Constructed Floating Wetlands (CFW) for stormwater treatment are increasingly used to treat urban runoff. However, studies of large-scale systems and the long-term evaluation of their treatment efficiency are scarce. This article presents the final results of a two-year study of the pollutant removal performance of a CFW in a stormwater pond capturing runoff from a low-residential catchment in ...

The use of decentralised, sustainable urban drainage systems (SUDS) for the treatment of stormwater runoff is becoming increasingly prevalent in Germany. Decentralised SUDS can offer a viable and attractive alternative to end of pipe treatment systems for stormwater runoff from urban areas. However, there is still some uncertainty regarding the long-term performance of SUDS, and the general leg...

Analyses of regional-scale synoptics and air-mass trajectories, local-scale atmospheric measurements (wind direction and speed, air temperature, dust load, SO 2 and NO x concentrations in the air, rain amount and intensity), and chemical and isotopic compositions of rainwater collected in the coastal city of Ashdod, Israel, were used to identify the various contributing sources to rainwater sal...

Leveraging recent advances in technologies surrounding the Internet of Things, “smart” water systems are poised to transform water resources management by enabling ubiquitous real-time sensing and control. Recent applications have demonstrated the potential to improve flood forecasting, enhance rainwater harvesting, and prevent combined sewer overflows. However, adoption of smart water systems ...

The U.S. Environmental Protection Agency (EPA) requires that stormwater be controlled to the maximum extent practicable through the use of stormwater control measures. These regulations are enforced by state and local governments, who often require the use of SCMs to comply with total maximum daily loads (TMDLs). State and local governments also provide guidance on SCM design and assign load re...

The design of three stormwater treatment facilities, aiming at implementing and demonstrating technologies that efficiently reduce diffuse urban pollutant loads onto receiving waters is presented. The designs aim at reducing not only particulates, but also dissolved pollutants and pollutants associated with colloids. Unit operations that are efficient in this respect are discussed. Different te...

Urbanization has been found to impact stormwater runoff quantity and quality. A study catchment with mixed land use, residential and industrial were investigated and the water quality discharged from the catchment were sampled and tested for four basic water quality parameters; BOD5, NH3-N, NO3-N and P. One dry weather flow and several stormwater runoff were sampled. Results were compared to th...

Events that are referred to as geysers have been observed in stormwater or combined sewer systems and are associated with jets of water rising through manholes to a considerable distance above the ground surface. Visual observations suggest that air may be a significant component of the jet. The mechanisms of geyser occurrence have been previously assumed to originate in inertial oscillations t...

Abstract Stormwater control measures (SCMs) are designed according to different urban stormwater management criteria. These criteria usually the basis for conception of SCM typologies. Although these typologies useful, there is currently no typology that can generically describe all diversity SCMs and adapted modeling. Thus, a new proposed here. This based on two commonly used in management: hy...

Sorption media with mixes of some recycled materials, such as sawdust and tire crumbs, combined with sand/silt and limestone, become appealing in nutrient removal for promoting urban stormwater management with sustainability implications. This article aims to present a specific type of functionalized filter medium and examine its physicochemical process for nutrient removal with the aid of Lang...
