  • 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 ...

  • Effects of integrated stormwater management strategies on the combined sewer system and the wastewater treatment plant-river system

    ABSTRACTThis is an investigation into possible changes to quantity and composition of sewage in the combined sewer system and the waste water treatment plant (WWTP) caused by new stormwater management strategies (mainly by disconnecting areas from the sewer system). Various scenarios were developed and the consequences on the water systems were calculated by using the simulation model KOSMO, in ...

  • Measuring the Effectiveness of Watershed-Based General Stormwater Permitting

    ABSTRACTThe U.S. EPA and most water resources professionals advocate holistic and adaptive watershed management approaches to the protection and restoration of aquatic ecosystems by encouraging pollution control strategies that are developed through collaborative partnerships within a hydrologic boundary. This paper evaluates the effectiveness of the holistic adaptive management approach through ...

  • Enlightenment from ancient Chinese urban and rural stormwater management practices

    Hundreds of years ago, the ancient Chinese implemented several outstanding projects to cope with the changing climate and violent floods. Some of these projects are still in use today. These projects evolved from the experience and knowledge accumulated through the long coexistence of people with nature. The concepts behind these ancient stormwater management practices, such as low-impact ...

  • Developing a Stormwater Infrastructure Geospatial Database for a Large Non-Traditional MS4 System

     ABSTRACT The Massachusetts Department of Conservation and Recreation (DCR) is a state agency which owns and maintains parks, conservation and watershed land, and roadways. They are regulated as a non-traditional MS4 stormwater municipality under the U.S. Environmental Protection Agency’s (EPA) National Pollutant Discharge Elimination System (NPDES) Phase II program. To satisfy the ...

  • Elimination and accumulation of polycyclic aromatic hydrocarbons in urban stormwater wet detention ponds

    The concentrations of polycyclic aromatic hydrocarbons (PAHs) in water and sediments of seven wet detention ponds receiving urban stormwater were investigated. The ponds comprised traditional wet detention ponds with a permanent wet volume and a storage volume as well as ponds that were expanded with sand filters and other means to improve the removal of micropollutants. The concentrations of ...

  • Restoration of stormwater retention capacity at the allotment-scale through a novel economic instrument

    Urbanisation results in changes to runoff behaviour which, if not addressed, inevitably degrade receiving waters. To date, most stormwater management has focussed on the streetscape and public open space. Given that much of the catchment imperviousness is located on private land, we developed and tested a novel economic instrument (a uniform price auction) for encouraging allotment-scale ...

  • Real-Time Stormwater Management Using Depth, Duration, Frequency Thresholds

    ABSTRACTThe City of Austin (City) operates a Flood Early Warning System (FEWS) to reduce public exposure to flash flood hazards. The system is operated and maintained by the Watershed Protection and Development Review Department, Watershed Engineering Division. Advanced information and warning of urban storm water flooding is achieved by the FEWS. A critical component of the system is rainfall ...

  • 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 ...

  • Integrated urban water management in commercial buildings

    Monitoring results are presented as an annual water balance from the pioneering Landcare Research green building containing commercial laboratory and office space. The building makes use of harvested roof runoff to flush toilets and urinals and irrigate glasshouse experiments, reducing the demand for city-supplied water and stormwater runoff. Stormwater treatment devices also manage the runoff ...

  • Integration of Watershed Planning and Wellhead Protection Programs

    For communities using groundwater as the primary source of water supply, delineating, managing, and protecting the wellhead recharge area is essential to assuring a sustainable water resource system. Because many communities are also required to obtain a National Pollutant Discharge Elimination System (NPDES) permit for discharges from municipal separate storm sewer systems (MS4s), delineating ...

  • Wallingford solutions enable an integrated approach to modeling

    Of the many advantages to Wallingford Software’s InfoWorks suite of solutions, one that is particularly valued in today’s demanding modeling environment is their reputation as the gold standard for integration. The solutions allow one interface to answer a wide range of questions, rather than requiring a user to laboriously work through a range of modules or packages. Such key but separate ...

  • Integrated conceptual modelling of faecal contamination in an urban estuary catchment

    Urban stormwater is regarded as a key input of faecal contamination in receiving water bodies and therefore, a major concern for health risks associated with aquatic recreation. Wastewater leakages, cross connections and overflows, together with faeces washed from surfaces during rainfall events, are possible origins of faecal contamination which enter these water bodies through stormwater ...

  • Integrated Site Closure Achieves Business and Regulatory Goals

    A new concept for cleanup of contaminated properties and hazardous waste sites applicable under federal and state regulatory programs is helping clients achieve both business and regulatory goals at their sites. The concept, called 'Integrated Site Closure', is the seamless integration and delivery of services necessary to reach regulatory closure of contaminated properties. Regulatory closure ...

  • Integrated Environmental Risk Management in Real Estate Transactions

     Traditional risk management posits a rational, five-step process for managing risks. The outstanding differences between this traditional process and the environmental risk management process lie in the technicality and complexity of step one (identifying and analyzing environmental risk) and of the first part of step two (examining the feasibility of  alternative risk management, ...

  • Compost integral in new website in building soil

    A website called “BuildingSoil” has been launched by the Washington Organic Recycling Council to help builders preserve healthy soil on building sites. It's the latest Soils for Salmon project which aims to change standard site development practices. These new “soil best management practices” will soon be required by local governments around western Washington, as they update local codes to ...

  • Permeable (pervious) pavements and geothermal heat pumps: addressing sustainable urban stormwater management and renewable energy

    Water and energy are the two most fundamental ingredients of modern civilisation and are also the most precious and essential resources around the globe. They are inseparably coupled and with increasing pressures on these resources as the world's populations grow, the concepts of a combined approach can be applied while addressing the economic, climate, water and energy crises. Sustainable ...

  • A flexible modelling environment for integrated urban water harvesting and re-use

    The steady increase of urban population and the possible effects of climate change that may adversely affect the amount of water available in current water supply systems, makes the study of stormwater and rainwater harvesting and wastewater recycling a high priority. The basic proposition is that any system of water supply that can reduce the amount of water drawn from main reservoirs will be of ...
