Effective water disinfection is essential for ensuring safe and compliant water systems. The goal of water disinfection of public water supplies is the elimination of pathogens responsible for waterborne diseases, which is a key aspect of regulatory compliance. Water disinfection is considered one of the most significant public health advances of the 20th century. The disinfection process is carried out in two key stages:
Both methods are crucial to safeguarding public health and ensuring continuous protection against waterborne pathogens such as Legionella. Regular monitoring of water systems is essential to ensure compliance with health regulations and to prevent contamination that could lead to waterborne illnesses.
Marlowe Environmental Services provides industry-leading water disinfecting solutions tailored to your site’s specific requirements. A multi-barrier approach employing multiple disinfection technologies is recommended for effective disinfection, as no single method is effective against all waterborne pathogens.
Primary water disinfecting is the first step in eliminating harmful microorganisms from water sources, ensuring it is safe for use. Marlowe Environmental Services utilises several advanced techniques, including chlorination, which effectively neutralises bacteria and viruses, and ultraviolet (UV) disinfection, a chemical-free method that disrupts microbial DNA to prevent reproduction. Ozonation is another powerful technique, using ozone gas to oxidise and destroy contaminants.
Each method has its advantages, and the right choice depends on factors such as water quality, industry requirements, and regulatory standards. Marlowe Environmental Services’ experts assess your needs to implement the most effective primary disinfection strategy for your site.
Secondary water disinfecting ensures ongoing protection by maintaining residual disinfection, specifically, an adequate free chlorine residual, throughout the water distribution system, ensuring microbial safety up to the consumer’s tap. This ongoing residual disinfection is critical for preventing bacterial regrowth, especially in pipe work, storage tanks, and cold water systems, and is a key factor in regulatory compliance and water hygiene.
Common legionella disinfection methods include low-level chlorination, which provides a measurable free chlorine residual for continued protection, and chlorine dioxide, valued for its stability and effectiveness against biofilm and biological fouling.
Silver-stabilised hydrogen peroxide and monochloramine are also used in engineered water systems for long-lasting microbial control, particularly where stagnant water or dead-end pipe work increases risk. Regular inspection and disinfection of storage tanks, pipe work, and both hot and cold water systems are essential to control legionella, prevent the formation of biofilms, and mitigate the increased risk of contamination from stagnant water.
Legionella risk assessment is fundamental in determining the appropriate legionella disinfection frequency and method, with at least twice-yearly disinfection often recommended, and more frequent interventions as indicated by water quality results or inspection findings. Legionella specialists play a vital role in implementing tailored legionella disinfection methods, including both thermal and chemical disinfection, to control legionella, ensure water hygiene, and protect against Legionnaires’ disease.
