  • Municipal sewer remote monitoring

    Sewers are critical heavy duty infrastructure components requiring costly maintenance. Many municipalities suffer from ageing pipelines that pose higher chances of failure. Sewer leak or overflow results in high cost as a result of civil reimbursement and due to inflected illness. Moreover Civilian frustration that results form the overflow is often targeted towards the municipality. Overflow can ...

  • 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 ...

  • Evaluation of effectiveness of combined sewer overflow control measures by operational data

    The effect of combined sewer overflow (CSO) control measures should be validated during operation based on monitoring of CSO activity and subsequent comparison with (legal) requirements. However, most CSO monitoring programs have been started only recently and therefore no long-term data is available for reliable efficiency control. A method is proposed that focuses on rainfall data for ...

  • 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 ...

  • Sewer mining to supplement blackwater flow in a commercial high-rise Australia-Sydney case study

    Project Background or Rationale Australia’s warm climate and habitual droughts have resulted in innovative water conservation practices in commercial developments, such as 1 Bligh Street in Sydney. Commissioned in May 2011, the highly acclaimed 29 story office tower overlooking the Sydney Harbor captures nearly 100 percent of its wastewater and reuses it in the building. By recycling ...

  • Case study - City of Sault Ste. Marie - Pressure Monitoring

    The condition assessment project consisted of a Sahara pipeline inspection to detect any leaks or pockets of trapped gas on the lines, as well as a period of pressure transient monitoring on each pipeline to check for any sudden peaks or drops in the pressures which could be damaging to the lines. Service: Sahara Transient Pressure Monitoring Client: City of Sault Ste. Marie Type of ...
