  • 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 ...

  • What is stormwater?

    Stormwater runoff, water that isn’t absorbed into the ground after a weather event, is a potential water source that cities across the world have struggled with for decades. Why is coping with it such a challenge? Whether the precipitation is water or ice, its addition to the environment can be a problem, especially when a lot of it falls in a short amount of time. When this occurs in ...

  • Controlling urban stormwater pollution by constructed wetlands: a Canadian perspective

    During the past 20 years, Constructed Stormwater Wetlands (CSWWs) have attained broad acceptance in Canada as effective measures for stormwater management. CSWWs are used mainly for improving stormwater quality by providing sufficient treatment volumes in shallow permanent pools. This leads to high requirements for land, which is one of the constraints on CSWWs use. Even though CSWWs perform less ...

  • Can urban tree roots improve infiltration for stormwater management?

    Global land use patterns and increasing pressures on water resources demand creative urban stormwater management. Strategies encouraging infiltration can enhance groundwater recharge and water quality. Urban subsoils are often relatively impermeable, and the construction of many stormwater detention best management practices (D-BMPs) exacerbates this condition. Root paths can act as conduits for ...

  • Urban waste- and stormwater management in Greece: past, present and future

    Urban wastewater and storm management has a long history which coincides with the appearance of the first organized human settlements (ca. 3500 BC). It began in prehistoric Crete during the Early Bronze Age (ca. 3200 BC) when many remarkable developments occurred in several stages known as Minoan civilization. One of its salient characteristics was the architecture and ...

  • Banner Bank Building – A Leader in Urban Stormwater and Graywater Reuse

    Urban stormwater runoff poses unique challenges to city planners, civil engineers and property owners. As designers seek better strategies to protect watersheds from contaminated urban runoff they are also faced with pressure to reduce costs while increasing capacity. Sustainable design strategies are proving that urban stormwater rates and quantities can be reduced while improving water quality. ...

  • Characterization and source identification of stormwater runoff in tropical urban catchments

    The characteristics of urban stormwater pollution in the tropics are still poorly understood. This issue is crucial to the tropical environment because its rainfall and runoff generation processes are so different from temperate regions. In this regard, a stormwater monitoring program was carried out at three urban catchments (e.g. residential, commercial and industrial) in the southern part of ...

  • The development of a novel approach for assessment of the first flush in urban stormwater discharges

    The management of stormwater pollution has placed particular emphasis on the first flush phenomenon. However, definition and current methods of analyses of the phenomena contain serious limitations, the most important being their inability to capture a possible impact of the event size (total event volume) on the first flush. This paper presents the development of a novel approach in defining and ...

  • The influence of particle size on the first flush strength of urban stormwater runoff

    The presence of a first flush (FF) of suspended solids (SS) in stormwater runoff has important implications for the design of treatment facilities, as does the particle size of solids. Whilst numerous studies have examined the FF behaviour of SS, few have disaggregated FF trends by particle size. In this study, the FF behaviour of SS was investigated in five size ranges, sampled from an urban ...
