At Logan Logan City Council's (LCC) Financial Sustainability Strategy
identifies and plans to address some concerns over Council's future forecast net operating surplus/deficits which have been and are forecast to be in deficit for a number of years.
Council's forward estimates presented in the strategy indicate that due to the levels of depreciation, Council's operating revenues will need to be increased even further to match Council's operating costs.
As it stands throughout the 10 year time horizon of the model, Council is not fully funding depreciation.

Why SW AM Project?
• to assist with Council’s financial sustainability in the era of demanding funding priorities, growing and expanding asset bases and increasing community expectations
• to understand the abnormality between the renewal expenditure trend and demand in comparison to historical financial reporting which was based on traditional accepted useful lives.

SW Asset Mgmt
• Improving the data quality, confidence and performance expectation of SW Assets.
• The significance of the asset data, current replacement costs and life expectancy has drastically increased as Australian Local Governments have been required to adopt accrual accounting practices and meet related regulations.– Advanced maturity/ research/ modelling in road space
but SW still poor cousin!!

Focus
Enhancing asset management strategies to strengthen financial sustainability
– Asset management strategies towards the long term viability
– Reflecting on the strategies of optimal treatments and asset performance through improved knowledge/ confidence and evidence

How - Methodology
• Know me to be informed:– Review of asset register & componentization*, – unit rates, – renewal project data and condition data to
recommended appropriate useful lives, – unit rates and valuation methodology to be supported
by additional condition data capture/ assessment• Simple analogy to Roads (Seal/ Surface,
Pavement, Subbase, Earthworks)

Key ingredients
• Stormwater Pipes, Pits, Headwalls and Culverts better aligns with modern asset management practices
• Renewal (relining, part pit rehab) from no. of projects and industry research– Greater than 1m deep, 600m or larger, a good
economical candidate of renewal treatment• Pipe, trench (incl of base)
![Page 12: Enhancing Asset Strategies to strengthen financial sustainability](https://reader036.vdocuments.us/reader036/viewer/2022070518/58e4fb181a28abdf698b59af/html5/thumbnails/12.jpg)
Continue…• incorporating asset performance observations
(CCTV, age and historical field knowledge)– 6km of 1200km pipe network
• Risk based sampling– Visual validation (of no significant issues)
• Unit rates review– National benchmarking (JRA and associates)

Outcome
• The improved alignment of Asset Management practices and financial reporting of stormwater assets has resulted in a $6.4 Million reduction in annual reported depreciation.
• This is a material reduction in depreciation expense for this asset portfolio.

Next phases
Collaboration, resource sharing and open data (across Public Sector)
• Further componentation (reflection of design, construction and asset life cycle practices)
• Seeking support and collaboration from many Councils for additional evidence and calibration
• Opendata standard for asset management data sharing
• Industry collaboration and research partners• Learning and knowledge share with other pipe
asset owners (water, wastewater and gas)

Collaboration
The larger the •benchmarking base, •asset performance data, •supporting analysis and input
for collective intelligence from industry, the broader and robust would be the methodology and outcomes for all of us to share and benefit from
