According to a survey conducted by Goodway Technologies, 88 percent of respondents indicated that Legionella prevention was very important or extremely important from management’s perspective. More than half of survey respondents, meanwhile, acknowledged the potential risk of Legionella from cooling towers comes up in conversation with leadership at least every few months.

With that in mind, here are some proper steps for cooling tower maintenance.

  • Inspect cooling towers at least monthly.
  • Clean cooling tower basin surfaces.
  • Clean the cooling tower fill.

ASHRAE Standard 188-2015 established minimum risk-management requirements for building water systems. These specifications provide guidance on logging, maintaining and cleaning cooling towers to mitigate Legionella breakouts.
