“…Constructed stormwater wetlands have been successfully adopted for treating runoff from a variety of catchments, including: residential communities, industrial/commercial areas, roadways, institutional campuses, apartment complexes, parking lots, stormwater retention ponds, and even to treat combined sewer discharge (Al-Rubaei et al 2016;Ávila et al 2013;Forgione 2015;Humphrey et al 2014;Lynch et al 2015;Mangangka et al 2015b). CSWs can treat a variety of stormwater pollutants, but studies have shown they preform exceptionally well at removing nutrient pollutants (Al-Rubaei et al 2016;Ávila et al 2013;Chang et al 2012;Humphrey et al 2014;Lucas et al 2015;Lucas and Babatunde 2017;Schmitt et al 2015).…”

“…Constructed stormwater wetlands can provide many benefits, including: reductions in peak flows and runoff volumes (specifically for larger volume runoff events), water quality improvements, provide a thriving ecological habitat, abilities to maintain continuous flows (both base flows and storm flows), more flood protection than lower volume BMPs, groundwater recharge (when liners are not installed), mechanically simple design, and the ability to perform well with relatively limited operating and maintenance requirements (Forgione 2015;Humphrey et al 2014;Mackintosh et al 2015;Tang et al 2017;Vacca et al 2016;Zounemat-Kermani et al 2015). Al-Rubaei et al (2016) studied whether the lack of long-term maintenance affected the performance of a CSW. The only maintenance the studied CSW had received over a period of 19 years was the removal of sediments from the forebay (Al-Rubaei et al 2016).…”

The authors found that despite a lack of regular maintenance, the CSW performed similarly to its expected design performance.…”

This study monitored the stormwater runoff quantity and quality treatment performance of a 6.8 ha 19-year old combined pond-wetland system, located in south Sweden, over one year. The mean volume reductions for 53 storm events for the pond and wetland were 40% and 28%, respectively, while the mean flow reductions were 60% and 76%, respectively. Pollutant concentrations in the influent to the wetland were highly variable. The pond-wetland system could efficiently remove an average of 91%, 80%, 94%, 91%, 83% and 92% of TSS, TP, particulate Cd, Cu, Pb, and Zn, respectively, whereas the removal of particulate and dissolved Ni was highly variable with an average of 67% ± 62% and −5% ± 41%, respectively. The removal of TN, NH 4 -N and NO 3 + NO 2 -N was highly variable with an average of 45% ± 27%, 12% ± 96% and 45% ± 43%, respectively. These removal percentages are high in comparison to other studies and underline that relatively old systems can also provide efficient treatment. Although the pond accounted for a substantial reduction of pollutant concentration, the wetland significantly enhanced both the treatment performance and the peak flow reduction. This underlines that a combined pond/wetland system is a more beneficial solution than a pond only. The pollutant removal efficiency was significantly influenced by some factors including Antecedent Dry Days, seasonal variations, air temperature, retention times, rainfall depth and duration, and peak rainfall intensity.

“…BothAl-Rubaei et al (2016) andKadlec (2016) reported a plateau in outlet concentrations at an apparent "irreducible concentration" of 4 to 30 μg P/L for CSWs ranging up to 20 years in age. Field monitoring data from of a set of mature wetlands in Florida suggested surface water P concentrations are strongly coupled to nutrient concentrations within the wetland soils and floc (Corstanje et al, 2016).…”

A summary of 246 studies published in 2016 on topics related to the characterization and management of urban stormwater runoff is presented in the following review. The review is structured along three major topical areas: (1) general characterization of stormwater quantity and quality; (2) engineered systems for stormwater control and treatment, including erosion and sediment control practices, constructed stormwater ponds and wetlands, bioretention, permeable pavement, greenroofs, and rainwater harvesting and (3) watershedscale application of stormwater treatment and control practices. Common research themes and needs highlighted throughout this review include efforts to better understand stormwater transport and treatment mechanisms and their representation in models, advancements to optimize the design of stormwater control measures to meet specific hydrologic and/or water quality targets, and increasing understanding of the biophysical and social factors that influence watershed-scale implementation of low impact development and other stormwater control measures.
