Minimising the risk to the public of catching Legionnaires disease is a legal requirement. With over 50 years of experience, we help clients to comply with the Water Supply Regulations 1999, The Health and Safety at Work Act 1974 and the COSHH regulations 2002. 

The code places responsibility on employers and others to identify, assess, prevent and control the source of risk for Legionella bacteria. It is extremely important that all records of implemented precautions are kept and maintained.

We work alongside building managers, facilities managers, landlords and property agents to create bespoke maintenance schedules for your water hygiene systems. Our technical expertise, robust engineering experience and excellent customer care ensure your organisation meets the associated legal obligations.

The Health and Safety at Work Act (1974) Section 2 requires employees to ensure plant and equipment is safe and without risks, this means that there is a responsibility to ensure there is no risk of infection from the pool water, or from any other system on the premises.

Regular testing of pool and spa facilities is required to ensure the safety of swimmers visiting your premises. It also plays an important role in protecting the infrastructure of your pool. Effective water management enables the optimisim of your treatment plan, maintaining water balance and disinfection control.

Daily pool water testing is required to effectively monitor pH levels and disinfectant residuals such as chlorine and bromine, to prevent chemical irritation for swimmers. To maintain water quality, weekly tests must also be carried out to test parameters such as alkalinty, total dissolved solids, calcium hardness and water balance.

To eliminate the risk of recreational water illnesses, microbiological pool and spa tests must be done at least monthly. Microbiological testing is critical in stopping the spread of bacteria and viruses.

Hydraclean Ltd can offer the following services for your pool:

  • Full monthly chemistry testing of pool and spa water for pH, total dissolved solids, conductivity, total alkalinity, total hardness, calcium hardness, iron, chloride, free, total and combined chlorine, temperature and langelier index
