When should pipes be chlorinated?

Water can be a notorious carrier of bacteria and South West Water are rigorous in their safeguarding of the mains water supply. Certain types of private water pipe have to be disinfected (chlorinated) before South West Water will allow connection to their main. Pipes must be chlorinated in the following instances:

  • internal pipe diameter is greater than 50 mm
  • length of supply is over 50 metres
  • where there has been suspected contamination (eg fouling by sewage, drainage or animals)
  • where a system has not been regularly used or flushed
  • where the supply is being converted from a private supply eg borehole, well, natural spring
