  • Stormwater

    Stormwater is a term used to describe water that originates during precipitation events. It may also be used to apply to water that originates with snowmelt or runoff water from overwatering that enters the stormwater system. Stormwater that does not soak into the ...

  • Capturing the Potential of Stormwater

    Management of the urban water cycle in Australia has changed significantly over the past few decades. Stormwater management philosophy has evolved from the conventional, but still important, flood mitigation paradigm, to the current runoff quality control approach. It is now progressing towards the harvesting and reuse concept whilst retaining the previous two targets. iven the current interest ...

  • Stormwater Management for Urban Environments

    IntroductionElmhurst College, a hundred-thirty-five year old private learning institution, is proceeding with a campus redevelopment project that will include a one hundred seventy bed residence hall. In addition, the college continues to be a role model for sustainable site design and an educational resource for both students and the community.The need for additional housing, due to ...

  • The urban stormwater farm

    Currently more than 3 billion people live in urban areas. The urban population is predicted to increase by a further 3 billion by 2,050. Rising oil prices, unreliable rainfall and natural disasters have all contributed to a rise in global food prices. Food security is becoming an increasingly important issue for many nations. There is also a growing awareness of both ‘food miles’ and ‘virtual ...

  • Stormwater: Questions and Answers

    The whole subject of Stormwater is complicated. Here's a chance for you to check out some of the most frequently asked questions about stormwater . . . and their answers. What is an NPDES (National Pollutant Discharge Elimination System) permit? The Clean Water Act prohibits anybody from discharging 'pollutants' through a 'point source' into a 'water of the United States' unless they ...

  • 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 ...

  • Stormwater availability in the Gaza Strip, Palestine

    Stormwater harvesting has become an important water resource. The rational runoff formula has been applied using GIS as a tool to estimate runoff amounts from different landuse categories. These amounts have been estimated to be 37 Mm? in the existing landuse and will reach 43 Mm? for planned landuse, i.e. urban development expansion. Continuous urbanisation will result in more wastage of ...

  • Stormwater treatment area 3/4

    Restore the Everglades That's the task the Florida Legislature set for the South Florida Water Management District. But how? Decades of development had eliminated the sheet flow of water from Lake Okeechobee. Densely populated cities and a 700,000-acre agricultural area, drained by 1,500 miles of canals and levees, now lay between the lake and the Everglades. Wetlands have disappeared. ...

  • 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 ...

  • Maintenance of a Rainstore3 Stormwater Storage Chamber

    Invisible Structures, Inc. recommends that stormwater be pretreated prior to discharging into the chambers to avoid foreign matter accumlation inside the chamber. This can be accomplished by a variety of techniques or products. Some examples are: Short Term Storage (Detention Basin) “Zero” maintenance – the Preferred Method: Use a ...

  • Stormwater Solids Reduction for NPDES Permits

    Finally obtaining a National Pollution Discharge Elimination System (NPDES) Permit is often a relief but is by far not the end of the story. Meeting the requirements of that permit often proves to be quite difficult and stiff fines are freely doled out to those who fail to meet regulatory limits. For one Midwest jet propulsion manufacturing facility, the issue of total daily solids discharge ...

  • Shoreline erosion and stormwater management project case study

    In early August, 2007, a homeowner on Lake Waubesa near Madison, Wisconsin contacted Agrecol Corporation about their Envirolok Vegetated Retaining Wall System. The homeowner wanted to replace a failing lake wall with an environmentally-friendly shoreline. The old wall was built with creosote railroad ties which was just one of many stormwater management problems with the project site. A ...

  • Preliminary stabilisation of stormwater biofilters and loss of filter material

    Stabilisation affects performance of stormwater biofilters operating under intermittent wetting and drying, mainly due to wash-off of filter material. Understanding the dynamics of solids wash-off is crucial in designing stormwater biofilters. The current study analysed the dynamics of solids wash-off in stormwater biofilters and quantified the loss of solids from the filter. Four Perspex™ ...

  • The 7 Tips for Highly Effective Stormwater Management By-Laws

    ABSTRACT The Stormwater Phase II Final Rule, which applies to small municipal separate storm sewer systems (MS4s) in “urbanized areas”, requires communities across the country to adopt local legislation that will control the harmful effects of stormwater runoff and prohibit non-stormwater pollution from entering the drainage system. Adopting a thoughtful and comprehensive stormwater by-law ...

  • Improving sediment removal in standard stormwater sumps

    Standard sumps are an important component of our stormwater drainage system. Recently they have received significant attention as a stormwater pre-treatment device to remove sediment from stormwater runoff. The objective of this research is to explore some simple structures to be installed inside standard sumps to improve sediment removal efficiency. A number of structures were tested and two ...

  • Model-based monitoring of stormwater runoff quality

    Monitoring of micropollutants (MP) in stormwater is essential to evaluate the impacts of stormwater on the receiving aquatic environment. The aim of this study was to investigate how different strategies for monitoring of stormwater quality (combining a model with field sampling) affect the information obtained about MP discharged from the monitored system. A dynamic stormwater quality model was ...

  • Exploring fecal indicator bacteria in a constructed stormwater wetland

    Microbial pollution in surface waters is a concern throughout the world, with both public health and economic implications. One contributing source to such pollution is stormwater runoff, often treated using various types of stormwater control measures. However, relatively little is known regarding microbe sequestration in constructed stormwater wetlands (CSWs), one type of commonly installed ...

  • 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 ...

  • 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 ...
