Everything you need to know about the annual cooling tower information return (ITRE)

If you own a cooling tower (ITRE), don’t forget that you have certain obligations under Section VII: Provisions for the maintenance of a water-cooled cooling tower installation of the Building chapter of the Safety Code (CBCS).

  • Modifications to the network with an impact on water quality
  • A health threshold exceedance for Legionella pneumophila concentration, i.e. greater than 1,000,000 cfu/l
  • 5 years have passed

If you don’t meet any of the above criteria, your program needs to be revised!

Don’t worry, we can help!
