  • 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 ...

  • 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, ...

  • 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, ...

  • Blue Heron Ultraviolet Stormwater Management System case study

    Horry County Engineering Department Myrtle Beach, South Carolina, USA Even a single day of beach closure has a major impact on the tourist-dependent economy of beach communities. To reduce beach closures in Myrtle Beach, HDR used ultraviolet (UV) light to treat stormwater runoff to reduce pathogens prior to discharge to the ocean. The system uses disinfection ...


  • Characterization of the potential impact of retention tank emptying on wastewater primary treatment: a new element for CSO management

    Theoretical studies have shown that discharges from retention tanks could have a negative impact on the WWTP's (Wastewater Treatment Plant) effluent. Characterization of such discharges is necessary to better understand these impacts. This study aims at: (1) characterizing water quality during emptying of a tank; and (2) characterizing the temporal variation of settling velocities of the waters ...

  • GE Leakwise Application Notes: Leak Detection for a Floating Roof Oil Storage Tank

    Oil Storage Tank with a Floating Roof Floating Roof Drainage Operation Stormwater accumulated on a concave floating roof of an oil storage tank may affect its floatation, making it necessary to immediately drain the water. This is usually done through a flexible pipe, running from the floating roof down the tank, with an outlet above the ground near the bottom of the tank. ...

  • A technical guide to complying with Federal SPCC Regulations

    Let’s start by clarifying what SPCC is not since SPCC does overlap other Federal and State environmental regulations. SPCC is not: NPDES – Permits under NPDES, such as stormwater or water discharge permits, are required to discharge pollutants into the “navigable waters of United States.” While it is never permitted to discharge “oil” into any waters of the US, there is some overlap with NPDES in ...

  • Seatac airport third runaway

    Active Treatment with 1% ChitoVan™ Chitosan Acetate The west side of Sea-Tac airport was widened by adding 11 million cubic yards of fill dirt to create the 3rd runway. Because the west side of the airport drains to Miller Creek, a protected NW stream, all of the construction stormwater had to be captured and treated prior to discharge. During the project over 5 billion gallons of ...

  • The semi-sewer river: hydraulic backwater effects and combined sewer overflow reverse flows in Central Brussels reduce deoxygenation impact further downstream

    In 2011 and 2012 the dissolved oxygen content in the low-discharge river Zenne was monitored continuously, every 5 minutes, downstream of Brussels city centre, making it possible to document the complex mechanisms by which combined sewer overflow (CSO) spills affect both the hydraulics and the oxygen balance of the hydrosystem. In addition to oxygen demand impacts, proportions of water volumes ...

  • Model 8 oil grabber® removes small amounts of oil from plant drain water

    Problem: Worldwide, Reichhold Chemical Corp. produces some 5600 products. At St. Helens, Ore., they produce three -urea, ammonium nitrate and ammonia. Plant drain water is discharged into the Columbia River, and although oily residues are minuscule because of a concerted program to keep oil off the floors, some is present - drippage from ammonia compressors, vehicles and machine maintenance ...

  • Erosion and Sediment Control: Navigating NPDES Regulations, the SWPPP, and Techniques for Compliance

    Erosion and Sedimentation: Why Are They a Problem? The US Environmental Protection Agency lists sediment as the single most common pollutant in rivers, streams, lakes, and reservoirs. With all the potentially harmful chemicals and substances in the world, it seems odd to many people that sediment—dirt, essentially—is singled out as the major culprit. Yet these particles of ...

  • GE Leakwise Application Notes: Oil Sheen Detection -- An Alternative to On-Line PPM Analyzers

    Introduction Discharge of hydrocarbons in industrial water is restricted by environmental authorities in most countries to a few parts per million (ppm). Environmental authorities currently monitor wastewater, stormwater, and cooling water discharges from ...

  • Case study - Dubai labor camp not worried about water

    Installer: Jallad Environmental Distributor: Clearbrook, Inc. With water scarcity as a major concern for the MENA region, the need to reuse wastewater became a major focus for a project located in the labors camp region of Dubai. Consisting of a fluctuating occupancy (between 4,000 to 6,000 workers throughout the year), a decentralized wastewater system was determined to be the best course of ...

  • Using a Self Bailer on Containment Sumps to Filter Hydrocarbons

    How do you eliminate problems associated with the collection of rainwater in outdoor containment systems and maintain compliance with EPA and Clean Water Act regulations?  Since most outdoor oil storage tank sumps and oil drum spill pallets will inevitably be exposed to local precipitation and storm water runoff from nearby catchment surfaces, it is necessary to make sure you ...
