  • 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 ...

  • 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 ...

  • Washington State DOE stormwater report - Case Study

    Fitesa, a non-wovens manufacturer in the state of Washington consistently tests stormwater but experienced problems meeting the stormwater standards for zinc and copper discharge. Zinc is used in galvanized metal, shingles, finishes in paints, and car tires—zinc iseverywhere. Copper is used in items such as in brake linings and pressure treated lumber. At sites near heavily traveled roads, ...

  • 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 ...

  • 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 ...

  • Retrofitting an Existing Stormwater System to Meet Numerical Effluent Limits - Stormwater Management at Seattle-Tacoma International Airport

    ABSTRACTOwned and operated by the Port of Seattle, Seattle-Tacoma International Airport (STIA) is the 28th busiest airport in the world. A Section 401 Water Quality Certification was issued to the Port to allow its expansion projects to proceed. This certification required existing portions of the airport be retrofitted to meet current stormwater standards. In addition, the Port’s renewed NPDES ...

  • 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 ...

  • 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 ...


  • The world`s largest stormwater alum treatment facility - in Florida

    Stormwater in the Florida canal system is slow moving.  The green, murky water in the lakes fed by the Apopka-Beauclair canal is caused by an overabundance of algae-feeding compounds, mainly phosphorus, resulting in chronic algal blooms.  The Nutrient Reduction Facility (NuRF) project designed a system to inject aluminum sulface (alum) into the nutrient-laden water in direct proportion ...

  • 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 ...
