GPS.
New cooling tower inspection
Weekly visual rounds in season; monthly detailed checks; per your ASHRAE 188 water-management plan for sampling and cleaning cycles.
Field guide: Cooling Tower Inspection Logger
Cooling towers are the source in most large Legionnaires' outbreaks — warm water, biofilm and a machine engineered to aerosolize it — and the regulatory answer (ASHRAE 188, NYC's tower law, equivalents spreading) is a water-management plan with verifiable tasks. This logger is the field half of that plan: weekly eyes on the basin (biofilm and stagnant zones are the organism's home), the drift eliminators that keep aerosols inside, dosing systems actually feeding, and the program clock — samples, cleanings, idle-restart procedures.
Two findings escalate past maintenance: visible drift reaching air intakes or public areas (the exposure pathway in person-by-window outbreaks), and towers idle more than a few days without a layup/restart plan — restart of stagnant towers is a known outbreak trigger. 'Vibration switch bypassed' earns a flag because that's how fan assemblies leave towers at speed.
Field tips
- Touch-test surfaces in the splash zone with a gloved finger — slime you can feel is biofilm regardless of how clear the water looks.
- Stand downwind 10–20 m on a humid day: drift you can feel as droplets (not plume vapor) means eliminators need attention.
- Before any restart after idle periods, verify the WMP's flush/disinfect steps happened — log the dates, not assumptions.

Frequently asked questions
What does ASHRAE 188 actually require?+
A building water-management program: a team, water-system flow diagrams, identified control points (towers are always one), control limits, monitoring, corrective actions, and verification — documented. For towers that means defined dosing, residuals, cleaning cycles, and Legionella sampling cadence. This log evidences the monitoring and corrective-action layers.
Why are drift eliminators a health control?+
They strip droplets from discharge air — the difference between humid plume and aerosolized basin water carried downwind. Damaged or displaced eliminators show up repeatedly in outbreak investigations. Visible droplets beyond the unit, or mist wetting nearby surfaces, mean the control has failed and the finding is health-class, not mechanical.
What's the risk of an idle tower?+
Stagnation: biocide decays, temperatures sit in the growth band, biofilm flourishes — then restart aerosolizes the accumulation. Plans therefore specify layup (drain or maintain treatment) and pre-restart disinfection for idle periods (commonly >3–5 days). 'Idle without plan' is among the most predictive findings this log carries.
How do tower registration laws work?+
Jurisdictions like NYC require registration of towers, mandated WMPs, quarterly-or-better inspections, sampling, and reporting of exceedances — with public enforcement. Even outside such cities, ASHRAE 188 has become the standard of care cited in litigation; dated field logs are the inexpensive proof your program existed before the subpoena.
