Sewer Deterioration Model for Asset Management Strategy

Asset management is an increasing concern for wastewater utilities and municipalities. In the last 30 years, most cities have invested in sewer system expansion and treatment plant upgrade but a relatively small component has been allocated to the improvement of sewer system condition.

SEMA aimed to assess the suitability of sewer deterioration models to predict sewer condition state. The quality of prediction of a deterioration model was carefully evaluated using the extensive inspection dataset of different cities. The model is able to simulate the general condition of distribution systems at the network level and to identify sewers in poor condition at pipe level. The results underline the potential benefits of using deterioration models to support asset management strategies.
