Mains & Building Disinfection

New installations or old buildings with low or no usage (such as water systems in buildings that have been mothballed) will need disinfection to clear out the stagnant and stale water prior to use. This commissioning or re-commissioning is vital to ensure clean fresh water is available.

This is especially relevant at the moment where buildings have been underused due to the COVID-19 lockdown. As this eases the risk from legionella, e.coli and other bacteria in the stagnant water becomes more pressing.
Disinfection is vital for ensuring water quality, maintaining acceptable chlorine levels and ensuring regular cleaning of chlorine residual.

Buildings can be disinfected through the CWS tank or via the mains inlet, using our dedicated injection and flushing equipment, and completed to PD855468 or BS8558, alongside any additional requirements of specific water authorities.

DISINFECTING BUILDING WATER SYSTEMS

Recent examples of urgent works include the disinfection of NHS A&E wards, public houses and libraries, offering water treatment for public health benefits. Our water hygiene services handle disinfection and chlorination of pipework, water storage tanks and the water mains.

Both internal water supplies and external, or new mains, water supplies require specific disinfection services. These water system disinfection processes include pipework chlorination, which is the process of disinfecting both internal hot water and cold water system, as well as necessary requirements from local water authorities, which can call for a building’s pipework to be flushed, disinfected and treated before any mains supply can be connected.

Water treatment, mains chlorination, and pipework disinfection services are also required during such times as:

  • Cases of microbiological sampling yielding positive results for the likes of legionella bacteria, e.coli, and other harmful pathogens
  • In the event of new installations being added to a building’s commissioning procedure, including extensions or alterations to a current water system
  • When a building’s water system has remained idle for a lengthy period of time and requires a disinfection process in order to resume regular use
  • If drinking water or potable water is suspected of contamination, whether the cause or origin is believed to be the water supply, the distribution system or the supply pipes 

WATER TREATMENT & DISINFECTION PROCESS

Our Mains & Building Disinfection process aims to aid with any water treatment requirements, ensuring good water hygiene and adhering to building regulations. The disinfection process varies from building to building, taking specific precautions for private water supplies or special buildings, though our efforts are always conducted in a manner that conforms to local water authorities and the Legionella Control Association.

This water treatment process includes:

  • Risk assessment and method statement for chlorination works
  • Mains water flush, clearing the water system and the pipework
  • Thorough disinfection, utilising appropriate chlorine levels
  • Repeated system flush, ensuring all disinfectants are cleared from the mains supply 
  • Confirmation of disinfection, using microbiological sampling in order to test for legionella, TVC, E-coli and any other harmful pathogens
