  • Investigations into and optimisation of the performance of sewage detention tanks during storm rainfall events

    ABSTRACTCombined Sewage Detention Tanks (CSDT) are components of combined sewage systems commonly used in Germany. A lack of knowledge of the processes occurring within these structures causes the engineer to apply conceptual approaches in the simulation of pollutant transport. The investigations presented were implemented in an integrated systematic way. Extensive analytical, experimental and ...

    Global was contracted by a local Road Commission site. The Road Commission site serves as the county level road agency, which maintains more than 1,813 miles of roads and streets and over 250 signalized intersections. The Road Commission contains six sites across the county. Each site is responsible for its particular area. The sites all include maintenance garages, diesel and gasoline ...

  • SURE HOUSE: Students Design Storm-Ready Shore Home

    Every other year, collegiate teams from across the country partake in the U.S. Department of Energy’s Solar Decathlon with the challenge of designing a fully solar-powered home that fuses style, efficiency and affordability. For more than 30 students at Stevens Institute of Technology in Hoboken, New Jersey, though, those requirements were just a starting point. Entering the national ...

  • Implementing SPCC Requirements and Storm Water BMPS at a Large Industrial Facility

    ABSTRACTRecently, much attention has been focused on storm water pollution prevention and spill management. The U.S. Environmental Protection Agency (EPA) issued its Final Rule for Oil Pollution Prevention (40 CFR Part 112) on July 17, 2002, making major changes to the original rule issued in 1973. Facilities subject to this regulation must amend their Spill Prevention, Control, and ...

  • Maintenance for septic tanks

    Septic tanks are widely used for on site sewage treatment for domestic homes which are not connected to the sewer system. Little attention is given to the septic tank until there are problems such as smells or poor drainage or ponding on the surface. A little maintenance of the septic tank can be very helpful in maintaining performance of the septic tank. The outflow from a septic tank percolates ...

  • KLa Jet Aerators/Mixers for Large Diameter Equalization Tanks - Case Study

    Flow Equalization Many municipalities are facing the challenge of having to equalize large volumes of storm water sometimes mixed with raw sewage in order to continuously meet their permit limitations. The equalized flow is stored during a storm event and then slowly diverted to the treatment facility when influent flows return to normal levels.  In the past few years the need ...

  • Enhancement of settling tank capacity using a new type of tube settler

    The effectiveness of a newly developed lamellar settler was confirmed by onsite experiments. The device had inclined parallel plates arranged in a vertical direction in a settling tank. This vertical arrangement method enables many more plates to be set compared to the conventional horizontal arrangement. As an original and distinctive innovation, both the right and left edges of the plates were ...

  • Measurement of flow velocity profiles in tank structures using the prototype device OCM Pro LR

    Generally, studies investigating the treatment efficiency of tank structures for storm water or waste water treatment observe pollutant flows in connection with conditions of hydraulic loading. Further investigations evaluate internal processes in tank structures using computational fluid dynamic (CFD) modelling or lab scale tests. As flow paths inside of tank structures have a considerable ...

  • Safe Drain® Saves My Facility From Accidental Spill

    "I am writing to thank-you for a great product. This morning we had a 25 gallon diesel spill near our Vehicle Service Area. The spill was a fluke - from the tank of a truck that was parked on a gradient - left without a gas cap. Diesel poured out of the truck onto the asphalt - directly into a newly installed Spill Safe Drain that was closed tightly. All of the spilled product was recovered, ...

  • Flow characteristics of individual lot stormwater detention

    In this paper the flow characteristics of stormwater are analyzed as it travels from a roof gutter down-pipe and the turbulent flow generated on entering an individual lot on-site stormwater detention (OSD) unit beneath a residential carport. Comparison was made between a full-scale model and computational fluid dynamic (CFD) simulations to determine the flow characteristics. These modular ...

  • Soakaway Crates

    The Environment Agency has stated that you cannot use soakaway crates for septic tank and sewage treatment plant soakaways. They are not listed as a suitable sytem in either the Building Regulations or the BS6797 2007 and as such, cannot be used. They are for rainwater and storm water only For more information and reasons why they cannot be used for ...

  • Erosion resistance and behaviour of highly organic in-sewer sediment

    Reliable prediction of time-varying pollutant loads in combined sewer systems during storm periods can aid better management of the release of pollution into natural environments as well as enhancing storage tank design. Better understanding of the behaviour of sewer sediments is crucial for the development of models that adequately describe the transport of in-sewer solids and accurately ...

  • An integrated approach to water management in Kayseri: rainwater collection and use in an amusement park

    Water management in urban areas of developing countries is a major environmental challenge for the future. Within the framework of the IWA Cities of the Future Programme, current water and wastewater management systems are investigated in Kayseri, Turkey, with the purpose of bringing water into the center of city life by a reformed pilot project. In order to assess both the quantity and dynamics ...

  • Innovative use of lamella clarifiers for central stormwater treatment in separate sewer systems

    Lamella settlers have been used in the past few years for the sedimentation of particles in wastewater and stormwater applications. A new and very innovative approach for the treatment of stormwater flows is proposed which extends the portfolio of solutions beyond traditional settling tanks. Surface runoff is stored in a sewer or a basin and finally treated in a small but continuously operated ...

  • Proactive Leak Detection of Oil & Gas Assets Can Improve Worker Safety

    According to the U.S. Energy Information Administration, there have only been 4 new refineries built in the last 20 years on US soil. Those 4 refineries have a combined capacity of These complex, engineering amusement parks must be properly maintained if they want to continue to not only be operable but also profitable. One aspect of proper maintenance and environmental stewardship is ...

  • How do you clean a stormwater management pond?

    How do you clean a stormwater management pond (SMWP) without draining the pond first? A clean-out of the SWMP is required once every 5-15 years to remove accumulated sediments to ensure the pond continues to function as intended. Drainage of the SWMP is not always required to facilitate the clean-out. By combining the pumping and excavation into one process! New pumping technology - Dragflow ...

  • Characterization of phosphorus sources in rural watersheds

    Received for publication February 21, 2008. Correct identification of P sources in rural watersheds is critical for the development of cost-effective measures to combat agriculturally-driven eutrophication. The chemical composition of various storm runoff types (field surface runoff, field drain outfalls, roads, farmyards, and septic tanks) and the receiving streams in three micro (<10 km2) ...

  • 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 ...
