Volume of water leaked - The total daily volume of water we lose from our distribution system.
We targeted a 5% reduction from our 2014-15 performance of 70 Ml/day, applied as a tightening of the target by 0.7 Ml/day each year up to 2020.
This performance commitment has the potential for both customer refunds and incentive payments. We are penalised by £305k for every Ml/day we miss the target. But, if we beat the target by more than 1 Ml/day, we can receive an incentive payment of £110k for every additional Ml/day.
In 2019-20, we achieved 61.4 Ml/d, which is under the target of 66.5 Ml/d. As a result, we will receive an outperformance payment of £330,000. We have met this commitment for each year of the 2015-2020 regulatory period.
The mild wet winter of 2019-20 has contributed to this performance, as well as responding to 90% of customer reported leaks within 24 hours (a further PC). We have increased our use of fixed acoustic loggers to detect leaks, supported by a newly formed team looking at mobile acoustic loggers. In addition, we have optimised existing pressure control assets, and continue to make progress on further improvements in methods to reduce leakage. This commitment continues in a revised form for the 2020-2025 regulatory period.
