New British Standards 2015

MWS would like to inform our clients that BSI have revised the standards covering disinfection of water systems.  BS8558:2011 is now BS8558: 2015.

Any required microbiological samples should now be taken between 2 and 7 days following the disinfection system.  Please ensure you incorporate this timescale within your construction programme.
