“…Stormwater runoff from each of these sources can be directed by pipes and overland flow to an infiltration system (US EPA 1999). The objectives of groundwater infiltration include plans to minimize alteration of the local groundwater system arising from urbanization, to minimize the change in the hydrology of receiving water courses, and to reduce pollution discharges to surface water bodies (Duchene and McBean 1992). Infiltration trenches function similarly to rapid infiltration systems that are used in wastewater treatment and considered as a BMP for stormwater runoff control (US EPA 1999).…”

Nonpoint source pollution management initiated by the Ministry of Environment (MOE) in Korea resulted to the construction of 25 pilot facilities termed Best Management Practices (BMPs) until 2005. The national nonpoint sources control projects were employed to fulfill the Total Maximum Daily Load programs. The long-term monitoring being conducted at the sites which began in 2006 is providing detailed insight into the performance of the BMPs. The experience and performance data will be used to better understand and implement similar structural BMPs in the future as well as to assist the MOE in developing the design and maintenance guidelines of BMPs. This study presents the results gathered from the monitoring field tests and experiments over 22 rainfall events between the June 2006 and September 2008 period investigating the pollutant removal efficiency of the infiltration trench BMP that is one of the 25 pilot projects of the MOE. In addition, it includes the development of simple linear regression models to estimate constituent event mean concentration. The results reveal high treatment efficiencies for total suspended solids (89%); biochemical oxygen demand, chemical oxygen demand, and dissolved organic carbon (89-93%); oil and grease (100%); cadmium, lead, and zinc (89-93%); total nitrogen (84%); and total phosphorus (82%). The monitoring data and results will represent a step forward to a better prediction of impacts in the environment and to the national development of BMPs for sustainable watershed management in the country.

“…Rainwater detention ponds [122,123], gravel trenches [124,125], and storage trenches [126,127] can reduce the runoff speed of rainfall, increasing groundwater recharge and evapotranspiration [128,129]. Reducing rainfall runoff is effective for efficient water use [130,131].…”

As the impermeable sidewalk area increases in urban areas, diverse problems related to water occur. The purposes of this research were to increase the rainwater infiltration rate through water balance analysis and estimate the runoff coefficient according to land cover types in urban parks. The regression equations and runoff coefficients relative to the rainwater infiltration rate were estimated according to the land cover types and applied to eight urban parks. In the results of the experiment, the runoff coefficient was 0.245 for vegetation areas, 0.583 for permeable sidewalks, 0.963 for sidewalk blocks, and 1.000 for impervious sidewalks, which had 100% outflow. The results show that the vegetation area in urban parks is significantly related to rainfall–runoff, infiltration, and evapotranspiration. The average of eight urban parks was 126.52 mm, indicating that 11.80% of the rainfall was recharged into groundwater. Additionally, the average runoff rate was 498.56 mm, indicating that 46.52% was leaked externally. Therefore, it is suggested to decrease the impermeable sidewalk areas in urban parks. Additionally, extending the waterway, swamp, and gravel sidewalk areas is suggested. Urban parks should be developed in order to contribute to hydrological control through the water balance in urban land use.

“…To estimate the exfiltration rates through the perforations into the infiltration trench surrounding the lower, perforated pipe, orifice flow conditions and equations were employed (after Reference [30,31]). Calculations were then performed to determine the volume of stormwater which can exfiltrate from the perforated pipe 1.0 m below the main sewer pipe.…”

Urban stormwater management is essential to improve the management of floodwaters in municipalities in urban areas. However, relying on sponge city options for site planning in an attempt to decrease the impacts of flooding is challenging due to the magnitude of flooding in urban China. The merits of exfiltration technology being used in Canada are described as having significant potential; this technology encourages passage from the stormwater pipe down to a second, lower pipe, to facilitate exfiltration to the vadose zone and, ultimately, to replenish groundwater. For example, for a small urban catchment, stormwater runoff from a 2-h long, 5-yearly storm, is demonstrated as being able to exfiltrate approximately 53% of the stormwater. Overall, the potential exists to exfiltrate stormwater from the lower pipe and it is estimated that 71% of the water entering the storm sewer is exfiltrated to the vadose zone, for a small catchment. The exfiltration pipe technology increases groundwater recharge which provides an opportunity to help manage subsidence in China. However, attention must be paid to the quality of the infiltrating water since, as true for any sponge city initiative, poor quality infiltrating water may deteriorate the quality of the groundwater.
