About Water Treatment

Manage and prevent Legionella with cooling system water treatments.

In the right environment, Legionella bacteria can disperse through water droplets, putting employees, customers, contractors and visitors at risk of being contaminated and exposed.

Aqua provides cooling system water treatment services to prevent contamination and keep your company safe. Contact us now to arrange your visit or treatment.

One-Off & Regular Water Treatments

Aqua provide a range of clearing, disinfectant, cooling system water monitoring and treatment as either a stand-alone service or an integral part of one of our Planned Preventative Maintenance plans, so you can rest assured that your people and operation are always protected.

Our specially formulated range of AquaCool cooling system water treatment products has been created to effectively cleanse and protect cooling systems from legionella bacteria, limescale, iron and debris build-up. Our services include:

Stay Compliant With Cooling System Water Treatments

Legionnaire’s disease is a potentially fatal infection. The disease is caught by the inhalation of water droplets from water systems containing the organism at high levels. Although legionnaires disease is relatively rare, other infections can also occur, such as Pontiac Fever and Lochgoilhead Fever.

There is a greater risk of legionella bacteria developing if water is stored or re-circulated as part of your cooling system, the water temperature in all or some part of the system is between 20–45 °C and there are deposits that can support bacterial growth, such as rust, sludge, scale and organic matter.

The true numbers of legionella infections are not known, but the detected outbreaks attract massive publicity and could cause system operators to be prosecuted for serious offences.

asked questions

The inspection and treatment protocol for cooling towers is set out in legislation to ensure the equipment is safe and legionella free. By their very nature, cooling towers evaporate water on a regular basis. The evaporation process itself also leaves residual salts behind which means bleeding additional water to eliminate salt build up. When this water is replaced, it needs to be correctly treated and the process is ongoing. Mandatory inspections will be the same for a 500kW tower as for a 50MW installation, so costs can really impact if you have a smaller tower. For some customers cooling towers are the best solution, however we can offer alternatives such as adiabatic units – our sales team will happily talk you through the benefits of each.

The HSE publishes an Approved Code of Practice (ACoP L8), which provides guidance on legionella control and legionella testing. Complying with L8 helps you to comply with the law and avoid significant fines or even a custodial sentence.

Cooling towers, evaporative condensers, adiabatic coolers and any other equipment linked to, or with, a stored or re-circulating water source are considered high risk breeding grounds for the legionella bacteria.

At Aqua, we can provide you with a comprehensive legionella management strategy to help ensure your statutory compliance to ACoP L8 and reduce your risk of a legionella outbreak.
