Volume of leakage - The total daily volume of water we lose from our distribution system.
We have 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. If we miss the target we are penalised by £305k for every Ml/day we are over, but if we beat the target by over 1 Ml/day, we can receive an incentive payment of £110k for every additional Ml/day.
In 2018-19, we achieved 66.4 Ml/d, which is under the target of 67.2 Ml/d. This figure is within the outperformance payment deadband so no financial payment applies. We have trialed a number of new technologies this year such as satellite and drone leak detection and are also investing in mobile and fixed acoustic networks to enable quicker detection and repair of leakage. As a response to tightness in the external labour market for skilled leakage staff, we have promoted and developed a significant number of leakage trainees in the last 12 months. We expect our efforts to result in further leakage reduction in following years and will help in delivering the tightening target in 2019-20.
