  • Modeling of Sedimentation in Stormwater Detention Basins

    ABSTRACTTo minimize the non-point source pollution from roadway surface, the Texas Department of Transportation (TxDOT) initiated a research project for design of a small footprint non-proprietary detention basin, which consists of pipes and box culvert sections with specialized inlet and outlet system. A conceptual model was developed to estimate particle removal efficiency of the rectangular ...

  • Characterisation and settling of solids in an open, grassed, stormwater sewer network detention basin

    ABSTRACTThe objective of the study is to develop new operational management practices for detention tanks during rainfall events in order to limit flooding risk and, at the same time, to reduce pollutant discharges by optimising the settling process. This paper presents the results of the characterisation of settled particles in an open stormwater detention basin with grassed banks and bottom, ...

  • Controlling the flow: innovative screening device solves detention maintenance issues

    Untitled Document A nine-year, $5.29 million road improvement joint venture between the City of Beaverton, Ore. and Washington County widened 5,680 feet of a two-lane ...


  • Inclined Plate Settlers to Treat Stormwater Solids

    ABSTRACTIt has been well-documented that, in stormwater runoff, many of the problem pollutants are associated with the particulate fraction. Past characterization of urban runoff and source contributions has shown the following: (a) soil disturbance increased the TSS and turbidity in the runoff; and (b) correlations were observed between TSS and particulate runoff concentrations of chromium, ...

  • 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 ...

  • Residential system design

    Rainwater systems can be as simple as placing a rain barrel beneath a downspout or they can be complex – engineered multi-tank systems with pumping stations and automated computer controls for supplying commercial and industrial process applications. Consider that in one installation in the Sumo arena in Japan, rainwater is supplied for flushing toilets and the cistern’s excess ...

  • Wallingford solutions enable an integrated approach to modeling

    Of the many advantages to Wallingford Software’s InfoWorks suite of solutions, one that is particularly valued in today’s demanding modeling environment is their reputation as the gold standard for integration. The solutions allow one interface to answer a wide range of questions, rather than requiring a user to laboriously work through a range of modules or packages. Such key but separate ...

  • Cities are finally treating water as a resource, not a nuisance

    From Houston to Melbourne, the surprising ways urban areas are dealing with water woes Memorial Day barbecues and parades were thwarted this year in Houston when a massive storm dumped more than 10 inches of rain in two days, creating a Waterworld of flooded freeways, cars, houses and businesses, leaving several people dead and hundreds in need of rescue. ...
