To minimise water loss from burst mains, a change in practice was introduced in late January 2007. Water is turned off as soon as the field operator arrives at the burst, which means that customers may be without water for longer, but it saves significant volumes of water. The change of practice has resulted in an increase in the average duration of unplanned water supply interruptions and therefore an increase in GSL payments. The 2008-09 target we will be working to is 169.8 minutes.
Looking ahead:
In light of this change in practice, a revised performance target has been determined for future years. We intend to maintain a focus on this target through real time monitoring of performance to minimise customer impacts.
