How are we tracking?

Indicator: Delivery of capital investment program for renewals/rehabilitation

Water and wastewater

We renew or rehabilitate water and wastewater assets to maintain service performance and to extend their lifespan. Water and wastewater mains are renewed or rehabilitated when it would cost us less to replace them than maintain them.

In 2011–12, we renewed or rehabilitated 63 km of water mains at a cost of about $78 million. This was more than the planned length and less than budgeted. These costs include all water pipes and critical water mains works but exclude water main break repairs. The average unit rate to renew water mains was more in 2011–12 than 2010–11 due to a higher proportion of renewals works in roadways in built-up areas, leading to increased restoration costs.

During the year, we renewed or rehabilitated 48 km of wastewater mains at a cost of $65.8 million. This was slightly more than planned and less than budgeted. The average unit rate to renew or rehabilitate wastewater mains was higher in 2011–12 than in 2010–11, as there was an increase in the ratio of large wastewater mains to wastewater pipes renewed or rehabilitated.

Information technology

In 2011–12, we spent $46 million on information technology renewals and business efficiency projects. This was $10 million less than planned as some technical solutions were less complex than originally estimated.

We completed a number of major projects in 2011–12 including:

  • an upgrade of the MS Office (2000) suite and related products to MS Office 2010

  • transition of the operation and support of Sydney Water’s meter reading system to Sydney Water.

The following major projects were underway in 2011–12 including:

  • redesign of the Sydney Water website

  • a new incident recording system to record and help manage threats to safety and the environment, interruption of services to customers, and serious public complaints.
