  • 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 ...

  • ORC Reduces Benzene to Below Site Goals – The Netherlands

    Site Summary The former gasworks is located in the city of Enkhuizen residing in The Netherlands. Shortly after site activities ceased, the land was redeveloped. A site assessment indicated that the soil beneath a former cellar was contaminated with benzene. The depth of the contamination was estimated at 6 m-bgs (~20 ft), but couldn’t be assessed further due to restrictions caused by debris in ...

  • What is so hard about drainage modeling?

    Drainage modeling often suffers from the misconception that it is simple, but while it appears obvious that rain water will flow to the lowest point, the physical processes involved are not always well-understood or predictable. Drainage models attempt to predict that part of the water cycle that involves rainfall and its consequences, including potential flooding. Although flooding is, at its ...

  • Using the Clean Development Mechanism to mitigate emissions from peatlands: “Avoided drainage” and “Rewetting” as new CDM activities

    Introduction Currently, the only land-use, land-use change and forestry (LULUCF) activities that are eligible under the Clean Development Mechanism (CDM) are afforestation and reforestation (A/R), which allow for the generation of credits by net removal by sinks. This could include afforestation and reforestation of wet organic soils (peatlands), e.g. with peatswamp forest tree ...

  • Excavator height measurement, protects power supplies, protects drivers

    In a change from their more usual applications controlling and measuring flow and level of all sorts of materials, Pulsar Process Measurement Ltd have supplied non-contacting ultrasonic level measurement to the North Level District Internal Drainage Board to measure the height of the arm of the jib arms mounted on hydraulic excavators used to keep the drainage channels clear. As the ...

  • Nitrate removal using different carbon substrates in a laboratory model

    Agricultural fields have been frequently identified as major contributors of nitrate leaching into surface and ground waters. Tile drains can act as direct pathways, transferring leached nitrate to surface water. Bioreactor filters are useful for the removal of nitrate from drainage waters; however, these filters require an external carbon supply to sustain denitrification. In this study, four ...

  • Bioremediation of diesel spill - cumbria, united kingdom

    Introduction Microbac has successful undertaken the clean up of a diesel spill at a site in Cumbria. The oil escaped from a large storage tank, located at the top of an incline after a problem occurred with closure of the valve. The position of the spill resulted in oil running down the incline and into the site drainage system. In response to the client"s request, Microbac ...

  • Phosphorus retention in riparian buffers: review of their efficiency

    Received for publication February 15, 2008. Ground water and surface water interactions are of fundamental importance for the biogeochemical processes governing phosphorus (P) dynamics in riparian buffers. The four most important conceptual hydrological pathways for P losses from and P retention in riparian buffers are reviewed in this paper: (i) The diffuse flow path with ground water flow ...

  • Developing optimum solutions to flooding

    Developing optimum solutions to flooding With a very long period of wet weather in the summer overlaid by intense rainfall, 2007 was the wettest summer in the UK on record. This unusual weather pattern resulted in very high localised runoff, with three events in England exceeding the 1 in 100 year return period over that time – some of the worst flooding that has ever occurred in ...

  • Dogs put trust in onsite sewage treatment

    One of the obvious challenges of running Dogs Trust rehoming centres is the need to dispose of a significant quantity of hazardous waste. All locations not connected to mains drainage have to be served by reliable on site treatment systems and on completion of the latest installation at Salisbury a total of five WPL systems will be in operation around the UK. The charity cares for some 16,000 ...
