  • Sewer Level Monitoring - Photos

    Sewer Level Monitoring - Photos Photos in this article present the complexity and versatility of sewer level monitoring. When examining the photos, pay special attention to the stand-alone autonomous characteristics of each installation. In lack of any cabling from the outside, whether data cables or power cables, the solution is fed from its own battery power supply. Data is tranmitted ...

  • 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 ...

  • Coupling acoustic devices for monitoring combined sewer network sediment deposits

    Combined sewer networks display some unique features that are not easily reproducible in the laboratory and have yet to be well understood. The transport of organic and mobile sediments, present in large quantities despite the use of optimal design practices, dramatically changes sewer flow patterns and the interaction between flow and sediment. To understand both the flow patterns and transport ...

  • Behaviour of different cementitious material formulations in sewer networks

    Sewer networks are subjected to degradation, including biodeterioration of materials, in the presence of biogenic sulfuric acid, leading to costly repairs. To ensure durable structures, it is essential to select the best adapted materials. Two cementitious materials based on ordinary Portland cement (OPC) or calcium aluminate cement (CAC), were subjected to biodeterioration in the headspace of ...

  • 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 ...

  • Predicting combined sewer overflows chamber depth using artificial neural networks with rainfall radar data

    Combined sewer overflows (CSOs) represent a common feature in combined urban drainage systems and are used to discharge excess water to the environment during heavy storms. To better understand the performance of CSOs, the UK water industry has installed a large number of monitoring systems that provide data for these assets. This paper presents research into the prediction of the hydraulic ...

  • The impact of network simplification on property flood risk predictions

    A recent project, set up to compare the merits of simplified and desimplified models in InfoWorks CS, has proved that the solution’s fast and robust simulation capabilities are now so advanced that highly-complex models can provide far greater accuracy at competitive speeds than smaller, simpler models. As the water industry moves towards a risk-based approach to flooding, the existing ...

  • Mechanism and kinetics of biofilm growth process influenced by shear stress in sewers

    Sewer biofilms play an important role in the biotransformation of substances for methane and sulfide emission in sewer networks. The dynamic flows and the particular shear stress in sewers are the key factors determining the growth of the sewer biofilm. In this work, the development of sewer biofilm with varying shear stress is specifically investigated to gain a comprehensive understanding of ...

  • Getting your money’s worth - collecting and utilizing accurate flow monitoring data for collection system analysis and modeling

     Abstract A comprehensive flow monitoring network can provide powerful insight about the performance of a sanitary sewer collection system. Accurate flow monitoring data reveals numerous system details, such as sewer usage patterns, the presence of sediments, groundwater infiltration, rainfall-dependent inflow and infiltration, stream intrusion, and sewer exfiltration ...

    A comprehensive flow monitoring network can provide powerful insight about the performance of a sanitary sewer collection system. Accurate flow monitoring data reveals numerous system details, such as sewer usage patterns, the presence of sediments, groundwater infiltration, rainfall-dependent inflow and infiltration, stream intrusion, and sewer exfiltration or leakages. Knowledge of these ...

  • Water System Infrastructure – A View of Where We Are, Where We Could Go and How We Can Get There.

    This is the first of several essays that are aimed at focusing attention on water and sewer infrastructure systems. In this essay, the current state of city and regional systems are examined, the current state of the industry will be examined next, investigating some of the tools, resources and technologies that are available, today. Beyond that, the final essay in this series will look at the ...

  • ‘Smart’ flood alleviation system protects Portsmouth

    In late 2014, Southern Water completed a major project to reduce the risk of sewer flooding in parts of Portsmouth and Southsea. Substantial works were undertaken to divert runoff and tidal ingress, and a ‘smart’ hydrometeorological monitoring system was installed to enable prompt diversion of excess water during periods of high rainfall. Sewer level monitoring is undertaken in ...

  • 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 ...

  • Open MI: linking models

    Traditionally sewers and rivers have been modelled separately using different software applications, with outputs from one model being fed into the other. However this does not fully represent the continuous interaction between the two modeled elements. Assessing the impact of sewerage discharges and overland flows from urban areas to watercourses and the subsequent effects of watercourse levels ...

  • Overview of Infrastructure Asset Management A View from Both Sides of the Atlantic Ocean

    AbstractEurope and the United Kingdom (UK) are at the forefront of Asset Management for water utilities. This is primarily due to the fact of privatization of water utilities in the UK. The UK is currently in the third generation of the Asset Management procedures and has well defined methods for identifying and managing assets. In the United Kingdom (UK), large scale Asset Management has been ...

  • City Of West Palm Beach Reaches Out To Community With Proactive Approach To Manage Critical Force Main
