  • Performance of a pilot-scale constructed wetland for stormwater runoff and domestic sewage treatment on the banks of a polluted urban river

    To examine the performance of a constructed wetland system on stormwater runoff and domestic sewage (SRS) treatment in central east China, two parallel pilot-scale integrated constructed wetland (ICW) systems were operated for one year. Each ICW consisted of a down-flow bed, an up-flow bed and a horizontal subsurface flow bed. The average removal rates of chemical oxygen demand (CODCr), total ...

  • Resilience in the context of a stormwater infrastructure report card

    This article is a product of an independent study effort accomplished over the span of two semesters at the US Air Force Academy. The authors set out with the intent of investigating the state of current thought regarding resiliency as it applies to domestic public infrastructure systems. In order to bridge the gap between theory and practice, an American Society of Civil Engineers local ...

  • How to Plan Stormwater Management for Urban Areas

    Water is a vital commodity in our lives, but it is possible to have too much water all at once in our lives, especially following violent storms or snow melt. This excess water, lying on the ground, swelling rivers, canals and drains to over-capacity is known as stormwater. In order to make the best use of this water, local authorities need to safely contain stormwater while any ...

  • Characterization and source identification of stormwater runoff in tropical urban catchments

    The characteristics of urban stormwater pollution in the tropics are still poorly understood. This issue is crucial to the tropical environment because its rainfall and runoff generation processes are so different from temperate regions. In this regard, a stormwater monitoring program was carried out at three urban catchments (e.g. residential, commercial and industrial) in the southern part of ...

  • Pilot plant study for one year: water quality management and algal control of sustainable urban stormwater ponds

    Pond structures as cost-effective "source control" drainage techniques that can be applied to reduce the risk of downstream flooding and to recycle stormwater. There are no widely accepted performance and water quality management data on stormwater ponds, yet there is a need for operation and maintenance guidelines, coupled with data on reliability, economics and public acceptance. The purpose of ...

  • Constructed Wetlands I

    Traditional constructed wetland are shallow planted basins for cleaning anthropogenic discharges (wastewater or polluted runoff). They were used for cleaning of: domestic wastewater agricultural wastewater coal mine drainage stormwater runoff The main construction elements were: inflow ( e.g. sedimentation part) substrat (soil ...

  • Long Term Full Scale Comparison of Activated Sludge (AS) With Biological Aerated Filter (BAF)

    The Wastewater Treatment Plant (WWTP) of Frederikshavn, Denmark, was extended in the early nineties to increase its average daily flow to 4,5 MGD (16,500 m³/d) and meet new requirements for nutrient removal (8 mg/l TN, 1,5 mg TP/l). A parallel biological aerated filter (BAF) was the selected as the most economical upgrade of the existing activated sludge plant (AS), and started up in 1995. ...

  • A fresh approach to water practices

    Science is meeting the challenge of finding ways to reduce Australia's wasteful water practices and improve the way we use and manage this finite resource. In the regional NSW town of Goulburn, just down the road from Australia’s national capital, water supplies earlier this year fell to less than 10 per cent of capacity. In most of Australia’s major cities demand is close to or equalling supply ...

  • Wastewater Reuse and Minimisation: Weatherall Smash Repairs

     Weatherall Smash Repairs took the initiative on cleaner production because the owner and staff wanted to help the environment. They’ve been rewarded with savings that will grow as water and disposal costs continue to increase, gains in productivity, and a future marketing advantage. They may also be able to sell the water recycling system they have developed, giving a further financial ...


  • Optimizing Wastewater Treatment

    ' Growing volumes of both industrial and municipal wastewater are being discharged to surface waters but the treatment provided frequently is inadequate to protect the desired uses of the receiving waters. With limited resources in terms of both institutional capacity and finance, governments face difficult choices in optimizing their investments in municipal systems and establishing practical ...

  • Suburban sprawl doesn’t have to be ecologically devastating

    As development gobbles up open space, conservationists take a fresh look at subdivisions with biodiversity in mind. Fort Collins, Colo., is a growing, vibrant college town with a typical American problem: Beyond its idyllic historic city center, cookie-cutter subdivisions are eating away at farm fields, ranches and forests. According to the ...

  • Impact of IT on river modeling

    Background Models of river channels and river flows have been used to good effect for many years. HR Wallingford Group, in the UK, has been building physical models of rivers for nearly 60 years. Some years ago, it was predicted that physical modeling would soon cease to exist, to be entirely replaced by computer models. This has not happened - in fact, the demand for physical models is greater ...
