  • Best management practices (BMPS) for discharging water from a construction site

    Having problems on your job site with regulations related to pumping water from your site? Discharge water may carry harmful compounds that can, and have affected our water quality and the ecosystem, hence the environmental agencies concerns. When pumping from dewatering systems, storm water management ponds (SWMPs), excavations or trenches, or any form of surface runoff, BMPs are needed to ...

  • Dutch Dewatering, a Dry Construction Site Revenue Model

    It was the spring of 2010 - during the establishment phase of BBA Pumps Inc. At the time, I went to visit several construction sites in the Netherlands to see how successful dewatering was being organized. Talk about a small country showing how great it can be! It was an absolutely eye-opening experience. The Netherlands is one of the most densely populated countries ...

  • Simple Separation: Diverting Wood And Cardboard at Construction Sites

    Diverting Wood And Cardboard At Construction Sites Residential home construction in Wisconsin generates 128,000 tons of residuals annually, according to a 1998 study by Camp, Dresser & McKee. Ten builders are participating in a project to demonstrate how easily major components of this waste stream can be recycled. The Metropolitan Builders Association (MBA) of Greater Milwaukee, the ...

  • Integrated Constructed Wetlands: concept, design, site evaluation and performance

    'Integrated Constructed Wetlands' (ICW) are a joined-up approach to land and water management. Significant synergies were achieved by explicitly combining environmental, ecological and aesthetic objectives. Intercepted precipitation was found to be the main factor determining treatment efficacy. Soil infiltration and evapo-transpiration combined to enhance hydraulic residence time. A wetland area ...

    A large scale water treatment system rental to Birse Construction as part of the enabling works for site redevelopment.Each separator/settling tank was equipped with a duty and standby pump.The size of activated carbon vessel is unique within the UK with a flow capacity of 200 m3/hr. The vessel contains 20 tonnes of activated carbon and GRS can mobilise several of these at short notice, thus ...


  • Performance characterisation of a constructed Wetland

    Performance of a constructed wetland is commonly reported as being variable due to the site specific nature of influential factors. This paper discusses the outcomes from an in-depth study which characterised the treatment performance of a wetland based on the variation in the runoff regime. The study included a comprehensive field monitoring of a well-established constructed wetland in Gold ...

  • Geotextiles in Construction Dewatering

    Woven geotextiles work wonders in dewatering applications as wraps around well screens and sump pit screens. The textile can be sewn into sleeves or tubes to be slid over the well screen or sump pit framework. This technique allows the user to compensate for well screens with slots that are too large or for sump pit piping with large perforations. By adding the geotextile sleeves the user ...

  • Dams Construction Tenders???

    “The idea is to create a central place that is enormously more efficient than what we have today and bring down the cost of infrastructure by making it smarter,” he says. “It’s a huge deal in the developing world, and even in our country, the infrastructure is crumbling. It’s estimated that $2-3 trillion is needed to upgrade our infrastructure.” Oliver says 85 ...

  • On-site treatment of domestic wastewater using a small-scale horizontal subsurface flow constructed wetland

    A small-scale horizontal subsurface flow constructed wetland, located in North Greece, was designed and constructed to treat wastewater from a single-family residence. A three-year monitoring program was undertaken to evaluate the performance of this system. The monitoring campaigns were organized every 7 days. Water quality samples were collected at the inlet, at intermediate points (i.e. at the ...

  • Designing a constructed wetland for the detention of agricultural runoff for water quality improvement

    Received for publication December 18, 2008. The goal of this study was to construct a wetland that would detain runoff from a 162-ha watershed for the purposes of improving water quality. The volume of runoff that needed to be detained was determined to be that amount coming off the 162-ha watershed consisting of 146 ha of cultivated crop land and 16 ha of pasture that exceeded the amount that ...

  • How to Deal with Oils When Treating Contaminated Construction Dewatering Water

    Oils are defined as organic materials that are not completely dissolved in water and present in the forms of sheens, globules, droplets. If present at a construction dewatering site, oil will most likely need to be removed from the contaminate water before discharge in order to meet the discharge limits for oil & grease (O&G) and/orspecific contaminants of concern (COC) that oil may carry ...

  • The role of constructed wetlands for biomass production within the water-soil-waste nexus

    The use of constructed wetlands for water pollution control has a long standing tradition in urban, peri-urban, rural, agricultural and mining environments. The capacity of wetland plants to take up nutrients and to filter organic matter has been widely discussed and presented in diverse fora and published in hundreds of articles. In an ever increasingly complex global world, constructed ...

  • Dredging Technology – Underwater Excavation and Construction

    The presence of water is ussualy considered a nuisance in construction, particularly when excavating removing water is common practice. In some cases however, water can be a very useful tool that may simplify things greatly. With the “flooded excavation principle”, the construction site is flooded after the retaining walls have been installed (e.g. sheet pile). When the ...

  • Water resource management with a combination of underground dam/qanat and site selection of suitable sites using GIS

    Subsurface dams and aqueducts have been used for many years as important sources of water in different parts of the world. Nowadays, little attention is paid to aqueducts. On the other hand, there is a great tendency for constructing and using subsurface dams in many arid and semiarid parts of the world such as Iran. A combination of these two structures was established in ancient Iran including ...
