  • DFW direct bury of storm sewer case study

    Airport Solutions North Texas Contracting has placed the first HOBAS pipe at DFW International Airport in the Dallas/Fort Worth mid-cities. That first installation was a repair to an 84-inch corrugated steel culvert that had failed and created a sink hole approximately 30 feet deep and almost 20 feet in diameter after a series of heavy rains in 2007. North Texas Contracting of Keller, Texas ...

  • When is a Sewer not a Sewer

    Any Sewer is a Sewer –isn’t it? If you were to ask the average man on the street what happened to the water that left his house via the myriad of drain pipes, overflows, soil stacks, gutters, sewer pipes etc would he really know what happened to it? Do consumers actually know or understand that there are different sewers running under their feet? In an effort to control the spiralling ...

  • Decision making in flood risk based storm sewer network design

    It is widely recognised that flood risk needs to be taken into account when designing a storm sewer network. Flood risk is generally a combination of flood consequences and flood probabilities. This paper aims to explore the decision making in flood risk based storm sewer network design. A multi-objective optimization is proposed to find the Pareto front of optimal designs in terms of low ...

  • Do storm event samples bias the comparison between sewer deposits contribution?

    Previous researches demonstrated the occurrence of unique in-sewer sediment, the organic layer, on the Marais site in Paris, capable of explaining the entire wet weather sewer production of suspended particles. Other studies on sites having no similar organic sediment, Clichy in Paris and Ecully in Lyon, demonstrated a wet weather sewer deposits contribution (SDC) to effluent pollution ...

  • Different erosion characteristics of sediment deposits in combined and storm sewers

    To investigate the different erosion patterns of sediments in combined and storm sewers, sediments from three separate sewer systems and two combined sewer systems in urban Shanghai were collected for the flushing experiments. These experiments were conducted with different consolidation periods and shear velocities. As the consolidation period increases, dissolved oxygen exhibits a positive ...

  • Integration of urban runoff and storm sewer models using the OpenMI framework

    This paper presents an integrated modeling approach that combines the legacy urban runoff and the legacy storm sewer models with data exchange at runtime to simulate sewer flows with real-time rainfalls. A software system called IRES has been developed to demonstrate the proposed approach. IRES uses the RUNOFF and the EXTRAN block of Storm Water Management Model (SWMM) as the legacy urban ...

  • Assessing dry weather flow contribution in TSS and COD storm events loads in combined sewer systems

    Continuous high resolution long term turbidity measurements along with continuous discharge measurements are now recognised as an appropriate technique for the estimation of in sewer total suspended solids (TSS) and Chemical Oxygen Demand (COD) loads during storm events. In the combined system of the Ecully urban catchment (Lyon, France), this technique is implemented since 2003, with more than ...

  • A pattern-oriented approach to development of a real-time storm sewer simulation system with an SWMM model

    This paper documents a real-time storm sewer simulation system (RTS4) in conjunction with a Storm Water Management Model (SWMM) based on a pattern-oriented approach. The RTS4 is initiated by system analysis ascertaining functional requirements, which is sequentially followed by conceptual model, pattern languages, concrete pattern-based design, implementations and applications. The proposed ...

  • Searching for storm water inflows in foul sewers using fibre-optic distributed temperature sensing

    A major drawback of separate sewer systems is the occurrence of illicit connections: unintended sewer cross-connections that connect foul water outlets from residential or industrial premises to the storm water system and/or storm water outlets to the foul sewer system. The amount of unwanted storm water in foul sewer systems can be significant, resulting in a number of detrimental effects on ...

  • Integration of transfer function model and back propagation neural network for forecasting storm sewer flow in Taipei metropolis

    Typhoons and storms have often brought heavy rainfalls and induced floods that have frequently caused severe damage and loss of life in Taiwan. Our ability to predict sewer discharge and forecast floods in advance during storm seasons plays an important role in flood warning and flood hazard mitigation. In this paper, we develop an integrated model (TFMBPN) for forecasting sewer discharge that ...

  • Storm Water Plan Case Study

    Global was contracted by a local Road Commission site. The Road Commission site serves as the county level road agency, which maintains more than 1,813 miles of roads and streets and over 250 signalized intersections. The Road Commission contains six sites across the county. Each site is responsible for its particular area. The sites all include maintenance garages, diesel and gasoline ...

  • Compost in the mix for storm water management

    Bioretention areas, also known as rain gardens, are increasingly being used to capture and treat storm water runoff from impervious surfaces such as roofs, sidewalks and parking lots. These landscaped areas often feature native plants installed in an engineered soil mixture that includes compost. “Bioretention areas or rain gardens are an attractive storm water Best Management Practice (BMP) ...

  • Cost effectiveness of centralised and decentralised storm water treatment

    As part of a research & development project commissioned by the Land of North Rhine-Westphalia's Ministry for the Environment and Nature Conservation, Agriculture and Consumer Protection (MUNLV) an examination is being carried out of the general possibilities for centralised and decentralised treatment storm water runoff to be discharged into (canalised) receiving waters and the costs ensuing ...

  • Groundwater intrusion into leaky sewer systems

    Vast volumes of groundwater are drained by urban sewer systems. This unwanted flow component intrudes into sewer systems through leaky joints or connected house drains. However, unlike urban storm drainage, it has a high seasonal variation corresponding to groundwater storage and long slow recessions similar to baseflow in rivers also fed by shallow groundwater exfiltrating into the surface ...

  • Multifaceted sewer improvements program eliminates sewer connection moratorium and system overflows

    The sewer system serving Borough of Jewett City, Connecticut dates from the late 1800’s and was originally constructed as a combined sewer system with the discharges directed to the area rivers. In the 1970’s, the raw sewage discharges from the Borough system were removed from the rivers and redirected to a newly constructed wastewater treatment facility. However, the overflows from the ...

  • An Investigation into the Water Quality of the Charleston Peninsula Storm Drains

    Since the late 1980’s, the South Carolina Department of Health and Environmental Control (SCDHEC) has expressed concern over extremely high fecal coliform counts found in several of the many storm drains that discharge from peninsular Charleston (City of Charleston, 1998). Although the City of Charleston is responsible for the fifty-plus storm drains, Charleston Water System wants to determine if ...
