Cooling Tower Legionella Inspection Checklist
Use this cooling tower legionella inspection checklist to inspect basin cleanliness, fill condition, fan and drift eliminators and biocide and water chemistry on energy & utilities sites so teams can confirm cooling towers remain hygienic, structurally sound, and thermally effective, recording pass, fail, or N/A and capturing a photo on anything that needs proof. Watch for biofilm in the basin, damaged fill and imbalanced fan. Records support L8 ACoP, HSG274 and ASHRAE 188.

Frequently Asked Questions
How is a scheduled cooling tower legionella inspection different from a general inspection?
It is scoped to the scheduled cadence and controls that facilities managers, water hygiene technicians, compliance officers run, not a one-off handover walk. It prompts basin cleanliness, fill condition, fan and drift eliminators and biocide and water chemistry, watching for biofilm in the basin, damaged fill and imbalanced fan, records pass, fail, or N/A with basin photo, chemistry log and fan amperage on critical items, and raises corrective actions with owners before sign-off. Run in InspectWrk, the record is timestamped and rolls into trend reports so repeat failures surface before the next audit.
What do facilities managers, water hygiene technicians, compliance officers check on it?
They work through each checkpoint to confirm cooling towers remain hygienic, structurally sound, and thermally effective, confirm the required controls are in place, and capture basin photo, chemistry log and fan amperage on anything that fails or needs proof. Priority failure modes include biofilm in the basin, damaged fill and imbalanced fan. Each checkpoint takes pass, fail, or N/A, and a failed item stays open until the fix is verified.
What evidence does it require?
It expects basin photo, chemistry log and fan amperage on failed or critical items, so findings rest on proof rather than memory. Records support L8 ACoP, HSG274 and ASHRAE 188, and every photo, note, and sign-off stays attached to the inspection instead of living in chat threads.
What does the cooling tower legionella inspection checklist check?
It checks basin cleanliness, fill condition, fan and drift eliminators and biocide and water chemistry across energy & utilities sites. The round exists to confirm cooling towers remain hygienic, structurally sound, and thermally effective. It prioritises failure modes such as biofilm in the basin, damaged fill and imbalanced fan. Facilities managers record pass, fail, or N/A on each item, capture photo evidence on anything that needs proof, and assign corrective actions with owners and due dates. Evidence expectations include basin photo, chemistry log and fan amperage. A failed item stays open until the fix is verified, and it runs offline so a weak signal never costs a round. Run in InspectWrk, every finding is timestamped and exports as a single energy & utilities report aligned to L8 ACoP, HSG274 and ASHRAE 188.
What is a cooling tower legionella inspection checklist?
Quick Answer
A cooling tower legionella inspection checklist is the structured inspection used to confirm cooling towers remain hygienic, structurally sound, and thermally effective that energy & utilities teams use to check the key inspection points, assign owners to any failures, and close them with photo proof. Completed in InspectWrk, it is timestamped, works offline, and exports as an audit-ready energy & utilities report for L8 ACoP, HSG274 and ASHRAE 188.
A cooling tower legionella inspection checklist is the structured inspection used to confirm cooling towers remain hygienic, structurally sound, and thermally effective that energy & utilities teams use to check basin cleanliness, fill condition, fan and drift eliminators and biocide and water chemistry, capture photo evidence, and track corrective actions to closure. Its job is to confirm cooling towers remain hygienic, structurally sound, and thermally effective. It replaces the paper cooling tower legionella inspection checklist tick sheet and the WhatsApp photo with one inspection record per scheduled round, attributed to the inspector and the site. Inspectors specifically watch for biofilm in the basin, damaged fill and imbalanced fan. Field language covers drift eliminator, cycles of concentration and legionella control.
Why are cooling tower legionella inspections still chased on WhatsApp?
HVAC and water hygiene technicians still miss biofilm in the basin, damaged fill and imbalanced fan when rounds are ticked without basin photo, chemistry log and fan amperage.
Without a single inspection record, teams reconstruct the evidence from phones instead of proving L8 ACoP, HSG274 and ASHRAE 188 readiness.
Before and After InspectWrk
Before InspectWrk
- energy & utilities inspections for cooling tower legionella happen on paper or in WhatsApp threads, with no timestamp and no photo evidence.
- Legionella checks are recorded on paper that never reaches the responsible person before the audit.
- You find out about a cooling tower legionella issue from a client complaint or an auditor, not from your own team in real time.
After InspectWrk
- Facilities managers complete the inspection in the app with photo evidence at the cooling tower legionella, even offline.
- Managers see open findings, closure status, and L8 ACoP, HSG274 and ASHRAE 188 evidence live on one dashboard.
- Overdue corrective actions escalate automatically so the fix happens before the next energy & utilities audit.
Why is a cooling tower legionella inspection checklist important?
It helps facilities managers and supervisors keep energy & utilities work consistent, safe, and auditable, with the evidence needed for L8 ACoP, HSG274 and ASHRAE 188:
- Cover the full inspection:structured checks across basin cleanliness, fill condition, fan and drift eliminators and biocide and water chemistry surface biofilm in the basin, damaged fill and imbalanced fan before they reach handover, audit, or the next shift.
- Document energy & utilities findings with the right proof:capture basin photo, chemistry log and fan amperage on every issue so nothing rests on memory.
- Stop repeat energy & utilities findings:assign the fix, set a deadline, and escalate overdue actions before the next round comes around.
- Stay audit-ready:keep one timestamped record for L8 ACoP, HSG274 and ASHRAE 188 you can export instead of rebuilding it from scattered photos and spreadsheets.
What should be included in a cooling tower legionella inspection checklist?
A complete cooling tower legionella inspection checklist works through basin cleanliness, fill condition, fan and drift eliminators and biocide and water chemistry, then records inspection context, scored checkpoints, and evidence with corrective actions:
Inspection context
Record where and when the inspection runs:
- Site, energy & utilities location, and asset identification
- Inspector, date, and the energy & utilities areas or assets in scope
- Reference numbers or schedules linked to the checklist
Checkpoints and scoring
Define what each checkpoint verifies and how results are scored:
- basin cleanliness
- fill condition
- fan and drift eliminators
- biocide and water chemistry
- structural corrosion
- Failure watchouts:biofilm in the basin, damaged fill and imbalanced fan
- Evidence:basin photo, chemistry log and fan amperage
- 20 fields aligned to the checklist
Evidence and corrective actions
Make every finding traceable and actionable:
- Capture basin photo, chemistry log and fan amperage on failed or critical items
- Corrective actions with owners and due dates for energy & utilities teams
- Sign-off, completion status, and follow-up notes
How do teams use a cooling tower legionella inspection checklist?
Follow these steps to run the cooling tower legionella inspection checklist:
- Fill in the cooling tower legionella header: inspector, site, date, and areas in scope.
- Work through basin cleanliness, fill condition, fan and drift eliminators and biocide and water chemistry in order, recording pass, fail, or N/A.
- Attach basin photo, chemistry log and fan amperage wherever a failure or observation needs proof.
- Raise actions for biofilm in the basin, damaged fill and imbalanced fan with owners and deadlines before sign-off.
- Review the cooling tower legionella summary, share the report, and keep the record for your audit trail.
