        Stormwater Infrastructure Operations & Maintenance Plan
Operational and maintenance activities are fundamental for the ongoing management of the
Stormwater Infrastructure; it is considered an investment rather than a liability. The Stormwater
Infrastructure assets rely on operational and maintenance costs for the serviceability of the assets
identified in this plan. These activities are a significant annual investment that directly influence the
potential for Stormwater Infrastructure assets to reach its intended service life. The ongoing
development of asset knowledge through asset inspections, improved maintenance activities,
subsequent defect monitoring and repairs are fundamental in developing sustainable intervention
levels for renewals and replacement of Stormwater Infrastructure assets.

Table 2: Annual Operational & Maintenance Costs by Asset Group

Maintenance and operational costs are identified to ensure council understands the whole of life
costs associated with the day-to-day management of Stormwater Infrastructure assets. The figure
below identifies the long term financial commitment required in maintaining assets. In order to
maintain assets to an acceptable level, the cumulative investment over a ten-year period will equate
to $42m. It is proposed to develop a more detailed list of operational and maintenance activities per
annum by asset class and utilise the T1 asset management system to identify maintenance by the
breakdown of asset classes within the Stormwater Infrastructure asset classes. In addition, more
detailed and longer term planning for maintenance has been identified as an improvement from this
AMP.
