CWS Tank Chlorination

Supporting safe operation of cold water storage systems

What CWS Tank Chlorination Involves

CWS tank chlorination involves the controlled disinfection of water storage tanks to reduce bacteria and contaminants. The process is carried out using appropriate methods to ensure effectiveness while protecting the integrity of the tank and connected systems.

Chlorination is often carried out following cleaning, maintenance, or periods of inactivity, helping restore safe operating conditions.

All works are planned carefully to minimise disruption and ensure systems can be returned to service safely.

When CWS Tank Chlorination Is Required

CWS tank chlorination is commonly required when:

  • Tanks have been cleaned or maintained

  • Systems have been out of use for a period

  • Water quality concerns are identified

  • Planned compliance or preventative maintenance is due

  • Tanks are being recommissioned

Regular attention helps reduce health risks and supports compliance with water hygiene requirements.
