  • Stormwater Best Management Practices (BMP)

    Storm water is the result of rain or snow melt that collects in an area that can drain from into a nearby body of waters such as a lake or river. The water can collect on roof tops, parking lots, saturated ground, roads, etc. The problem is that many of the pollutants of our modern living such as oil, grease, pesticides, sediment, salt, and animal waste are washed away within the storm water and ...

  • Monitoring fuels in Stormwater - Case study

    The Situation A major pipeline company has large storage tank farms throughout the Western States. The pipeline company transports, stores, blends additives, and distributes gasoline, diesel, and jet fuel to retail service stations and airports. Due to the quantity and movement of fuel at these facilities, there is always the potential for fuel spills. These facilities prevent out of ...

  • 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 ...

  • An Investigation into the Water Quality of the Charleston Peninsula Storm Drains

    Since the late 1980’s, the South Carolina Department of Health and Environmental Control (SCDHEC) has expressed concern over extremely high fecal coliform counts found in several of the many storm drains that discharge from peninsular Charleston (City of Charleston, 1998). Although the City of Charleston is responsible for the fifty-plus storm drains, Charleston Water System wants to determine if ...

  • Alternatives for Finding Illicit Discharges to Stormwater Systems

    ABSTRACT Provisions of the National Pollutant Discharge Elimination System (NPDES) permits for stormwater discharges require that permits for municipal separate storm sewers systems (MS4s) shall include a requirement to effectively prohibit problematic non-storm water discharges into storm sewers. Emphasis is placed on the elimination of inappropriateconnections to urban storm drains. ...

  • 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 ...

  • Stormwater and Spill Management at an Iron Pipe Foundry in Texas

    ABSTRACTLarge industrial sites have had permits for storm water discharges under the NPDES program of the Clean Water Act since the mid to late 80’s. Recent emphasis has been placed on regulated facilities to prepare and implement Spill Prevention, Control and Countermeasure (SPCC) plans under the Oil Pollution Prevention Act (40 CFR 112). A large iron pipe foundry in Texas has several storm ...

  • Catchment `greening` using stormwater in Adelaide, South Australia

    ABSTRACTThe paper reviews the goals of stormwater management adopted in Adelaide and declares a focus on harvesting of stormwater to replace mains water in irrigating areas landscaped with grass, flower beds and shrubs. Four categories of catchments are recognised according to their levels of pollution production - roof runoff and 'low', 'medium' and 'high' pollution runoff surfaces. Four case ...

  • 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 ...
