Regular maintenance of your building’s water system to remove the scale and biofilms that harbor legionella is the foundation of preventing the growth and spread of illness and associated publicity from seriously impacting your facility. Available legionella prevention solutions such as ultra-violet and ozone only address new water coming into a building water system, not what is already there. Chlorine dioxide and copper-silver are commonly used to treat the water, but they cannot remove the scale or biofilms in your pipes. Hyperchlorination is not effective long-term. Super heating consumes enormous energy if done right, and then only addresses a part of the problem. Legionella is an “all water” problem and it lives in the pipes, showers, faucets and water fountains throughout your building. The question is only what will make it bloom. Prevention with Clearitas Clearitas® is used in all water systems to remove biofilms and scale – the places where legionella can establish itself and find protection from disinfectants and remediation tactics. Continuous use actively inhibits future legionella growth and prevents occurrences by removing the environment that harbors legionella and other waterborne pathogens. Vital to any facilities’ legionella risk management plan, Clearitas reduces the likelihood that every end-point of use – faucets, showerheads, drains, water fountains, etc. – dispenses clean, safe water. Clearitas is a safer and more cost-effective alternative to other methods of legionella water treatment and has very little capital investment. This nonhazardous, low maintenance solution is NSF 60 certified and safe for use in all water systems, including drinking water so it can be used without concern for your occupants or guests. of using Clearitas for legionella prevention include:
Assemble a team of infection control personnel, facilities management, engineers and state-certified water operator. Consult an HACCP-trained professional.
Identify the end-point uses of potable and utility (non-potable) water systems within the building. Create a process flow diagram of both systems.
Analyze the risk at each point in the process / identify the critical control points (CCP).
Determine the type of hazard control method / water treatment if the critical control limit is exceeded.
Establish monitoring procedures including frequency of monitoring.
