Properties supplied by a single source - This is a continuation of a measure developed for 2010-15 relating to delivery of the water supply grid; it measures the number of properties that are solely supplied by one source of drinking water and cannot be fed from an alternative one.
We are targeted with reducing the number of these properties to 78,000 in 2015-16 with a further reduction to 42,000 in 2018-19.
If we were to fail to meet the target in any given year due to delays in delivery of the grid we would refund customers £76.60 per property above target per year. If we de-scope the integrated supply grid and fail to deliver these improvements, we will refund customers £2,445 per property - there is no risk of this as all associated schemes are currently under construction.
The implementation of the water supply grid in 2017/18 has meant that the PC target has been met in 2018-19.
