The cleaning, disinfection, and chlorination of water systems are critical to maintaining suitable water hygiene standards. This is particularly so in domestic water systems where microbial contamination can lead to profound health implications. That's why regular water system chlorinations are very important.
Chlorination Activities
Cleaning and chlorination activities involve adding chlorine, a cost-efficient but effective disinfectant, to a mains water supply. The chlorine is added at a specific concentration and for a specified period to clean and disinfect the water system, pipework, and water tanks.
Why do we need to Chlorinate Water Systems?
Chlorinating a water system is a proven way of disinfecting water systems and their constituent parts. In addition, it helps to remove dangerous waterborne pathogens, including Pseudomonas and Legionella bacteria. These bacteria can quickly build up over time and contaminate the entire water system.
Disinfection Process
Water system chlorination using chlorine has been used to clean and disinfect water systems successfully in the UK for many years. New water systems have a legal requirement to have a mains chlorination performed and subsequent certificate issued. This is an essential part of the disinfection process identified in several key standards, including BS EN 806-5:2012, BS8558:2011, and BS PD 855468:2015. These British Standards deal with the design, installation, testing, operation, cleaning, disinfection, and maintenance of drinking water services inside buildings.
When is Water Chlorination Required?
Chlorination of water systems, either new or existing, should be carried out for the following reasons:
- Contamination or possible contamination of water systems
- Legionella risk assessment results recommend cleaning and chlorination.
- Water system inactivity and stagnation
It is a legal requirement for new, refurbished & modified water systems to have a mains chlorination and subsequent chlorination certificate issued before the pipe is connected to a mains water system. In addition, water utility companies impose strict standards for the cleaning and disinfection of mains water systems before connecting to their network.
