Cooling tower monthly service and sampling log

When you need this form

Cooling towers on hospitals, shopping centres, hotels and office towers get serviced and sampled on a monthly cycle. Water treatment is checked, the tower is inspected, and samples go off for Legionella and heterotrophic colony counts. Most states hold building owners to a documented monthly regime, and a result above the action level triggers notification and remedial work within tight timeframes.

This is a record health inspectors actually come and read. Gaps in the monthly sequence are the finding. Logged on the phone at the tower, each service carries its date, the technician, the readings and photos of the basin and drift eliminators, so the twelve month history is complete and continuous rather than reconstructed before an inspection.

What good looks like

• Tower identified by system number, matching the register and site plan.
• Water treatment readings recorded: biocide, pH, conductivity, dose rates.
• Sample details captured: date, point, laboratory, and result when returned.
• Exceedances flagged with the notification made and remedial action taken.
• Photos of basin, fill, drift eliminators, plus technician sign-off.
