Legionella in Swimming Pools | Expert Treatment Options from AMES Group

Maintaining your swimming pool or spa is an essential practice in order to ensure user safety. Understanding water chemistry is important because while your water may look crystal clear, it does not necessarily mean it’s healthy.

AMES Group provides comprehensive Legionella assessments for all types of swimming pools across Birmingham and the UK. We also provide a range of swimming pool treatments alongside our Legionella treatment.

We Treat the Following for Legionella:

The nature of public swimming facilities means the prevention of pool contaminants reaching the water is impossible. Therefore, appropriate water treatment helps to protect customers from the transmission of infectious disease. Of course, it also helps to ensure that water is kept clean, clear and as pleasant as possible for guests and members.

We also provide treatment for:

  • Chlorine swimming pools
  • Saltwater pools
  • Hot tubs
  • Public and leisure pools

Legionella Risk Assessments for Spa Pools

spa risk legionella The most common water systems we treat are spa pools (or hot tubs, portable spas etc). These water systems pose a greater risk of Legionella developing as they have the ability to provide a perfect breeding ground for the bacteria (Legionella pneumophila).

We provide a service that assesses the quality of your water, monitors the temperature control and ensures your water systems are operating at the correct temperatures and guidelines.

How do spa pools present a risk of Legionella?

Hot tubs and spa pools that are not regularly cleaned are at a higher risk of Legionella bacteria forming. This, combined with incorrect temperature settings and monitoring will greatly increase the risk of Legionella presence which can lead to Legionnaires disease.

To reduce this risk, you must:

  • Regularly monitor temperature settings and ensure no water systems are left to stagnate (this is a perfect breeding ground for Legionella)
  • Ensure pipework is clean and the materials are not able to harbour microbial growth
  • Water should be analysed regularly to ensure the treatment programme is working

Our technicians provide comprehensive risk assessments for both domestic and commercial hot tubs and spas. Alleviate the stress and concern by contacting our team today.

Types of swimming pool water treatment

There are a number of different types of swimming pools to consider regarding treatment. All swimming pools differ in the way they operate, for example, a hot water pool (like a Jacuzzi) is built and performs different to a recreational swimming pool. Some use water recirculation systems and other pools utilise constant water refreshment.

Some of the other main differences are:

  • Size
  • Water temperature
  • Cleaning systems
  • Type of water (salt or chlorine)
  • Disinfection system used

The most common pool systems are recirculation and refreshment systems. In water circulation systems, the water is recycled and funneled back into the pool via a purification system. This type of system is commonly used in public swimming pools and water parks due to its cost-effectiveness.

Water refreshment pools do not recycle the water. Instead, the pool is fed a constant stream of fresh water and the old water is discharged either into a purification plant or the sewer.


Legionella Treatment for Leisure Swimming Pools

Leisure facilities which have swimming pools or spas require consistent water treatment to ensure that the pool water is free from viruses, harmful substances, bacteria and pathogenic contaminants and the threat of Legionella.

Organisations considering the construction of a swimming pool at their facilities have to consider a number of public health implications before planning and construction begins.


Purifying Swimming Pool Water

All swimming pools must undergo treatment to ensure no harmful chemicals are circulating the pool.

In addition to testing and chemically treating swimming pool water we can also arrange regular water purification services. Swimming pool purification can be separated into four steps, transportation, purification, removal of harmful substances and the final addition of a flocculant.

Transportation – the water is transported from swimming pools to a purification plant, where it is then funneled through a hair removal filter. This filter catches and eliminates any row pollutions, such as hair, plasters, leaves and anything else that may have found its way into the system. The flocculant is added to merge colloids together; colloids are visible particles that can cause harm and spread bacteria in the pool.

Examples include:

  • Skin tissue and saliva
  • Textile fibers
  • Soaps
  • Skin fats
  • Cosmetic products

These particles are merged, caught and discarded appropriately. Sand filters are also used to remove suspended particles. Pollutants get discharged into the sewage system.

Without the use of a flocculant, it would begin to cause turbidity in the water. Turbidity is when the water loses its transparency, and it can vary depending on the amount of particles found within the water. Turbidity is a good way to assess water quality.


What Swimming Pool Treatment Do I Need?

The type of treatment required may vary depending on the nature of the pool. For example, chlorine pools that make use of a recirculation system (which involves the pumping of water through a filter before being returned to the pool) will differ to pools that use constant water refreshment.

Speaking to one of our health and safety executives will help you understand what treatment is best suited for your pool.

Control the Risk of Legionella – Contact AMES Today

AMES Group are able to treat every type of swimming pool for Legionella and other water treatments. We provide regular water monitoring or sampling checks to ensure the safe and appropriate dosing takes place. Pumps, tanks and bunds can be supplied as required.

The chemical treatment of swimming pool and hot tub/spa water includes our personnel using chemical dosing equipment on site, the correcting of PH levels through acid dosing and the provision and use of cleaning chemicals such as chlorine.
