  • Monitoring accumulation sediment characteristics in full scale sewer physical model with urban wastewater

    A series of experiments were carried out with real wastewater in a pilot flume located at A Coruña wastewater treatment plant (WWTP) (Spain). A full scale model was developed to test a circular (300 mm inner diameter) and an equivalent area egg-shaped plastic pipe under controlled experimental conditions (pipe slope 2–5‰, averaged discharge Q = 4 L/s). Velocity profiles and sediment ...

  • Assessment of erosion and sedimentation dynamic in a combined sewer network using online turbidity monitoring

    Eroded sewer sediments are a significant source of organic matter discharge by combined sewer overflows. Many authors have studied the erosion and sedimentation processes at the scale of a section of sewer pipe and over short time periods. The objective of this study was to assess these processes at the scale of an entire sewer network and over 1 month, to understand whether phenomena observed ...

  • Quantifying Sub-Surface Discharges from Individual Sewer Defects

    ABSTRACTThe California Regional Water Quality Control Board, Santa Ana Region (RWQCB) required wastewater collection agencies in Orange County to report discharges from “pipe breaks, leaking sewer pipes and joints, and other subsurface discharges of wastewater.” The Orange County Sanitation District (OCSD), in conjunction with a research team from University of California, Irvine (UCI), developed ...

  • Report to Congress: Combined Sewer Overflows to the Lake Michigan Basin

    The U.S. Environmental Protection Agency (EPA) is transmitting this Report to Congress on combined sewer overflows (CSOs) in the Lake Michigan basin. CSOs can occur in combined sewer systems (CSSs), which are defined as collection systems that carry both wastewater and storm water in the same pipe. A CSO is defined as “the discharge from a CSS at a point prior to the publicly-owned treatment ...

  • Robot Device for Pipe Inspection - Case Study

    In 2005, Pure Technologies (Pure), a provider of various structural monitoring and leak-detection technologies, set about to develop a pipeline assessment tool that could monitor and report on the condition of pre-stressed concrete cylinder pipes (PCCP) utilized in municipal water and sewer systems. The tool’s competitive advantage would be accurate assessment decoupled from the need to ...

  • Developing dry-weather flow and RDI/I models using regression analysis and unit hydrography

    InfoWorks CS has been used to build an accurate sanitary sewer flow model for Jefferson Parish, Louisiana, despite there being gaps in the available input data. Reliable predictions of the dry-weather and rainfall-dependent flows were derived by using techniques including unit hydrography and regression analysis to determine the required parameters. Jefferson Parish is close to New Orleans in the ...
