How long will stormwater pipelines really last?
The use of the straight-line depreciation based on age, for stormwater pipe networks, generally results in the reporting of excessive depreciation in the early phase of the portfolio's lifecycle. These assets, like many other pipeline systems, perform at or near as-new performance for most of their life with accelerated deterioration in the late stages. A more representative basis for determining deterioration is the use of structural condition analysis. However the development of condition based depreciation models for reinforced concrete pipe (RCP) stormwater pipelines is hampered by the lack of available data on current condition and deterioration mechanisms upon which to base the analysis. This paper describes the development of a methodology and model for Logan City Council's-RCP stormwater pipelines that can be implemented, in a cost effective manner, to calculate condition based deprecation to much better represent the actual deterioration and hence depreciation of the stormwater assets.
