  • 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 ...

  • Productivity Gains in Stormwater Design

    For some engineering consultants, traditional stormwater pond design can be one of the most frequent projects within their services portfolio. An engineer with prior experience can size and produce plans with assistance from modeling software, AutoCAD, and supporting tools with relative ease. But even very routine projects can benefit from modeling software improvements. McBade Engineers and ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Taking advantage of stormwater, a plentiful, free resource

    As the saying goes, when it rains, it pours. Rain and snow and other types of precipitation are a resource more organizations would be wise to take advantage of as water scarcity increases around the globe. Stormwater, precipitation that isn’t absorbed into the ground, is a freely available resource, but is there enough of it to make a difference? The amount of runoff varies from storm ...

  • Synergistic benefits between stormwater management measures and a new pricing system for stormwater in the City of Hamburg

    Hamburg is a growing metropolitan city. The increase in sealed surfaces of about 0.36% per year and the subsequent increased runoff impacts on the city's wastewater infrastructure. Further potential risks to the drainage infrastructure arise also from effects of climate change, e.g. increased intensity and frequency of heavy rainfalls. These challenges were addressed in the Rain InfraStructure ...

    Untitled Document When the Environmental Protection Agency (EPA) threatened to put shipyards in the Coos Bay Estuary on the National Priorities List of hazardous waste sites, the Charleston ...


  • Municipal Stormwater Program Audits in California: Findings and Lessons Learned

    ABSTRACT EPA, with the assistance of Tetra Tech and the California Regional Water Quality Control Boards, has conducted 122 on-site audits of municipal stormwater programs over past six years to assess NPDES permit compliance and program effectiveness. Evaluations consisted of a programmatic review of individual MS4s and an in-field verification of these program elements. The project goals ...

  • Low impact development: San Francisco’s green approach to stormwater management

    This paper presents the methods, findings, and policy implications of a comprehensive evaluation of low impact development (LID) techniques for the City of San Francisco. LID is an innovative approach to stormwater management that relies on decentralized, small-scale stormwater facilities and site-design techniques to reduce wet weather flows and to remove stormwater pollutants. The LID analysis ...

  • Shoreline property upgrade saved by Lightweight stormwater solution case study

    Renovating a residential property may be commonplace, however upgrades adjacent to the sensitive Bayou Texar estuary in Pensacola, FL, is a bit more difficult. The estuary is an ecologically sensitive area protected by the Florida Department of Environmental Protection. The consulting engineer and contractor had a problem; with limited space, how do they keep stormwater on site with the addition ...

  • New option for stormwater treatment maximizes usable land area for redevelopment

    Untitled Document In June 2002, First Independent Bank of Vancouver, Wash., began construction on its 15,000 square-foot First Investments Plaza office complex. The ...


  • New strategies in stormwater-meltwater management in the city of Bergen, Norway

    ABSTRACTIn the City of Bergen, Norway, extensive measures against point pollution sources are now to be implemented and to be finished before the end of year 2000, improving the receiving water conditions. Local politicians and public opinion support high standards of receiving water, even higher than the national level. Future improvements in the receiving water quality is planned through ...
