This included data on triazines (atrazine, prometryn, and simazine), glyphosate, and chloroform during six simulated stormwater events.
Once the data is obtained, students create presentations of the data and attempt to answer the question, "What is the story of the river?" They are directed to consider the importance of a longitudinal study that would allow for more data and a more accurate picture of a river's response to stormwater events.
Concentrations increased by 5 150 times after stormwater overflow events.
The annual and single event stormwater runoff reduction from infiltration trenches was determined for 9 different scenarios that covered different soil conditions and infiltration trench dimensions.
A pre-fabricated concrete vortex unit, a sub-surface sandfilter and a raingarden, all sized to treat a functional unit of 35 m3 of stormwater runoff per event, were evaluated.
The Mayor's announcement is an important step; one that we hope will result in an even greater investment in green infrastructure, on par with cities like Milwaukee, whose regional green infrastructure plan has a goal of capturing 740 million gallons of stormwater per rain event by 2035.
Rapid urbanization and climate variability impacts increase with more extreme precipitation and drought events, challenging stormwater management in terms of both flood control and water quality.
Based on extensive field investigations in four urban residential catchments based at Gold Coast, Australia, and computer modelling, this paper details a technically robust approach for the selection of rainfall events for stormwater treatment design using a three-component model.
The knowledge created through this research study provides the ability to select appropriate rainfall events for stormwater quality treatment design based on the required treatment outcomes such as the need to target different sectors of the runoff hydrograph or pollutant species.
Under this circumstance, the follow-up non-stormwater outfall pumping events indicate misconnections between surface water and storm drains, featuring pumping discharge equivalent to surface water backflow; hence the misconnections should be repaired.
