Water Hygiene Services

Chlorine dioxide has been shown to be extremely effective in the control of legionella bacteria in water systems and the prevention of Legionnaires’ disease, as it has been shown to be especially effective at penetrating and killing biofilms and the Legionella bacteria that they harbour.

Chlorine dioxide generators are an efficient way to generate a powerful disinfection agent for use in a wide range of water treatment applications.

Chlorine dioxide is produced by the controlled mixing of hydrochloric acid and sodium chlorite. Traditionally, most types of chlorine dioxide generators use chemical dosing pumps to transfer the calculated amount of hydrochloric acid and sodium chlorite to a reaction/mixing chamber where the solution is stored ready for dosing.

Hydraclean can offer the below services:

• Tank or mains fed disinfections of hot & cold water services using chlorine dioxide
• Installation of automatic chlorine dioxide generators
• Service of chlorine dioxide generators
• Monthly chlorine dioxide tests to generator and outlets to ensure the whole system is at correct control levels

BS 8558 specifies that hot and cold water systems should be cleaned, flushed and disinfected if:

Domestic water sample results indicate contamination of the water system,

Routine inspection of the water storage tanks evidences contamination or stagnation,

If you are an employer, or someone in control of premises, including landlords, you must understand the health risks associated with Legionella. Risk assessments are compulsory for most public and commercial buildings in the UK and therefore must be carried out thoroughly. They provide you with the evidence that bacterial growth is minimal and that the water you are providing is clean and safe.

The Health and Safety Executive (HSE) recommends choosing a contractor who you are confident will do the work required to the right standard. As a trusted legionella compliance partner for over 30 years, Hydraclean has the experience, expertise and qualifications to support you.

All our Legionella Risk Assessments are carried out in accordance with L8 and BS 8580-1:2019 and are tailored to include:

• A scored & banded risk assessment
• A schematic interpretation of the systems
• Review of management procedures
• Statement of control
• Preparation of a scheme to control the risk
• Recommendations for remedial actions
• Photographic Evidence

 

Although the risk of Legionnaires disease being spread through large-scale water systems cannot be eliminated, the risk associated with the disease can be greatly reduced with a detailed and systematic maintenance schedule. Hydraclean can help you to implement, manage and monitor your water systems ensuring full compliance with all regulatory requirements.
