It’s based on a series of measures which include non-compliance of our water treatment works sites and reservoirs due to coliform bacteria, turbidity and the number of reactive equipment failures. About the data More information regarding this performance commitment can be found here (https://www.yorkshirewater.com/media/1548/yorkshire-water-annual-performance-report-apr-2018-2019.pdf)on page 216 and on rows 1-6 of page 214 for the data tables to which the data refers to. Technical details specific to reference bandings Reference and Upper Reference refer to the bandings that determine whether a performance commitment is improving, stable or deteriorating, with an overall assessment taken by way of a calculation of the sub-measures (rows 1-6 page 214 as detailed above). The first assessment is the overall status of the main S&R measure as either; Improving, Stable or Deteriorating. This assessment is reported annually with confirmation of the end of AMP position made in year four based on the year five forecast outturn position. Sub-measures will be judged as either Stable, Improving or Deteriorating depending on their position in relation to the reference levels set at PR14 and confirmed in Ofwats ‘FD[final determination] Outcome and ODI[outcome delivery incentives] base dataset’. The number of sub-measures’ categorisation will then be aggregated to confirm the overall assessment for the overall S&R measure.
