Can you please advise the number of point-of-use filters used per annum by the Trust to prevent waterborne bacteria exiting the water system. 

Ideally a breakdown giving the number of filters used in 2014, 2015, and 2016.  However if only approximate annual usage figures are available then this will be adequate for our purposes.

The Trust manages a very stringent regime on Legionella and Pseudomonas on all our water plants and only use point of use filters as and when it is required, when/if there is a positive result in an area, the PAL carbon shower heads are used.

It is difficult to determine the usage over the last 3 years as it has been ad-hoc usage.
2016 (calendar) 24 used in the year.
2017 (calendar – until present) 8 x point of use filtered shower heads.
