  • 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 Need for a Total View of Water Networks

    The water industry is not short of software offerings, and so the arguments in favour of yet another software program had better be very good indeed. In this article we examine how one very significant community of users – operations managers, engineers and planners - have largely had their specific needs overlooked; we identify the type of system needed to fulfil their requirements and the ...

  • 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 ...

  • Monitoring micropollutants in the Swist river basin

    Micropollutant pathways were studied for the Swist river basin (Western Germany). The aim was to verify the effectiveness of a monitoring approach to detect micropollutants entering the river. In a separate sewer system, water was frequently found to be contaminated with micropollutants. Improper connections of sewage canals to the stormwater network seemed to be the cause of pollution. ...
