Cooling Tower News Updates

100s Of Cooling Towers Examined After Melbourne Legionnaire’s Disease Outbreak In March That Had Six Confirmed Cases

Cleaning of large amounts of cooling towers in Melbourne Australia were undertaken after Victoria’s Department of Health and Human Services confirmed the outbreak in the Central Business District.

Just a few months ago there was discussion about many of Melbourne’s new apartment buildings posing a legionella bacteria risk due to their energy-efficient “warm water” systems.

$42 Million Cooling Tower Replacement At Nuclear Plant Being Proposed For Closure

Palisades Nuclear Power Plant, which according to WBFO has divided some residents in the area of Van Buren County in Michigan over its proposed closure, is replacing a cooling tower over the next 3-4 months. While the plant may be closing down, maintenance and upkeep will continue to be an ongoing job for quite some time.

Decommissioning and cleaning up a nuclear plant can take over 50 years. The Michigan Public Services Commission will host several public meetings in May before deciding on the final outcome of the plant. Economic impacts may be hard on some of the surrounding communities as the plant employs over 130 people.

Is Your Cooling Tower as Safe as You Think? Is Stricter Oversight the Answer?

Legionnaire’s Disease

Legionella bacteria, the source of Legionnaire’s Disease, has been repeatedly found in inspections of cooling towers after outbreaks. Many areas are turning to tighter rules and more vigorous inspections of cooling towers as a way to prevent outbreaks.
Public officials and building owners are being held to answer for the outbreaks, with various systems being looked at to help provide answers.

Accountability

According to an AP report on March 13th, an ex-Flint Michigan Official was given probation for neglecting to report a Legionnaire’s outbreak that occurred during the much publicized water scandal there last year.

Some areas have stepped up inspections, while others have added fines and new rules. Some areas have also stepped up educational resources and outreach to help those who manage facilities become more acutely aware of the needed precautions and maintenance procedures needed.

Seeking Answers

Operating procedures, maintenance, and cleaning are critical in preventing growth of the bacteria that cause Legionnaire’s disease. Due to changes in technology over time, many older buildings can also benefit from newer systems.

Educational outreach directly to owner of buildings is a benefit of cooling tower registration systems being tried in some jurisdictions. Such information can be critical in supporting owners, who are ultimately responsible for the maintenance their buildings.

The Centers for Disease Control and Prevention reports that “…about 5,000 cases of Legionnaires’ disease are now reported each year in the United States.” Luckily there is some good news on the recovery side. Legionnaires’ disease is most often non-fatal today, thanks to better detection and treatment of the disease.

In an article at the Charleston Gazette-Mail, Janet Briscoe at Kanawha-Charleston Health Department stated “People are getting treated sooner. It’s identified sooner, so the rates of death are a lot less than what they were in the past.”

Newer technology, better education and closer oversight of cooling towers are all coming together to prevent illnesses due to Legionnaire’s Disease.
