  • Ground drainage with Filtram

    The A11 Thetford Bypass comprises approximately 7.5km of single and double carriageway. The design called for a roadside fin drain system to act as a vertical water flow interceptor in conjunction with a horizontal under channel drainage layer incorporated within the roadbase. The combined system discharges to conventional drainage outlets. Filtram 1B1 -ED was chosen as the vertical fin drain and ...

  • Acid mine drainage treatment

    Acid mine/rock drainage is a rampant problem in the world today. The above photo depicts acid drainage at an abandoned mine in the Yukon Territory of northwest Canada. This mine shares a similar history to thousands of other mines throughout the world. It was in operation for six short years in the 1950’s, producing gold ore. Its profitability eventually failed and it was abandoned. In the ...

  • Decision Analysis Applications for the Sustainability of Global Urban Water Resources and Drainage Systems

    ABSTRACTWater is one of the most vital elements needed for life. In many countries water supplies, especially for critical drinking water, are either being depleted or polluted. Too often these problems are magnified due to the lack of reliable drainage systems that provide proper stormwater and sanitary sewage collection and treatment of human generated wastewater. ...

  • Comparative analysis of the outflow water quality of two sustainable linear drainage systems

    Three different drainage systems were built in a roadside car park located on the outskirts of Oviedo (Spain): two sustainable urban drainage systems (SUDS), a swale and a filter drain; and one conventional drainage system, a concrete ditch, which is representative of the most frequently used roadside drainage system in Spain. The concentrations of pollutants were analyzed in the outflow of all ...

  • Distributed tree-based model predictive control on a drainage water system

    Open water systems are one of the most externally influenced systems due to their size and continuous exposure to uncertain meteorological forces. The control of systems under uncertainty is, in general, a challenging problem. In this paper, we use a stochastic programming approach to control a drainage system in which the weather forecast is modeled as a disturbance tree. Each branch of the ...

  • Drainage System Stabilization Project case study

    In 1997, a residential development was built upslope from this golf course drainage ditch. It began to erode, but because the ditch was filled with invasive species such as Blackberry and Reed Canary Grass, the erosion was not visible. When the non-native plants were removed to create a new golf course hole, the erosion was evident – in some places more than four feet deep, all the way ...

  • A new litter trap for urban drainage systems

    ABSTRACTLitter is generated in shopping areas and is washed or blown into stormwater drainage systems. These convey the litter to open water bodies leading to the accumulation of non-biodegradable litter on the banks and beaches of urban waterways and bay foreshores. The increasing public awareness of the problem prompted the State Government of Victoria to provide funding to develop an ...

  • Drainage-Area Survey Data Management

    Northumbrian Water Supply of HydroLog4 time-series database and reporting system for drainage area studies Northumbrian Water ordered HydroLog4 as a replacement data management and reporting system for time-series data collected during the short and long-term survey work by internal crews throughout the water company's wastewater management business. ...

  • Modelling Sustainable Urban Drainage Structures

    Introduction “Sustainable Development” is an increasingly important concept in most industries today, and one in which the water industry has been making rapid progress for over a decade. In countries around the world, including the USA, Europe, and Australia, Sustainable Urban Drainage (SUD) structures - permeable pavements, ponds, and the like - are reducing the volumes of direct urban runoff, ...

  • Disposal of drainage water in fresh water of Sindh Province, Pakistan

    The mankind has been settling and hebetating their villages, towns and cities beside banks of rivers and natural or artificial streamline of water resources for many thousand years. In the initial era, people pass their lives in jungle and woods and they get food from raw material. But when they gradually thought to live together for passing social life, they knew that individual could not ...


  • ACO drainage channels form an extensive sustainable drainage system at refurbished M5 services

    At the refurbished Michaelwood Services on the M5, engineers have been able to combine the benefits of different high performance ACO Water Management drainage channels to complete an extensive sustainable drainage scheme that adds some striking visual features to the new parking areas. Installed at the services on both sides of the carriageway, the drainage systems use ACO products that provide ...

  • Hydrochemical changes in a reservoir that receives water contaminated by acid mine drainage

    The aim was to characterize hydrochemical changes that take place in the Sancho reservoir, which receives waters contaminated by acid mine drainage (AMD) from the Meca River (Iberian Pyrite Belt, SW Spain). The sampling procedure comprised bimonthly campaigns carried out between October 2011 and May 2012, in the entrance of the reservoir and in the input river waters. In addition to in situ ...

  • Experimental and numerical investigation of interactions between above and below ground drainage systems

    This paper presents the results of the experimental and numerical investigation of interactions between surface flood flow in urban areas and the flow in below ground drainage systems (sewer pipes and manholes). An experimental rig has been set up at the Water Engineering Laboratory at the University of Sheffield. It consists of a full scale gully structure with inlet grating, which connects the ...

  • Fate of hydrocarbon pollutants in source and non-source control sustainable drainage systems

    Sustainable drainage (SuDs) is an established method for managing runoff from developments, and source control is part of accepted design philosophy. However, there are limited studies into the contribution source control makes to pollutant removal, especially for roads. This study examines organic pollutants, total petroleum hydrocarbons (TPH) and polycyclic aromatic hydrocarbons (PAHs), in ...

  • Past, present, and future design of urban drainage systems with focus on Danish experiences

    Climate change will influence the water cycle substantially, and extreme precipitation will become more frequent in many regions in the years to come. How should this fact be incorporated into design of urban drainage systems, if at all? And how important is climate change compared to other changes over time? Based on an analysis of the underlying key drivers of changes that are expected to ...
