Cooling Tower Inspection and Maintenance
Microorganisms including Legionella bacteria can exist in premise
plumbing including cooling towers. The development of an effective
water management plan (WMP) and implementation of maintenance
procedures are essential to prevent the presence, dissemination and
amplification of Legionella bacteria and other waterborne contami-
nants throughout premise plumbing. Before operating the cooling
tower, the water management plan and maintenance procedures
must be in place and regularly practiced.
In addition, the following steps are recommended:
Do NOT attempt any service unless the fan motor is locked out.
• Consult a knowledgeable water treatment professional to clean and treat
your cooling tower. See
Tower Startup
section of this manual.
• Cooling towers must be cleaned and disinfected regularly in accordance
with local public health services and recommendations. • Workers perform-
ing decontamination procedures must wear personal protective equipment
(PPE) as directed by their facility safety officer.
• Cooling towers must be visually inspected regularly to assess signs of
bacterial growth, appearance of debris and scale on drift eliminators and
general operating conditions.
• Replace worn or damaged components.
To minimize the presence of waterborne microorganisms, including Legionella,
follow the water management plan for your facility, perform regularly scheduled
cooling tower inspections and maintenance, and enlist the services of water
treatment professionals.
