8      Asset Management Practices

This section outlines the systems and processes used to make decisions on how the
stormwater assets will be managed. Business practices are broken down according to the
Data, Information Systems and Processes to help identify the information needs of the
stormwater activities.

              •     Data: Data available for manipulation by information systems to produce the
                    required outputs.
              •     Information systems: The information support systems used to store and
                    manipulate the data.
              •     Processes: The necessary processes, analysis and evaluation techniques
                    needed for life cycle asset management.

The Asset Management Improvement plan appearing in Section 9 details development
priorities, timetables, resources and some costs.
