TL;DR: The results demonstrate that vegetation selection is critical to performance for nitrogen removal, and that biofilters built according to observed 'optimal specifications' can reliably remove both nutrients and suspended solids.
511 citations
TL;DR: In this paper, the authors investigated the hydrologic and pollutant removal performance of three field-scale bio-filtration systems in two different climates, and found that they were able to effectively attenuate peak runoff flow rates by at least 80%.
470 citations
TL;DR: This paper presents a review of Australian stormwater treatment and recycling practices as well as a discussion of key lessons and identified knowledge gaps, and recommendations for overcoming these knowledge gaps are given.

TL;DR: A critical review of the characteristics and sources of urban stormwater pollutants and the manner in which the pollution occurs is provided in this paper, where treatment systems for urban storm water runoff and for urban rainwater harvesting are discussed.
Abstract: Stormwater runoff from urban and suburban areas generates numerous pollutants. The areas include residential areas, parks, commercial areas, industrial areas and road/highways. Land use and human activities largely determine the nature and level of pollutants. Among the various types of pollutants that can contribute to adverse water quality impact in receiving water bodies, of concern are suspended solids, heavy metals, polycyclic aromatic hydrocarbons and nutrients. This paper provides a critical review of the characteristics and sources of urban stormwater pollutants and the manner in which the pollution occurs. Treatment systems for urban stormwater runoff and for urban stormwater harvesting are discussed.

TL;DR: Efforts to prevent or reverse hydrologic symptoms associated with the urban stream syndrome will require selecting the right mix of LID technologies that provide regionally tailored ratios of stormwater harvesting and infiltration and integrating these technologies into next-generation drainage systems.
Abstract: Catchment urbanization perturbs the water and sediment budgets of streams, degrades stream health and function, and causes a constellation of flow, water quality, and ecological symptoms collectively known as the urban stream syndrome. Low-impact development (LID) technologies address the hydrologic symptoms of the urban stream syndrome by mimicking natural flow paths and restoring a natural water balance. Over annual time scales, the volumes of stormwater that should be infiltrated and harvested can be estimated from a catchment-scale water-balance given local climate conditions and preurban land cover. For all but the wettest regions of the world, a much larger volume of stormwater runoff should be harvested than infiltrated to maintain stream hydrology in a preurban state. Efforts to prevent or reverse hydrologic symptoms associated with the urban stream syndrome will therefore require: (1) selecting the right mix of LID technologies that provide regionally tailored ratios of stormwater harvesting and infiltration; (2) integrating these LID technologies into next-generation drainage systems; (3) maximizing potential cobenefits including water supply augmentation, flood protection, improved water quality, and urban amenities; and (4) long-term hydrologic monitoring to evaluate the efficacy of LID interventions.
