Cooling Tower Water Treatment Best Practices

Cooling tower water treatment is closely regulated by New York City laws. Strict maintenance and treatment requirements were implemented after a fatal outbreak of Legionnaire’s Disease in 2015, and with the steadily rising incidences of Legionnaire’s cases since then, inspectors are out in full force.

While cooling tower problems may arise from corrosion, scaling or fouling, all of which are prevented by proper cooling tower water treatment, the biggest threat to your business is the threat of a legionella outbreak. Legionella can also be controlled through proper cooling tower water treatment.

Preventing Legionella Growth in NYC Cooling Towers with Cooling Tower Water Treatment

Local Law 77 and Chapter 8 to Title 24 of the Rules of the City of New York outline the maintenance and inspection requirements, including water treatment, for all cooling towers in NYC. Following these regulations exactly will protect your business from the steep costs of non-compliance.

NYC requires all cooling towers to receive routine inspections and legionella testing by a qualified professional every 90 days. On top of this, cooling towers must be disinfected twice a year by a licensed pesticide applicator, regardless of whether there’s legionella or not. All cooling towers are also subject to random inspections – you can be sure this will happen to your cooling tower as Legionnaire’s Disease cases have been on the rise, despite cooling tower regulations.

Cooling Tower Audits for Water Treatment Compliance

One of the best ways to protect your business from non-compliance, which can lead to huge fines, is to hire a certified, independent third party to conduct cooling tower audits. These audits can help ensure everything is being done correctly to minimize the risk of legionella growth in your cooling tower.

With the uptick in inspections to combat legionella growth, a lot of cooling towers are failing inspections because of improper documentation. Every maintenance and inspection item performed on a cooling tower must be documented immediately. If maintenance isn’t documented properly, you will be fined as if you hadn’t performed it at all. Cooling tower audits can ensure all documentation is in order, too. That way, your business is better protected from costly fines.

Cooling tower water treatment is closely regulated by New York City. Implementing best practices includes understanding and closely following all cooling tower regulations, but also requesting cooling tower audits to ensure you’re in compliance and there’s no legionella growth in your cooling towers.

While scaling, corrosion or fouling can cause problems for cooling towers, there’s no greater threat to your business than legionella growth. Fines for non-compliance are high and remaining in compliance is not an easy task for anyone.

A certified, independent third party is best positioned to provide an unbiased cooling tower audit.
