Mains Disinfection and Chlorination (BS8558:2011)

It is now a requirement that new private water supply pipes are commissioned before they are connected to mains water services. WHS provide BS8558:2011 mains disinfection services and sampling of new and existing mains pipework. We work on anything from short lengths of new mains to new mains and full building disinfection prior to connection and handover.
