Rain gardens have been recommended as a best management practice to treat stormwater runoff. However, no published field performance data existed on pollutant removal capabilities. Replicated rain gardens were constructed in Haddam, CT, to capture shingled-roof runoff. The gardens were sized to store the first 2.54 cm (1 inch) of runoff. Influent, overflow and percolate flow were measured using tipping buckets and sampled passively. Precipitation was also measured and sampled for quality. All… 

Saturation to improve pollutant retention in a rain garden.

It is suggested that high flow and pollutant retention could be achieved with the 2.54 cm design method, but the use of an underdrain could reduce overall pollutants retention.

Phosphorus leaching from substrates commonly used in rain gardens

Rain gardens are not yet a very popular solution in Poland but their number in cities is steadily growing. They are a measure of adaptation of cities to climate change. Rain gardens can be effective

Rain Gardens as Stormwater Management Tool

Stormwater runoff contributes significantly to urban flooding, groundwater pollution, reduction in water table, surface water quality impairment, etc. as it contains various pollutants that pose

'Appreciating' Drainage Assets in New Zealand Cities: Rain Garden Treatment and Hydraulic Performance

Despite recognising rain gardens as a best management practice (BMP) to mitigate urban stormwater runoff, there is a dearth of knowledge about their treatment and infiltration performance. It is

Assessment of Rain Garden Effects for the Management of Urban Storm Runoff in Japan

Storm runoff is a growing concern against a background of increasing urban densification, land-use adaptation and climate change. In this study, a storm water management model was used to analyze the

Field Performance of Bioretention Systems for Runoff Quantity Regulation and Pollutant Removal

Bioretention systems are of immense importance as they serve as small “sponges” for cities, cutting stormwater runoff, removing pollution, and using precipitation resources. However, performance data


A BSTRACT . Engineered bioretention cells with underdrains have shown water quality and hydrologic benefits for abating urban stormwater problems. Less is known about the hydrologic performance of

Contaminant removal and hydraulic conductivity of laboratory rain garden systems for stormwater treatment.

Metal removal was greater when effluent pH was elevated and provided by the calcareous sand in two of the systems, whereas the topsoil-only system lacked an alkaline source, resulting in poorer treatment due to higher dissolved metal fractions.

Factorial Study of Rain Garden Design for Nitrogen Removal

AbstractNitrate (NO3−-N) removal studies in rain gardens show great variability in removal rates, and in some cases NO3−-N was exported. A three-way factorial design (2×2×4) was devised for eight

Evaluation of pollutant removal efficiency of a bioretention basin and implications for stormwater management in tropical cities

Non-point source pollution is a prevalent problem throughout the world. Bioretention basins have been deployed worldwide to treat stormwater runoff and alleviate eutrophication in downstream water



Laboratory Study of Biological Retention for Urban Stormwater Management

Overall results support the use of bioretention as a stormwater best management practice and indicate the need for further research and development.

Engineered Bioretention for Removal of Nitrate from Stormwater Runoff

The results indicate that engineered bioretention for the removal of nitrogen from stormwater runoff has the potential for successful application as an urban stormwater treatment practice.

Behavior of Heavy Metals, Nutrients, and Major Components during Roof Runoff Infiltration

The behavior of heavy metals (Cd, Cu, Zn, Cr, Pb), nutrients (organic C, P, and N parameters), and major ions was investigated during percolation of roof runoff water through an artificial

Preliminary Observations on Water Quality of Storm Runoff From Four Selected Residential Roofs

: Storm runoff from four characteristic types of residential roofs and incident rainwater were monitored for 47 storm events over a six-month period at Nacogdoches, Texas, to study water quality

Estimation of wet, dry and bulk deposition of atmospheric nitrogen in Connecticut.

There appears to be a similar seasonal trend in wet and dry deposition fluxes of total nitrogen in Connecticut with high and low deposition fluxe occurring in summer and winter periods, respectively.
