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:
- Manual dosage of disinfectants, dispersants and bio dispersants
- Introduction of continuous automated chemical dosing equipment
- More frequent microbial monitoring (e.g. monthly legionella sampling), and;
- partial system shutdowns (e.g. single cooling tower cells) to allow inspection and cleaning of that part of the system
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.

Frequently
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.

Frequently Asked Questions
Why is water treatment important for cooling systems?
Untreated water in cooling systems leads to scale build-up, corrosion, and biological growth including legionella. These issues reduce efficiency, shorten equipment life, and in the case of legionella present a serious health risk. Regular water treatment protects both your equipment and your people.
What types of cooling system does Aqua provide water treatment for?
Aqua provides water treatment services for a range of temperature control equipment. Call the team for detailed information for your exact set up.
How often should cooling tower water be tested and treated?
Cooling tower water should be tested regularly often weekly or fortnightly depending on the system and the season. This is partly a legal requirement under L8 legislation to manage the risk of legionella. Aqua can set up a routine inspection and treatment schedule for your site.
What is included in Aqua's water treatment service?
Aqua’s water treatment service includes water sampling and analysis chemical dosing legionella risk assessment and control programme implementation and written service records. We ensure your system remains compliant with ACOP L8 guidance.
Can Aqua carry out a one-off water treatment visit or does it have to be a contract?
Both options are available. We can carry out a one-off water analysis and treatment visit or set up an ongoing contract if you prefer the peace of mind of regular scheduled visits. Our team will advise on what is appropriate for your system and its risk level.
Water Treatment Cleans Up For Plastic Manufacturer
Poor water quality was hindering production for a plastic manufacturer based in Kent. Aqua delivered a water treatment programme to resolve long-standing issues and to safeguard future production.
As a result of the work, the client has a very clean water system which requires no manual intervention. It has restored reliability to their production schedule and will bring additional cost savings from them not having to unblock and replace their tools. The design of the filter also prevents water loss, something that is common if a standard back washing style filter is used.
