Following the chlorination process, it is required that the water supply pipework is tested before a connection is made to the mains water. This is essential to ensure suitability and safety for the provision of drinking water.
Water Chlorination is the process of adding chlorine or chlorine compounds such as sodium hypochlorite to water. The method is used to kill certain bacteria to prevent the spread of waterborne diseases as well as to conserving water quality. Following the chlorination process, it is required that the water supply pipework is tested before a connection is made to the mains water. This is essential to ensure suitability and safety for the provision of drinking water.
All new or modified water systems require to have performed before they can be connected to the mains supply to prevent contamination of the water supply. When new water mains supply is installed to a site, there is a mandatory requirement by the local water authority for the pipework to be flushed and disinfected in accordance with their own specification. Evolution Air & Water Hygiene has a specialist chlorination & microbiological sampling division where we offer in-depth knowledge on all aspects of water hygiene and treatment which follows strict regulations from BS 8558, ACoP L8, HSG 274 and BSRIA guides.
A Chlorination may also take place when:
– In any new installations as part of a building’s commissioning procedure.
– Where major extensions or alterations have been carried out to the water system.
– If regular microbiological sampling provides a positive result on an existing system for high counts of harmful pathogens such as Legionella or Pseudomonas.
– If contamination within the water system is suspected.
– If the water system has not been in regular use and therefore the pipe work has not been flushed regularly
Each chlorination commences with flushing of the system to remove any debris; this will provide a clean base for the chlorination to take place. Following the initial flush, the system is filled with a chlorinated solution which will remain in the system pipework to begin the bacteria killing process. After this contact period has been achieved, we neutralise the solution and dispose of it safely, flushing the system through again with clean water to remove any traces of chlorine. This process is then repeated one more time. Following the final flush, to ensure we are meeting industry standard regulations, the water is sampled for chlorine and sent to a UKAS accredited laboratory for microbiological analysis. Following receipt of the results, we provide a certificate of chlorination, along with a full analytical report for each sample to show what the water contents reflect
