Most recently, research on stormwater detention ponds has focused on designs and operations that will improve the water quality of the discharge. Historically stormwater detention ponds were used to reduce the rate of runoff from the watershed area of using temporary storage to attenuate flow rates.
The study site was located near Orlando, Florida, and consisted of a detention pond, namely Lake Angel, which received stormwater runoff from a 131-acre area. Hydrologic data such as precipitation, runoff, and pond outflow were measured at the site. Total and suspended solids data for the pond outflow and stormwater runoff also were collected at the site. Using these data both the hydrologic budget and solids removal efficiency of the detention pond were determined. Pond outflow was measured continuously and 319 solids determinations were made. However, all data were simulated on an hourly basis.
A computer program, STORCALC, was written to simulate inlet and outlet flow rates and solids concentrations. Groundwater inflow rates were determined from a hydrologic balance verified by water table measurements and equations for groundwater flow.
Solids removal efficiencies were determined based on concentration and mass. There was a significant difference between concentration and mass removal efficiencies, thus, it was concluded that detention ponds with groundwater inflow can have a negative removal efficiency of total and suspend solids based on the runoff and pond outflow mass while having a positive removal efficiency of total and suspended solids based on concentration.
