Water Hygiene Compliance

Herts Enviro Services offer a comprehensive water hygiene service to comply with ACoP L8/HSG 274 pt.2 legionella control. This includes, but is not limited to:

• Risk Assessment: Conduct a thorough risk assessment of water systems to identify potential sources of Legionella growth and transmission. This includes assessing the design, operation, and maintenance of the systems, as well as considering factors such as water temperature, stagnation, and the presence of biofilms.
• Written Control Scheme: Develop and implement a written control scheme based on the findings of the risk assessment. The control scheme should outline specific measures and procedures to control and prevent the proliferation of Legionella bacteria. It should include details on monitoring, maintenance, cleaning, disinfection, and any necessary corrective actions.
• Appointing a Responsible Person: Designate a competent person or persons to be responsible for overseeing the implementation of the Legionella control measures. This individual should have the necessary knowledge, skills, and authority to ensure compliance with the control scheme.
• Training and Competence: Ensure that personnel involved in the operation, maintenance, and monitoring of water systems receive appropriate training and instruction on Legionella awareness, risk management, and control measures. This includes training on the proper use of equipment, sampling techniques, and record-keeping procedures.
• Monitoring and Inspection: Establish a regular monitoring and inspection program to assess the effectiveness of control measures and identify any potential issues or deviations from the control scheme. This may involve monitoring water temperatures, conducting microbiological sampling, inspecting equipment and systems, and assessing the condition of water storage tanks and distribution networks.
• Water Treatment and Maintenance: Implement appropriate water treatment measures to control Legionella growth, such as maintaining water temperatures outside the optimal range for bacterial proliferation, periodic cleaning and disinfection of water systems, and the use of biocides or other chemical treatments where necessary. Regular maintenance of equipment and systems is also essential to prevent conditions conducive to Legionella growth, such as leaks, corrosion, and scale buildup.
• Record Keeping: Maintain detailed records of all activities related to Legionella control, including risk assessments, monitoring data, inspection reports, maintenance schedules, cleaning and disinfection procedures, and any corrective actions taken. These records serve as evidence of compliance with regulatory requirements and provide valuable documentation for audits and inspections.
• Review and Revision: Regularly review and, if necessary, revise the Legionella control measures based on monitoring data, changes in water systems or usage patterns, regulatory updates, and any incidents or outbreaks of Legionnaires’ disease. Continuous improvement is essential to ensure the effectiveness of the control regime in minimizing the risk of Legionella contamination.

Sidestream Filtration

Herts Enviro Services Limited has tried and tested water treatment techniques, products and equipment in order to increase efficiency, reduce energy waste and improve longevity of existing heating systems. This method of cleaning not only achieves these aims at the conclusion of the project but also restricts waste of valuable water resource by restricting the amount of flushing water required.

The SSF Units are generally used in conjunction with limited amounts of flushing when required. This being necessary to move large amounts of debris prior to chemical use and to finally flush remnants of chemical cleaners and other soluble contaminants.

There are many beneficial aspects of using this method of remediating a heating system back to a clean and efficient operational condition and one of the most significance is of the restricted use of water resource.

Side Stream Filtration will also allow the ongoing use of the system during the cleaning process and will capture debris from all zones of a system, including variable temperature circuits, as it cycles through its various stages of normal operation.

However, as with every form of system cleaning, the method should be correctly specified and applied and no single method provide a panacea for successful cleaning.

For this reason our team treat every enquiry as a bespoke project and ensure that through technical discussion and gathering of site information that the client is always satisfied that end results satisfies the expectation and constitutes a successful result.
