  • Wastewater treatment plant operators work confidently with complete system measurement

    Wastewater treatment is a vitally important process. Just ask The Township of Edwardsburgh/Cardinal’s Assistant Chief Water and Sewer Operator, Eric Wemerman.  “For a community to keep everyone’s trust you want to make sure you’re operating a good system.” Eric continues.  “It’s important for health reasons, when people flush their toilets you ...

  • Estimation of combined sewer overflow discharge: a software sensor approach based on local water level measurements

    Combined sewer overflow (CSO) structures are constructed to effectively discharge excess water during heavy rainfall, to protect the urban drainage system from hydraulic overload. Consequently, most CSO structures are not constructed according to basic hydraulic principles for ideal measurement weirs. It can, therefore, be a challenge to quantify the discharges from CSOs. Quantification of CSO ...

  • Financing the Clean Water Atlanta Initiative

    ABSTRACTOver approximately a 15-year period, the City of Atlanta will invest nearly $4 billion in its water and wastewater infrastructure, in part to ensure compliance with Consent Decrees entered into in the late 1990s related to Combined Sewer Overflows (CSOs) and Sanitary Sewer Overflows (SSOs). This investment has occasioned execution of a strategic financial ...

  • ASTM Standards Help Meet Need for Clean Water

    The new ASTM Water Portal provides a single access point to standards and related information about ASTM International’s diverse committees working to protect and monitor this vital global resource.

  • Investigation and Forecast Earthquake Damage for Sewage Systems

    ABSTRACTJapan is known as one of the areas where earthquake occurs most to be located in border of oceanic plate and continental plate. On this account, earthquake countermeasures are pushed forward triggered by the great Hanshin earthquake (1995), but measures for existing facilities are not yet enough. In such situation, the mid Niigata prefecture earthquake of October 23, 2004 attacked ...

  • Estimating inflow to a combined sewer overflow structure with storage tank in real time: evaluation of different approaches

    The performance assessment of storage tanks and combined sewer overflow (CSO) structures in sewer systems requires knowledge of the total inflow from the catchment during rainfall events. Many structures are, however, only equipped with sensors to measure water level and/or outflows. Based on the geometry of the tank, expressed as a level-storage relationship, inflow can be calculated from these ...

  • Modelling sewer sediment deposition, erosion, and transport processes to predict acute influent and reduce combined sewer overflows and CO2 emissions

    Understanding of solids deposition, erosion, and transport processes in sewer systems has improved considerably in the past decade. This has provided guidance for controlling sewer solids and associated acute pollutants to protect the environment and improve the operation of wastewater systems. Although measures to decrease combined sewer overflow (CSO) events have reduced the amount of ...

  • The application of improved flow diverter for first flush management

    The paper presents the investigations on first flush phenomenon based on the total suspended solids (TSS) concentration measurement during selected rainfalls at central part of Czestochowa (Poland) and also the hydrodynamic model of the catchment. The model allows to present the conception of first flush management using an improved flow diverter Septurn. Flow diverters used in the separate sewer ...

  • An application of Austrian legal requirements for CSO emissions

    The Austrian standard for designing combined sewer overflow (CSO) detention basins introduces the efficiency of the combined sewer overflows as an indicator for CSO pollution. Additionally criteria for the ambient water quality are defined, which comprehend six kinds of impacts. In this paper, the Austrian legal requirements are described and discussed by means of hydrological modelling. This is ...

  • Who Says Charity has to Cost Money?

    It is a rare and delightful occurrence when altruistic motives and the quest for profit coincide in such a way that following one begets the other.  The reuse and recycling of waste water is just such a project, especially in industrial applications replacing municipal potable drinking water supplies.  When one considers the fact that more than a billion people in the world are without ...

  • 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 ...

  • Reasons to choose Trenchless Pipe Bursting Repairing Equipment

    Trenchless technology has altered the industry, revolutionizing sewer pipe repair and gaining the favor of many property owners today. No digging, no re-landscaping, no use of chemicals- the trenchless strategy is far better than the traditional approach. In the developing business sector, pipe repair companies need the most effective equipment to stay competitive. The ...

  • Heavy Industry Plant Wastewater Treatment, Recovery ang Recycle Using Three Membrane Configurations in Combination with Aerobic Treatment

    ABSTRACTIn the late 1990’s a major diesel engine manufacturing plant began evaluation of wastewater treatment technologies that would improve the quality of wastewater discharge, would produce treated effluent of reduced oil and grease, BOD and COD load suitable as feed to their sanitary waste biological treatment plant, and eliminate the costs and risks associated ...

  • Field campaign on sediment transport behaviour in a pressure main from pumping station to wastewater treatment plant in Berlin

    As part of the project KURAS, the Berliner Wasserbetriebe realized a field campaign in 2015 in order to increase the process knowledge regarding the behaviour of transported sediment in the pressure main leading from the pumpstation to the wastewater treatment plant. The field campaign was conducted because of a lack of knowledge about the general condition of the pressure main due to its bad ...
