Monitoring Deterioration in a Catchment’s Sewerage System

Abstract

Groundwater seepage through cracks in the sewerage pipeline is a major maintenance issue in most cities’ sewer networks. The more the sewer pipes crack – and the wider these cracks are – the worse the rainfall seepage problem becomes. The total volume of rainwater seepage into the sewer pipes for a catchment is correlated with deterioration and can therefore be used to estimate the rate of deterioration. This paper describes a monitoring system that can be used to identify significant trends in sewer deterioration. Effective monitoring by asset managers can highlight the need for early maintenance such as removing tree roots from pipe cracks and patching the cracks.

Data Interpretation and Continuous Modal Parameter Identification of Cable Stayed Bridge

“…In the past three decades, researchers have tried to establish effective techniques for monitoring civil structures. However, the unpredictable nature of civil structures due to the anomalous data obtained from these structures and the nonlinear behavior of these structures makes the monitoring process more complex, Spark and Kasmarik [3], and so the data interpretation becomes more and more essential, Khan et al [4]. The enormous amount of data obtained from these sophisticated measuring equipment installed at these civil structures, specially the long span cable stayed bridges, needs to be reliable, so that an accurate and detailed data analysis can be performed effectively, Cross et al [5].…”
